NASA's Curiosity rover finds fresh signs of ingredients for life on Mars
Mars's life-friendly past just got friendlier. Using samples previously collected by the NASA rover Curiosity, scientists have discovered evidence of nitrates in Martian rock: nitrogen compounds that on Earth ...
Artificially intelligent robot scientist 'Eve' could boost search for new drugs
Eve, an artificially-intelligent 'robot scientist' could make drug discovery faster and much cheaper, say researchers writing in the Royal Society journal Interface. The team has demonstrated the success of the ...
Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria
Wriggle your toes in a marsh's mucky bottom sediment and you'll probably inhale a rotten egg smell, the distinctive odor of hydrogen sulfide gas. That's the biochemical signature of sulfur-using bacteria, ...
Tarantula toxin is used to report on electrical activity in live cells
Crucial experiments to develop a novel probe of cellular electrical activity were conducted in the Neurobiology course at the Marine Biological Laboratory (MBL) in 2013. Today, that optical probe, which combines ...
Enabling bendable optoelectronics devices: Gallium nitride micro-rods grown on graphene substrates

Impact glass stores biodata for millions of years
(Phys.org) —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 ...
Building new drugs just got easier
Scientists at The Scripps Research Institute (TSRI) have developed a method for modifying organic molecules that significantly expands the possibilities for developing new pharmaceuticals and improving old ones.
Breakthrough finds molecules that block previously 'undruggable' protein tied to cancer
A team of scientists at the University of Kansas has pinpointed six chemical compounds that thwart HuR, an "oncoprotein" that binds to RNA and promotes tumor growth.
Accelerating materials discovery with world's largest database of elastic properties
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have published the world's largest set of data on the complete elastic properties of inorganic compounds, increasing ...
Climate change, plant roots may accelerate carbon loss from soils (Update)
Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought, according to Oregon State University soil scientists.
Researchers find patterns in evolving genomes of thousands of species
A pair of genetics researchers at Iowa State University found striking patterns in the building blocks of DNA in a wide variety of species, according to their recently published paper.
Scientists identify mineral that destroys organic compounds, with implications for Mars Curiosity mission
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, with implications for Mars research.
Potential new breathalyzer for lung cancer screening
Researchers from Chongqing University in China have developed a high sensitive fluorescence-based sensor device that can rapidly identify cancer related volatile organic compounds—biomarkers found exclusively in the exhaled ...
