Newly discovered temperate planet Corot-9b could hold water

The Corot satellite strikes again with another fascinating planet discovery, this time the newly discovered gas giant Corot-9b may have an interior that closely resembles those of Jupiter and Saturn in our own Solar System.

Very few planets are temperate enough to allow the presence of liquid water, but the newly discovered Corot-9b is one of them. It was found on 16 May 2008 and orbits its star every 95.274 days, a little longer than Mercury takes to go round the Sun.

University of Arizona astronomers discover most primitive supermassive black holes known

Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known. The discovery, based largely on observations from NASA's Spitzer Space Telescope, will provide a better understanding of the roots of our universe, and how the very first black holes, galaxies and stars all came to be.

Medicare patients 5.5 times more likely to get cataract surgery than VA patients, study finds

INDIANAPOLIS – Patients seen at private facilities reimbursed by Medicare were more than 550 percent more likely to have routine cataract surgery than those who received their care from the Department of Veterans Affairs, a strong indication that the frequency of cataract surgery may be responsive to financial incentives to either or both the medical facility and the physicians who perform the procedure.

These findings from a large eight-year study are reported in the March 2010 issue of the American Journal of Medical Quality.

Fast growing primitive black holes may tell us why quasars resemble each other

Quasars are active and very powerful black holes at the centre of distant galaxies. The black holes are extremely massive weighing between 100 million and 10 billion solar masses and rotating around the super massive black hole is a disc of gas and dust. The inner ring of the disc moves faster than the outer rings. The movement causes the material in the rings to rub against each other, heating it and causing it to emit light.

Corot-9b: First temperate exoplanet sized up

"This is a normal, temperate exoplanet just like dozens we already know, but this is the first whose properties we can study in depth," says Claire Moutou, who is part of the international team of 60 astronomers that made the discovery. "It is bound to become a Rosetta stone in exoplanet research."

"Corot-9b is the first exoplanet that really does resemble planets in our solar system," adds lead author Hans Deeg. "It has the size of Jupiter and an orbit similar to that of Mercury."

Tomas moving away from Fiji Islands after causing damages

Cyclone Tomas hit the north and east areas of Fiji as a Category 4 Cyclone on the Saffir-Simpson Scale, and has now moved south of them. NASA's Tropical Rainfall Measuring Mission satellite captured an image of the heavy rains that were falling in Tomas during his swath of destruction in the Fiji Islands.

Cassini shows Saturnian roller derby

The seemingly serene orb of Saturn is in fact a gas giant with extraordinary patterns of charged particles and rough and tumble roller derbies for rings. Such are the findings of NASA's Cassini spacecraft since its arrival at Saturn in 2004 – they are combined in two review papers to be published in the March 19 issue of the journal Science.

Some bullies are just the shy type: New research shows a darker side to social anxiety disorder

FAIRFAX, Va., March 18, 2010—When you think of people suffering from social anxiety, you probably characterize them as shy, inhibitive and submissive. However, new research from psychologists Todd Kashdan and Patrick McKnight at George Mason University suggests that there is a subset of socially anxious people who act out in aggressive, risky ways—and that their behavior patterns are often misunderstood.

CoRoT-9b: Scientists reports discovery of a new Jupiter-sized planet 1500 light years from Earth

(Santa Barbara, Calif.) –– An international team of scientists, including several who are affiliated with UC Santa Barbara, has discovered a new planet the size of Jupiter. The finding is published in the March 18 issue of the journal Nature.

Modified home video game shows promise for improving hand function in teens with cerebral palsy

NEW BRUNSWICK, N.J. – Engineers at Rutgers University have modified a popular home video game system to help teenagers with cerebral palsy improve hand functions. In a pilot trial with three participants, the system improved the teens' abilities to perform a range of daily personal and household activities.

The modified system combined a Sony PlayStation 3 console and a commercial gaming glove with custom-developed software and games to provide exercise routines aimed at improving hand speed and range of finger motion.
