The video of the green meteor might be the only one taken.

China livestreamed footage of its new manned submersible parked at the bottom of the Mariana Trench on Friday, part of a historic mission into the deepest underwater valley on the planet.

The “Fendouzhe”, or “Striver”, descended more than 10,000 metres (about 33,000 feet) into the submarine trench in the western Pacific Ocean with three researchers on board, state broadcaster CCTV said.

XTI Aircraft has teamed up with VerdeGo Aero to build the TriFan 200, an unmanned, autonomous vertical take-off and landing (VTOL) aircraft.

Denver, Colorado-based XTI and Florida-headquartered VerdeGo say on 19 November that the TriFan 200, a small brother of the in-development passenger TriFan 600 aircraft, will be capable of transporting 227kg (500lb) of cargo on missions of more than 200nm (108km).

“The TriFan 200 aircraft will open up a significant new market for XTI to address the needs of cargo and logistics operators globally,” says XTI’s chief executive Robert LaBelle.

Pharmaceutical companies Pfizer and partner BioNTech will seek emergency government approval for their coronavirus vaccine on Friday, Health and Human Services Secretary Alex Azar said, paving the way for millions of doses to be distributed within 24 hours.

“We will ship millions of doses of vaccine within 24 hours of FDA approval. So my message is hope and help are on the way,” Azar said Thursday as he announced the pending emergency use application during a White House coronavirus task force briefing.

Pfizer’s German partner BioNTech had said this week that it would seek the emergency approval for the vaccine, which showed 94.5 percent efficacy in clinical trials.

Why do certain materials emit electrons with a very specific energy? This has been a mystery for decades — scientists at TU Wien have found an answer.

It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called “photoelectrons.” In materials research, so-called “Auger electrons” also play an important role — they can be emitted by atoms if an electron is first removed from one of the inner electron shells. But now scientists at TU Wien (Vienna) have succeeded in explaining a completely different type of electron emission, which can occur in carbon materials such as graphite. This electron emission had been known for about 50 years, but its cause was still unclear.

Strange electrons without explanation.

A device demonstrated in a groundbreaking new experiment acts like a laser, only backwards. And someday it might send power invisibly through the air.

Subramanian Sundaram, a biological engineer affiliated with both Boston University and Harvard has been looking into the current state of robot hands and proposed ideas regarding where new research might be heading. He has published a Perspective piece in the journal Science outlining the current state of robotic hand engineering.

By almost any measure, robot hand design has evolved into sophisticated territory—robot hands can not only pick things up and let them go, they can sometimes “feel” things and respond in human-like ways—and in many cases, do it with extreme dexterity. Unfortunately, despite substantial inroads to giving robot hands human-like abilities, they still fall far short. Sundaram notes that one area where they need major improvement is in sensing things the way humans do, namely: feeling pressure, temperature and that hard-to-classify sense, pleasure. You cannot tickle a robot hand, for example, and expect a human-like response. Sundaram explains in great detail what is known about the human hand and how it processes sensations, and suggests that robot analogs might possible. He notes that not everything about a robot hand needs to be done in the same way as the human hand.
