Dark Fluid: Dark Matter And Dark Energy May Be Two Faces Of Same Coin

Dark Fluid: Dark Matter And Dark Energy May Be Two Faces Of Same CoinFeb. 1, 2008Astronomers at the University of St Andrews believe they can "simplify the dark side of the universe" by shedding new light on two of its mysterious constituents.                            Dr HongSheng Zhao, of the University's School of Physics and Astronomy, has shown that the puzzling dark matter and its counterpart dark energy may be more closely linked than was previously thought.Only 4% of the universe is made of known material - the other 96% is traditionally labelled into two sectors,...

Major Clue in Long-Term Memory-Making

(Mar. 20, 2011) You may remember the color of your loved one's eyes for years. But how? Scientists believe that long-term potentiation (LTP) -- the long-lasting increase of signals across a connection between brain cells -- underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience.                        Researchers at Duke University Medical Center have found a cascade of signaling molecules that allows a usually very brief signal to last for tens of minutes, providing the brain framework for stronger connections (synapses)...

Two New SCAP Documents Help Improve Automating Computer Security Management

                              It's increasingly difficult to keep up with all the vulnerabilities present in today's highly complex operating systems and applications. Attackers constantly search for and exploit these vulnerabilities to commit identity fraud, intellectual property theft and other attacks. The National Institute of Standards and Technology (NIST) has released two updated publications that help organizations to find and manage vulnerabilities more effectively, by standardizing the way vulnerabilities are identified, prioritized and reported.   ...
