NASA has begun to wind down construction of the rockets and spacecraft that were to have taken astronauts back to the Moon — effectively dismantling the US human spaceflight programme despite a congressional ban on its
doing so.
Legislators have accused President Obama’s administration of contriving to slip the termination of the Constellation programme through the back door to avoid a battle on Capitol Hill.

“A new type (or phase) of star has been characterized by Case Western Reserve University scientists in a paper submitted to Physical Review Letters. The ‘electroweak’ star is a stellar corpse too massive to be a quark star, yet too light to collapse into a black hole. It crushes and burns the quarks inside, generating an outward radiation pressure that acts against gravity. Interestingly, the interior is predicted to be a 'Big Bang factory,' forcing the electromagnetic and weak forces to collapse as one (hence 'electroweak') — a condition that hasn't been seen elsewhere in our universe since moments after the Big Bang.”
The article notes that the first calculations on electroweak stars pegged them as an intermediate stage on the way to a black-hole collapse, lasting at most a second. The new calculations suggest that electroweak stars could persist for millions of years.

Parity was long thought to be a fundamental law of nature. It essentially states that the universe is neither right- nor left-handed — that the laws of physics remain unchanged when expressed in inverted coordinates. In the early 1950s it was found that the so-called weak force, which is responsible for nuclear radioactivity, breaks the parity law. However, the strong force, which holds together subatomic particles, was thought to adhere to the law of parity, at least under normal circumstances.
Now this law appears to have been broken by a team of about a dozen particle physicists, including Jack Sandweiss, Yales Donner Professor of Physics. Since 2000, Sandweiss has been smashing the nuclei of gold atoms together as part of the STAR experiment at RHIC, a 2.4-mile-circumference particle accelerator, to study the law of parity under the resulting extreme conditions.

“Internet research firm Hitwise just broke the news: last week, Facebook attracted 7.07 percent of the internet traffic in the USA, compared to 7.03 percent for Google. This is the first time google.com has been out of the top spot since it surpassed MySpace in 2007, and reflects a change in the way people use internet. They tend to privilege social interaction sites above 'passive' search engines.”
Facebook still has a ways to go if you include Google's non-search properties, which bring the total up to 11.03% of traffic.

Popular histories too often present perpetual motion machines as “freaks and curiosities” of engineering without telling us just how they were understood at the time. They also fail to inform us that even in the earliest history of science and engineering, many persons were able to see the futility and folly of attempts to achieve perpetual motion.
Sometimes a particular device comes to us with a label, such as “Bishop Wilkins’ magnetic perpetual motion machine.” Popular articles leave the impression that the inventor believed it was a perpetual motion machine. In fact, very often the device was presented and described to illustrate the futility of the quest for perpetual motion.
