Washington, Sept 17: Older problem gamblers are three to four times more likely to be suicidal than their younger counterparts, says a new study.

The research team involving Lia Nower, JD, PhD, of the Rutgers University Centre for Gambling Studies, and Alex Blaszczynski, Ph. D. of the University of Sydney, Australia has found that older gamblers who ask casinos to bar them from returning fear that they will kill themselves if they don't stop gambling.

Washington, September 17: Scientists at the Salk Institute for Biological Studies have discovered that the superior colliculus (SC) — a centre in the brain that helps orient the head and eyes towards something seen or heard — may also play a role in analysing the environment, and deciding whether one specific aspect is worth paying closer attention to than another.

Washington, Sept. 17: Democratic presidential candidate Barack Obama is fine-tuning the most basic element of his campaign to win the White House.

According to FOX News, Obama, whose slogan has long been “Change We Can Believe In,” has since the end of the Democratic National Convention in Denver in late August, altered his rallying cry to read as the “Change We Need.”

He advertises upcoming “Change We Need” rallies on his Web site. And he incorporates the modified phrase into his stump speeches.

Washington, September 17: A new research has revealed evidence that would dispel the ‘macho’ image of Paleo-Indians as big-game hunters par excellence, suggesting that they relied more on rabbits for their food.

Paleo-Indians were the ancient peoples of the Americas who were present at the end of the last Ice Age.

Since archaeologists found Clovis points lodged in the skeleton of a mammoth, they have viewed Paleo-indians as big-game hunters par excellence.

Nearly every book on the subject includes an image of a brawny hunter thrusting his spear into the side of a trumpeting mammoth. This macho view of Paleoindian prehistory has prevailed even though surprisingly little evidence exists to support it.

Washington, September 17: Scientists have warned that Polar bears and other rare species could become extinct, as latest figures show rapid melting of the Artic sea ice, which is at currently at a record low.

According to a report in ENN (Environmental News Network), scientists from the World Wildlife Fund (WWF), who are recording the ice cover over the North Pole, have said that less ice is predicted in the Arctic this year than in any other.

Washington, September 17: Emotions on people’s faces play a significant role in their recognition by others when they meet sometimes in the future, according to a study.

Researchers in the Netherlands and at Massachusetts General Hospital, led by Beatrice de Gelder, say that their study suggests that using naturalistic emotional faces and bodies in studies aimed at determining why some people find it difficult to recognise those whom they have met before may be very helpful in understanding face blindness.
