| Interplanetary dust particles could deliver water and organics to jump-start life on Earth Posted: 24 Jan 2014 01:12 PM PST Researchers have discovered that interplanetary dust particles could deliver water and organics to the Earth and other terrestrial planets. "It is a thrilling possibility that this influx of dust has acted as a continuous rainfall of little reaction vessels containing both the water and organics needed for the eventual origin of life on Earth and possibly Mars," said Hope Ishii, study co-author. |
| New genes spring, spread from non-coding DNA Posted: 23 Jan 2014 11:20 AM PST "Where do new genes come from?" is a long-standing question in genetics and evolutionary biology. A new study shows that new genes can spring from non-coding DNA more rapidly than expected. |
| Posted: 23 Jan 2014 11:17 AM PST Scientists have used advanced imaging techniques to provide a window into how the brain makes memories. These insights into the molecular basis of memory were made possible by a technological tour de force never before achieved in animals: a mouse model in which molecules crucial to making memories were given fluorescent "tags" so they could be observed traveling in real time in living brain cells. |
| Death row confessions and the last meal test of innocence Posted: 23 Jan 2014 09:58 AM PST Social circumstance often gives meals meaning, so it is logical that the last meals of those on death row may signify something beyond taste preference. While there are many factors that could contribute to last meal selection, this study is the first to provide evidence of a link between food selection and self-perceived guilt or innocence. These findings may be useful to the legal community in further assessing the innocence and perceived innocence of those who have received the death penalty in the past. |
| Natural Petroleum Seeps Release Equivalent Of Up To 80 Exxon Valdez Oil Spills Posted: 13 May 2009 10:09 AM PDT Twenty years ago, the oil tanker Exxon Valdez was exiting Alaska's Prince William Sound when it struck a reef in the middle of the night. What happened next is considered one of the nation's worst environmental disasters: 10.8 million gallons of crude oil spilled into the pristine Alaskan waters, eventually covering 11,000 square miles of ocean. Now, imagine 8 to 80 times the amount of oil spilled in the Exxon Valdez accident. According to new research, that's how much oil has made its way into sediments offshore from petroleum seeps near Coal Oil Point in the Santa Barbara Channel. |
| Posted: 31 Aug 2008 08:47 AM PDT Bipolar disorder is one of the most important psychiatric diseases, often associated with considerable treatment needs and tremendous social and occupational burden for both the individual and family (Pini et al., 2005). Previously also labeled manic-depressive illness, bipolar disorder is typically referred to as an episodic, yet lifelong and clinically severe mood (or affective) disorder. |
