Mathematicians have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and trade of mathematics, the researchers hope this new formulation might ultimately lead to mathematical models that better reflect the inherent uncertainties of the natural world.

A computer model that accurately predicts how composite materials behave when damaged will make it easier to design lighter, more fuel-efficient aircraft. Innovative computer codes form the basis of a computer model that shows in unprecedented detail how an aircraft's composite wing, for instance, would behave if it suffered small-scale damage, such as a bird strike.
“Seeking educational curriculum researchers. Humans need not apply.” A Washington State University professor has figured out a dramatically easier and more cost-effective way to do research on science curriculum in the classroom — and it could include playing video games. Called “computational modeling,” it involves a computer “learning” student behavior and then “thinking” as students would.
Mathematics might be able to reduce the need for invasive biopsies in patients suffering kidney damage related to the autoimmune disease lupus. Researchers have developed a math model that can predict the progression from kidney inflammation to scarring in the kidney that current treatments cannot reverse.
StarDrop 5.5 is a suite of software for guiding decisions in drug discovery, helping project teams quickly identify high-quality compounds. It works by evaluating complex data, which is often uncertain because of experimental variability or predictive error.

It includes everything from accessing, cleaning and arranging data, to intelligently trying potential inputs, preprocessing and neural network architectures, to selecting the best neural network and verifying the results.
Both whales and dolphins have pelvic (hip) bones, evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial. But new research flies directly in the face of that assumption, finding that not only do those pelvic bones serve a purpose, but their size and possibly shape are influenced by the forces of sexual selection.
A laser-based instrument being developed for the International Space Station will provide a unique 3-D view of Earth’s forests, helping to fill in missing information about their role in the carbon cycle.
The Great Pacific Garbage Patch is an area of environmental concern between Hawaii and California where the ocean surface is marred by scattered pieces of plastic. Scientists believe the garbage patch is but one of at least five, each located in the center of large, circular ocean currents called gyres that suck in and trap floating debris.
Scientists have discovered and described a new supermassive dinosaur species with the most complete skeleton ever found of its type. At 85 feet (26 m) long and weighing about 65 tons (59,300 kg) in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated.
In the unlikely event of a volcanic supereruption at Yellowstone National Park, the northern Rocky Mountains would be blanketed in meters of ash, and millimeters would be deposited as far away as New York City, Los Angeles and Miami. An improved computer model finds that the hypothetical, large eruption would create a distinctive kind of ash cloud known as an umbrella, which expands evenly in all directions.
Touchscreens and solar cells rely on special oxide layers. However, errors in the layers’ atomic structure impair not only their transparency, but also their conductivity. Using atomic models, Fraunhofer researchers have found ways of identifying and removing these errors.
Sheepdogs use just two simple rules to round up large herds of sheep, scientists have discovered. The findings could lead to the development of robots that can gather and herd livestock, crowd control techniques, or new methods to clean up the environment.
New research by University of Montana doctoral student Jared Oyler provides improved computer models for estimating temperature across mountainous landscapes. Oyler provided a new climate dataset for ecological and hydrological research and natural resource management.
All life on Earth came from one common ancestor — a single-celled organism — but what it looked like, how it lived, and how it evolved into today’s modern cells is a four-billion-year-old mystery being solved by researchers using mathematical modeling. Findings suggest for the first time that life’s Last Universal Common Ancestor (LUCA) had a ‘leaky’ membrane, which helps scientists answer two of biology’s biggest questions...
SOLIDWORKS Education Edition 2014-2015 is an integrated applications portfolio that includes tools and enhancements designed to improve teacher efficiency, shorten student design processes, increase team collaboration and enable educational productivity across numerous areas.
A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved. Almost unheard of for comet studies, the 3-D perspective provides deeper insight into which materials are shed from the nucleus of the comet and which are produced within the atmosphere, or coma.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The new technique gives scientists a way of controlling things adrift on water in a way that resembles sci-fi tractor beams.
When the space shuttle Columbia disintegrated on re-entry in 2002, sophisticated computer models were key to determining what happened. A piece of foam flew off at launch and hit a tile, damaging the leading edge of the shuttle wing and exposing the underlying structure. Temperatures soared to thousands of degrees as Columbia plunged toward Earth at 27 times the speed of sound, said Gallis, who used NASA codes and Icarus for simulations...

Simulink Real-Time enables engineers to build, test, and run real-time applications from Simulink models on dedicated target computer hardware connected to their physical systems, providing a complete end-to-end real-time simulation and testing solution.
Some 15 percent of adults suffer from fertility problems, many of these due to genetic factors. This is something of a paradox: We might expect such genes, which reduce an individual's ability to reproduce, to disappear from the population. Recent research may have solved the riddle. Not only can it explain the high rates of male fertility problems, it may open new avenues in understanding the causes of genetic diseases and their treatment.
Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well-characterized protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the team has shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.
As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, computer modeling by NASA scientists shows that friction could be the key to survival for some distant Earth-sized planets traveling in dangerous orbits. The findings are consistent with observations that Earth-sized planets appear to be very common in other star systems.
The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.
