| Student deciphers 1,800-year-old letter from Egyptian soldier Posted: 19 Mar 2014 06:42 AM PDT A newly deciphered 1,800-year-old letter from an Egyptian solider serving in a Roman legion in Europe to his family back home shows striking similarities to what some soldiers may be feeling here and now. |
| Cultural hitchhiking: How social behavior can affect genetic makeup in dolphins Posted: 18 Mar 2014 06:22 PM PDT Researchers studying bottlenose dolphins that use sponges as tools to protect their sensitive beaks has shown that social behavior can shape the genetic makeup of an animal population in the wild. The research on dolphins in Shark Bay in Western Australia is one of the first studies to show this effect -- which is called cultural hitchhiking -- in animals other than people. |
| Fierce 2012 magnetic storm just missed us: Earth dodged huge magnetic bullet from the sun Posted: 18 Mar 2014 12:49 PM PDT On July 23, 2012, a huge magnetic storm propelled by two nearly simultaneous coronal mass ejections on the sun plowed through Earth's orbit. Luckily, Earth was on the other side of the sun at the time. Had the outburst hit Earth, however, it would have rivaled the largest magnetic storm to strike Earth in recorded history, possibly wreaking havoc with the electrical grid, satellites and GPS. |
| Precise reason for health benefits of dark chocolate: Thank hungry gut microbes Posted: 18 Mar 2014 12:47 PM PDT The health benefits of eating dark chocolate have been extolled for centuries, but the exact reason has remained a mystery -- until now. Researchers reported that certain bacteria in the stomach gobble the chocolate and ferment it into anti-inflammatory compounds that are good for the heart. |
| New evidence raises questions about the link between fatty acids and heart disease Posted: 17 Mar 2014 02:45 PM PDT A new study finds that the current level of evidence does not support guidelines restricting saturated fatty acid consumption to reduce coronary risk nor does it support high consumption of polyunsaturated fats -- such as omega 3 or omega 6 -- to reduce coronary heart disease. |
| Baby's life saved after 3-D printed devices were implanted restore his breathing Posted: 17 Mar 2014 09:49 AM PDT Garrett is just the second person whose life was saved with a new, bioresorbable device. He needed to be on a ventilator at pressure levels that had reached the maximum, and he was not improving. Often on strong medication, and even at times in a medically-induced coma because he would work against the ventilator if he was awake, Garrett's family learned about a procedure that might just change his life. |
| What’s so bad about feeling happy? Posted: 17 Mar 2014 06:59 AM PDT Why is being happy, positive and satisfied with life the ultimate goal of so many people, while others steer clear of such feelings? It is often because of the lingering belief that happiness causes bad things to happen, says a researcher. A new article reviews the concept of aversion to happiness, and looks at why various cultures react differently to feelings of well-being and satisfaction. |
| An experiment recreates the crust of Jupiter's moon Europa Posted: 14 Mar 2014 06:36 AM PDT Water, salts and gases dissolved in the huge ocean that scientists believe could exist below Europa´s icy crust can rise to the surface generating the enigmatic geological formations associated to red-tinged materials that can be seen on this Jupiter's satellite. This is confirmed by the experiment carried out in the laboratory with water, carbon dioxide and magnesium sulfate. |
| Husband's health, attitude loom large for happy long-term marriages Posted: 13 Mar 2014 01:44 PM PDT A husband's agreeable personality and good health appear crucial to preventing conflict among older couples who have been together a long time, according to a study. The report found that such characteristics in wives play less of a role in limiting marital conflict, perhaps because of different expectations among women and men in durable relationships. |
| Origin of life: Simulating how Earth kick-started metabolism Posted: 13 Mar 2014 06:27 AM PDT Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth -- a crucial biological function for all living organisms. The research could help scientists to understand whether it is possible for life to have emerged in similar environments on other worlds. |
