Google and Facebook might have finally gotten the average consumer riled up about privacy. -
20:24One day in 2010, Rutgers physicist Vitaly Podzorov watched a store employee showcase a kitchen gadget that vacuum-seals food in plastic. The demo stuck with him. The simple concept – an airtight seal around pieces of food – just might apply to his research: developing flexible electronics using lightweight organic semiconductors for products such as video displays or solar cells.

Former Palm CEO Rubinstein Exits HP to 'Take a Well-Deserved Break'
Ex-Apple guru Jon Rubinstein came out of retirement to run Palm. Now he's leaving Hewlett-Packard, the company that acquired Palm for its webOS mobile operating system.Rubinstein had high hopes for an HP-owned Palm, saying at the time of the acquisition that he was confident webOS would "reach its full potential" with HP's backing. Perhaps it didn't turn out the way he expected.
AllThingsD is reporting that Rubinstein left the company on Friday with no immediate plays. His exit comes after the fulfillment of a commitment to stay with the technology giant for 12 to 24 months after the acquisition.
"Jon has fulfilled his commitment and we wish him well," HP spokeswoman Mylene Mangalindan said.
Rubinstein said, "I am going to take a well-deserved break after four-and-a-half years of developing webOS."
Rubinstein Unhappy? HP bought Palm for $1.2 billion in April 2010. At the time, Todd Bradley, executive vice president of the Personal Systems Group at HP, said Palm's webOS operating system was the ideal platform to expand HP's mobility strategy and create a unique HP experience that spanned multiple connected devices.
Rubinstein came on board as senior vice president and general manager of the Palm global business unit at HP. He soon rolled out the Palm Pre 2 and webOS 2.0, which offered true multitasking. HP then got out of the mobile handset business and tried its webOS luck with the HP TouchPad, which was a dismal failure.
In July, HP shifted its webOS strategy. HP announced plans to accelerate the global expansion of webOS and moved Rubinstein off the project. HP appointed Stephen DeWitt as senior vice president and general manager of the webOS business unit and shifted Rubinstein over to a product innovation role within the company's Personal Systems Group.
But the ultimate deal breaker for Rubinstein may have been HP's move earlier this...

Scientists probe form, function of mysterious protein
Using computer models and laboratory experiments, scientists have probed the structure of the protein mitoNEET to better understand its role in aging, cancer and diabetes. They found the protein could untangle its arms at one end to loosen its grip on a potentially toxic molecule of iron and sulfur.
