Article 1: New technology could turn your skin into a touch screen. By Luca Santarelli, The Conversation Technology can be awkward. Our pockets are weighed down with ever-larger smartphones that are a pain to pull out when we’re in a rush. And attempts to make our devices more easily accessible with smart watches have so far fallen flat . But what if a part of your body could become your computer, with a screen on your arm and maybe even a direct link to your brain? Artificial electronic skin (e-skin) could one day make this a possibility. Researchers are developing flexible, bendable and even stretchable electronic circuits that can be applied directly to the skin. As well as turning your skin into a touchscreen, this could also help replace feeling if you’ve suffered burns or problems with your nervous system. The simplest version of this technology is essentially an electronic tattoo. In 2004, researchers in the US and Japan unveiled a pre...
Article 1 : Sweat Detectors? Tiny Sensors Use Perspiration to Track Health Imagine if taking a snapshot of your health were as easy as slapping a sticker on your skin. A new study finds that a tiny adhesive sensor can read what's going on in your body based on your sweat, and relay information about your well-being wirelessly to a smartphone. This type of wearable sensor could work as an alternative to blood tests to assess people's health one day, according to the researchers. Perspiration is a rich chemical full of molecules ranging from simple electrically charged ions to more complex proteins that can shed light on what is happening inside the human body. Doctors can use sweat to diagnose certain diseases, uncover drug use and reveal insight into athletic performance. Sweat also can be gathered far less invasively than blood, said study senior author John Rogers, a materials scientist and director of Northwestern University's Center for Bio-Integrated Electro...
Article n°1: SpaceX Plans to Send 2 Tourists Around Moon in 2018 By KENNETH CHANG SpaceX, the ambitious rocket company headed by Elon Musk , wants to send a couple of tourists around the moon and back to Earth before the end of next year. If they manage that feat, the passengers would be the first humans to venture that far into space in more than 40 years. Mr. Musk made the announcement on Monday in a telephone news conference. He said two private individuals approached the company to see if SpaceX would be willing to send them on a weeklong cruise, which would fly past the surface of the moon — but not land — and continue outward before gravity turned the spacecraft around and brought it back to Earth for a landing. “This would do a long loop around the moon,” Mr. Musk said. The company is aiming to launch this moon mission in late 2018. The two people would spend about a week inside one of SpaceX’s Dragon 2 capsules,...
