| Researchers optically levitate a glowing, nanoscale diamond Posted: 12 Aug 2013 05:25 PM PDT Researchers have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. |
| Brain's flexible hub network helps humans adapt Posted: 12 Aug 2013 02:04 PM PDT New research offers compelling evidence that a well-connected core brain network based in the lateral prefrontal cortex and the posterior parietal cortex -- parts of the brain most changed evolutionarily since our common ancestor with chimpanzees -- contains "flexible hubs" that coordinate the brain's responses to novel cognitive challenges. |
| Inducing and augmenting labor may be associated with increased risk of autism Posted: 12 Aug 2013 01:59 PM PDT Pregnant women whose labors are induced or augmented may have an increased risk of bearing children with autism, especially if the baby is male, according to a large, retrospective analysis. |
| Neandertals made the first specialized bone tools in Europe Posted: 12 Aug 2013 12:42 PM PDT Modern humans replaced Neandertals in Europe about 40,000 years ago, but the Neandertals' capabilities are still greatly debated. Some argue that before they were replaced, Neandertals had cultural capabilities similar to modern humans, while others argue that these similarities only appear once modern humans came into contact with Neandertals. |
| Electrical signatures of consciousness in the dying brain Posted: 12 Aug 2013 12:35 PM PDT About 20 percent of cardiac arrest survivors report having a near death experience with visions and perceptions, but are the experiences real? A new study suggests the dying brain is capable of well-organized electrical activity during the early stages of clinical death. The study provides the first scientific framework for the near-death experience. |
| Posted: 12 Aug 2013 09:13 AM PDT Researchers have decoded a previously unknown molecular mechanism in the fertilization process of vertebrates. The team of scientists have identified a specific protein in frog egg extracts that the male basal bodies need, but that is produced only by the reproductive cells of the female. This "teamwork" between the egg and sperm is what makes embryo development possible. |
| Scientists have found new evidence to show how early humans migrated into Europe Posted: 12 Aug 2013 07:27 AM PDT Humans originated in Africa. But what route did they take as they began to disperse around the world 60,000 years ago? A professor has played a key role in finding the answer to one of the most fundamental questions in the history of humankind. |
| Cosmology in the lab using laser-cooled ions Posted: 12 Aug 2013 07:25 AM PDT Scientists would love to know which forces created our universe some 14 billion years ago. How could -- due to a breaking of symmetry -- matter, and thus stars and galaxies, be created from an originally symmetrical universe in which the same conditions prevailed everywhere shortly after the Big Bang? Now, the Big Bang is an experiment that cannot be repeated. But the principle of symmetry and its disturbance can definitely be investigated under controlled laboratory conditions. |
