| Comet theory false: Doesn't explain Ice Age cold snap, Clovis changes, animal extinction Posted: 13 May 2014 08:36 AM PDT New research has demonstrated again that a comet didn't spark climate change at the end of the Ice Age, killing the Clovis peoples and causing mass animal extinction. Supposed impact indicators are too old or too young to indicate an ancient comet that proponents claim sparked a late Ice Age calamity, according to new research. The researchers found previous dating of Ice Age boundary layers by proponents contained widespread errors.  |
| Odd planet, so far from its star: Gas giant 155 light years from our solar system Posted: 13 May 2014 08:31 AM PDT A gas giant has been added to the short list of exoplanets discovered through direct imaging. It is located around GU Psc, a star three times less massive than the Sun and located in the constellation Pisces.  |
| Diets rich in antioxidant resveratrol fail to reduce deaths, heart disease or cancer Posted: 12 May 2014 06:41 PM PDT A study of Italians who consume a diet rich in resveratrol -- the compound found in red wine, dark chocolate and berries -- finds they live no longer than and are just as likely to develop cardiovascular disease or cancer as those who eat or drink smaller amounts of the antioxidant.  |
| Alcohol and drugs: Not just for modern humans Posted: 12 May 2014 12:50 PM PDT Unlike most modern humans, the prehistoric people of Europe did not use mind-altering substances simply for their hedonistic pleasure. Researchers contend that their use was an integral part of prehistoric beliefs, and that these substances were seen to aid in communication with the spiritual world.  |
| Bullying may have long-term health consequences Posted: 12 May 2014 12:48 PM PDT Bullied children may experience chronic, systemic inflammation that persists into adulthood, while bullies may actually reap health benefits of increasing their social status through bullying, according to researchers.  |
| Having a sense of purpose may add years to your life Posted: 12 May 2014 09:43 AM PDT Feeling that you have a sense of purpose in life may help you live longer, no matter what your age, according to new research. The research has clear implications for promoting positive aging and adult development, says the lead researcher.  |
| Posted: 12 May 2014 08:25 AM PDT Researchers have discovered a natural molecule that could be used to treat insulin resistance and type 2 diabetes. The molecule, a derivative of omega-3 fatty acids, mimics some of the effects of physical exercise on blood glucose regulation.  |
| Mars canyons: Against the current with lava flows Posted: 12 May 2014 07:14 AM PDT An Italian astronomer in the 19th century first described them as 'canali' – on Mars' equatorial region, a conspicuous net-like system of deep gorges known as the Noctis Labyrinthus is clearly visible. The gorge system, in turn, leads into another massive canyon, the Valles Marineris, which is 4,000 km long, 200 km wide and 7 km deep. Both of these together would span the US completely from east to west.  |
| Toxicologists outline key health and environmental concerns associated with hydraulic fracturing Posted: 09 May 2014 02:25 PM PDT Since the rise in the use of hydraulic fracturing of shale to produce natural gas and oil, many have debated the merits and detractions of the practice. Scientists outline how toxicological sciences can be used to determine what risks may or may not be associated with fracking.  |
| Frequent arguments with family, friends linked to doubling in death risk in middle age Posted: 08 May 2014 04:25 PM PDT Frequent arguments with partners, relatives, or neighbors may boost the risk of death from any cause in middle age, suggests research. Men and those not in work seemed to be the most vulnerable, the findings indicate. Constant arguing seemed to be the most harmful for health. The evidence also suggests that supportive social networks and strong relationships are good for general health and wellbeing.  |
