Hubble Confirms Cosmic Acceleration With Weak Lensing
This image shows a smoothed reconstruction of the total (mostly dark) matter distribution in the COSMOS field, created from data taken by the NASA/ESA Hubble Space Telescope and ground-based telescopes. It was inferred from the weak gravitational lensing distortions that are imprinted onto the shapes of background galaxies. The color coding indicates the distance of the foreground mass concentrations as gathered from the weak lensing effect. Structures shown in white, cyan and green are typically closer to us than those indicated in orange and red. To improve the resolution of the map, data from galaxies both with and without redshift information were used. The new study presents the most comprehensive analysis of data from the COSMOS survey. The researchers have, for the first time ever, used Hubble and the natural "weak lenses" in space to characterise the accelerated expansion of the universe. Credit: NASA, ESA, P. Simon (University of Bonn) and T. Schrabback (Leiden Observatory)From Reuters:
A group of astronomers [1], led by Tim Schrabback of the Leiden Observatory, conducted an intensive study of over 446 000 galaxies within the COSMOS field, the result of the largest survey ever conducted with Hubble. In making the COSMOS survey, Hubble photographed 575 slightly overlapping views of the same part of the Universe using the Advanced Camera for Surveys (ACS) onboard Hubble. It took nearly 1000 hours of observations.

The Secrets Of Firefly's Shepherd Book Will Finally Be Revealed
From The Escapist:
Shepherd Book, possibly the most mysterious character on Joss Whedon's ill-fated space-western Firefly is to star in in a comic book that will finally let us in on his past.
A character with a mysterious past is hardly a new idea for Joss Whedon, by Firefly's Shepherd Book was a particularly good one. Played by Ron Glass, the Shepherd - the term used for men of the cloth on the show - clearly had not been a God's servant all his life, and some pretty high-level connections with the Alliance. What made the mystery extra-potent however was that the show got cancelled, and we never got to find out what his mysterious past actually was.

If it kept cooperating, Blanchard would touch down directly above the room that held the Koechert Diamond Pearl. He steered his parachute toward his target.

Revealed: Why Hot Water Freezes Faster Than Cold
Freezing depends on impurities (Vilhjalmur Ingi Vilhjalmsson/Getty)From New Scientist:
HOT water sometimes freezes faster than cold water - but why? This peculiar phenomenon has baffled scientists for generations, but now there is evidence that the effect may depend on random impurities in the water.
Fast-freezing of hot water is known as the Mpemba effect, after a Tanzanian schoolboy called Erasto Mpemba (see "How the Mpemba effect got its name"). Physicists have come up with several possible explanations, including faster evaporation reducing the volume of hot water, a layer of frost insulating the cooler water, and differing concentration of solutes. But the answer has been very hard to pin down because the effect is unreliable - cold water is just as likely to freeze faster.

DARPA Bounces Smart Radar Off Buildings To Track Individual Urban Vehicles From The Sky
Tracking from Above It's difficult to use radar in urban environments because of all the structures that get in the way. But by bouncing highly sensitive radar off of buildings' facades, DARPA hopes to lock onto individual vehicles from UAVs and track them through urban streets even when buildings block line of sight. Zemlinki From Popular Science:
Radar is great for tracking objects in the wide-open sky or even at sea, but when you try to take it to street level you run into some obstacles -- literally. Radar requires a good line of sight, and obstructions like buildings or terrain features can render radar useless. But now, using a handful of unmanned aircraft and technology that allows them to intelligently reflect radar off buildings, DARPA is developing a system that should be able to track individual vehicles even as they dart between skyscrapers and other structures.
