Researchers discover how to conduct first test of 'untestable' string theory
Researchers have planned how to carry out the first experimental test of string theory. String theory was originally developed to describe the fundamental particles and forces that make up our universe. The new research describes the unexpected discovery that string theory also seems to predict the behavior of entangled quantum particles. As this prediction can be tested in the laboratory, researchers can now test string theory.

New model may simplify high-dose radiosurgery planning
There is yet no straightforward way to determine the optimal dose level and treatment schedules for high-dose radiation therapies such as stereotactic radiation therapy, which is used to treat brain and lung cancer, or for high-dose brachytherapy for prostate and other cancers. Radiation oncology researchers may have solved the problem with a new mathematical model called the Generalized LQ (gLQ) Model that encompasses all dose levels and schedules.

Mathematical models for breast cancer detection with microwave tomography are cheaper and less risky, research finds
The most popular method of breast cancer detection today is X-ray mammography, which takes images of a compressed breast by low-dose ionizing radiation. However, there are several disadvantages to using X-rays for breast cancer screening, chief among them being the invasiveness of radiation and the high costs. Microwave tomography can provide a cheaper and less risky alternative to X-ray mammography, according to new research.

Math goes to the movies
Whether it's an exploding fireball in "Star Wars: Episode 3," a swirling maelstrom in "Pirates of the Caribbean: At World's End," or beguiling rats turning out gourmet food in "Ratatouille," computer-generated effects have opened a whole new world of enchantment in cinema. All such effects are ultimately grounded in mathematics, which provides a critical translation from the physical world to computer simulations.

New method for predicting and describing how materials break
a new mathematical model describes the fracture process for materials such as glass, polymers, concrete, ceramics, metals, rocks, and even certain geological fractures. The simulation model is powerful enough to predict and describe crack patterns in structures ranging in size from the microscopic to others as large as certain geological faults.

No 'simple theory of everything' inside the enigmatic E8, researcher says
The "exceptionally simple theory of everything," proposed by surfing physicist Garrett Lisi, does not hold water, according to some mathematicians. Centered on the elegant E8 structure, they use linear algebra and proving theorems to translate the physics into math, and show that Lisi's formulas don't work, while also demonstrating flaws in a class of related theories.

Computational feat speeds finding of genes to milliseconds instead of years
Like a magician who says, "Pick a card, any card," computer scientist Debashis Sahoo seemed to be offering some kind of trick when he asked researchers to pick any two genes already known to be involved in stem cell development. Finding such genes can take years and hundreds of thousands of dollars, but Sahoo was promising the skeptical stem cell scientists that, in a fraction of a second and for practically zero cost, he could find new genes involved in the same developmental pathway as the two genes provided. Sahoo went on to show that this amazing feat could actually be performed.

Mathematical model may offer better understanding of embryonic development
A mathematical model can predict complex signaling patterns that could help scientists determine how stem cells in an embryo later become specific tissues, knowledge that could be used to understand and treat developmental disorders and some diseases.

An improved method for calculating tumor growth
When treating cancer, it is an advantage to know the rate of growth of the cancer tumor. The standard method currently used to determine tumor growth, however, is erroneous, according to researchers who have developed a new model.

Leaf veins inspire a new model for distribution networks
A straight line may be the shortest path from A to B, but it's not always the most reliable or efficient way to go. In fact, depending on what's traveling where, the best route may run in circles, according to a new model that bucks decades of theorizing on the subject. A team of biophysicists have developed a mathematical model showing that complex sets of interconnecting loops -- like the netted veins that transport water in a leaf -- provide the best distribution network for supplying fluctuating loads to varying parts of the system. It also shows that such a network can best handle damage.

Physicist writes a better formula to predict baseball success
A physicist has developed a new formula to predict baseball success. The basic formula, which has been tweaked over the years, uses the number of runs scored per game (RPG) and runs given up per game to estimate a team's winning percentage.

Simple math explains dramatic beak shape variation in Darwin's finches
In a new study, researchers demonstrate that simple changes in beak length and depth can explain the important morphological diversity of all beak shapes within Darwin's famous finches. Broadly, the work suggests that a few, simple mathematical rules may be responsible for complicated biological adaptations.

Can math and science help solve crimes? Scientists work with Los Angeles police to identify and analyze crime 'hotspots'
Scientists working with the Los Angeles Police Department to analyze crime patterns report that criminal "hotspots" come in at least two different types -- one of which can be suppressed by police. They believe their findings apply to cities worldwide.

The mathematics behind a good night's sleep
A mathematics professor is using math to develop a new computer model that can be easily manipulated by other scientists and doctors to predict how different environmental, medical, or physical changes to a person's body will affect their sleep. Their model will also provide clues to the most basic dynamics of the sleep-wake cycle.

Epidemiologists explore dynamics of Mexico's H1N1 pandemic
Influenza surveillance mechanisms in Mexico were adequate during the fast-spreading H1N1 outbreak in 2009, yet Mexico did not have the infrastructure to quickly identify the emergence of this novel strain, epidemiologists.

When molecules leave tire tracks: New approach to optimizing molecular self-organization
Certain types of molecules form patterns when deposited onto substrates. Photovoltaic and sensor devices from organic compounds depend on this phenomenon of self-organization. Physicists have now developed a model that predicts these patterns and thus allows optimization of the molecular synthesis in the future.
