3-D Comet Study Reveals Chemical Factory at Work

August 12, 2014 12:05 pm | by NASA | News | Comments

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 Create Water Tractor Beam

August 11, 2014 12:57 pm | by Australian National University | News | Comments

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...

Mutations from Venus, Mutations from Mars: A Sex-difference Approach to Harmful Mutation

July 28, 2014 5:36 pm | by Weizmann Institute of Science | News | Comments

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.

Computer Models Reveal Quantum Effects in Biological Oxygen Transport

July 18, 2014 3:41 pm | by Trinity College | News | Comments

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.

NASA Finds Friction from Tides Could Help Distant Earths Survive

July 15, 2014 4:28 pm | by Elizabeth Zubritsky, NASA Goddard Space Flight Center | News | Comments

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.

Chemists Discover Boron Buckyball

July 15, 2014 11:55 am | by Brown University | News | Comments

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.

Auto Industry Gets Serious about Lighter Materials

June 10, 2014 2:09 pm | by Dee-Ann Durbin, AP Auto Writer | News | Comments

While hybrids and electrics may grab the headlines, the real frontier in fuel economy is the switch to lighter materials. Automakers have been experimenting for decades with lightweighting, as the practice is known, but the effort is gaining urgency with the adoption of tougher fuel efficiency standards. To meet the U.S. government's goal of nearly doubling average fuel economy to 45 mpg by 2025, cars need to lose some serious pounds.
