| Astronomers discover oldest star: Formed shortly after the Big Bang 13. 7 billion years ago Posted: 09 Feb 2014 05:08 PM PST A team of astronomers has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists a clearer idea of what the Universe was like in its infancy.  |
| Surprising new clue to the roots of hunger, neurons that drive appetite Posted: 07 Feb 2014 10:29 AM PST A scientific team has made a surprising discovery about the brain's hunger-inducing neurons, a finding with important implications for the treatment of obesity.  |
| Credit card-sized device could analyze biopsy, help diagnose pancreatic cancer in minutes Posted: 06 Feb 2014 12:53 PM PST Scientists and engineers are developing a low-cost device that could help pathologists diagnose pancreatic cancer earlier and faster. The prototype can perform the basic steps for processing a biopsy, relying on fluid transport instead of human hands to process the tissue.  |
| For depression, relapsers go to the front of the brain Posted: 22 Aug 2011 06:15 AM PDT Depression is increasingly recognized as an illness that strikes repeatedly over the lifespan, creating cycles of relapse and recovery. This sobering knowledge has prompted researchers to search for markers of relapse risk in people who have recovered from depression. A new paper suggests that when formerly depressed people experience mild states of sadness, the nature of their brains' response can predict whether or not they will become depressed again.  |
| Invisible Surgery: Appendix Removed Through Patient's Vagina Posted: 14 Jan 2009 05:36 PM PST Breaking new ground in what many surgeons consider the next frontier in minimally invasive surgery, surgeons have successfully performed an appendectomy with no abdominal incision. The appendix was removed through a small incision in the patient's vagina.  |
