Hawking's final science study released

Science
Stephen Hawking's final scientific paper has been released, and it deals with one of the central topics in the physicist's 56-year-long career.The work was completed in the days before Hawking's death in March.It tackles the question of whether black holes preserve information on the stuff that falls into them.Some researchers had believed this information was destroyed, but others said that this violated the laws of quantum mechanics.These laws propose that everything in our world can be broken down into information, for example, a string of 1s and 0s. In addition, this information should never disappear, not even if it gets sucked into a black hole.But Hawking, building on the work of Albert Einstein, showed that black holes ha...
The festivals mixing music and science

The festivals mixing music and science

Science
Music festivals are increasingly becoming a venue for science as well as bands. Are music and science a good mix?"It's changed my life," says Andrea Sella, who is professor of chemistry at University College London."I couldn't believe that I'd found myself at Latitude in front of about 1,000 people talking about carbon dioxide, dry ice and climate change," he says of his first involvement in scientific outreach at a music festival seven years ago."I thought, 'Oh my God, they started laughing. Let me remember what I did to cause it.'"It's changed the way I teach and speak to students. I've been able to take more risks. I've learnt enormous amounts about the craft of speaking in public." Prof Sella, who won the Royal Society Michael Faraday Prize in 2015 fo...

The Meg: the myth, the legend (the science)

Science
The Meg, Hollywood's latest shark tale, is opening wide this week in anticipation of summer audiences in the mood for a scare.Proposing that the extinct Megalodon, a large prehistoric relative of the great white shark, has survived to the present day, the film follows its subsequent encounter with humanity.But how much do we really know about the giant predator?And what impact do shark attack films have on their real subjects?Shark researcher and Megalodon expert Catalina Pimiento from Swansea University wants to break down a few myths. Dead or alive?"It's very much extinct," says Dr Pimiento. "There's no way it can be still around."Researchers have pinned the date of Megalodon's extinction at ab...
Fastest manmade spinning object to aid quantum mechanics science

Fastest manmade spinning object to aid quantum mechanics science

Science
July 20 (UPI) -- The creators of the world's fastest manmade rotor believe their invention will boost the study of quantum mechanism, the branch of physic devoted to the behavior of subatomic particles. The new rotor can spin at a rate of 60 billion revolutions per minute. Most airplane turbines top out at 3,000 revolutions per minute. Scientists described their impressive new device this week in the journal Physical Review Letters. "This study has many applications, including material science," Tongcang Li, an assistant professor of physics and astronomy at Purdue University, said in a news release. "We can study the extreme conditions different materials can survive in." The rotor is composed of a tiny silica dumbbell. Scientists used a laser to levitate the dumbbell inside a vacuum. T...
How a spider jumps on its prey – science has the answer

How a spider jumps on its prey – science has the answer

Science
Scientists have trained a spider to jump on demand.The diminutive arachnid, which they nicknamed Kim, can leap six times her body length from a standing start.Humans only manage about 1.5 body lengths.Unlocking the secrets of her extraordinary leaps could help build a new generation of robots inspired by nature, say University of Manchester researchers.The regal jumping spider (Phidippus regius) is known for its ability to make precision leaps to pounce on prey, including insects and small invertebrates.It is one of thousands of jumping spiders that are found worldwide and hunt actively rather than catching prey in a web. They have excellent vision, with four large eyes in front and four smaller eyes on the top of their head.The research team filmed the jumping arachnid with high-tech cam...
