Antarctic dinos

Scientists have discovered dinosaur fossils in Antarctica's Vega Island, adding to the evidence that land once connected that continent, South America and Australia.

An ancient bird's remains were found, and among dinosaur fossils were giant marine reptiles and the tooth of a duck-billed dinosaur, or hadrosaur. Duck-bills were previously found only in the Americas.

Scientists on the dig include experts from the Smithsonian Institution and Argentina's Museo de la Plata.

Airborne archaeology

An airborne radar developed by NASA has detected the remnants of previously unknown ancient temples at Ankor, Cambodia. The famous complex covers 100 square miles and includes about 1,000 known temples.

"The radar images make apparent many features that are not readily identifiable on the ground," said Dr. Anthony Freeman, a radar scientist at the Jet Propulsion Laboratory, Pasadena. "We can see differences in vegetation structure and some features that are obscured by vegetation cover."

Mind over matter

A positive attitude about physical health may help older adults avoid depression.

A University of Utah study shows that a person who insists, despite evidence to the contrary, that he or she is not sick may ward off depression.

The researchers found that the simple question "Do you consider yourself a sick person?" was more significantly associated with depression than perceived health status.

Amanda Barusch, Anissa Rogers and Soleman H. Abu-Bader from the Social Research Institute of the Graduate School of Social Work interviewed 100 chronically ill patients enrolled in community-based care programs.

The patients were asked questions about their health, social support, ability to complete daily tasks and frequency of depressive symptoms. More than a third reported significant depressive symptoms.

They also were asked whether they considered themselves "sick."

"Most would say things like, `I'm not sick because I can still take care of myself,' `I may be disabled, but I'm not sick,' or `I don't like to think of myself as sick,' " Barusch said.

Those who considered themselves sick scored higher on a depression scale than those who did not.

The researchers say their results highlight the importance of avoiding negative labels as well as the need to address mental health needs of chronically ill patients.
