Stephen Hawking: Wake Up, Science Deniers! --"Earth is Morphing into Venus" (WATCH Today's 'Galaxy' Stream)

"Venus is like Earth in so many ways," explains Stephen Hawking. "A sort of kissing cousin. She's almost the same size as Earth, a touch closer to the Sun. And, she has an atmosphere that could crush a submarine."

China Ups Ante On Search for Alien Life --Another New Radio Telescope "Will Be Largest Antenna on Earth Able to Trace Origin of Any Signal"  

 

Space-alien-life-777589

 

China will have a new radio telescope to "listen" to the universe that trumps its 500-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope completed in 2016. The Chinese government has approved a plan to build the giant radio telescope in Qitai County, in the far western region of Xinjiang. Chinese scientists claim that the device, named the QTT, will be the world's largest steerable radio telescope.

"Death Rays of the Cosmos" --Past and Future Extinction by Gamma Ray Burst (WATCH Today's 'Galaxy' Stream)

If a gamma ray sweeps over a planet, all complex life could be annihilated. Gamma ray bursts where more common in the past, and could have prevented intelligent life from evolving in the Milky Way (and other galaxies) for billions of years. But they are still occurring, and still a potential life-destroying threat.

Today's Top Science Headline: "Breathtaking!" --Revamped Collider Hunts for New Phenomena Beyond the Standard Model of Physics

The quest to explore the frontiers of physics will heat up next month in Japan, when beams of high-energy electrons are set to start smashing into their antimatter counterparts at one of the world’s premier accelerator laboratories. The experiment, called Belle II, aims to chase down rare, promising hints of new phenomena that would extend the standard model — a remarkably successful but incomplete physics theory that describes matter and forces.

In February, writes Elizabeth Gibney in today's Nature, an accelerator at Japan's High Energy Accelerator Research Organization (KEK) in Tsukuba will begin an initial six-month run of collisions. The eventual goal is to chart in high precision the decays of B-mesons, which contain a fundamental building block of nature known as a b quark (the ‘b’ stands for ‘beauty’ or ‘bottom’).

The work builds on B-meson observations made by experiments including those at the Large Hadron Collider (LHC) at CERN, Europe’s particle-physics laboratory near Geneva, Switzerland. Both efforts are looking for the subtle influence of any new particles or processes on the ways that known particles decay into others. Physicists at the LHC saw some intriguing signs of potential departures from the standard model, most recently in 20171.

LISTEN: Johnson Space Center Radio --"NASA's Search for the Origins of Life in the Universe"

I have built a research lab where we look for organic molecules that we find in meteorites, says Aaron Burton. a planetary scientist NASA's Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center, who seeks to understand how prebiotic chemical reactions could have led to the origins of life. "So these are carbon-containing molecules. And I'm interested in the ones that are related to biology. So things that biology could use. And so by looking at the organic molecules that are found in meteorites, that gives us a way to look at samples where biologically interesting molecules are made but they weren't made by life. They were just made by sort of abiotic chemistry, things that can happen in our solar system.

Today's "Planet Earth Report" Headline --"Bitcoin Miners have Extracted 80 % of All the Bitcoins There Will Ever Be"

 
What-is-bitcoin-story

 

Although bitcoins are bought, sold, and lost more today than ever before, the rate of new bitcoins being created is starting to slow. The reasons behind that are a little complex, but suffice it to say, the closer we get to the 21 million maximum number of bitcoins mined, the harder it gets and we’ve just hit the 80 percent milestone.

Today's Top Science Headline --"World’s Dirt Contains Incredible, Inexhaustible Reservoirs of Undiscovered Antibiotics"

Nobody scours New York's Central Park looking for drugs quite the way Sean Brady does. On a sweltering Thursday, he hops out of a yellow cab, crosses Fifth Avenue, and scurries up a dirt path. Around us, the penetrating churn of a helicopter and the honk of car horns filter through the trees. Brady, a fast-talking chemist in his late 40s who sports a graying buzz cut and rimless glasses, has a wry, self-deprecating humor that belies the single-minded determination of his quest. He walks along restlessly. Near the lake, we head up a rock slope and into a secluded area. Brady bends over and picks up a pinch of dusty soil.

The Alien Observatory --"The Vast Majority of Fossils Discovered in the Universe Will Be Extinct Microbial Life, Not Dinosaurs or Humanoids"

"One intriguing prediction of the Gaian Bottleneck model is that the vast majority of fossils in the universe will be from extinct microbial life, not from multicellular species such as dinosaurs or humanoids that take billions of years to evolve," said Charles Lineweaver at Australian National University (ANU).
