Very cool.

A research group from Bar-Ilan University, in collaboration with French colleagues at CNRS Grenoble, has developed a unique experiment to detect quantum events in ultra-thin films. This novel research, to be published in the scientific journal Nature Communications, enhances the understanding of basic phenomena that occur in nano-sized systems close to absolute zero temperature.

Transitions, Phases and Critical Points

A phase transition is a general term for physical phenomena wherein a system transits from one state to another as a result of changing the . Everyday examples are the transition from ice to water (solid to liquid) at zero degrees centigrade, and from water to vapor (liquid to gas) at 100 degrees.

Luminescent solar concentrators (LSCs), which are flat panes of mostly transparent material that take sunlight (both diffuse and directed) and concentrate it at the panes’ edges, can be used as “photovoltaic windows,” which, as the name makes clear, collect solar energy while serving as ordinary windows. Now, researchers at the Università degli Studi di Milano-Bicocca and Glass to Power Srl (both of Milano, Italy) and the University of Minnesota (Minneapolis, MN) are lowering the potential cost of such windows by using silicon nanoparticles as the fluorescent absorber/emitter in the LSC windows.

Three of the planets fall within a temperature range that should allow water to exist on their surfaces – a placement that is sometimes referred to as “the Goldilocks zone” because it is neither too hot nor too cold. Given the right sort of atmosphere, water could also be present on three of the others.

Astronomers say a solar system 39 light-years from Earth’s harbours seven Earth-sized planets, at least three of which are in the temperature sweet spot where water (and potentially life) is possible.

Well I for one would be in the 6%.

A new survey has found that only 6% of respondents would be happy to live in a proposed Equatorial Low Earth Orbit (ELEO) settlement, where humans live in a small cruise ship-like space station at a similar orbit to the ISS.

Four conditions were set for respondents to assess and while at least 30% said they agree with at least one of them, the number shrank significantly when it came to those who could accept all the conditions.

These were that the settlement itself would require permanent residence, would be no bigger than a large cruise ship, would contain no more than 500 people and would require residents to be willing to devote at least 75% of their wealth to move in.

It’s a trap(PIST-1)! 😉

“The seven exoplanets were all found in tight formation around an ultracool dwarf star called TRAPPIST-1.”

Astronomers have found at least seven Earth-sized planets orbiting the same star 40 light-years away, according to a study published Wednesday in the journal Nature. The findings were also announced at a news conference at NASA Headquarters in Washington.

This discovery outside of our solar system is rare because the planets have the winning combination of being similar in size to Earth and being all temperate, meaning they could have water on their surfaces and potentially support life.

“This is the first time that so many planets of this kind are found around the same star,” said Michaël Gillon, lead study author and astronomer at the University of Liège in Belgium.

Almost two months to the day after Uber loaded its fleet of self-driving SUVs into the trailer of a self-driving truck and stormed off to Arizona in a self-driving huff, the company is preparing to launch its second experiment (if you don’t count the aborted San Francisco pilot) in autonomous ride-hailing.

What’s different is that this time, Uber has the blessing from Arizona’s top politician, Governor Doug Ducey, a Republican, who is expected to be “Rider Zero” on an autonomous trip along with Anthony Levandowski, VP of Uber’s Advanced Technologies Group. The Arizona pilot comes after California’s Department of Motor Vehicles revoked the registration of Uber’s 16 self-driving cars because the company refused to apply for the appropriate permits for testing autonomous cars.
