The stupidly effective genius of nature: Researchers discover how nature enables cells to act intelligently
From Science Daily: Researchers have discovered a Lévy walk pattern of movement when living cells eat. When the food is transported within the cell by so-called endosomal active transport, it is the same mathematical pattern of movement that many animals follow when foraging for food. A Lévy walk or flight, named after a French mathematician Paul Lévy, is a mix of long trajectories and short random movements. Numerous short movements are made within a small area, and occasionally a long stride to a distant area, where the action is repeated. This particular motion pattern is observed in humans and animals.

New math and quantum mechanics: Fluid mechanics suggests alternative to quantum orthodoxy
From Science Daily: The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what's called the "Copenhagen interpretation" -- which holds that, in some sense, a single particle really is a wave, smeared out across the universe, that collapses into a determinate location only when observed. But some founders of quantum physics -- notably Louis de Broglie -- championed an alternative interpretation, known as "pilot-wave theory," which posits that quantum particles are borne along on some type of wave. According to pilot-wave theory, the particles have definite trajectories, but because of the pilot wave's influence, they still exhibit wavelike statistics. Now a professor of applied mathematics believes that pilot-wave theory deserves a second look.

It's an application that will soon help oncologists use the mathematical model to develop treatment plans for all cancer patients.
Equation to describe competition between genes
From Science Daily: Biologists typically conduct experiments first, and then develop models afterward to show how data fit with theory. New research flips that practice on its head. A biophysicist tackles questions in cellular biology as a physicist would -- by first formulating a model that can make predictions and then testing those predictions. Using this strategy, this research group has recently developed a mathematical model that accounts for the way genes compete with each other for the proteins that regulate their expression.
Cancer cells don't take 'drunken' walks through body
From Science Daily: Biologists have believed that cancers cells spread through the body in a slow, aimless fashion, resembling a drunk who can't walk three steps in a straight line. They now know that's true in a flat petri dish, but not in the three-dimensional space of an actual body. This finding is important because it should lead to more accurate results for scientists studying how cancer spreads through the body, often leading to a grim prognosis. To address this dimensional disagreement, the study's authors have produced a new mathematical formula that they say better reflects the behavior of cells migrating through 3D environments.

Probing the edge of chaos: How do variable physical characteristics behave at the point preceding onset of chaos?
From Science Daily: The edge of chaos -- right before chaos sets in -- is a unique place. It is found in many dynamical systems that cross the boundary between a well-behaved dynamics and a chaotic one. Now, physicists have shown that the distribution -- or frequency of occurrence -- of the variables constituting the physical characteristics of such systems at the edge of chaos has a very different shape than previously reported distributions. This could help us better understand natural phenomena with a chaotic nature.
Forest model predicts canopy competition: Airborne lasers help researchers understand tree growth
From Science Daily: Scientists use measurements from airborne lasers to gauge changes in the height of trees in the forest. Tree height tells them things like how much carbon is being stored.

Researchers focused on the dynamics of natural hormone secretion and subsequent effects on the brain and other organs. Combining mathematical modelling with the latest clinical and experimental data, they found that the body regulates the release of crucial steroid hormones (such as cortisol) in pulses approximately every hour.
Better way to make sense of 'Big Data?'
From Science Daily: Big data is everywhere, and we are constantly told that it holds the answers to almost any problem we want to solve. But simply having lots of data is not the same as understanding it. New mathematical tools are needed to extract meaning from enormous data sets. Researchers now challenge the most recent advances in this field, using a classic mathematical concept to tackle the outstanding problems in big data analysis.
How evolution shapes the geometries of life
From Science Daily: An interdisciplinary team re-examined Kleiber's Law, a famous 80-year-old equation that accurately describes many biological phenomena, although scientists don't agree on why it works.

Geophysicist teams with mathematicians to describe how river rocks round
From Science Daily: For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks significantly, or is it that smaller rocks are simply more easily transported downstream? A new study has arrived at a resolution to this puzzle.

The mathematical minds of the future will need to understand how different economic, social, technological and work-related processes can be mathematically represented or modeled. A project included in the Academy of Finland's research program The Future of Learning, Knowledge and Skills (TULOS) is exploring new pedagogical practices and technological environments that can prepare students for the flexible and adaptive use of their mathematical skills in future activity environments.
Biostatistics approach to genetics yields new clues to roots of autism
From Science Daily: Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent ’pruning’ of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.
Intuitive number games boost children's math performance
From Science Daily: A quick glance at two, unequal groups of paper clips (or other objects) leads most people to immediately intuit which group has more. In a new study, researchers report that practicing this kind of simple, instinctive numerical exercise can improve children's ability to solve math problems. A report of the study appears in the journal Cognition. "We wanted to know how basic intuitions about numbers relate to mathematics development," said University of Illinois psychology professor Daniel Hyde, who conducted the study with Saeeda Khanum, of Quaid-i-Azam University in Islamabad, and Elizabeth Spelke, of Harvard University. "Specifically we wanted to know whether thinking intuitively about numbers, such as approximating and comparing sets without counting, helps in actually doing math."
New Computer Model May Aid Personalized Cancer Care
From Science Daily: Dana-Farber Cancer Institute scientists have developed a mathematical model to predict how a patient’s tumor is likely to behave and which of several possible treatments is most likely to be effective. Reporting in the journal Cell Reports, researchers combined several types of data from pre- and post-treatment biopsies of breast tumors to obtain a molecular picture of how the cancer evolved as a result of chemotherapy.
Tracing Unique Cells With Mathematics
From Science Daily: Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analyses to investigate these heterogeneities. But the method is still laborious and considerable inaccuracies conceal smaller effects. Scientists at the Helmholtz Zentrum Muenchen, at the Technische Unitversitaet Muenchen and the University of Virginia (USA) have now found a way to simplify and improve the analysis by mathematical methods.
Fever-Reducing Meds May Help Spread the Flu
From Science Daily: Contrary to popular belief, fever-reducing medication may inadvertently cause more harm than good. New research from McMaster University has discovered that the widespread use of medications that contain fever-reducing drugs may lead to tens of thousands more influenza cases, and more than a thousand deaths attributable to influenza, each year across North America. These drugs include ibuprofen, acetaminophen and acetylsalicylic acid.
New Method for Studying Social Processes Brings Clarity to Global Economic, Political Change
From Science Daily: Researchers at the Institute for Futures Studies and Uppsala University have developed a new method for studying complex social processes.

New proposal for better allocation of donated livers in transplants
From Science Daily: Researchers at the University of Cordoba (Spain) have developed a system that measures compatibility between donors and the most serious receivers in liver transplants. This is a mathematical method that includes the experience of almost 1,500 donations registered in transplant units in Spain and the United Kingdom.
Refined model for reliable prediction of invasion dynamics
From Science Daily: The question how rapidly animals, plants or microorganisms can colonize new territories is not only of interest to ecologists -- the spread of invasive species can also have economic consequences, e.g. in the agricultural sector. Scientists at Eawag and the EPF Lausanne have now refined an existing model and, for the first time, used laboratory experiments to validate its ability to predict biological invasion dynamics.
25 Years of DNA On Computers
From Science Daily: DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesises proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA by observing it experimentally with a variety of techniques, which have only recently been supplemented by research in silico, that is to say, the study of DNA by means of computer simulations. This is a recent area of study, but it has already given a major contribution to knowledge in this field.
Soap Bubbles for Predicting Cyclone Intensity?
From Science Daily: Could soap bubbles be used to predict the strength of hurricanes and typhoons? However unexpected it may sound, this question prompted physicists at the Laboratoire Ondes et Mati’re d'Aquitaine (CNRS/universit’ de Bordeaux) to perform a highly novel experiment: they used soap bubbles to model atmospheric flow. A detailed study of the rotation rates of the bubble vortices enabled the scientists to obtain a relationship that accurately describes the evolution of their intensity, and propose a simple model to predict that of tropical cyclones.
Using Maths, Researchers Seek to Improve Success in Transplants
From Science Daily: Given that 10.5 % of patients who receive a transplant reject the new organ, researchers at the Center of Research and Advanced Studies of the National Polytechnic Institute (Cinvestav) are working in the design of a tool capable of preventing this problem. The process consists in knowing the type of proteins in charge of metabolizing the drugs (enzymes) for each patient which would, helped by a mathematical model, allow to establish the exact dose needed of the immunosuppressive drugs required.
Variation in Adolescents Skills in Addition to Earlier Mathematics Skills Is Strongly Accounted for by Literacy Skills, Beliefs in Oneself as Mathematics Learner and Mathematical Task-Orientation
From Science Daily: Right after the PISA-results were published the whole Finland turned upside down. The performance of Finnish adolescents in mathematics had dropped from the very high end to 12th place. It started a discussion on bringing back the importance of motivation and "fun" in learning mathematics. The problem among our adolescents is that they are not very motivated towards school in general, whereas many of them also have specific lack of motivation towards learning and comprehending mathematics. However, Finnish adolescents still have a good learning potential, it just has to be re-accelerated and nourished.
In Addiction, Meditation Is Helpful When Coupled With Drug, Cognitive Therapies
From Science Daily: Using a computational model of addiction, a literature review and an in silico experiment, theoretical computer scientist Yariv Levy and colleagues suggest in a new paper this week that rehabilitation strategies coupling meditation-like practices with drug and behavior therapies are more helpful than drug-plus-talk therapy alone when helping people overcome addiction.
Kids Grasp Large Numbers Remarkably Young
From Science Daily: Children as young as 3 understand multi-digit numbers more than previously believed and may be ready for more direct math instruction when they enter school, according to research led by a Michigan State University education scholar.
No Math Gene: Learning Mathematics Takes Practice
From Science Daily: New research from the Norwegian University of Science and Technology shows that if you want to be good at math, you have to practice all different kinds of mathematics. What makes someone good at math? A love of numbers, perhaps, but a willingness to practice, too. And even if you are good at one specific type of math, you can't trust your innate abilities enough to skip practicing other types if you want to be good. New research at the Norwegian University of Science and Technology (NTNU) in Trondheim could have an effect on how math is taught. If you want to be really good at all types of math, you need to practice them all. You can't trust your innate natural talent to do most of the job for you.
Simple Mathematical Formula Describes Human Struggles
From Science Daily: Would you believe that a broad range of human struggles can be understood by using a mathematical formula? From child-parent struggles to cyber-attacks and civil unrest, they can all be explained with a simple mathematical expression called a "power-law."
Using Air Transportation Data to Predict Pandemics
From Science Daily: Computational work conducted at Northwestern University has led to a new mathematical theory for understanding the global spread of epidemics. The resulting insights could not only help identify an outbreak's origin but could also significantly improve the ability to forecast the global pathways through which a disease might spread.
Evolution of 'Third Party Punishment'
From Science Daily: You're shopping for holiday gifts when you spot someone pocketing a nice pair of leather gloves. What do you do? A new study by University of Maryland researchers appearing this week in the Proceedings of the Royal Society B predicts that whether you alert a manager to the theft or decide to do nothing may depend on whether you're shopping in a local store where you know the owners or in a city far from home.
Math Models Enhance Current Therapies for Coronary Heart Disease
From Science Daily: Coronary heart disease accounts for 18% of deaths in the United States every year. The disease results from a blockage of one or more arteries that supply blood to the heart muscle. This occurs as a result of a complex inflammatory condition called artherosclerosis, which leads to progressive buildup of fatty plaque near the surface of the arterial wall. In a paper published last month in the SIAM Journal on Applied Mathematics, authors Sean McGinty, Sean McKee, Roger Wadsworth, and Christopher McCormick devise a mathematical model to improve currently-employed treatments of coronary heart disease (CHD).
Forget the Needle; Consider the Haystack
From Science Daily: Advances in computer storage have created collections of data so huge that researchers often have trouble uncovering critical patterns in connections among individual items, making it difficult for them to realize fully the power of computing as a research tool. Now, computer scientists at Princeton University have developed a method that offers a solution to this data overload. Using a mathematical method that calculates the likelihood of a pattern repeating throughout a subset of data, the researchers have been able to cut dramatically the time needed to find patterns in large collections of information such as social networks. The tool allows researchers to identify quickly the connections between seemingly disparate groups such as theoretical physicists who study intermolecular forces and astrophysicists researching black holes.
Art Could Help Create a Better 'STEM' Student

Can iPads Help Students Learn Science? Yes, Study Shows
From Science Daily: The scale of the universe can be difficult to comprehend. Pretend you are going to make a scale model with a basketball representing Earth and a tennis ball as the Moon. How far would you hold the tennis ball "Moon" from the basketball "Earth?" Most people would hold them at arm's length from each other, but the answer may surprise you: at that scale the balls would need to be held almost 30 feet apart.
Study Highlights Massive Benefits of HIV Treatment in South Africa
From Science Daily: Antiretroviral therapy (ART) for the treatment of HIV infection has saved 2.8 million years of life in South Africa since 2004 and is projected to save an additional 15.1 million years of life by 2030, according to a new study published online in The Journal of Infectious Diseases. The analysis suggests these dramatic benefits could be even greater if more aggressive HIV testing and treatment strategies are implemented.
The Oracle of the T Cell
From Science Daily: A platform that simulates how the body defends itself: The T cells of the immune system decide whether to trigger an immune response against foreign substances. Since December 2013, scientists from around the world can use the "virtual T cell" to test for themselves what happens in the blood cell when receptor proteins are activated on the surface. Prof. Dr. Wolfgang Schamel from the Institute of Biology III, Facutly of Biology, the Cluster of Excellence BIOSS Centre for Biological Signalling Studies and the Center of Chromic Immunodeficiency of the University of Freiburg is coordinating the European Union-funded project SYBILLA, "Systems Biology of T-Cell Activation in Health and Disease." This consortium of 17 partners from science and industry has been working since 2008 to understand the T cell as a system. Now the findings of the project are available to the public on an interactive platform. Simulating the signaling pathways in the cell enables researchers to develop new therapeutic approaches for cancer, autoimmune diseases, and infectious diseases.
In the Case of Wholesale Food Distributors, It's All About Location
From Science Daily: In all but the shortest supply chains, food travels through wholesale distribution centers on its way from farm to consumer, and the location of these distributors can have a big impact on the efficiency of a food system. Now, a new mathematical model can help business owners and policy makers determine the optimal locations for such distributors, thanks to a research team led by an engineer in Penn State's College of Agricultural Sciences.
No Qualms About Quantum Theory
From Science Daily: A colloquium paper published in The European Physical Journal D looks into the alleged issues associated with quantum theory. Berthold-Georg Englert from the National University of Singapore reviews a selection of the potential problems of the theory. In particular, he discusses cases when mathematical tools are confused with the actual observed sub-atomic scale phenomena they are describing. Such tools are essential to provide an interpretation of the observations, but cannot be confused with the actual object of studies.
ADHD Study: Expensive Training Programs Don't Help Grades, Behavior
From Science Daily: Many parents spend thousands of dollars on computer-based training programs that claim to help children with ADHD succeed in the classroom and in peer relationships while reducing hyperactivity and inattentiveness. But a University of Central Florida researcher says parents are better off saving their hard-earned cash.
Selecting Mathematical Models With Greatest Predictive Power: Finding Occam's Razor in an Era of Information Overload
From Science Daily: How can the actions and reactions of proteins so small or stars so distant they are invisible to the human eye be accurately predicted? How can blurry images be brought into focus and reconstructed? A new study led by physicist Steve Press’, Ph.D., of the School of Science at Indiana University-Purdue University Indianapolis, shows that there may be a preferred strategy for selecting mathematical models with the greatest predictive power. Picking the best model is about sticking to the simplest line of reasoning, according to Press’. His paper explaining his theory is published online this month in Physical Review Letters.
HIV Virus Spread, Evolution Studied Through Computer Modeling
From Science Daily: Researchers at Los Alamos National Laboratory are investigating the complex relationships between the spread of the HIV virus in a population (epidemiology) and the actual, rapid evolution of the virus (phylogenetics) within each patient's body.
Math and Juggling Lead to Better Problem-Solving Tools, Professor Says
From Science Daily: Steve Butler casually tosses a ball from his left hand to his right to demonstrate his point that anyone can juggle. With just one ball it's easy, until he changes it up and adds a second and a third ball to the mix. Still, the assistant professor of mathematics at Iowa State University says the secret to juggling is simple -- it's all about patterns.
Von Neumann-Day Problem: Vexing Math Problem Finds an Elegant Solution
From Science Daily: A famous math problem that has vexed mathematicians for decades has met an elegant solution by Cornell University researchers. Graduate student Yash Lodha, working with Justin Moore, professor of mathematics, has described a geometric solution for the von Neumann-Day problem, first described by mathematician John von Neumann in 1929.
What Water Looks Like to DNA
From Science Daily: A team of biochemists and mathematicians have developed a sophisticated geometric model to predict how a biological molecule will interact with water molecules, computing the results up to 20 times faster than other existing approaches. This new approach may help researchers find new drugs to treat human diseases, said the team, who described their theoretical approach in The Journal of Chemical Physics, which is produced by AIP Publishing.
Computer Scientists Create New 3-D Technique
From Science Daily: UT Dallas computer scientists have developed a technique to create 3-D images that finds practical applications of a theory created by a famous mathematician. This technique uses anisotropic triangles -- triangles with sides that vary in length depending on their direction -- to create 3-D "mesh" computer graphics of more accurate approximations of the shape of the original object, and in a shorter amount of time than current techniques. These types of images are used in movies, video games and computer modeling of various phenomena, such as the flow of water or air across the earth, the deformation and wrinkles of clothes on the human body, or in mechanical and other types of engineering designs. Researchers hope this technique will also lead to greater accuracy in models of human organs to more effectively treat human diseases, such as cancer.
Mathematical Analysis Helps Untangle Bacterial Chromosomes
From Science Daily: When an E. coli cell divides, it must replicate its circular chromosome and pull the resulting circles apart to take up residence in two new cells. It sounds easy enough -- like a magician's trick with rings -- but actually involves a complicated process of unknotting and unlinking of tangled DNA.In a new study, published online this week in the journal Proceedings of the National Academy of Sciences, SF State Associate Professor of Mathematics Mariel Vazquez and an international team of scientists offer a mathematical analysis of how these chromosomal rings are unlinked by XerCD recombination enzymes.
Educational Video Games Can Boost Motivation to Learn
From Science Daily: Math video games can enhance students' motivation to learn, but it may depend on how students play, researchers at New York University and the City University of New York have found in a study of middle-schoolers. While playing a math video game either competitively or collaboratively with another player -- as compared to playing alone -- students adopted a mastery mindset that is highly conducive to learning. Moreover, students' interest and enjoyment in playing the math video game increased when they played with another student.
Creatures of Influence
From Science Daily: In the children's game "Jenga," removing the wrong block from a tower of wooden blocks can cause the entire tower to collapse. In the same way, removing certain species from an ecosystem can cause a collapse in ecological function. A common scientific question has been to identify these critical species in different ecosystems and an international research team has developed mathematical tools that can estimate which species are most influential in a food web.
Eliminating Unexplained Traffic Jams: New Algorithm to Alleviate Traffic Flow Instabilities
From Science Daily: Everybody's experienced it: a miserable backup on the freeway, which you think must be caused by an accident or construction, but which at some point thins out for no apparent reason. Such "traffic flow instabilities" have been a subject of scientific study since the 1930s, but although there are a half-dozen different ways to mathematically model them, little has been done to prevent them.
Are you ready to retire?
From Science Daily: In a paper published last month in the SIAM Journal on Applied Mathematics, authors Carmen Calvo-Garrido, Andrea Pascucci, and Carlos V’zquez present a partial differential equation (PDE) model governing the value of a defined pension plan including the option for early retirement.
Spatial, Written Language Skills Predict Math Competence
From Science Daily: Early math skills are emerging as important to later academic achievement. As many countries seek to strengthen their workforces in the STEM (science, technology, engineering, and mathematics) fields, understanding the early contributions to math skills becomes increasingly vital. New longitudinal research from Finland has found that children's early spatial skills and knowledge of written letters, rather than oral language skills, predict competence in this area.
Baby's Innate Number Sense Predicts Future Math Skill
From Science Daily: Babies who are good at telling the difference between large and small groups of items even before learning how to count are more likely to do better with numbers in the future, according to new research from the Duke Institute for Brain Sciences.
The Math Says Red Sox Have a Big Edge in the World Series
From Science Daily: Now that the World Series is about to begin, NJIT math professor Bruce Bukiet has announced the probability of each of the contenders winning the best 4 out of 7 game contest. "The Boston Red Sox have a nearly 70% chance of winning the series," says Bukiet. But he gives the caveat that the St. Louis Cardinals have defeated both the competition and his mathematical model in each of their previous series.
Mathematical Study of Photosynthesis Clears the Path to Developing New Super-Crops
From Science Daily: How some plant species evolved super-efficient photosynthesis had been a mystery. Now, scientists have identified what steps led to that change. Using a mathematical analysis, the authors uncovered a number of tiny changes in the plants' physiology that, when combined, allow them to grow more quickly; using a third as much water as other plants; and capture around thirteen times more carbon dioxide from the atmosphere.
New Analysis of US Elementary School Mathematics Finds Half-Century of Problematic 'Strands' Structure
From Science Daily: During the "New Math" movement of the 1960s, a team of mathematicians developed a new structure for elementary mathematics. Instead of having a single subject, namely, school arithmetic, as its central core, this new structure instead had eight "strands" that were supposed to tie together elementary mathematics content. The strands structure has persisted to this day. In an article in the November 2013 issue of the Notices of the American Mathematical Society, Liping Ma argues that the strands structure has significantly weakened U.S. school mathematics.
How Earth’s Rotation Affects Vortices in Nature, Such as Hurricanes and Ocean Currents
From Science Daily: What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved axis. Understanding how geophysical (natural world) vortices behave can be critical for tasks such as weather forecasting and environmental pollution monitoring.
Math-Based Projections for MLB Postseason
From Science Daily: Now that Major League Baseball's regular season has ended with the exciting one-game tiebreaker that got the Rays to the next round, and with the Rays and the Pirates winning the one game playoff for the wild card team, NJIT math professor Bruce Bukiet has once again begun analyzing the probability of each team advancing through each round of baseball's postseason.
Peer Pressure's Influence Calculated by Mathematician
From Science Daily: A mathematician has calculated how peer pressure influences society. Professor Ernesto Estrada, of the University of Strathclyde's Department of Mathematics and Statistics, examined the effect of direct and indirect social influences -- otherwise known as peer pressure -- on how decisions are reached on important issues. Using mathematical models, he analysed data taken from 15 networks -- including US school superintendents and Brazilian farmers -- to outline peer pressure's crucial role in society.
Gender Barriers, Not Families, to Blame for Shortage of Women in Science, Technology, Engineering and Math Careers
From Science Daily: Researchers at the University of Texas-Austin and Cornell University have published a new study examining the factors behind the shortage of women in science, technology, engineering and math (STEM) fields. They find no evidence that women are opting out of the STEM workforce to start families, in contrast to the widespread perception that family factors account for the lack of women in STEM-related careers.
Unlocking Biology With Math
From Science Daily: Scientists at USC have created a mathematical model that explains and predicts the biological process that creates antibody diversity -- the phenomenon that keeps us healthy by generating robust immune systems through hypermutation.
Educational Game Uses Architectural Design to Teach Math Skills
From Science Daily: Rebuilding a city from the ground up requires math skills, knowledge of architectural design, common sense and an appreciation for what residents need and want from their city. It can also be fun. Florida State University College of Education’s Fengfeng Ke, an assistant professor in the Educational Psychology and Learning Systems department, is creating a computer game called Earthquake Rebuild that encourages creativity in design and uses architecture to teach geometry and other math skills. Ke and her team of fellow educators have been awarded a $549,937 National Science Foundation grant to support the creation of this game-based learning platform.
Researchers Successfully Test Model for Implant Device Reactions
From Science Daily: A team from the University of Texas at Arlington has used mathematical modeling to develop a computer simulation they hope will one day improve the treatment of dangerous reactions to medical implants such as stents, catheters and artificial joints.
Math Explains History: Simulation Accurately Captures the Evolution of Ancient Complex Societies
From Science Daily: The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world. Intense warfare is the evolutionary driver of large complex societies, according to new research from a trans-disciplinary team at the University of Connecticut, the University of Exeter in England, and the National Institute for Mathematical and Biological Synthesis (NIMBioS). The study appears this week as an open-access article in the journal Proceedings of the National Academy of Sciences.
New Teaching Method Improves Math Skills, Closes Gender Gap in Young Students
From Science Daily: When early elementary math teachers ask students to explain their problem-solving strategies and then tailor instruction to address specific gaps in their understanding, students learn significantly more than those taught using a more traditional approach. This was the conclusion of a yearlong study of nearly 5,000 kindergarten and first-grade students conducted by researchers at Florida State University.
Americans Grade Math as the Most Valuable School Subject
From Gallup Politics: Math is the clear winner when Americans are asked to say which school subject has been most valuable to them in their lives, followed by language arts -- English, literature, or reading -- and science. Math and English were also the top two subjects when Gallup first asked this question in 2002.
How to Fall in Love with Math
From The New York Times: EACH time I hear someone say, ’Do the math,’ I grit my teeth. Invariably a reference to something mundane like addition or multiplication, the phrase reinforces how little awareness there is about the breadth and scope of the subject, how so many people identify mathematics with just one element: arithmetic. Imagine, if you will, using, ’Do the lit’ as an exhortation to spell correctly.
Non-Traditional Mathematics Curriculum Results in Higher Standardized Test Scores
From Science Daily: For many years, studies have shown that American students score significantly lower than students worldwide in mathematics achievement, ranking 25th among 34 countries. Now, researchers from the University of Missouri have found high school students in the United States achieve higher scores on a standardized mathematics test if they study from a curriculum known as integrated mathematics.
iPad App Teaches Students Key Skill for Success in Math, Science, Engineering
From Science Daily: Engineers at the University of California, San Diego, have developed an iPad app that helps students learn spatial visualization, an essential skill for doing well in science, math and engineering. They have been testing the app during a high school summer program at the Jacobs School of Engineering at UC San Diego, as well as on undergraduate students at the school.
Tracking Criminal Movement Using Math
From Science Daily: One way to study criminal behavior and predict a criminal's next move is by analyzing his or her movement. Several mathematical models have addressed this in detail, in particular, the UCLA "burglary hotspot" model, also the topic of a previous Nugget published by the Society for Industrial and Applied Mathematics (SIAM).
Robots Take Over Economy: Sudden Rise of Global Ecology of Interacting Robots Trade at Speeds Too Fast for Humans
From Science Daily: Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this "ultrafast machine ecology" is documented in a new study published on September 11 in Nature Scientific Reports.
Arresting Model Stops Cars
From Science Daily: Researchers in China have developed a mathematical model that could help engineers design a flexible vehicle-arrest system for stopping cars involved in criminal activity or terrorism, such as suspect car bombers attempting break through a check point, without wrecking the car or killing the occupants.
The STEM Crisis Is a Myth
From IEEE Spectrum: You must have seen the warning a thousand times: Too few young people study scientific or technical subjects, businesses can’t find enough workers in those fields, and the country’s competitive edge is threatened. It pretty much doesn’t matter what country you’re talking about’the United States is facing this crisis, as is Japan, the United Kingdom, Australia, China, Brazil, South Africa, Singapore, India’the list goes on. In many of these countries, the predicted shortfall of STEM (short for science, technology, engineering, and mathematics) workers is supposed to number in the hundreds of thousands or even the millions. A 2012 report by President Obama’s Council of Advisors on Science and Technology, for instance, stated that over the next decade, 1 million additional STEM graduates will be needed. In the U.K., the Royal Academy of Engineering reported last year that the nation will have to graduate 100 000 STEM majors every year until 2020 just to stay even with demand. Germany, meanwhile, is said to have a shortage of about 210 000 workers in what’s known there as the MINT disciplines’mathematics, computer science, natural sciences, and technology.
How Vegetation Competes for Rainfall in Dry Regions
From Science Daily: The greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is a limited resource in many dry ecosystems, such as semi-arid environments and semi-deserts, there is a benefit to vegetation to adapt by forming closer networks with little space between plants. Hence, vegetation in semi-arid environments (or regions with low rainfall) self-organizes into patterns or "bands." The pattern formation occurs where stripes of vegetation run parallel to the contours of a hill, and are interlaid with stripes of bare ground. Banded vegetation is common where there is low rainfall. In a paper published last month in the SIAM Journal on Applied Mathematics, author Jonathan A. Sherratt uses a mathematical model to determine the levels of precipitation within which such pattern formation occurs.
Generosity Leads to Evolutionary Success, Biologists Show
From Science Daily: With new insights into the classical game theory match-up known as the "Prisoner's Dilemma," University of Pennsylvania biologists offer a mathematically based explanation for why cooperation and generosity have evolved in nature. Their work builds upon the seminal findings of economist John Nash, who advanced the field of game theory in the 1950s, as well as those of computational biologist William Press and physicist-mathematician Freeman Dyson, who last year identified a new class of strategies for succeeding in the Prisoner's Dilemma.
Matroid Theory: Mathematicians Solves 40-Year-Old Problem
From Science Daily: A team of mathematicians has solved a problem first posed more than 40 years ago that has confounded modern mathematicians, until now. Professor Jim Geelen of the University of Waterloo and his colleagues, Professor Bert Gerards of Centrum Wiskunde & Informatica and the University of Maastricht in the Netherlands, and Professor Geoff Whittle of Victoria University of Wellington in New Zealand have proved the famous Rota's Conjecture. The three men worked for almost 15 years to solve this problem posed by the famous mathematician and philosopher Gian-Carlo Rota in 1970. Earlier this year, in Waterloo, the trio completed the final step in their epic project.
Do Girls Really Experience More Math Anxiety?
From Science Daily: Girls report more math anxiety on general survey measures but are not actually more anxious during math classes and exams, according to new research forthcoming in Psychological Science, a journal of the Association for Psychological Science.
New Energy Model Offers Transparency to Let Others Replicate Findings
From Science Daily: Computer models are used to inform policy decisions about energy, but existing models are generally "black boxes" that don't show how they work, making it impossible for anyone to replicate their findings. Researchers from North Carolina State University have developed a new open-source model and are sharing the data they put into it, to allow anyone to check their work -- an important advance given the environmental and economic impact of energy policy decisions.
Fractions Gain Traction With Real-Life Models
From Science Daily: If 3 is greater than 2, then ⅓ must be bigger than ’ ’ -- right? Wrong. As thousands of students head back to school next week, many will use exactly that kind of thinking when faced with fractions for the first time. New research from Concordia University shows that for children to understand math, teachers must constantly make the connection between abstract numbers and real world examples.
Rethinking Investment Risk
From Science Daily: Does financial innovation inherently lead to greater risk in markets? An MIT economist takes a new look at the problem and says it does. Financial innovation is supposed to reduce risk -- in theory, at least. Yes, new financial instruments based on the housing market helped cause the financial crisis of 2008. But in the abstract, those same instruments have the potential to spread risk more evenly throughout the marketplace by making it possible to trade debt more extensively, rather than having it concentrated in a relatively few hands.
Stabilizing Aircraft During Takeoff and Landing Using Math
From Science Daily: One of the lesser known concerns about commercial aircraft is their stability on the ground during taxiing, takeoff, and landing. During these processes, planes must maintain stability under various operating conditions. However, in some situations, the aircraft landing gear displays unwanted oscillations, which are referred to as shimmy oscillations. In a paper published last month in the SIAM Journal on Applied Dynamical Systems, authors Chris Howcroft, Bernd Krauskopf, Mark Lowenberg, and Simon Neild study the dynamics of aircraft landing gear using nonlinear models. The dynamics of landing gear shimmy and the wheel-ground interaction are fundamentally nonlinear.
Computer Can Read Letters Directly from the Brain
From Science Daily: By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers from Radboud University Nijmegen have succeeded in determining which letter a test subject was looking at.
Answering Critical Questions to Respond to Anthrax Attack
From Science Daily: If terrorists targeted the United States with an anthrax attack, health care providers and policy makers would need key information -- such as knowing the likelihood of an individual becoming infected, how many cases to expect and in what pattern, and how long to give antibiotics -- to protect people from the deadly bacteria.
Preschoolers Inability to Estimate Quantity Relates to Later Math Difficulty
From Science Daily: Preschool children who showed less ability to estimate the number of objects in a group were 2.4 times more likely to have a later mathematical learning disability than other young people, according to a team of University of Missouri psychologists. Parents may be able to help their children develop their skills at approximating group sizes by emphasizing numerals while interacting with young children.
Shadows and Light: New Software to Detect Forged Photos
From Science Daily: Dartmouth and UC Berkeley researchers have developed new software to detect faked photos, using a geometric algorithm to locate inconsistent shadows that are not obvious to the naked eye. The new method debunks claims that the Apollo 11 lunar landing photo is fake.
Practice at 'Guesstimating' Can Speed Up Math Ability
From Science Daily: A person's math ability can range from simple arithmetic to calculus and abstract set theory. But there's one math skill we all share: a primitive ability to estimate and compare quantities without counting, like when choosing a checkout line at the grocery store. Previous studies have suggested there's a connection between how well a person does at the approximate number system and how skilled they become at the symbolic math they learn in school. Duke University researchers wanted to know if this ability could be enhanced by giving people more practice at approximate number math.
Simple Math Sheds New Light On a Long-Studied Biological Process

Early Spatial Reasoning Predicts Later Creativity and Innovation, Especially in STEM Fields
From Science Daily: Exceptional spatial ability at age 13 predicts creative and scholarly achievements more than 30 years later, according to results from a Vanderbilt University longitudinal study, published today in Psychological Science, a journal of the Association for Psychological Science. The study, conducted by David Lubinski and colleagues at Vanderbilt University Peabody College of education and human development, provides evidence that early spatial ability -- the skill required to mentally manipulate 2D and 3D objects -- predicts the development of new knowledge, and especially innovation in science, technology, engineering and mathematics (STEM) domains, above and beyond more traditional measures of mathematical and verbal ability.
The Universe or the Brain: Where Does Math Originate?
From Science Daily: Math describes and predicts the world all around us -- from the helical structure of DNA to the spirals of galaxies. But does this mean our world is inherently mathematical? The question has become a hot topic of debate as neuroscientists continue to uncover mathematical abilities we seem to be born with, and have pinpointed regions in the brain responsible for mathematical thinking. "[N]umbers are not properties of the universe, but rather they reflect the biological grounding for how people make sense of the world," says Rafael N’’ez, professor of cognitive science at the University of California, San Diego and member of UCSD's Kavli Institute for Brain and Mind.

Math Game More Effective Than Paper Exercises
From Science Daily: To measure the effectiveness of Monkey Tales, a study was carried out with 88 second grade pupils divided into three groups. One group was asked to play the game for a period of three weeks while the second group had to solve similar math exercises on paper and a third group received no assignment. The math performance of the children was measured using an electronic arithmetic test before and after the test period. When results were compared, the children who had played the game provided significantly more correct answers: 6% more than before, compared to only 4% for the group that made traditional exercises and 2% for the control group. In addition, both the group that played the game and that which did the exercises were able to solve the test 30% faster while the group without assignment was only 10% faster.
Teacher Collaboration, Professional Communities Improve Many Elementary School Students' Math Scores
From Science Daily: Many elementary students' math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don't spend all of their elementary school years in these settings, a new study by UNC Charlotte researchers shows. The U.S. Department of Education funded the study, which the journal Sociology of Education recently published.

Math Technique De-Clutters Cancer-Cell Data, Revealing Tumor Evolution, Treatment Leads
From Science Daily: In our daily lives, clutter is something that gets in our way, something that makes it harder for us to accomplish things. For doctors and scientists trying to parse mountains of raw biological data, clutter is more than a nuisance; it can stand in the way of figuring out how best to treat someone who is very sick. Using increasingly cheap and rapid methods to read the billions of "letters" that comprise human genomes -- including the genomes of individual cells sampled from cancerous tumors -- scientists are generating far more data than they can easily interpret.
Spooky Action Put to Order: Different Types of 'Entanglement' Classified
From Science Daily: "I think I can safely say that nobody understands quantum mechanics." Thus spoke the American physicist Richard Feynman -- underlining that even leading scientists struggle to develop an intuitive feeling for quantum mechanics. One reason for this is that quantum phenomena often have no counterpart in classical physics. A typical example is the quantum entanglement: Entangled particles seem to directly influence one another, no matter how widely separated they are. It looks as if the particles can 'communicate' with one another across arbitrary distances. Albert Einstein, famously, called this seemingly paradoxical behaviour "spooky action at a distance."
Pendulum Swings Back On 350-Year-Old Mathematical Mystery
From Science Daily: A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, University of Pittsburgh researchers report. The mystery dates back to 1665, when Dutch mathematician, astronomer, and physicist Christiaan Huygens, inventor of the pendulum clock, first observed that two pendulum clocks mounted together could swing in opposite directions. The cause was tiny vibrations in the beam caused by both clocks, affecting their motions.
Using Math to Kill Cancer Cells
From Science Daily: Here's a good reason to pay attention in math class. Today Nature Communications has published a paper from Ottawa researchers outlining how advanced mathematical modelling can be used in the fight against cancer. The technique predicts how different treatments and genetic modifications might allow cancer-killing, oncolytic viruses to overcome the natural defences that cancer cells use to stave off viral infection.
Cities Are a New Kind of Complex System: Part Social Reactor, Part Network
From Science Daily: Cities have long been likened to organisms, ant colonies, and river networks. But these and other analogies fail to capture the essence of how cities really function. New research by Santa Fe Institute Professor Luis Bettencourt suggests a city is something new in nature -- a sort of social reactor that is part star and part network, he says.
Biological Arithmetic: Plants Do Sums to Get Through the Night
From Science Daily: New research shows that to prevent starvation at night, plants perform accurate arithmetic division. The calculation allows them to use up their starch reserves at a constant rate so that they run out almost precisely at dawn. "This is the first concrete example in a fundamental biological process of such a sophisticated arithmetic calculation." said mathematical modeller Professor Martin Howard from the John Innes Centre.
Spatial Training Boosts Math Skills
From Science Daily: Training young children in spatial reasoning can improve their math performance, according to a groundbreaking study from Michigan State University education scholars. The researchers trained 6- to 8-year-olds in mental rotation, a spatial ability, and found their scores on addition and subtraction problems improved significantly. The mental rotation training involved imagining how two halves of an object would come together to make a whole, when the halves have been turned at an angle.
Computer Models Shed New Light On Sickle Cell Crisis
From Science Daily:Using powerful computer models, researchers from Brown University have shown for the first time how different types of red blood cells interact to cause sickle cell crisis, a dangerous blockage of blood flow in capillaries that causes searing pain and tissue damage in people with sickle cell disease. The models showed that the rigid, crescent-shaped red blood cells that are the hallmark of sickle cell disease don't cause these blockages on their own. Instead, softer, deformable red blood cells known as SS2 cells start the process by sticking to capillary walls. The rigid sickle-shaped cells then stack up behind the SS2s, like traffic behind a car wreck.
Researchers Track Facial Expressions to Improve Teaching Software

Monkey Math: Baboons Show Brain's Ability to Understand Numbers
From Science Daily: Opposing thumbs, expressive faces, complex social systems: it's hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait -- the ability to understand numbers -- also is shared by humans and their primate cousins. "The human capacity for complex symbolic math is clearly unique to our species," says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester. "But where did this numeric prowess come from? In this study we've shown that non-human primates also possess basic quantitative abilities. In fact, non-human primates can be as accurate at discriminating between different quantities as a human child."
Early Math and Reading Ability Linked to Job and Income in Adulthood
From Science Daily: Math and reading ability at age 7 may be linked with socioeconomic status several decades later, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The childhood abilities predict socioeconomic status in adulthood over and above associations with intelligence, education, and socioeconomic status in childhood.
Mathematical Model Measures Hidden HIV
From Science Daily: Scientists have long believed that measuring the amount of HIV in a person's blood is an indicator of whether the virus is actively reproducing.

Fast and Painless Way to Better Mental Arithmetic? Yes, There Might Actually Be a Way
From Science Daily: In the future, if you want to improve your ability to manipulate numbers in your head, you might just plug yourself in. So say researchers who report in the Cell Press journal Current Biology on May 16 on studies of a harmless form of brain stimulation applied to an area known to be important for math ability. "With just five days of cognitive training and noninvasive, painless brain stimulation, we were able to bring about long-lasting improvements in cognitive and brain functions," says Roi Cohen Kadosh of the University of Oxford.
Most Math Being Taught in Kindergarten Is Old News to Students
From Science Daily: Kindergarten teachers report spending much of their math instructional time teaching students basic counting skills and how to recognize geometric shapes -- skills the students have already mastered before ever setting foot in the kindergarten classroom, new research finds. The findings reveal a misalignment between what the students are being taught and what they already know. "This study is one of the first to raise the question: Is the content that teachers report teaching in kindergarten meeting the needs of the majority of their students?" Mimi Engel, assistant professor of public policy and education at Vanderbilt's Peabody College and lead author of the study, said.
Computational Tool Translates Complex Data Into Simplified Two-Dimensional Images
From Science Daily: In their quest to learn more about the variability of cells between and within tissues, biomedical scientists have devised tools capable of simultaneously measuring dozens of characteristics of individual cells. These technologies have led to new challenges, however, as scientists now struggle with how to make sense of the resulting trove of data. Now a solution may be at hand. Researchers at Columbia University and Stanford University have developed a computational method that enables scientists to visualize and interpret "high-dimensional" data produced by single-cell measurement technologies such as mass cytometry.
Einstein's 'Spooky Action' Common in Large Quantum Systems
From Science Daily: Entanglement is a property in quantum mechanics that seemed so unbelievable and so lacking in detail that, 66 years ago this spring, Einstein called it "spooky action at a distance." But a mathematician at Case Western Reserve University and two of his recent PhD graduates show entanglement is actually prevalent in large quantum systems and have identified the threshold at which it occurs.

Mathematical Models to Better Combat HIV
From Science Daily: The first few hours to days following exposure to human immunodeficiency virus (HIV) can be of critical importance in determining if infection occurs in a patient. But the low numbers of viruses and infected cells at this stage makes it very difficult to study these events in humans or animal models. Theoretical mathematical models can help analyze viral dynamics in this early phase, and hence offer insights into therapeutic and prevention strategies, as evidenced by a paper published last month in the SIAM Journal on Applied Mathematics.
Surges in Latent Infections: Mathematical Analysis of Viral Blips
From Science Daily:Recurrent infection is a common feature of persistent viral diseases. It includes episodes of high viral production interspersed by periods of relative quiescence. These quiescent or silent stages are hard to study with experimental models. Mathematical analysis can help fill in the gaps. In a paper titled Conditions for Transient Viremia in Deterministic in-Host Models: Viral Blips Need No Exogenous Trigger, published last month in the SIAM Journal on Applied Mathematics, authors Wenjing Zhang, Lindi M. Wahl, and Pei Yu present a model to study persistent infections.

Mathematics Provides a Shortcut to Timely, Cost-Effective Interventions for HIV
From Science Daily: Mathematical estimates of treatment outcomes can cut costs and provide faster delivery of preventative measures. South Africa is home to the largest HIV epidemic in the world with a total of 5.6 million people living with HIV. Large-scale clinical trials evaluating combination methods of prevention and treatment are often prohibitively expensive and take years to complete. In the absence of such trials, mathematical models can help assess the effectiveness of different HIV intervention combinations, as demonstrated in a new study by Elisa Long and Robert Stavert from Yale University in the US. Their findings appear in the Journal of General Internal Medicine, published by Springer.
Scientists Pinpoint Brain's Area for Numeral Recognition
From Science Daily: Scientists at the Stanford University School of Medicine have determined the precise anatomical coordinates of a brain "hot spot," measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like "6" or "38."

Cellulose Goes Off the Rails: Without Microtubule Guidance, Cellulose Causes Changes in Organ Patterns During Growth
From Science Daily: Mathematics is everywhere in nature, and this is illustrated by the spiral patterns in plants such as pine cones, sunflowers or the arrangement of leaves around a stem. Most plants produce a new bud at 137 degrees from its predecessor, and this mathematical precision leads to observable helices. Normally, the relative position of organs does not change during growth, because the stems grow straight. But if the connection between the cytoskeleton and cellulose is removed, the cellulose fibres are synthesized in a tilted fashion and the stems start to twist. As a result, the angle between successive flowers disappears, and is instead replaced by other mathematical patterns that prove to be equally robust. Incidentally, this work suggests that in the absence of regulation, all plant stems should twist rather than grow straight.
Fermat's Last Theorem and More Can Be Proved More Simply
From Science Daily: Fermat's Last Theorem -- the idea that a certain simple equation had no solutions -- went unsolved for nearly 350 years until Oxford mathematician Andrew Wiles created a proof in 1995. Now, Case Western Reserve University's Colin McLarty has shown the theorem can be proved more simply.
Pancakes With a Side of Math: A Physiological Model for Sap Exudation in Maple Trees
From Science Daily: For many of us, maple syrup is an essential part of breakfast -- a staple accompaniment to pancakes and waffles -- but rarely do we think about the complicated and little-understood physiological aspects of syrup production. Each spring, maple growers in temperate regions around the world collect sap from sugar maple trees, which is one of the first steps in producing this delicious condiment. However, the mechanisms behind sap exudation -- processes that trigger pressure differences causing sap to flow -- in maple trees are a topic of much debate. In a paper published today in the SIAM Journal on Applied Mathematics, authors Maurizio Ceseri and John Stockie shed light on this subject by proposing a mathematical model for the essential physiological processes that drive sap flow.
What Can Sports Teams Learn from the Manufacturing Industry? Plenty
From Science Daily: What can sports teams learn from the manufacturing industry? Plenty, according to Timothy Chan of the University of Toronto (U of T) and Douglas Fearing of the Harvard Business School. Using statistics from the 2012 Major League Baseball season, Chan and Fearing found that positional flexibility -- the ability of a player to play multiple positions -- is valuable, responsible for up to 15 per cent of the team's runs, as was the case with the Chicago Cubs. Other teams like the Washington Nationals and the Tampa Bay Rays were less robust to injuries.
International Gender Difference in Math and Reading Scores Persists Regardless of Gender Equality
From Science Daily: Malala Yousafzai, the teenaged advocate for Pakistani girls' education, was released from the hospital earlier this month. Most of the world's girls don't have to fight as hard as Yousafzai for their education. However, even in countries with high gender equality, sex differences in math and reading scores persisted in the 75 nations examined by a University of Missouri and University of Leeds study. Girls consistently scored higher in reading, while boys got higher scores in math, but these gaps are linked and vary with overall social and economic conditions of the nation. A better understanding of these gaps and how they are related could help educators design curricula to help students of both genders apply their talents and deal with their weaknesses.

More Career Options May Explain Why Fewer Women Pursue Jobs in Science and Math
From Science Daily:Women may be less likely to pursue careers in science and math because they have more career choices, not because they have less ability, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. Although the gender gap in mathematics has narrowed in recent decades, with more females enrolling and performing well in math classes, females are still less likely to pursue careers in science, technology, engineering, and mathematics (STEM) than their male peers.
Prescription for Double-Dose Algebra Proves Effective
From Science Daily: Martin Gartzman sat in his dentist's waiting room last fall when he read a study in Education Next that nearly brought him to tears. A decade ago, in his former position as chief math and science officer for Chicago Public Schools, Gartzman spearheaded an attempt to decrease ninth-grade algebra failure rates, an issue he calls "an incredibly vexing problem." His idea was to provide extra time for struggling students by having them take two consecutive periods of algebra.

72% Of Professors Who Teach Online Courses Don’t Think Their Students Deserve Credit
From Tech Crunch: This is not a good sign for online education: 72 percent of professors who have taught Massive Open Online Courses (MOOCs) don’t believe that students should get official college credit, even if they did well in the class. More importantly, these are the professors who voluntarily took time to teach online courses, which means the actual number of professors who discount the quality of MOOCs is probably much (much) higher. The survey reveals the Grand Canyon-size gap between the higher-education establishment and the coalition of tech companies and lawmakers that are mandating college credit for online courses.
How Does Innovation Take Hold in a Community? Math Modeling Can Provide Clues

Species Persistence or Extinction: Through a Mathematical Lens
From Science Daily: Scientists have estimated that there are 1.7 million species of animals, plants and algae on earth, and new species continue to be discovered. Unfortunately, as new species are found, many are also disappearing, contributing to a net decrease in biodiversity. The more diversity there is in a population, the longer the ecosystem can sustain itself. Hence, biodiversity is key to ecosystem resilience. Disease, destruction of habitats, pollution, chemical and pesticide use, increased UV-B radiation, and even the presence of new species are some of the causes for disappearing species. "Allee effect," the phenomenon by which a population's growth declines at low densities, is another key reason for perishing populations, and is an overriding feature of a paper published last month in the SIAM Journal on Applied Mathematics.
The Aftermath of Calculator Use in College Classrooms
