Solar-induced hybrid fuel cell produces electricity directly from biomass
Science Daily, February 19, 2014
Researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy.
Single chip device to provide real-time 3-D images from inside the heart, blood vessels
Science Daily, February 19, 2014
Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels.
Asian elephants reassure others in distress: First empirical evidence of consolation in elephants
Science Daily, February 19, 2014
Asian elephants console others who are in distress, using physical touches and vocalizations, new research shows. The findings are the first empirical evidence of consolation in elephants. Consolation behavior is rare in the animal kingdom, with empirical evidence previously provided only for the gr...
World''s most powerful terahertz laser chip
Science Daily, February 19, 2014
Researchers have built the world''s most powerful terahertz laser chip. The new laser chip has exceeded a 1 Watt output power from a quantum cascade terahertz laser. The new record more than doubles landmarks set last year. Terahertz waves, which lie in the part of the electromagnetic spectrum betwe...
New light shed on habitat of early apes
Science Daily, February 19, 2014
An international team of anthropologists has discovered definitive evidence of the environment inhabited by the early ape Proconsul on Rusinga Island, Kenya. The findings provide new insights into understanding and interpreting the connection between habitat preferences and the early diversification...
Bats inspire ''micro air vehicle'' designs: Small flying vehicles, complete with flapping wings, may now be designed
Science Daily, February 19, 2014
By exploring how creatures in nature are able to fly by flapping their wings, researchers hope to apply that knowledge toward designing small flying vehicles known as "micro air vehicles" with flapping wings.
Wings, tails, fins: Study looks at how animals propel themselves
Science Daily, February 19, 2014
The wonder of animal movement - from the tiniest of insects to the largest fish in the sea - has been a subject of mystery for ages. But when it comes to animal propulsion, there are almost infinite kinds, but also limits that can't be pushed or breakdowns will occur, according to an unusual study.
Artificial leaf jumps developmental hurdle
Science Daily, February 19, 2014
Scientists report advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is an important goal. Hydrogen is an important fuel in itself and serves as an indispensible reagent for th...
Interactive map of human genetic history revealed
Science Daily, February 18, 2014
A global map detailing the genetic histories of 95 different populations across the world, showing likely genetic impacts of European colonialism, the Arab slave trade, the Mongol Empire and European traders near the Silk Road mixing with people in China, has been revealed for the first time.
Discovery may help to explain mystery of ''missing'' genetic risk, susceptibility to common diseases
Science Daily, February 18, 2014
A new study could help to answer an important riddle in our understanding of genetics: why research to look for the genetic causes of common diseases has failed to explain more than a fraction of the heritable risk of developing them.
