Of all the laws of physics, this is arguably one of the strangest — scientists have discovered that the forces controlling the behaviour of a black hole’s event horizon are also at play in superfluid helium, an extraordinary liquid that flows without friction.
This entanglement area law has now been observed at both the vast scale of black holes and the atomic scale of cold helium, and could be the key to finally establishing the long sought-after quantum theory of gravity — the solution to one of the deepest problems in theoretical physics today.
The fact that an entanglement area law can apply to both black holes and helium “is weird,” says one of the team, physicist Adrian Del Maestro from the University of Vermont, “and it points to a deeper understanding of reality.”

I can conceive that in saner circumstances, Tesla Model X might never have come to be. But the strongest blades are forged in the hottest fires, and for those that survive the heat, something very special is born.
Model X is special in a way that the automotive industry hasn’t been able to conceive in a very long time. It is an all-electric SUV that can seat up to seven people with bucketloads of cargo space to spare. It is a sporty all-wheel drive car that can throw instant and ungodly amounts of torque at the tarmac. It is a serene cruiser with its silent drive and breathtaking panoramic windshield. It is, in essence, an eight-eyed falcon with a supercomputer brain that dreams of a future of fully autonomous driving. And I had to have it.
As a Model S owner, I had already experienced and enjoyed more than a year of zero emissions Tesla driving. I knew what great things the car was capable of. I’d felt the thrill of instant torque, I’d fallen in love with the one-foot, regenerative braking driving experience, and I’d been chauffeured up and down the M1 by my very own Autopilot. Where the Model S presented itself as an all electric car — a subtle statement and proof of concept about a future of green but powerful motoring, Model X presented itself as a bold vision for what a car could be, if its only blueprint were imagination.

A group of prominent researchers is calling for changes to scientific-research guidelines to address a range of new biological entities created in labs that may share similar characteristics to embryos.
These entities, created through a variety of techniques, have been studied at only the earliest stages of development. In some cases, scientists have taken cells from an embryo and manipulated them to generate another embryo-like…

The cloud is becoming a bigger part of IBM’s business, and the technology giant is expanding its data center offerings.
IBM CEO Ginni Rometty announced at the company’s InterConnect conference in Las Vegas Tuesday a new data center in China, its 51st overall in 20 nations.

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories. “It’s called an entanglement area law,” says Adrian Del Maestro, a physicist at the University of Vermont who co-led the research. That this law appears at both the vast scale of outer space and at the tiny scale of atoms, “is weird,” Del Maestro says, “and it points to a deeper understanding of reality.”

In the future, solar cells can become twice as efficient by employing a few smart little nano-tricks.
Researchers are currently developing the environment-friendly solar cells of the future, which will capture twice as much energy as the cells of today. The trick is to combine two different types of solar cells in order to utilize a much greater portion of the sunlight.
“These are going to be the world’s most efficient and environment-friendly solar cells. There are currently solar cells that are certainly just as efficient, but they are both expensive and toxic. Furthermore, the materials in our solar cells are readily available in large quantities on Earth. That is an important point,” says Professor Bengt Svensson of the Department of Physics at the University of Oslo (UiO) and Centre for Materials Science and Nanotechnology (SMN).
