Symmetry is ubiquitous in the natural world. It occurs in gemstones and snowflakes and even in biology, an area typically associated with complexity and diversity. There are striking examples: the shapes of virus particles, such as those causing the common cold, are highly symmetrical and look like tiny footballs.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/ChovUhkuMdw" height="1" width="1"/>Thu, 10 Apr 2014 12:22:16 EDThttp://www.sciencedaily.com/releases/2014/04/140410122216.htmhttp://www.sciencedaily.com/releases/2014/04/140410122216.htmShould you trust your financial advisor? Pseudo-mathematics and financial charlatanism
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/lhXigx1sG68/140410103005.htm
Your financial advisor calls you up to suggest a new investment scheme. Drawing on 20 years of data, he has set his computer to work on this question: If you had invested according to this scheme in the past, which portfolio would have been the best? His computer assembled thousands of such simulated portfolios and calculated for each one an industry-standard measure of return on risk. Out of this gargantuan calculation, your advisor has chosen the optimal portfolio. After briefly reminding you of the oft-repeated slogan that "past performance is not an indicator of future results," the advisor enthusiastically recommends the portfolio, noting that it is based on sound mathematical methods. Should you invest?<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/lhXigx1sG68" height="1" width="1"/>Thu, 10 Apr 2014 10:30:05 EDThttp://www.sciencedaily.com/releases/2014/04/140410103005.htmhttp://www.sciencedaily.com/releases/2014/04/140410103005.htmTechnical tests of biodiversity: When physicists play with genetics of populations
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/HLs79WDnkeM/140409093943.htm
The effect of migration on biodiversity (intended as the coexistence of different genetic traits) is an open question: does migration increase or decrease the genetic variability of populations? Or is the relationship more complex than that? A team of physicists has developed and analyzed a model that simulates the effect of migration on the genetic biodiversity of populations, and discovered that the effect is all but trivial.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/HLs79WDnkeM" height="1" width="1"/>Wed, 09 Apr 2014 09:39:43 EDThttp://www.sciencedaily.com/releases/2014/04/140409093943.htmhttp://www.sciencedaily.com/releases/2014/04/140409093943.htmMethod offers potential for understanding anti-bacterial resistance

http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/aAcigoDtqWE/140401112121.htm
A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for a particular problem can rarely be defined with certainty. The most we can do to mitigate error is to quantify the uncertainty in the model. Scientists have now offered a method to incorporate judgments into a model about structural uncertainty that results from building an 'incorrect' model.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/aAcigoDtqWE" height="1" width="1"/>Tue, 01 Apr 2014 11:21:21 EDThttp://www.sciencedaily.com/releases/2014/04/140401112121.htmhttp://www.sciencedaily.com/releases/2014/04/140401112121.htmMathematician releases 2014 Major League Baseball projections

A mathematical model can predict with more than 90 percent accuracy the blood glucose levels of individuals with type 1 diabetes up to 30 minutes in advance of imminent changes in their levels -- plenty of time to take preventative action. A person's blood glucose levels fluctuate in response to his or her insulin dose, meal intake, physical activity and emotional state. How great these fluctuations are depends on the individual, explain the researchers.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/6Xhgna-W0SA" height="1" width="1"/>Tue, 25 Mar 2014 16:44:43 EDThttp://www.sciencedaily.com/releases/2014/03/140325164443.htmhttp://www.sciencedaily.com/releases/2014/03/140325164443.htmStrange materials cropping up in condensed matter laboratories

There are many types of neurons, defined largely by the patterns of genes they use, and they 'live' in distinct brain regions. But researchers do not yet have a comprehensive understanding of these neuronal types and how they are distributed in the brain.

A new study of math anxiety shows how some people may be at greater risk to fear math not only because of negative experiences, but also because of genetic risks related to both general anxiety and math skills. The results don't mean that math anxiety can be blamed solely or even mostly on genetic factors, the researchers emphasized. In this study, genetic factors explained about 40 percent of the individual differences in math anxiety.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/PWmcqpXisSU" height="1" width="1"/>Mon, 17 Mar 2014 09:58:43 EDThttp://www.sciencedaily.com/releases/2014/03/140317095843.htmhttp://www.sciencedaily.com/releases/2014/03/140317095843.htmEquation to describe competition between genes

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.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/kxD7khBWS3U" height="1" width="1"/>Thu, 13 Mar 2014 13:43:54 EDThttp://www.sciencedaily.com/releases/2014/03/140313134354.htmhttp://www.sciencedaily.com/releases/2014/03/140313134354.htmCancer cells don't take 'drunken' walks through body
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/vwTnJqiRDEc/140311123820.htm
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.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/vwTnJqiRDEc" height="1" width="1"/>Tue, 11 Mar 2014 12:38:20 EDThttp://www.sciencedaily.com/releases/2014/03/140311123820.htmhttp://www.sciencedaily.com/releases/2014/03/140311123820.htmScientist uses physics (again) to fight cancer

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.

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.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/vMdU-cX62m8" height="1" width="1"/>Tue, 18 Feb 2014 11:09:42 ESThttp://www.sciencedaily.com/releases/2014/02/140218110942.htmhttp://www.sciencedaily.com/releases/2014/02/140218110942.htmHow evolution shapes the geometries of life

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. The team shows that Kleiber's Law captures the physics and mathematics underlying the evolution of plants' and animals' different, but equally efficient forms.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/iA1jf17zg24" height="1" width="1"/>Mon, 17 Feb 2014 16:11:06 ESThttp://www.sciencedaily.com/releases/2014/02/140217161106.htmhttp://www.sciencedaily.com/releases/2014/02/140217161106.htmGeophysicist teams with mathematicians to describe how river rocks round
http://feeds.sciencedaily.com/~r/sciencedaily/computers_math/mathematics/~3/172EnJyjUV4/140212183715.htm
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.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/172EnJyjUV4" height="1" width="1"/>Wed, 12 Feb 2014 18:37:15 ESThttp://www.sciencedaily.com/releases/2014/02/140212183715.htmhttp://www.sciencedaily.com/releases/2014/02/140212183715.htmMathematical beauty activates same brain region as great art or music

The heroes and villains in animated films tend to be on opposite ends of the moral spectrum. But they're often similar in their hair, which is usually extremely rigid or -- if it moves at all -- is straight and swings to and fro. It's rare to see an animated character with bouncy, curly hair, since computer animators don't have a simple mathematical means for describing it.
