Washington, Dec 16 : New calculations have shown that eating goose eggs may help polar bears weather climate change, as it would provide the animals with an alternative source of food.

Polar bears, Ursus maritimus, are listed as a threatened species under the United States' Endangered Species Act and are classified as "vulnerable with declining populations" under IUCN's Red List.

The new calculations show that changes in the timing of sea-ice breakup and of snow goose nesting near the western Hudson Bay could provide at least some polar bears with an alternative source of food.

Washington, Dec 16 : A new project, led by a University of Virginia (U. Va.) professor, is all set to survey more than 100,000 Milky Way stars, in an attempt to know more about the history of our galaxy.

The project, the Apache Point Observatory Galactic Evolution Experiment, or APOGEE, is one of four experiments of the new Sloan Digital Sky Survey III, using the astronomical facilities at Apache Point Observatory in New Mexico.

Washington, Dec 16 : NASA has outlined its top ten science, exploration and discovery stories of 2008, the year in which the agency celebrated its 50th birthday.

The top ten accomplishments are:

London, Dec 16 : A team of astronomers have reported that a new camera is giving them the sensitivity they need to spot habitable extrasolar planets, which are nearly as small as Earth.

According to a report in Nature News, the team observed a planet - WASP-10b, which is around three times the mass of Jupiter orbiting the star WASP-10.

The team determined that the star is about 300 light years from Earth, and measured precisely how much the star dimmed as the planet passed in front of it.

Washington, Dec 16 : Researchers from Tel Aviv University suggest that older fathers are likely to have boys with poor social abilities.

The study revealed that older dads are more likely to have boys with autism and lower IQs.

"There is a growing body of data showing that an advanced age of parents puts their kids at risk for various illnesses," said lead researcher Dr. Mark Weiser from TAU's Sackler School of Medicine.

"Some illnesses, such as schizophrenia, appear to be more common the older parents get. Doctors and psychologists are fascinated by this, but don't really understand it. We want to know how it works," he added.

Washington, Dec 16 : A new model has revealed that one-third of all solar systems may contain super-Earths, which indicates that life may be abundant in the Universe.

Cold "Super-Earths", which are giant, "snowball" planets that astronomers have spied on the outskirts of faraway solar systems, could potentially support some kind of life, they have found.

"We know there are a lot of super-Earths out there, and the next generation of telescopes will be even better at spotting them," said Scott Gaudi, assistant professor of astronomy at Ohio State University.
