Immune cells to be tested on the International Space Station

Posted: 19 Apr 2014 06:00 AM PDT

The human body is fine-tuned to Earth's gravity. Scientists are now conducting an experiment on the International Space Station (ISS) to study whether this also applies to human cells. We know the effect of gravity on muscles, bones and joints inside out; it has been studied extensively in medicine for centuries. For a long time, however, exactly how gravity affects the cells remained a mystery.

ADHD: Scientists discover brain's anti-distraction system

Posted: 18 Apr 2014 11:12 AM PDT

Psychologists have made a brain-related discovery that could revolutionize doctors' perception and treatment of attention-deficit disorders. This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction.

Mom's diet mirrors child's food allergies

'Dressed' laser aimed at clouds may be key to inducing rain, lightning

Posted: 18 Apr 2014 11:12 AM PDT

The adage "Everyone complains about the weather but nobody does anything about it" may one day be obsolete if researchers further develop a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning. Other possible uses of this technique could be used in long-distance sensors and spectrometers to identify chemical makeup.

Plants with dormant seeds give rise to more species

Posted: 18 Apr 2014 11:12 AM PDT

Seeds that sprout as soon as they're planted may be good news for a garden. But in the wild, a plant whose seeds sprouted at the first warm spell or rainy day would risk disaster. More than just an insurance policy against late frosts or unexpected dry spells, it turns out that seed dormancy has long-term advantages too: plants whose seeds put off sprouting until conditions are more certain give rise to more species.

'Exotic' material is like a switch when super thin

Posted: 18 Apr 2014 11:11 AM PDT

Researchers have shown how to switch a particular transition metal oxide, a lanthanum nickelate, from a metal to an insulator by making the material less than a nanometer thick. Ever-shrinking electronic devices could get down to atomic dimensions with the help of transition metal oxides, a class of materials that seems to have it all: superconductivity, magnetoresistance and other exotic properties. These possibilities have scientists excited to understand everything about these materials, and to find new ways to control their properties at the most fundamental levels.

Gecko-like adhesives now useful for real world surfaces

Posted: 18 Apr 2014 11:11 AM PDT

The ability to stick objects to a wide range of surfaces such as drywall, wood, metal and glass with a single adhesive has been the elusive goal of many research teams across the world, but now a team inventors describe a new, more versatile version of their invention, Geckskin, that can adhere strongly to a wider range of surfaces, yet releases easily, like a gecko's feet.

Impact glass from asteroids and comets stores biodata for millions of years

Posted: 18 Apr 2014 11:11 AM PDT

Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds.

Impurity size affects performance of emerging superconductive material

Posted: 18 Apr 2014 11:11 AM PDT

Impurities can hurt performance -- or possibly provide benefits -- in a key superconductive material that is expected to find use in a host of applications, including future particle colliders. The size of the impurities determines whether they help or hinder the material's performance, according to new research.
