Facebook plans to use solar-powered drones to extend internet access to remote parts of the planet.

So far the system can be used to receive signals carrying data at rates of up to 2.1 gigabits per second, though the team claims it could go faster if it were built to absorb infrared, rather than blue, light.
It’s worth pointing out that this isn’t the first piece of hardware to emerge from the Connectivity Lab. Famously, it’s been working on a solar-powered drone to deliver Internet access. That particular project is progressing slowly, though, so despite the fact that the team behind the new laser device plans to test it in a real-world setting, there’s likely still much development ahead before it’s used widely.
The social network is, however, busy pursuing plenty of other projects to take data to the sticks. Most notably, its Telecom Infra Project will use open-source cellular networks to achieve similar results. That way, you see, anyone will be able to sign up on Facebook.

Have you wondered how Facebook might offer high-speed internet access using lasers? The company’s Connectivity Lab is happy to show you. It just published a research paper explaining laser beam technology can deliver up to 2Gbps to remote places. The trick, it says, is to use fluorescent optical fibers to collect the light instead of relying on traditional optics. Since the fibers don’t emit the same color that they’re absorbing, you can shine a brighter light at them (similar to a solar concentrator) and manage an extremely quick turnaround time of under 2 nanoseconds. Combine that with multi-stream data encoding and you get the ample bandwidth that’s normally reserved for WiFi and wired networks.
Facebook says it’s “investigating the feasibility” of shipping laser internet hardware based on this technology, but that may be more realistic than you think. The social network managed this feat using readily available materials that weren’t even meant for the purpose. It’s hoping that other organizations will craft optimized materials that are better-suited, and notes that an infrared-based system might hit speeds of up to 10Gbps. As important as Facebook’s findings might be, they’re only just the beginning.
Google announced on Wednesday that it has been using a DeepMind-built AI system to control certain parts of its power-hungry data centres over the last few months as it looks to make its vast server farms more environmentally friendly.
Last year, a Greenpeace report predicted that the electricity consumption of data centres is set to account for 12% of global electricity consumption by 2017 and companies like Google, Amazon, Facebook and Apple have some of the biggest data centres in the world.
Google said it has been able to reduce the energy consumption of its data centre cooling units — used to stop Google’s self-built servers from overheating — by as much as 40% with the help of a DeepMind AI system.

It was 47 years ago that NASA won the space race against the Soviet Union, and Apollo 11 astronauts first walked on the Moon.
And now American companies have pitched a series of new plans that would see the country finally return to the lunar surface… this time, alongside the Russians.
The collaboration between the two countries isn’t entirely surprising — Russia and America have been working together in space since their association on the International Space Station (ISS) first began in 1993.

The team is now embarking on its most ambitious project yet, a wide-reaching virtual reality network called Project Sansar that is, in many ways, aiming to become a new layer of reality that gives individuals and businesses a space to experiment with VR environments for their first time.
I had the chance to sit down for a demo of Sansar with Linden Lab CEO Ebbe Altberg this past week and take an early look into some of the platform’s first environments.
Traversing the worlds of Sansar and chatting with my guide, Linden Lab VP of Product Bjorn Laurin, was a mostly seamless experience but still an oddly unsettling one. It’s not that anything was particularly creepy about the place I was viewing through an Oculus Rift headset. Sansar is visually placid and often beautiful, but it’s also startlingly scalable and boundless. Scale is something that’s often taken for granted in an age of video game epics like Skyrim and GTAV, but when every horizon you see through your own point-of-view is conquerable, you’re left to either feel very bold or very lost.

Grace LeClair had just finished eating dinner with friends when she got the phone call every parent dreads. The chaplain at the Medical College of Virginia was on the other end. “Your daughter has been in a serious accident. You should come to Richmond right away.” LeClair was in Virginia Beach at the time, a two-hour drive from 20-year-old Bess-Lyn, who was now lying in a coma in a Richmond hospital bed.
The friend who was with Bess-Lyn has since filled in the details of that day in March. The two women were bicycling down a steep hill, headed toward a busy intersection, when Bess-Lyn yelled that her brakes weren’t working and she couldn’t slow down. Her friend screamed for her to turn into an alley just before the intersection. But Bess-Lyn didn’t turn sharply enough and crashed, headfirst, into a concrete wall. She wasn’t wearing a helmet. By the time the ambulance reached the hospital, Bess-Lyn was officially counted among the 1.5 million Americans who will suffer a traumatic brain injury (TBI) this year.
Bess-Lyn’s mom was halfway to Richmond when she received a second call, this time from a doctor. “He was telling me that she had a very serious injury, that she had to have surgery to save her life and that if I would give permission, they would use this experimental, not-approved-by-the-FDA drug,” Grace LeClair recalls. “He said that it would increase the oxygen supply to her brain. To me that only made sense, so I said yes.”
Storage tech doesn’t get much better than this. Scientists at TU Delft have developed a technique that uses chlorine atom positions as data bits, letting the team fit 1KB of information into an area just 100 nanometers wide. That may not sound like much, but it amounts to a whopping 62.5TB per square inch — about 500 times denser than the best hard drives. The scientists coded their data by using a scanning tunneling microscope to shuffle the chlorine atoms around a surface of copper atoms, creating data blocks where QR code -style markers indicate both their location and whether or not they’re in good condition.
Not surprisingly, the technology isn’t quite ready for prime time. At the moment, this storage only works in extremely clean conditions, and then only in extreme cold (77 kelvin, or −321F). However, the approach can easily scale to large data sizes, even if the copper is flawed. Researchers suspect that it’s just a matter of time before their storage works in normal conditions. If and when it does, you could see gigantic capacities even in the smallest devices you own — your phone could hold dozens of terabytes in a single chip.

A new paper asserts that a physical body might be able to pass through a wormhole in spite of the extreme tidal forces that are at play.
A physical object, such as a person or a spacecraft, could theoretically make it through a wormhole in the centre of a black hole, and maybe even access another universe on the other side, physicists have suggested.
