How to build a real time machine

Science
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.Ron Mallett has a dream: He wants to travel in time.This isn't mere fantasy - Mallett is a respected professor of physics."I think of myself as being an ordinary person with a passion, and my passion is the possibility of time travel," he says.Prof Mallett has wanted to build a time machine for most of his life. His passion, he explains, can be traced to a tragic event early in his life.Ron's father, a heavy smoker, died of a heart attack at the age of 33 - when Prof Mallett was just 10 years of age. Ron was deva...
Crow vending machine skills 'redefine intelligence'

Crow vending machine skills 'redefine intelligence'

Science
Media playback is unsupported on your device A small South Pacific island is home to a crow with remarkable abilities that have scientists hooked. New Caledonian crows make and use tools - including a kind of fishing hook. They can solve complex problems and have even been recorded capturing grubs by repeatedly poking them with a stick until they are so agitated, they bite.Now, an experiment using a vending machine specifically designed for crows has revealed something about how intelligence evolves. The "vending experiment" is the latest in an ongoing investigation into these birds' abilities. They are so remarkable that scientists have a special aviary in New Caledonia, where they can keep wild birds for only a few days and test their proble...
Machine learning can predict low blood pressure during surgery

Machine learning can predict low blood pressure during surgery

Health
June 11 (UPI) -- A new algorithm can predict potentially dangerous low blood pressure during surgery. Researchers have developed machine learning than can identify hypotension as much as 15 minutes before it occurs, and are correct about 84 percent of the time. The findings were published Monday in the journal Anesthesiology. "Physicians haven't had a way to predict hypotension during surgery, so they have to be reactive, and treat it immediately without any prior warning," Dr. Maxime Cannesson, a professor of anesthesiology at UCLA Medical Center in Los Angeles, said in a press release. "Being able to predict hypotension would allow physicians to be proactive instead of reactive." Canesson said the tool can save lives -- even with a warning only 10 to 15 minutes ahead of time. "By findi...
Hedge funds embrace machine learning—up to a point

Hedge funds embrace machine learning—up to a point

Finance
ARTIFICIAL intelligence (AI) has already changed some activities, including parts of finance like fraud prevention, but not yet fund management and stock-picking. That seems odd: machine learning, a subset of AI that excels at finding patterns and making predictions using reams of data, looks like an ideal tool for the business. Yet well-established “quant” hedge funds in London or New York are often sniffy about its potential. In San Francisco, however, where machine learning is so much part of the furniture the term features unexplained on roadside billboards, a cluster of upstart hedge funds has sprung up in order to exploit these techniques.These new hedgies are modest enough to concede some of their competitors’ points.

Search on for personal flying machine

Technology
The search is on for a mass market personal flying machine, with a $ 2m (£1.4m) competition to "make the dream of personal flight [a] reality".Sponsored by Boeing and run by start-up GoFly, the competition will encourage teams from around the world to come up with designs.Entries must be capable of carrying a person 20 miles without refuelling or recharging, with a vertical or near vertical take-off and landing.A "fly-off" will take place in 2019.GoFly founder Gwen Lighter told the BBC: "I was one of those kids who was always making crazy contraptions and throwing themselves out of trees."I, like millions of people around the globe, always dreamed of flying, and I began to realise that we were seeing a moment of convergence of technologies and were at a point in history when these personal
