| Scientists discover sleeping brain behaves as if it's remembering something Posted: 08 Oct 2012 07:04 AM PDT UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this region, called the entorhinal cortex, behaves as if it's remembering something, even during anesthesia–induced sleep — a finding that counters conventional theories about sleep-time memory consolidation. |
| Liquorice Offers Clue to Cleaner Medical Implants Posted: 08 Oct 2012 06:54 AM PDT A nanotech material containing an extract from liquorice can be used to sterilize and protect medical devices and implants which include biological components, and protects these functional bio-components during the sterilization process. |
| Researchers Develop New Way to Determine Amount of Charge Remaining in Battery Posted: 08 Oct 2012 06:49 AM PDT Researchers from North Carolina State University have developed a new technique that allows users to better determine the amount of charge remaining in a battery in real time. That’s good news for electric vehicle drivers, since it gives them a better idea of when their car may run out of juice. |
| Inheritance of mitochondrial disease determined when mother is still an embryo Posted: 08 Oct 2012 06:45 AM PDT The risk of a child to inherit mitochondrial diseases - i. e. malfunction in what is usually referred to as the power plants of the cell - is largely decided when the future mother herself is still an embryo. This according to a novel study by scientists at Karolinska Institutet and the Max Planck Institute in Germany, which is published in the journal Nature Genetics. |
| Demographic miracle in the deserts Posted: 08 Oct 2012 06:41 AM PDT Dryland ecosystems cover 41% of the Earth’s land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive impact on some plants. A study involving the Max Planck Institute for Demographic Research in Rostock has come to this conclusion. Using demographic methods, ecologist Roberto Salguero-Gómez investigates desert plants to find out how vulnerable they are to climate change. |
