A Credit Card-Sized, Arduino-Based Game Device (Video)

Slashdot - Mon, 28/07/2014 - 7:50pm
Slashdot's Tim Lord was cruising the halls at OSCON, where he spotted Kevin Bates and his tiny Arduino-based device, called the Arduboy. On Kevin's Tindie.com sales page, he says the games it can run include, "Space Rocks, Snake, Flappy Ball, Chess, Breakout, and many more...The most exciting one could be made by you!" || His work with Arduboy got Kevin invited to the recent White House Maker Faire, where he rubbed shoulders (and shot selfies with) Bill Nye the Science Guy, Will.i.am from the Black Eyed Peas, and Arduino creator Massimo Banzi. || Does Kevin have a Kickstarter in the works? There's nothing about Arduboy on Kickstarter.com, and given the Arduboy's simplicity and low price (currently $50), plus stories about it everywhere from Time.com to engadget to Slashdot, he may not need any financing or capital to make his idea succeed.

Stimulation of brain region restores consciousness to animals under general anesthesia

Science Daily - Mon, 28/07/2014 - 7:40pm
Stimulating the ventral tegmental area, one of two dopamine-producing regions in the brain, was able to arouse animals receiving general anesthesia with either isoflurane or propofol. The same effect did not result from stimulation of the substantia nigra.

Glucose 'control switch' in the brain key to both types of diabetes

Science Daily - Mon, 28/07/2014 - 7:39pm
Researchers have pinpointed a mechanism in part of the brain that is key to sensing glucose levels in the blood, linking it to both type 1 and type 2 diabetes.

Cell's recycling center implicated in division decisions

Science Daily - Mon, 28/07/2014 - 7:39pm
Most cells do not divide unless there is enough oxygen present to support their offspring, but certain cancer cells and other cell types circumvent this rule. Researchers have now identified a mechanism that overrides the cells' warning signals, enabling cancers to continue to divide even without a robust blood supply. In the process, the researchers found that lysosomes -- the cell's protein 'recycling centers' -- help govern cell division decisions.

Brain's habenula signals how bad things could be

Science Daily - Mon, 28/07/2014 - 7:39pm
An evolutionarily ancient and tiny part of the brain tracks expectations about nasty events, according to new research. The study demonstrates for the first time that the human habenula, half the size of a pea, tracks predictions about negative events, like painful electric shocks, suggesting a role in learning from bad experiences.

Global warming amplifier: Rising water vapor in upper troposphere to intensify climate change

Science Daily - Mon, 28/07/2014 - 7:39pm
A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere -- a key amplifier of global warming -- will intensify climate change impacts over the next decades. The new study is the first to show that increased water vapor concentrations in the atmosphere are a direct result of human activities.

Researchers produce record-length mirror-image protein

Science Daily - Mon, 28/07/2014 - 7:36pm
Biochemists have reported an advance in the production of functional mirror-image proteins. In a new study, they have chemically synthesized a record-length mirror-image protein and used this protein to demonstrate that a cellular chaperone, which helps "fold" large or complex proteins into their functional state, has a previously unappreciated talent -- the ability to fold mirror-image proteins. These findings will greatly facilitate mirror-image protein production for applications in drug discovery and synthetic biology.

Learning the smell of fear: Mothers teach babies their own fears via odor, animal study shows

Science Daily - Mon, 28/07/2014 - 7:36pm
Babies can learn what to fear in the first days of life just by smelling the odor of their distressed mothers’, new research suggests. And not just “natural” fears: If a mother experienced something before pregnancy that made her fear something specific, her baby will quickly learn to fear it too -- through her odor when she feels fear.

Ask Slashdot: Preparing an Android Tablet For Resale?

Slashdot - Mon, 28/07/2014 - 7:07pm
UrsaMajor987 (3604759) writes I have a Asus Transformer tablet that I dropped on the floor. There is no obvious sign of damage but It will no longer boot. Good excuse to get a newer model. I intend to sell it for parts (it comes with an undamaged keyboard) or maybe just toss it. I want to remove all my personal data. I removed the flash memory card but what about the other storage? I know how to wipe a hard drive, but how do you wipe a tablet? If you were feeling especially paranoid, but wanted to keep the hardware intact for the next user, what would you do?
