On August 17, 2017, astronomers witnessed an extraordinary celestial event: a collision between two ultra-dense neutron stars. Scientists had never seen anything quite like it, leading to much speculation as to what happened in the wake of the monumental encounter. New research now suggests the collision produced a black hole—but if true, it would be the lightest black hole known to science.

The thought of two neutron stars smashing into each other is nothing short of astounding. Neutron stars are stellar corpses—the remnants supernovae—and they cram a huge amount of mass into a ludicrously small sphere. Typical neutron stars are only as wide as a large city, but they’re about a half million times more massive than Earth, or about two solar masses.

A collision of two neutron stars may seem unlikely, but it happened. Data from the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo interferometer showed that shit got completely wild in the moments leading up to the colossal smash up. For a period of about two minutes, the binary pair spiraled around each other with unimaginable speed, spewing gravitational waves into the cosmic void. Each orbit brought the pair closer together, culminating in a collision that produced a giant shockwave.

Someday, AI robot assistants might be able to make you a coffee after watching you do it.

MIT CSAIL

Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the University of Toronto are teaching AI to do household chore using a Sims inspired virtual simulator. While household chores are dreary, if not particularly complex for humans, for AI, making a cup of coffee or turning on the toaster is a bit more involved. Watching TV from the sofa, for instance, requires an AI to break the task down to specific steps, like: “walk to the TV,” “switch on the TV,” “walk to the sofa,” and “sit on the sofa.”

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all.

The first hints these elusive particles turned up decades ago. But after years of dedicated searches, scientists have been unable to find any other evidence for them, with many experiments contradicting those old results. These new results now leave scientists with two robust experiments that seem to demonstrate the existence of sterile neutrinos, even as other experiments continue to suggest sterile neutrinos don’t exist at all.

That means there’s something strange happening in the universe that is making humanity’s most cutting-edge physics experiments contradict one another. [The 18 Biggest Unsolved Mysteries in Physics].

It’s a philosophy best exemplified by Wood’s book released last month, Transcending Politics: A Technoprogressive Roadmap to a Comprehensively Better Future, which starts by declaring politics “broken,” technology as something that “risks making matters worse,” and deems transhumanism the force that can fix it all “comprehensively”:

David Wood, a transhumanist who co-founded Symbian in 1998, is working to develop a transhumanist superdemocracy that uses the best parts of artificial intelligence and communication to draw on the likes of Zoltan Istvan and Peter Thiel in a new movement to create longevity and sustainable abundance for all.

8 Amazing CRISPR gene editing projects that could change life as we know it.

Since it burst onto the scene a decade ago, CRISPR-Cas9 has shaken the field of genetics to its core. Offering a new genomic editing tool that’s faster, cheaper and more accurate than previous approaches, it opens up an astonishing breadth of possible applications.

From saving lives to potentially rescuing coral reefs, here are eight examples of exciting CRISPR projects that showcase just why this gene-editing tech has everyone talking.

It’s interesting to note that eastern Texas, Louisiana and Arkansas are experiencing much less soil moisture during the middle of May…

Data from the first NASA satellite mission dedicated to measuring the water content of soils is now being used operationally by the U.S. Department of Agriculture (USDA) to monitor global croplands and make commodity forecasts.

The Soil Moisture Active Passive mission, or SMAP, launched in 2015 and has helped map the amount of water in soils worldwide. Now, with tools developed by a team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, SMAP soil moisture data are being incorporated into the Crop Explorer website of the USDA’s Foreign Agricultural Service, which reports on regional droughts, floods and crop forecasts. Crop Explorer is a clearinghouse for global agricultural growing conditions, such as soil moisture, temperature, precipitation, vegetation health and more.

“There’s a lot of need for understanding, monitoring and forecasting crops globally,” said John Bolten, research scientist at Goddard. “SMAP is NASA’s first satellite mission devoted to soil moisture, and this is a very straightforward approach to applying that data.”
