| Finding turns neuroanatomy on its head: Researchers present new view of myelin Posted: 18 Apr 2014 01:14 PM PDT Neuroscientists have made a discovery that turns 160 years of neuroanatomy on its head. Myelin, the electrical insulating material long known to be essential for the fast transmission of impulses along the axons of nerve cells, is not as ubiquitous as thought, according to a new work. "The fact that it is the most evolved neurons, the ones that have expanded dramatically in humans, suggests that what we're seeing might be the "future." As neuronal diversity increases and the brain needs to process more and more complex information, neurons change the way they use myelin to "achieve" more," says the main researcher.  |
| Posted: 17 Apr 2014 09:45 AM PDT One strategy for addressing the world's energy crisis is to stop wasting so much energy when producing and using it, such as in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices, with potentially enormous energy savings.  |
| New city wall discovered at ancient Roman port Posted: 17 Apr 2014 06:05 AM PDT Researchers have discovered a new section of the boundary wall of the ancient Roman port of Ostia, proving the city was much larger than previously estimated.  |
| Targeting cancer with a triple threat: New nanoparticles can deliver three drugs at once Posted: 15 Apr 2014 09:55 AM PDT Chemists have designed nanoparticles that can deliver three cancer drugs at a time. Such particles could be designed to carry even more drugs, allowing researchers to develop new treatment regimens that could better kill cancer cells while avoiding the side effects of traditional chemotherapy. "We think it's the first example of a nanoparticle that carries a precise ratio of three drugs and can release those drugs in response to three distinct triggering mechanisms," says the lead researcher and author.  |
| Lashing out at your spouse? Check your blood sugar Posted: 14 Apr 2014 12:44 PM PDT Lower levels of blood sugar may make married people angrier at their spouses and even more likely to lash out aggressively, new research reveals. Researchers found that levels of blood glucose in married people, measured each night, predicted how angry they would be with their spouse that evening.  |
