Berlin, Nov 26 : The Hubble Space Telescope has captured the image of a pair of stars that are two of our galaxy’s most massive stars.
They have, until recently, been shrouded in mystery, but the new image shows them in greater detail than ever before.
The image shows a pair of colossal stars, WR 25 and Tr16-244, located within the open cluster Trumpler 16. This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth.
The Carina Nebula contains several ultra-hot stars, including these two star systems and the famous blue star Eta Carinae, which has the highest luminosity yet confirmed.
Geneva - Global concentrations of greenhouse gases continued to increase in 2007, a report issued Tuesday said, with carbon dioxide rates reaching the highest level ever recorded.
The major cause of the gas emissions was human activities like burning fossil fuels and agriculture, the World Meteorological Organization (WMO) reported, adding that methane gas emissions had their greatest increase since 1998.
Sacramento, Nov 25 : The Transportation Department of Northern California, which has banned cell phones in cars, is allowing people headed to Tahoe for the holidays to turn their devices on, to test the efficacy of a new software program in sending information regarding traffic conditions to travellers’ handsets.
The new software, called Traffic Pilot, can give a real-time colour-coded map on the cell phone showing how fast traffic ahead is going.
According to sponsors, it''''s a major step towards ‘real time’ tools to battle congestion, basically turning car cabins into commute command centers.
Phones can be programmed to give drivers verbal warnings about problems ahead.
Washington, November 25 : Researchers at the University of Utah have created a synthetic version of the superglue that sandcastle worms combine with sand and shell to build their sturdy tube-shaped homes, and believe that it may one day be used to repair shattered bones in knees, other joints and the face.
"You would glue some of the small pieces together," says Russell Stewart, associate professor of bioengineering, and senior author of the study to be published online within a week in the journal Macromolecular Biosciences.
Washington, Nov 25 : A new study has found that telephone counselling may be as effective as face-to-face counselling when it comes to weight loss maintenance.
According to researchers, face-to-face and telephone follow-up sessions appear to be more effective in the maintenance of weight loss for women from rural communities compared with weight loss education alone.
Washington, November 24 : University of Liverpool researchers reckon that the modern human foot might have first appeared about 1.8 million years ago, but their ape-like ancestors probably took to walking several million years earlier.
Researcher Evie Vereecke believes the feet of the ancestors at the time would have been more “floppy” and ape like than humans’.
She joined forces with University of Antwerp researcher Peter Aerts to look at the flexible feet of modern gibbons to find out more about how they walk.
Since it is very difficult to work with gibbons in the lab, the researchers sought access to a troop of the semi-wild apes just down the road at Belgium''s Wild Animal Park of Planckendael.
