Lichen can survive in space: Space station research sheds light on origin of life; potential for better sunscreens (June 23, 2012) -- You can freeze it, thaw it, vacuum dry it and expose it to radiation, but still life survives. Research on the International Space Station is giving credibility to theories that life came from outer space -- as well as helping to create better sunscreens. ... > full story
Forgotten star cluster now found useful in studies of Sun and hunt for Earth-like planets (June 23, 2012) -- A loose group of stars, known for over 180 years but never before studied in detail, has been revealed to be an important new tool in the quest to understand the evolution of stars like the Sun, and in the search for planets like Earth. The star cluster holds great promise for use as a standard gauge in fundamental stellar astrophysics. ... > full story
New technique allows simulation of noncrystalline materials (June 23, 2012) -- Scientists have found a new mathematical approach to simulating the electronic behavior of noncrystalline materials, which may eventually play an important part in new devices including solar cells, organic LED lights and printable, flexible electronic circuits. ... > full story
Reward the second best, ignore the best (June 22, 2012) -- New research suggests reasons why the richest should pay more tax; why rewarding the top performers leads to recurrent crises and scandals; and why we should resist the temptation to learn from and imitate the most successful. ... > full story
Proximity of new planets stuns even astronomers (June 21, 2012) -- One is a rocky planet 1.5 times the size of Earth. The other is a gaseous world nearly four times Earth's size. Together they form a spectacular system in which two planets orbit closer to each other than any yet discovered. ... > full story
Study of phase change materials could lead to better computer memory (June 21, 2012) -- Memory devices for computers require a large collection of components that can switch between two states, which represent the ones and zeros of binary language. Engineers hope to make next-generation chips with materials that distinguish between these states by physically rearranging their atoms into different phases. Researchers have now provided new insight into how this phase change happens, which could help engineers make memory storage devices faster and more efficient. ... > full story
Researchers tune the strain in graphene drumheads to create quantum dots (June 21, 2012) -- Researchers have shown that they can tune the strain in graphene suspended like drumheads over microscopic holes in a substrate of silicon oxide using the tip of an advanced scanning probe microscope and a conducting plate below the substrate. Tuning the strain enabled the group to create areas in the graphene where electrons behaved as though they were confined to quantum dots. ... > full story
Could Mars have sustained life? Extensive water in Mars' interior (June 21, 2012) -- Until now, Earth was the only planet known to have vast reservoirs of water in its interior. Scientists analyzed the water content of two Martian meteorites and found that the amount of water in places of the Martian mantle is vastly larger than previous estimates and is similar to that of Earth's. The results affect our understanding about Martian geologic history, how water got to the Martian surface, and whether Mars could have sustained life. ... > full story
Lab-engineered kidney project reaches early milestone (June 21, 2012) -- Regenerative medicine researchers at Wake Forest Baptist Medical Center have reached an early milestone in a long-term project that aims to build replacement kidneys in the lab to help solve the shortage of donor organs. ... > full story
Nano-infused paint can detect strain (June 21, 2012) -- Nanotube-infused paint can reveal strain in materials by its fluorescence. The material holds promise for detecting strain in aircraft, bridges and buildings. ... > full story
Graphene Research: Trapping light in a carbon net (June 21, 2012) -- Graphene, an ordered monolayer of carbon, is the thinnest substance known, and yet has extraordinary mechanical strength. A new study shows that its two-dimensional network of atoms can even trap light. ... > full story
Microelectronics: Two at a time (June 21, 2012) -- A new design reduces the areal footprint of nanowire transistors by a factor of two. Scientists have now integrated two transistors onto a single vertical silicon nanowire, pushing the areal density limit of nanowire transistors even further. ... > full story
