Heat-conducting plastic: 10 times better than conventional counterparts Posted: 26 Nov 2014 02:16 PM PST The spaghetti-like internal structure of most plastics makes it hard for them to cast away heat, but a research team has made a plastic blend that does so 10 times better than its conventional counterparts.

Experimental Ebola vaccine appears safe, prompts immune response Posted: 26 Nov 2014 02:14 PM PST An experimental vaccine to prevent Ebola virus disease was well-tolerated and produced immune system responses in all 20 healthy adults who received it in a Phase 1 clinical trial.

DNA survives critical entry into Earth's atmosphere Posted: 26 Nov 2014 11:41 AM PST The genetic material DNA can survive a flight through space and re-entry into Earth's atmosphere -- and still pass on genetic information. Scientists obtained these astonishing results during an experiment on the TEXUS-49 research rocket mission.

Invisible shield found thousands of miles above Earth blocks 'killer electrons' Posted: 26 Nov 2014 10:38 AM PST An invisible shield has been discovered some 7,200 miles above Earth that blocks so-called 'killer electrons,' which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms.

High-tech mirror beams heat away from buildings into space Posted: 26 Nov 2014 10:38 AM PST Engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation.

'Eye of Sauron' provides new way of measuring distances to galaxies Posted: 26 Nov 2014 10:27 AM PST Scientists have developed a new way of measuring precise distances to galaxies tens of millions of light years away, using the W. M. Keck Observatory near the summit of Mauna Kea in Hawaii. The method is similar to what land surveyors use on Earth, by measuring the physical and angular, or 'apparent', size of a standard ruler in the galaxy, to calibrate the distance from this information.

'Off switch' for pain discovered: Activating the adenosine A3 receptor subtype is key to powerful pain relief Posted: 26 Nov 2014 10:26 AM PST A way to block a pain pathway in animal models of chronic neuropathic pain has been discovered by researchers, suggesting a promising new approach to pain relief.

Shaping the future of energy storage with conductive clay Posted: 26 Nov 2014 10:26 AM PST Materials scientists have invented clay, which is both highly conductive and can easily be molded into a variety of shapes and sizes. It represents a turn away from the rather complicated and costly processing -- currently used to make materials for lithium-ion batteries and supercapacitors -- and toward one that looks a bit like rolling out cookie dough with results that are even sweeter from an energy storage standpoint.

Dogs hear our words and how we say them Posted: 26 Nov 2014 09:43 AM PST When people hear another person talking to them, they respond not only to what is being said -- those consonants and vowels strung together into words and sentences -- but also to other features of that speech -- the emotional tone and the speaker's gender, for instance. Now, a report provides some of the first evidence of how dogs also differentiate and process those various components of human speech.

Brain researchers pinpoint gateway to human memory Posted: 26 Nov 2014 08:12 AM PST An international team of researchers has successfully determined the location, where memories are generated with a level of precision never achieved before. To this end the scientists used a particularly accurate type of magnetic resonance imaging technology.

New evidence of ancient rock art across Southeast Asia Posted: 26 Nov 2014 06:42 AM PST Research on the oldest surviving rock art of Southeast Asia shows the region's first people brought with them a rich art practice. These earliest people skilfully produced paintings of animals in rock shelters from southwest China to Indonesia. Besides these countries, early sites were also recorded in Thailand, Cambodia and Malaysia.

Bioengineering study finds two-cell mouse embryos already 'talking' about their future Posted: 26 Nov 2014 06:42 AM PST Bioengineers have discovered that mouse embryos are contemplating their cellular fates in the earliest stages after fertilization when the embryo has only two to four cells, a discovery that could upend the scientific consensus about when embryonic cells begin differentiating into cell types. Their research used single-cell RNA sequencing to look at every gene in the mouse genome.
