A 1997 Food and Drug Administration (FDA) rule allowed food manufacturers to use ingredients "generally regarded as safe," or GRAS, like vinegar and lots of other things, without needing approval all over again.

Food advocates say the current GRAS process allows substances into the food supply that might pose a health risk. How can safe products be risky?

In the future, new organs will be created from a patient's own stem cells and they will require no waiting lists, no immunosuppressive drugs, and no stickers on drivers licenses making people available for organ donations.

Currently, organ transplantation is "opt in" - you have a choice. A new paper by psychologists examines whether it might be better to have organ donation be opt-out.

How people perceive and taste alcohol depends on genetic factors, and that influences whether they "like" and consume alcoholic beverages, according to a nutritionist
and colleagues at Penn State's College of Agricultural Sciences.

The iPhone 6 is apparently flexible, though that's a not a good thing; people are warping them when they sit down, and people without abnormal strength can simply twist them in their hands.

But that won't always be a design and construction defect. As tech company LG demonstrated this summer with the unveiling of its 18-inch flexible screen, the next generation of roll-up displays is tantalizingly close.

While it is well-known that Americans conserve electricity more than, for example, Canadians, and that CO2 emissions from energy productions have plummeted to 20 year lows without raising prices, an environmental group and scholars from UC Irvine and Stanford University are saying that won't last - they believe that unless people can't afford electricity generated by fossil fuels, expansion of cleaner energy sources, such as wind and solar, will be harmed.

Bereft of expensive subsidies and mandates, solar is not ready and wind never will be. Solar clearly needs more basic research and natural gas, long touted by environmental groups, seems to be the ideal bridge for Americans, since lobbyists for environmental groups make sure nuclear is kept out of circulation. 

Researchers have developed two new anticancer peptide vaccines and two peptide inhibitors as part of a larger peptide immunotherapy effort, according to two studies published in  OncoImmunology. 

Researchers from  at The Ohio State University Comprehensive Cancer Center identify new peptide vaccines and inhibitors that target the HER-3 and IGF-1R receptors. All four agents elicited significant anti-tumor responses in human cancer cell lines and in animal models.
