70 percent to the author and 30 percent to the distributor The Perseus Books Group has created a distribution and marketing service that will allow authors to self-publish their own e-books, the company said on Sunday. The new service will give authors an alternative to other self-publishing services and a favorable revenue split that is

Device could improve wireless communications systems During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That’s because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour). Now, University of Minnesota engineering researchers have developed a chip on which both sound wave

He predicted that the first wave of robots would most likely become “the body for people with physical disabilities.” MENLO PARK, Calif. — Millions of people watched a robot descend last week on Mars, about 154 million miles away, while it shared video, photos and status updates from its own Twitter account. I had my own encounter

The days of using a plastic card to prove your identity are numbered, as advances in security technology are making it increasingly easy to identify a person using only biometric information. Now, a new smartphone accessory promises to put the power of biometric security in the hands of anyone with an iPhone. The AOptix Stratus allows you to

Every year, millions of people come into emergency rooms complaining of chest pains, yet those pains are only sometimes due to heart attacks. Unfortunately in many of those cases, the only way to be sure of what’s going on is to admit the patient for an overnight stay, and administer time-consuming and costly tests. Now,

Communication in human dialogue is based on one another’s words and body language. We can sense whether the other person is distracted, and we change the course of our conversation and our actions to regain their attention. Most existing robots, however, still use monologue mechanisms, even when engaging in dialogue with a person. For example,

Gel suppresses scarring, creates scaffolding for new neurons and blood vessels A new stroke-healing gel created by UCLA researchers helped regrow neurons and blood vessels in mice whose brains had been damaged by strokes. The finding is reported May 21 in Nature Materials. “We tested this in laboratory mice to determine if it would repair the brain

  The new theory connects quantum entanglement with Einstein’s general relativity Wormholes and entanglement—two of science fiction’s favorite concepts from modern physics—may in reality be two sides of the same coin, physicists say. The findings may offer a way to solve puzzling mysteries about black holes and perhaps help reconcile theories of gravity and quantum physics, which has

How chewing gum or a shed hair can let strangers read your ‘Book of Life’ Someone finds that piece of chewing gum you pitched today, uses the saliva to sequence your DNA and surreptitiously reads your book of life — including genetic secrets like your susceptibility to diseases. If that scenario, posed in an article
