Neuroeconomists confirm Warren Buffett's wisdom: Brain research suggests an early warning signal tips off smart traders

Posted: 07 Jul 2014 12:25 PM PDT

Investment magnate Warren Buffett has famously suggested that investors should try to 'be fearful when others are greedy and be greedy only when others are fearful.' That turns out to be excellent advice, according to the results of a new study that looked at the brain activity and behavior of people trading in experimental markets where price bubbles formed.

World's biggest-ever flying bird discovered: Twice as big as the royal albatross

Posted: 07 Jul 2014 12:24 PM PDT

Scientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. With an estimated 20- to 24-foot wingspan, the creature surpassed the previous record holder -- an extinct bird named Argentavis magnificens -- and was twice as big as the royal albatross, the largest flying bird today. Computer simulations show that the bird's long slender wings helped it stay aloft despite its enormous size.

Neandertal trait in early human skull suggests that modern humans emerged from complex labyrinth of biology and peoples

Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals.

Solid-state physics: Consider the 'anticrystal'

Posted: 07 Jul 2014 10:43 AM PDT

For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Physicists now have evidence that a new concept should undergird our understanding of most materials: the anticrystal, a theoretical solid that is completely disordered.
