1.) It’s now possible that we may be seeing the end of gray hair. According to a study in a medical journal on experimental biology, scientists at the University of Bradford in England have figured out a definitive way to reverse the gray hair process. A hair turns gray when there's a massive accumulation of hydrogen peroxide in the hair follicle. It basically makes the hair bleach itself. So the researchers created a topical solution for your hair that stops it from going gray, and even gets it back to its original color. It's not a dye – they claim it literally fixes your hair follicles and restores their color. But, there’s no word on when it will come available.
2.) There’s going to be a new use for drones in South Africa beginning this summer. Thirsty music fans at the OppiKoppi Music Festival will be able to order beer and have their cold beverage instantly delivered to them via drones. Festival attendees can place orders on their phones. The beer-equipped drones will swoop down and deliver beer via parachute to the appropriate customer. The organizers say the beer drones are now hand-guided, but in the future they'll fly on a GPS grid.
3.) If you want to get someone to respond to your e-mail use pessimistic and negative words. A new study by a software company examined 100 million e-mail messages and identified negative words like "stupid" and "missed" and positive ones, like "amazing". 64% of the messages that used negative words got a response on the same day. Only 47% of more positive emails got a response that quickly. The researchers said there might be a couple reasons why: First, if someone is emailing about an emergency, they're more likely to use negative language. Secondly, people who use negative words are probably more judgmental and impatient, and are more likely to get angry if you don't get back to them. So they get a faster response.
