College student Danya Sherman was drugged and sexually assaulted by a classmate. Her response was to create a product that would alert would-be victims of possible drink contamination. The KnoNap is a napkin that can detect the presence of 26 of the 40 date rape drugs on the market. It looks like a regular napkin, but if wet it will alert the person of any chemicals in the liquid by changing colors.

Her goal is to have these at every bar in America. She just won a young entrepreneur contest; the product is receiving funding from GWU and the Halcyon Incubator. She's in talks with manufacturers and plans to launch a kickstarter campaign in the spring.

What’s Not to Love About Lab Grown Meat?
A future of eating meat without ethical or environmental implications is more real than ever before. But will people eat it food grown in a lab?

A future of eating meat without ethical or environmental implications is more real than ever before. While plant-based alternatives are growing in popularity, the real black horse with game-changing potential seems to be actual meat… grown in science labs. The question at this point is not whether this approach is viable or scalable, but simply: will people want to eat it?

These Gloves Can Teach You to Play the Piano. And Maybe Heal Your Brain.
Through "passive haptic learning", these gloves can teach you how to play the piano in an hour. Braille in four hours. Now researchers want to see if victims of traumatic brain injuries can use these gloves to re-learn critical skills.

Georgia Tech researchers Thad Starner and Caitlyn Seim have developed a pair of gloves for playing piano that can magically get you up to speed in just an hour. They've also taught blind people to read braille in four hours, a process that usually takes up to four months. The gloves work through a process called passive haptic learning, and is another great discovery from Georgia Tech researchers. Basically, they vibrate in...

Twenty people die every day in the U.S. waiting for an organ transplant. There aren’t enough organs for the 100,000 people waiting for one. And there likely never will be… unless we can find a better way to source them. Enter: the pigs. A team of scientists has figured out how to grow human organs in pigs. It might make you feel weird. But it also might save countless lives.

A self-professed data nerd, Thomas Hargrove believes everything around us is following a mathematical formula...including murder. Hargrove wanted to find a way to use data to solve cold cases and identify potential serial killers that have gone unnoticed. Armed with public homicide records, he created an algorithm that can spot similar patterns across different cases. Each cluster is given an unique identifier -- what he...
