TSA to retest airport body scanners for radiation
Does this make you feel safer? The TSA is going to retest the radiation levels of all its airport body scanners after maintenance records on some showed levels 10 times higher than expected. Also this:
The TSA is responsible for the safety of its own X-ray devices. The U.S. Food and Drug Administration has said it does not routinely inspect airport X-ray machines because they are not considered medical devices. The TSA’s airport scanners are exempt from state radiation inspections because they belong to a federal agency.

David Horowitz Takes on Muslim Students at Brooklyn College
So who are the real hate-mongers here? David Horowitz speaks at Brooklyn College while under heavy security. To me, the key quote is this:
Mr. Horowitz began by ruefully observing, “When I went to college you didn’t need all of this security on campus, but things have changed and that’s the reason we now need checkpoints on campuses. Checkpoints are essential to defend against terrorists and Jew haters.” Adding that he has been verbally and physically assaulted on campuses around the country for his forthright views, he said, “Our campuses are controlled by liberal fascists and it is a movement to suppress the free speech rights of conservatives.”

Random variations are still too large for climate models
The uncertainty of science: a paper published today in Geophysical Research Letters has concluded that the the long term random variations of the climate, sometimes lasting as long as three or four decades, are large enough to hide any actual changes to the climate. In the quote from the abstract below, the term “random walk” is jargon for a long term random fluctuation having nothing to do with climate change.
This result indicates that the shorter records may not totally capture the random variability of climate relevant on the time scale of civilizations, for which the random walk length is likely to be about 30 years. For this random walk length, the observed standard deviations of maximum temperature and minimum temperature yield respective expected maximum excursions on land of 1.4 and 2.3°C and over the ocean of 0.5 and 0.7°C, which are substantial fractions of the global warming signal.
In other words, it might simply be too soon to be making predictions about the climate, based upon the presently available data.

Putting ISS to use
Putting ISS to use. Key quote:
Under consideration is using the entire station and its six-person crew as an analog for a deep-space human exploration vehicle en route to Mars. An internal team is studying the feasibility and value of such an exercise in the summer of 2012. “We might start with a small window, like a 30-day window, with actual time delays with what we’d expect with a Martian communications system,” Gerstenmaier says. “We may freeze our consumables on station, in the sense of saying that we’ve started our voyage to Mars, and see how well we do in our predictions.”

New NPR video
A new NPR video from James O’Keefe: This time NPR executives are shown arranging an anonymous donation from the Muslim Brotherhood front group, in direct contradiction to their official claims after the first video was released that “The fraudulent organization represented in this video repeatedly pressed us to accept a $5 million check, with no strings attached, which we repeatedly refused to accept.”

Bill would set aside $60 million to develop in-vehicle alcohol detectors
There are so many ways this is wrong and illegal I can’t begin to count them: Senators Tom Udall (D-New Mexico) and Bob Corker (R-Tennessee) want to set aside $60 million to develop in-vehicle alcohol detectors that could be installed in all cars. You would have to use it before your car would start.
Putting aside the constitutional issues, isn’t there that federal debt to worry about?

Why public sector unions are losing – and can’t stop it if they tried
Why public sector unions are losing – and can’t stop it if they tried. Key quote:
This is why the Wisconsin Democratic Senators were in the minority in the first place. There is no reason for ninety percent of the population to rally for benefits that accrue to only ten percent of the workforce when they themselves are cut out of those benefits. So Wisconsin Democrats found themselves a powerless minority, whose only recourse was to run and…hope that tomorrow a new world would dawn. Such hopes are foolishness. And the Wisconsin Republican Senators showed them exactly why that is so. [emphasis in original]
