Researchers at the University of Manchester, UK have made the first autonomous chemically powered synthetic small-molecule motor. The new device, which is very much like the protein motors found in biological cells, might be used to design artificial molecular machines similar to those found in nature. Such machines could be important for applications such as synthetic muscles, nano- and micro-robots and advanced mechanical motors.

[Via Satellite 06–009-2016] NASA has awarded The Aerospace Corporation a grant to investigate the possibility of developing an extremely thin spacecraft that would wrap around debris and remove it from Earth’s orbit. The concept, called Brane Craft, is a 1-square meter spacecraft that is less than half the thickness of a human hair. The Brane Craft would only weigh about 50 grams, significantly less than even a standard CubeSat weight of about 1 kg. The 30-micron-thick spacecraft would have a very high thrust-to-weight ratio, and would be capable of travelling long distances, which opens up other possibilities beyond just the removal of space debris.
“The Brane Craft concept is based on the one-dimensional compression of a complete spacecraft and upper stage into an essentially two-dimensional object in order to maximize power-to-weight and aperture-to-weight ratios,” said Siegfried Janson, Aerospace Corporation’s senior scientist of the microsatellite systems department and the lead investigator on the project.
Elon Musk, the billionaire entrepreneur and founder of Space X, Tesla and Paypal, has told an interviewer there is only a “one in billions” chance that we’re not living in a computer simulation.
Speaking at San Francisco’s Code Conference this week, Musk said that he has had “so many simulation discussions it’s crazy”, and that it got to the point where “every conversation [he had] was the AI/simulation conversation”.
He also claimed that, if we’re not living in a simulation, we could be approaching the end of the world.

The Google team uses a row of nine solid-state qubits, fashioned from cross-shaped films of aluminium about 400 micrometres from tip to tip. These are deposited onto a sapphire surface. The researchers cool the aluminium to 0.02 degrees kelvin, turning the metal into a superconductor with no electrical resistance. Information can then be encoded into the qubits in their superconducting state.
The interactions between neighboring qubits are controlled by ‘logic gates’ that steer the qubits digitally into a state that encodes the solution to a problem. As a demonstration, the researchers instructed their array to simulate a row of magnetic atoms with coupled spin states — a problem thoroughly explored in condensed-matter physics. They could then look at the qubits to determine the lowest-energy collective state of the spins that the atoms represented.
Remember when we played with Google’s Deep Dream neural network to create trippy visuals that featured a whole lot dogs? The creators behind the short film Sunspring do. Instead of Google’s product, however, they turned to a neural network named “Jetson” to do all the heavy lifting. The result? A bizarre nine minutes that you’ll remember for quite some time.
Starring Silicon Valley’s Thomas Middleditch and directed by Oscar Sharp, the short features a special script compiled by the neural network that even wrote a song unique to the film. After being fed scripts like Eternal Sunshine of the Spotless Mind, Watchmen and Aliens (as well as tons of others) it produced a nonsensical mess that actually works quite well in practice. It’s terrible. But then again, it’s so intense it’s entertaining. The film was shot and edited in 48 hours, which is a feat considering how polished it looks in practice.
As one character says “Well, I don’t know anything about any of this, so…” You might get that feeling after viewing the film, but it’s just like watching the insane ramblings of porn stars in Vernon Chatman’s Final Flesh. They’re both eerily similar in tone, though Sunspring is far more incoherent. Check it out for yourself below.
Theoretical physicists have confirmed that it’s not just the information coded into our DNA that shapes who we are — it’s also the way DNA folds itself that controls which genes are expressed inside our bodies.
That’s something biologists have known for years, and they’ve even been able to figure out some of the proteins responsible for folding up DNA. But now a group of physicists have been able to demonstrate for the first time through simulations how this hidden information controls our evolution.
Let’s back up for a second here, because although it’s not necessarily news to many scientists, this second level of DNA information might not be something you’re familiar with.
Ric Edelman is one the top financial advisors in the US. His firm, Edelman Financial Services, has 41 offices across the country. And he thinks, all things constant, most financial advisors as we’ve known them won’t be around much longer.
At Exponential Finance, Edelman said, “I firmly believe that in the next ten years, half of all the financial advisors in this country will be gone.”
Edelman spoke on a panel with fellow advisor, Bill Bachrach, chairman and CEO of Bachrach & Associates.
Facebook launched a feature that allows users to upload photos with 360-degree views on Thursday.
Apart from photos taken from 360-degree cameras, panoramic photos taken on a mobile phone can be converted to a 360-degree view on the newsfeed, the company said on Thursday.
The photos can also be seen in virtual reality compatible devices, Facebook said.
