Guarav Khanna, a black hole physicist at the University of Massachusetts Dartmouth in the US, has managed to build a powerful and extremely cheap supercomputer using old PlayStation 3s (PS3s), and he’s used it to publish several papers on black holes.
His research focusses on finding gravitational waves, which are curvatures in space-time that ripple out from a violent astrophysical event, such as two black holes colliding. They were first predicted by Einstein’s theory of general relativity, but no one has been able to observe them." Link to Original Source top

That’s around 18,000 kits in all, co-founder Alex Klein confirmed to TechCrunch. “They are all in the wild, they are out of our hands. About 1,000 have arrived already — the early bird kits." Link to Original Source top
A number of schools have started using a program called CourseSmart, which uses e-book analytics to alert teachers if their students are studying the night before tests, rather than taking a long-haul approach to learning.
In addition to test scores, the CourseSmart algorithm assigns each student an “engagement index” which can determine not just if a student is studying, but also if they’re studying properly.

drkim (1559875) writes "A computerized sniper scope allows even beginning shooters to target accurately at long ranges — a "real-life" aimbot.
The scope has you designate the point you wish to hit, it then calculates all the variables of where the rifle should be pointed, and then while you hold down the trigger, the scope decides when to make the shot. It can even send multiple bullets to the same spot.

Lytro newest camera lets you change perspective, focus, content based filters
drkim (1559875) writes "Lytro previous camera let you adjust focus after the picture was taken, this new version also lets you shift perspective and apply cool post effects, based on content, long after the picture is taken.
The image shift could allow for 3-D imaging.
On the sample page there are 'live' examples. Try clicking and dragging; single clicking; or double clicking to get different effects." Link to Original Source top
The advertising industry wants to make "Do Not Track" mean "It's OK To Track"
drkim (1559875) writes "The advertising industry wants to change the definition of "Do Not Track" into "Give me all your data." A representative of the DMA says, "Marketing fuels the world. It is as American as apple pie and delivers relevant advertising to consumers about products they will be interested at a time they are interested."
"DNT should permit it as one of the most important values of civil society...Marketing as a permitted use would allow the use of the data to send relevant offers to consumers through specific devices they have used."" Link to Original Source top

A researcher in New York is building fish robots that infiltrate schools of fish and take them over. The cyberfish could be used to lead fish away from unsafe underwater turbines or other hazards.
An assistant professor at the Polytechnic Institute of New York University, studied the fluid dynamics of leader fish to build a realistic fishbot. The university says the technology could even be expanded to tap energy from the movement of water to charge its batteries." Link to Original Source top
