Climate friendly fuel cells for hydrogen cars have come one step closer

Posted: 21 Jul 2013 01:17 PM PDT

Climate friendly fuel cells for hydrogen cars have come one step closer. Researchers have shown how to build fuel cells that produce as much electricity as current models, but require markedly less of the rare and valuable precious metal platinum.

Current efforts will not save the world's most endangered cat

Posted: 21 Jul 2013 01:17 PM PDT

Almost 100 million euros has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild. But the charismatic species is likely to go extinct within 50 years because the current management plans do not account for the effects of climate change. If they did, the population might increase instead concludes a new international study. The study highlights the importance of integrating climate models in management plans for biodiversity.

Helping robots become more touchy-feely, literally: Paper-thin e-skin responds to touch by lighting up

Posted: 21 Jul 2013 01:17 PM PDT

Engineers have created a new e-skin that responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits. The material is the first sensor network on flexible plastic that is user-interactive.

Making big 'Schroedinger cats': Quantum research pushes boundary by testing micro theory for macro objects

Posted: 21 Jul 2013 01:17 PM PDT

Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time.

Ancient ice melt unearthed in Antarctic mud: 20 meter sea level rise, five million years ago

Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 meters, scientists report.

Sex chromosome shocker: The 'female' X a key contributor to sperm production

Posted: 21 Jul 2013 01:13 PM PDT

Painstaking new analysis of the genetic sequence of the X chromosome -— long perceived as the "female" counterpart to the male-associated Y chromosome -— reveals that large portions of the X have evolved to play a specialized role in sperm production.
