Gifted men and women define success differently, 40-year study finds

From

*Science Daily*: Researchers spent four decades studying a group of mathematically talented adolescents, finding that by mid-life they were extraordinarily accomplished and enjoyed a high level of life satisfaction. Gender, however, played a significant role in how they pursued - and defined - career, family and success. Intellectually gifted women tracked for 40 years were found to earn less money, be less present in STEM fields, and work fewer hours than their male counterparts. Despite that, they expressed a high level of personal satisfaction and sense of achievement, defining success more broadly than men to include family and community service. These observations come from the most recent round of results from the Study of Mathematically Precocious Youth (SMPY), the largest longitudinal research project of its kind. The results were posted this week to Psychological Science.

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.

Mechanical ventilation a key indicator for pre-term children's maths problems

From

*Science Daily*: Both the length of time spent in hospital after birth and the use of mechanical ventilation are key indicators of reduced mathematical ability in preterm children, researchers report.

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.

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.

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.

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.
