| Human cells respond in healthy, unhealthy ways to different kinds of happiness Posted: 29 Jul 2013 01:19 PM PDT Human bodies recognize at the molecular level that not all happiness is created equal, responding in ways that can help or hinder physical health, according to new research.  |
| Posted: 29 Jul 2013 01:17 PM PDT Some social amoebae farm the bacteria they eat. Now scientists have taken a closer look at one lineage, or clone, of D. discoideum farmer. This farmer carries not one but two strains of bacteria. One strain is the "seed corn" for a crop of edible bacteria, and the other strain is a weapon that produces defensive chemicals. The edible bacteria, the scientists found, evolved from the toxic one.  |
| Evolution of monogamy in humans the result of infanticide risk, new study suggests Posted: 29 Jul 2013 01:15 PM PDT The threat of infants being killed by unrelated males is the key driver of monogamy in humans and other primates, a new study suggests.  |
| Mini-monsters of the forest floor Posted: 29 Jul 2013 01:15 PM PDT A biologist has identified 33 new species of predatory ants in Central America and the Caribbean, and named about a third of the tiny but monstrous-looking insects after ancient Mayan lords and demons.  |
| Make it yourself with a 3-D printer and save big time Posted: 29 Jul 2013 11:46 AM PDT A new study shows that families can save hundreds if not thousands of dollars by making their own household items with a 3-D printer.  |
| Therapeutic fecal transplant: Hope for cure of childhood diarrhea comes straight from the gut Posted: 29 Jul 2013 10:30 AM PDT Call it therapeutic poop, if you will, but the best hope yet for an effective treatment of childhood infections with the drug-resistant bacterium C. difficile may come straight from the gut, according to recent research. This is why pediatric gastroenterologists are launching a fecal transplantation program for patients with recurrent diarrhea caused by what they say is a wily pathogen that is increasingly impervious to drugs and a rapidly growing problem among children and adults.  |
| When fluid dynamics mimic quantum mechanics Posted: 29 Jul 2013 08:19 AM PDT Researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle duality.  |
| Borneo's orangutans are coming down from the trees; Behavior may show adaptation to habitat change Posted: 29 Jul 2013 05:33 AM PDT Orangutans might be the king of the swingers, but primatologists in Borneo have found that the great apes spend a surprising amount of time walking on the ground. The research found that it is common for orangutans to come down from the trees to forage or to travel, a discovery which may have implications for conservation efforts.  |
| Cement converted into an electrical conductor Posted: 29 Jul 2013 05:32 AM PDT Researchers have developed a cementitious material incorporating carbon nanofibers in its composition, turning cement into an excellent conductor of electricity capable of performing functions beyond its usual structural function.  |
