| Posted: 30 Oct 2014 07:16 AM PDT Academics are challenging the foundations of quantum science with a radical new theory on parallel universes. Scientists now propose that parallel universes really exist, and that they interact. They show that such an interaction could explain everything that is bizarre about quantum mechanics.  |
| Seeing dinosaur feathers in a new light Posted: 30 Oct 2014 07:07 AM PDT Why were dinosaurs covered in a cloak of feathers long before the early bird species Archaeopteryx first attempted flight? Researchers postulate that these ancient reptiles had a highly developed ability to discern color. Their hypothesis: The evolution of feathers made dinosaurs more colorful, which in turn had a profoundly positive impact on communication, the selection of mates and on dinosaurs' procreation.  |
| Scientists generate first human stomach tissue in lab with stem cells Posted: 29 Oct 2014 11:56 AM PDT Scientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory -- creating an unprecedented tool for researching the development and diseases of an organ central to several public health crises, ranging from cancer to diabetes. Scientists used human pluripotent stem cells -- which can become any cell type in the body -- to grow a miniature version of the stomach.  |
| Dozens of genes associated with autism in new research Posted: 29 Oct 2014 11:12 AM PDT Two major genetic studies of autism, involving more than 50 laboratories worldwide, have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms that govern whether, when, and how genes are activated overall.  |
| Planet-forming lifeline discovered in a binary star system Posted: 29 Oct 2014 11:12 AM PDT Scientists have detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disk of planet-forming material that otherwise would have disappeared long ago.  |
| Scientists make enzyme that could help explain origins of life Posted: 29 Oct 2014 11:12 AM PDT Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.  |
| Posted: 29 Oct 2014 10:34 AM PDT Many factors, both genetic and environmental, have been blamed for increasing the risk of a diagnosis of schizophrenia. Some, such as a family history of schizophrenia, are widely accepted. Others, such as infection with Toxoplasma gondii, a parasite transmitted by soil, undercooked meat and cat feces, are still viewed with skepticism. A new study used epidemiological modeling methods to determine the proportion of schizophrenia cases that may be attributable to T. gondii infection. The work suggests that about one-fifth of cases may involve the parasite.  |
| Posted: 29 Oct 2014 10:34 AM PDT Researchers have described a new system that integrates a laser-ablation propulsion system with the gas blasting nozzles of a spacecraft which can increase the speed of the gas flow out of the system to supersonic speeds while reducing the amount of burned fuel.  |
| Heavy drinking in adolescence associated with lasting brain changes, animal study suggests Posted: 28 Oct 2014 06:41 PM PDT Heavy drinking during adolescence may lead to structural changes in the brain and memory deficits that persist into adulthood, according to an animal study. The study found that, even as adults, rats given daily access to alcohol during adolescence had reduced levels of myelin -- the fatty coating on nerve fibers that accelerates the transmission of electrical signals between neurons.  |
| High milk intake linked with higher fractures and mortality, research suggests Posted: 28 Oct 2014 06:40 PM PDT A high milk intake in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death, suggests observational research. Women who drank more than three glasses of milk a day had a higher risk of death than women who drank less than one glass of milk a day.  |
| Giant tortoises gain a foothold on a Galapagos island Posted: 28 Oct 2014 11:54 AM PDT A population of endangered giant tortoises has recovered on the Galapagos island of Española, a finding described as "a true story of success and hope in conservation."  |
| New evidence for an exotic, predicted superconducting state Posted: 26 Oct 2014 04:53 PM PDT Physicist have produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can arise when a superconductor is exposed to a strong magnetic field.  |
