| Posted: 19 Nov 2014 10:27 AM PST Scientists have completed an exhaustive description of the mouse's functional genome elements and their comparison with the human genome. Comparing humans and mice enables us to better understand mammalian biology and evolution, as well as contributing new information on the use of mice as animal models for looking at human disease. |
| Posted: 19 Nov 2014 09:51 AM PST Researchers studying the roots of depression have developed a test to measure analytical thinking and rumination, that are hallmarks of the condition, leading them closer to the idea that depression may actually be an adaptation meant to help people cope with complex problems such as chronic illnesses or marriage breakups. |
| Biochemists build largest synthetic molecular 'cage' ever Posted: 19 Nov 2014 07:20 AM PST Biochemists have created the largest protein ever that self-assembles into a molecular cage. Their designed protein, which does not exist in nature, is hundreds of times smaller than a human cell. The research could lead to 'synthetic vaccines' that protect people from the flu, HIV and perhaps other diseases. It could also lead to new methods of delivering pharmaceuticals inside of cells and the creation of new nano-scale materials. |
| Improving memory by suppressing a molecule that links aging to Alzheimer's disease Posted: 19 Nov 2014 07:18 AM PST Researchers find a way to improve memory by suppressing a molecule that links aging to Alzheimer's disease. |
| Police face higher risk of sudden cardiac death during stressful duties Posted: 19 Nov 2014 05:52 AM PST Police officers in the United States face roughly 30 to 70 times higher risk of sudden cardiac death when they're involved in stressful situations -- suspect restraints, altercations, or chases -- than when they're involved in routine or non-emergency activities. |
| Scientists prevent memory problems caused by sleep deprivation Posted: 18 Nov 2014 03:24 PM PST Scientists have found that a particular set of cells in a small region of the brain are responsible for memory problems after sleep loss. By selectively increasing levels of a signaling molecule in these cells, the researchers prevented mice from having memory deficits. |
| Taking antibiotics during pregnancy increases risk for child becoming obese Posted: 18 Nov 2014 11:18 AM PST A study just released by Columbia University's Mailman School of Public Health found that children who were exposed to antibiotics in the second or third trimester of pregnancy had a higher risk of childhood obesity at age 7. The research also showed that for mothers who delivered their babies by a cesarean section, whether elective or non-elective, there was a higher risk for obesity in their offspring. |
| Car crash survival rates increase with being younger, male and driving a big vehicle Posted: 18 Nov 2014 09:55 AM PST Vehicle inequities have a significant impact on survivability in head-on collisions, a study by a doctoral student in epidemiology shows. Motor vehicle crashes are the most common cause of unintentional life lost around the world, with about 30,000 deaths occurring annually in the U.S. due to motor-vehicle crashes. |
| Facebook games may actually do some good in your life Posted: 18 Nov 2014 09:55 AM PST Beyond being a fun distraction, social network games can offer family members a meaningful way to interact and meet social obligations, a new study concludes. Researchers found that some online games offer families a common topic of conversation and enhance the quality of time spent together, despite the fact that most don't necessarily involve any direct communication. The games can also bring together family members who may be only distantly connected, with respondents citing experiences such as connecting with long-lost cousins or bolstering relationships with aging aunts. |
| Shift in gut bacteria observed in fiber supplement study may offer good news for weight loss Posted: 18 Nov 2014 09:55 AM PST Most Americans don't get the daily recommended amount of fiber in their diet, though research has shown that dietary fiber can cause a shift in the gut toward beneficial bacteria, reducing the risk of colon cancer, type 2 diabetes, and other diseases. A new study shows that two specific functional fibers may also have the potential to assist in weight loss when made part of a long-term, daily diet. |
