UCLA backs off firing politically incorrect professor
Good news for science: UCLA has backed off from its plan to fire a politically incorrect professor, giving Dr. James Enstrom an eight month reprieve as it reviews his case.

Scientists predict when the first Earthlike planet will be discovered
Don’t bet the bank on this: In a preprint paper posted tonight on the astro-ph website, scientists predict the discovery of the first Earthlike extrasolar planet — using statistical analysis alone! Fun quote:
Using a bootstrap analysis of currently discovered exoplanets, we predict the discovery of the first Earth-like planet to be announced in the first half of 2011, with the likeliest date being early May 2011.
More data suggests ocean conveyor belt more complex than expected
Back to the climate-theory drawing board: A paper published today in Nature Geoscience suggests that the ocean conveyor belt that brings warm water to the northern Atlantic is far more complex than the original theories proposed. These results strengthen earlier reports that also questioned the conveyor belt theory.
The pain of spacesuit gloves
The number one injury reported by astronauts appears to be fingernail and hand injuries resulting from the use of spacesuit gloves. Key quote:
A previous study of astronaut injuries sustained during spacewalks had found that about 47 percent of 352 reported symptoms between 2002 and 2004 were hand related. More than half of these hand injuries were due to fingertips and nails making contact with the hard “thimbles” inside the glove fingertips. In several cases, sustained pressure on the fingertips during EVAs caused intense pain and led to the astronauts’ nails detaching from their nailbeds, a condition called fingernail delamination.
14 objects discovered beyond Neptune
Using archival Hubble Space Telescope images astronomers have discovered 14 objects orbiting the Sun beyond Neptune. Key quote:
The newfound objects range from 25 to 60 miles across (40 to 100 kilometers), said the researchers.
The Argument Clinic
An evening pause: The argument clinic sketch from Monty Python.
Saturn from above
This breath-taking image of Saturn and its rings was taken by Cassini on July 19, 2009 and posted on the Cassini image gallery on August 27, 2010.
Dawn’s status as it heads to Vesta
All systems go! The project engineer of the Dawn mission has posted a very detailed update (as of August 30), describing the spacecraft’s status in its journey to the asteroid Vesta.
WhiteKnightTwo back in the air
Good news for private space! Scaled Composites put WhiteKnightTwo back in the air today, only three weeks after one of its landing gears failed during a landing. You can read the test flight logs here.
ISS’s life expectancy
Engineers are reviewing the life expectancy of the International Space Station, in light of the desire of politicians to keep it operating through the 2020s. Intriguing quote:
Airlines and airplane contractors commonly inspect aircraft for such fractures, but with the space station out of reach more than 200 miles up, engineers rely on complex models to predict their growth in orbit.
shuttle variation alive?
The space war over NASA continues. The Orlando Sentinel has an article today selling the merits of the Team Direct concept that would use most of the shuttle hardware to replace it.
The Westerner
An evening pause: The Westerner (1940). Gary Cooper is wonderful, but it is Walter Brennan as Judge Roy Bean who steals the show.
