How Does Your Brain Respond When You Think About Gambling Or Taking Ri
Should you leave your comfortable job for one that pays better but is less secure? Should you have a surgery that is likely to extend your life but poses some risk that you will not survive the operation? Should you invest in a risky startup company whose stock may soar even though you could lose your entire investment? In the Jan. 26 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions. Lava Lamp-Like Process Caused World's Largest Zinc Deposit
For more than two decades, geologists have scoured the ores and rocks surrounding the world's largest zinc deposit at Red Dog, Alaska, for clues as to how this giant ore body formed. In some zinc deposits elsewhere, volcanic activity was responsible for bringing metals to the upper levels of the Earth's crust. But at Red Dog, which lies about 85 miles north of the Arctic Circle, there are no obvious signs of volcanic activity to explain the presence of so much zinc. Locating the Source of the Plame Leak

Archerfish exhibit the remarkable ability to hunt for insects and other small terrestrial animals by firing precisely aimed streams of water that knock prey onto the water's surface. These water shots were once thought to be all-or-none in quality, but researchers have now discovered new levels of sophistication in the archerfish's hunting strategy that shed light on how this impressive predatory behavior has evolved. Rust never sleeps, until now
Dumb materials succumb to rust, but smart materials might be able to heal themselves.Researchers in Europe have devised a novel nano coating for metals and alloys that forms a very thin gel-like layer on the material. If this coating is damaged, the metal would normally be exposed to the elements. However, the nano particles contain [...] While Under Pressure Those Most Likely To Succeed Will Most Likely Fai
New research published in the latest issue of Psychological Science finds that individuals higher in working memory capacity (HWM) are more likely to be negatively impacted by performance pressure on math tests than those lower in working memory capacity (LWM). Working memory is a short-term system that holds information relevant to performance and ensures task focus. The Impeachment Trial of President Andrew Johnson: Supplement to the C
