| Posted: 02 Oct 2014 11:18 AM PDT By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, 'perfect fluid' that give clues to the state of the young universe just microseconds after the Big Bang.  |
| Previously unseen details of seafloor exposed in new map Posted: 02 Oct 2014 11:18 AM PDT A new map of the world's seafloor has been created. Twice as accurate as the previous version, the new map features a much more vivid picture of seafloor structures, including thousands of previously uncharted mountains.  |
| Swirling cloud at Titan's pole is cold and toxic Posted: 01 Oct 2014 11:00 AM PDT Scientists analyzing data from NASA's Cassini mission have discovered that a giant, toxic cloud is hovering over the south pole of Saturn's largest moon, Titan, after the atmosphere there cooled dramatically. The scientists found that this giant polar vortex contains frozen particles of the toxic compound hydrogen cyanide, or HCN.  |
| Gut bacteria are protected by host during illness Posted: 01 Oct 2014 10:34 AM PDT To protect their gut microbes during illness, sick mice produce specialized sugars in the gut that feed their microbiota and maintain a healthy microbial balance. This protective mechanism also appears to help resist or tolerate additional harmful pathogens, and its disruption may play a role in human diseases such as Crohn's disease.  |
| Nature collides with James Bond: Newly discovered ant species hides in plain sight Posted: 01 Oct 2014 07:26 AM PDT A new species of ant has been discovered that uses social parasitism to access host ant species' food sources and foraging trails: Cephalotes specularis, commonly known as the mirror turtle ant. Mirror turtle ants are the first-known ant species to use visual mimicry to parasitize another ant species. They have mastered the movements of C. ampla and are careful to dodge the host ants to avoid them detecting C. specularis' scent. By mimicking C. ampla, the mirror turtle ants can access their food and follow their foraging trails to food sources. In spy terms, this new form of social parasitism allows ants to steal food from an enemy.  |
| Lift weights, improve your memory, study shows Posted: 01 Oct 2014 07:20 AM PDT Here's another reason why it's a good idea to hit the gym: it can improve memory. A new study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.  |
