| Monarch butterflies down again this year as decline continues Posted: 21 Mar 2012 02:22 PM PDT Unlike their colorful wings, the future of monarch butterflies may not be too bright and their numbers are expected to be alarmingly down again this year, says a researcher. |
| Holding a gun makes you think others are too, new research shows Posted: 21 Mar 2012 12:26 PM PDT Wielding a gun increases a person's bias to see guns in the hands of others, new research shows. |
| Inhibitor causing male pattern baldness and target for hair-loss treatments identified Posted: 21 Mar 2012 11:30 AM PDT Researchers have identified an abnormal amount a protein called Prostaglandin D2 in the bald scalp of men with male pattern baldness, a discovery that may lead directly to new treatments for the most common cause of hair loss in men. |
| Differences in brain function for children with math anxiety Posted: 21 Mar 2012 10:21 AM PDT Scientists have shown for the first time how brain function differs in people who have math anxiety from those who don't. A series of scans conducted while second- and third-grade students did addition and subtraction revealed that those who feel panicky about doing math had increased activity in brain regions associated with fear, which caused decreased activity in parts of the brain involved in problem-solving. |
| Posted: 21 Mar 2012 10:21 AM PDT Scientists have shown that a key protein involved in cell function and regulation is stopped by a substance present in cigarette smoke. The authors found a cancer-causing agent called reactive oxygen species present in the gaseous phase of cigarette smoke that has the ability to inhibit normal cell function. Exposure to secondhand smoke impaired the function of the sodium pump, necessary for healthy cell regulation. |
| How the smell of food affects how much you eat Posted: 21 Mar 2012 06:41 AM PDT Bite size depends on the familiarly and texture of food. Smaller bite sizes are taken for foods which need more chewing and smaller bite sizes are often linked to a sensation of feeling fuller sooner. New research shows that strong aromas lead to smaller bite sizes and suggests that aroma may be used as a means to control portion size. |
