Ok… which one of y’all is this?
UPDATE 3: The man reportedly told bomb squad that he sustained “radio frequency burns” while working on a “quantum physics generator” in his garage, according to Battalion Chief Steve Martin, the Columbus Division of Fire spokesman, speaking to the Columbus Dispatch.
“We have no reason to believe that he was trying to make anything that would do anyone any harm,” Martin added.
UPDATE 2: Haley Nelson of WSYX-TV reports that a resident was working on a “quantum physics generator” at the home and was burned. The type of burns caused confusion among first responders, prompting a precautionary evacuation of about 40 homes.
One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated, for example, by state-of-the-art free electron lasers emitting X-ray light. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) describe how this could be done in the journal Physical Review C.
During nuclear fusion two atomic nuclei fuse into one new nucleus. In the lab this can be done by particle accelerators, when researchers use fusion reactions to create fast free neutrons for other experiments. On a much larger scale, the idea is to implement controlled fusion of light nuclei to generate power—with the sun acting as the model: its energy is the product of a series of fusion reactions that take place in its interior.
For many years, scientists have been working on strategies for generating power from fusion energy. “On the one hand we are looking at a practically limitless source of power. On the other hand, there are all the many technological hurdles that we want to help surmount through our work,” says Professor Ralf Schützhold, Director of the Department of Theoretical Physics at HZDR, describing the motivation for his research.
Yale and Oxford researchers say exercise is more important to your mental health than your economic status.
COLORADO SPRINGS, CO. — It’s not easy to get into the GPS room. A security cocoon typical of U.S. military installations protects Schriever Air Force Base in Colorado, but the windowless home of the 2nd Space Operations Squadron (2SOPS) lies within the base’s “restricted access area.” A gatehouse, extra vehicle barriers, armed guards, monitored communication channels, and a total ban on smartphones stand between the outside world and the place where the U.S. Air Force operates the GPS satellite constellation.
Inside you’ll find a hallway lined with keypad-controlled doors. Behind each is a room with 10-person teams who fly satellites. The rooms are staffed around the clock. The 2SOP squadron not only runs the constellation that provides global navigation and precise time data to civilian and military users.
“Whether it’s the public or our other military users, they tend to think of space as a magic box that you turn on and everything just works,” says 1st Lt. Morgan Herman, Assistant Weapons & Tactics Flight Commander. “They don’t always realize how actively we have to manage the constellation.”
The personnel changes at Alphabet continue, this time with Mustafa Suleyman — one of the three co-founders of the company’s influential AI lab DeepMind — moving to Google.
Suleyman announced the news on Twitter, saying that after a “wonderful decade” at DeepMind, he would be joining Google to work with the company’s head of AI Jeff Dean and its chief legal officer Kent Walker. The exact details of Suleyman’s new role are unclear but a representative for the company told The Verge it would involve work on AI policy.
The move is notable, though, as it was reported earlier this year that Suleyman had been placed on leave from DeepMind. (DeepMind disputed these reports, saying it was a mutual decision intended to give Suleyman “time out … after 10 hectic years.”) Some speculated that Suleyman’s move was the fallout of reported tensions between DeepMind and Google, as the former struggled to commercialize its technology.
Many of us are drawn to beauty in mathematics. But is that the way nature really works?
A type of artificial intelligence technique is now being used to develop new drugs and therapies and could perhaps even help to solve aging.
An urgent need for aging biomarkers
There has long been an urgent need in our field to develop increasingly accurate biomarkers of aging so that the efficacy of interventions can be gauged. Deep learning is one of the more recent techniques being applied in the search for aging biomarkers.
Life expectancy rose, and so did the number of years we spend without serious health problems, researchers say.
