| Posted: 17 Sep 2014 10:18 AM PDT Of all of the world's species, humans and chimpanzees are some of the only species to coordinate attacks on their own members. Since Jane Goodall introduced lethal inter-community killings, primatologists have debated the concept of warfare in this genus. New research from an international coalition of ape researchers has shed new light on the subject, suggesting that human encroachment and interference is not, as previous researchers have claimed, an influential predictor of chimp-on-chimp aggression.  |
| New explanation for origin of plate tectonics: What set Earth's plates in motion? Posted: 17 Sep 2014 10:18 AM PDT Geologists have a new explanation for the origin of plate tectonics. Researchers suggest it was triggered by the spreading of early continents then it eventually became a self-sustaining process.  |
| Posted: 17 Sep 2014 10:18 AM PDT Previous work suggested that Europeans descended from two ancestral groups: indigenous hunter-gatherers and early European farmers. This new study shows that there was also a third ancestral group, the Ancient North Eurasians, who contributed genetic material to almost all present-day Europeans. The research also reveals an even older lineage, the Basal Eurasians.  |
| Certain gut bacteria may induce metabolic changes following exposure to artificial sweeteners Posted: 17 Sep 2014 10:16 AM PDT Artificial sweeteners have long been promoted as diet and health aids. But breaking research shows that these products may be leading to the very diseases they were said to help prevent: scientists have discovered that, after exposure to artificial sweeteners, our gut bacteria may be triggering harmful metabolic changes.  |
| Don't underestimate your mind's eye: Objects don't need to be seen to impact decision-making Posted: 16 Sep 2014 11:28 AM PDT Objects in our visual environment needn't be seen in order to impact decision making, according to new research. Take a look around, and what do you see? Much more than you think you do, thanks to your finely tuned mind's eye, which processes images without your even knowing.  |
| NASA's Mars Curiosity rover arrives at Martian mountain Posted: 11 Sep 2014 03:30 PM PDT NASA's Mars Curiosity rover has reached the Red Planet's Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission's long-term prime destination.  |
| How salt causes buildings to crumble Posted: 11 Sep 2014 09:59 AM PDT Salt crystals are often responsible when buildings start to show signs of aging. Researchers have studied salt damage in greater depth and can now predict weathering processes more accurately.  |
| World's largest DNA origami created Posted: 11 Sep 2014 06:47 AM PDT Researchers have created the world's largest DNA origami, which are nanoscale constructions with applications ranging from biomedical research to nanoelectronics. DNA origami are self-assembling biochemical structures that are made up of two types of DNA.  |
