| 'Rare' genetic variants are surprisingly common, life scientists report Posted: 18 May 2012 10:28 AM PDT A large survey of human genetic variation shows that rare genetic variants are not so rare after all, and offers insights into human diseases. A team of scientists studied 202 genes in 14,002 people -- one of the largest ever in a sequencing study in humans. |
| How exercise affects the brain: Age and genetics play a role Posted: 18 May 2012 10:28 AM PDT Findings suggest that the effects of exercise on memory depend on the age of the exerciser; underlying genetic mechanisms matter, too. |
| Sutureless aortic valve replacement a North American first Posted: 18 May 2012 10:25 AM PDT A surgical milestone was reached on May 1st with a sutureless aortic valve replacement through a thoracic incision just 5 centimeters long. The two patients in their seventies who underwent this innovative procedure were doing well only one week after their operations. |
| Emotionally intelligent people are less good at spotting liars Posted: 18 May 2012 05:13 AM PDT People who rate themselves as having high emotional intelligence (EI) tend to overestimate their ability to detect deception in others. |
| Google goes cancer: Search engine algorithm finds cancer biomarkers Posted: 17 May 2012 04:31 PM PDT The strategy used by Google to decide which pages are relevant for a search query can also be used to determine which proteins in a patient's cancer are relevant for the disease progression. |
