In the early hours of Tuesday, August 20, a comet estimated to be only sixty to a hundred feet across dove into the sun, causing a huge solar explosion.

Just before the comet hit, a coronal mass ejection exploded off the sun’s surface. While there is no known reason that there would be a connection between a CME and the impact of a tiny comet, this has been observed before. The CME was emitted from the opposite side of the sun that was struck by the comet, and appears to have begun before the comet struck.

The speed of light may be the key to our getting off this planet. NASA physicist Harold G. White and his team are trying to determine whether faster-than-light travel–a "Star Trek"-type warp drive–might someday be possible (NOTE: Subscribers can still listen to this show). In the July 23rd edition of the New York Times, Danny Hakim quotes White as saying, "Space has been expanding since the Big Bang 13.7 billion years ago, and we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve gone receding away from each other at very rapid speeds.

Researchers at MIT have successfully implanted false memories in mice. Using a technique called optogenetics, researchers were able to isolate neurons controlling a single memory in the brain, tag them, then later stimulate them with light to induce the memory.

“If mice had Hollywood, this would be ‘Inception’ for them,” said Steve Ramirez, one of the lead researchers of the study, referring to the 2010 science-fiction film. The study was published online in the journal Science.

The Greenland ice sheet is not only melting from above, but also from below. It has been discovered that this is caused by heat flowing up from Earth’s mantle. It’s variable across Greenland, absent in some places and intense in others. Last summer, NASA satellites revealed that the surface of Greenland’s massive ice sheet had melted over an unusually large area. NASA has been monitoring the Greenland melt for 30 years, July of 2012 was "unprecedented," partly because it was so large and partly because it occurred at the COLDEST part of the country, Summit station. The thawed area went from 40% of the ice sheet to 97% in just four days, starting on July 8th, 2012.read more
