NASA on Tuesday night successfully launched its experimental asteroid deflecting spacecraft which is set to smash into an asteroid at 15,000 miles per hour and serve as a test run for countering any future doomsday scenario where a large space rock could end up on a collision course with the Earth.

KEY FACTS The Double Asteroid Redirection Test (DART), developed by NASA and the European Space Agency (ESA) launched from California’s Vandenberg Space Force Base at around 10.20 a.m. local time Tuesday, aboard SpaceX’s reusable Falcon 9 rocket.

Sometime in 2022, the DART spacecraft is expected to smash into the asteroid Dimorphos which orbits a larger satellite called Didymos—neither of which pose a threat to Earth at the moment—with the hope of deflecting its course.

Have you seen C/2021 A1 (Leonard) —a.k.a. “Comet Leonard”—yet? Discovered on January 3, 2021 by Greg Leonard, a senior research specialist at Arizona’s Mount Lemmon Observatory, Comet Leonard is potentially going to become an object visible to binocular and even naked eyes. It’s predicted to reach around magnitude 4 or brighter in December 2021 (for the latest, follow it on Twitter).

It will get closest to the Earth to be super-bright on December 12, 2021, but by then it’s going to be fairly low in the sky. So your best chance is to get up early—about 90 minutes before sunrise—during early December and look east.

Arm yourself with either a small telescope or any pair of binoculars to maximize your chances.

A rare 54-page manuscript featuring preliminary calculations for Albert Einstein’s general theory of relativity sold for about $13 million at auction in Paris Tuesday to an unknown buyer — almost four times more than expected.

It was originally anticipated to fetch $3.5 million.

Auction house Christie’s declined to identify the winning bidder to NBC News.

The papers contain handwritten notes by Einstein and his longtime friend and collaborator Michele Besso from between 1913 and 1914, a year before he shared his theory publicly.

The notations are mostly written in ink, with some in pencil by Besso, and aside from a few tears and other defects the pages are in “fine condition for a working scientific manuscript,” according to Christie’s.

Einstein did not typically preserve his early drafts, and it was Besso who saved the 54 pages.

Einstein’s scientific autographs from the pre-1919 era are rare, and the papers are one of only two surviving manuscripts documenting the early stages of his general theory of relativity, Christie’s said.

Finding evidence of life on another planet would be a game-changer. Right now, we cannot predict how common life is in the Universe because we don’t understand what causes that initial spark of life. We only have one data point — our planet. Finding life on another planet within our solar system would illustrate one of two things. Either, life can begin easily enough that it formed twice within the same solar system, or whatever mechanism started life on Earth also somehow started life on Mars (for example, cross-contamination via meteorite). That’s why, in the search for life on Mars, we must make sure we get it right. Recent research published in the Journal of the Geological Society examines how to know if a structure is a fossil or simply a formation that resulted from a physical, non-biological process. Life on Ancient Mars Mars was a very different place four billion years ago. Under a thick atmosphere, a large ocean formed. During this time, Mars may have been temporarily habitable. Eventually, this water was lost to space or locked up in global ice caps. The search for life on Mars, then, is through ancient fossils — microbial evidence that the surface of Mars was inhabitable by microscopic life. Full Story:

Bringing global giants into the economic fight.

The world’s biggest chip-making nation is getting serious.

Japan has committed $5.2 billion (roughly 600 billion yen) toward providing support for semiconductor manufacturers in a bid to help solve the world’s ongoing chip shortage.

While the funds will go to several chipmakers, the most notable among them is the largest one in the world, Taiwan Semiconductor Manufacturing Co (TSMC), according to an initial Tuesday report from Nikkei.

Japan invests $5.2 billion in Taiwan’s giant chip-making firm TSMC also said that it would construct a new chip plant in Japan for $7 billion in a joint effort with Sony Group Corp. Understandably, the government of Japan was pleased. The remaining 200 billion yen of Japan’s new investment will be directed toward preparing other factories for multiple new projects, including one under development by the U.S. memory chipmaker Micron Technology Inc, and Japan’s Kioxia Holdings, according to the report. Japan has remained the largest chip-making industry in the world since the 1980s. But since then the nation has fought an uphill battle to maintain its competitive edge in an increasingly crowded industry, falling into a steady decline in the last three decades as economic rivals like manufacturers based in Taiwan continued to close the gap.

Sooo… the inimitable Russell Brand posted a video a few weeks ago saying some amusing but largeuly inaccurate and misleading things about the Grace humanoid eldercare robot we’re making in our Awakening Health project (http://awakening.health).

Russell’s video is here: https://www.youtube.com/watch?v=SDD7M1OWBDg.

I recorded this video as a sort of response, to set the record straight a bit and explain why Russell is wrong about Grace and what is the actual nature of the Awakening Health project and what are the motivations behind it!

The three main points I make in the video (but with more color and detail, so do watch the video if you’re interested!!) are:

1) Grace is there to help nurses and nursing assistants not replace or obsolete them. When she becomes an AGI she still won’t obsolete the need for human connection and human care. Elderly folks need extra help and attention right now and Grace can help. My grandfather spent the last 5 years or so of his life in an eldercare facility; it was a pretty good one, but he was still lonely and confused a lot of the time and certainly could have benefited greatly from a robot like Grace.

2) Awakening Health is a JV of Hanson Robotics and: SingularityNET (http://singularitynet.io), whose purpose is to democratize & decentralize AI. It’s all about data sovereignty and putting the control over the AI in the hands of the humans who are training and using the AI. Not about centralized tech oppression of the elderly or anyone else as Russell alludes. Actually I think I see very closely eye to eye w/ Russell Brand on the dangers of Big Tech and Big Government, though I probably more clearly see the path to a solution than he does (hint: it has to do with blockchain-meets-beneficial-AGI).

Research led by UT Southwestern and the University of Washington could lead to a wealth of drug targets.

UT Southwestern and University of Washington researchers led an international team that used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein interactions. The study, published in Science, identified more than 100 probable protein complexes for the first time and provided structural models for more than 700 previously uncharacterized ones. Insights into the ways pairs or groups of proteins fit together to carry out cellular processes could lead to a wealth of new drug targets.

“Our results represent a significant advance in the new era in structural biology in which computation plays a fundamental role,” said Qian Cong, Ph.D., Assistant Professor in the Eugene McDermott Center for Human Growth and Development with a secondary appointment in Biophysics.

The findings could inform the design of new materials such as iridescent windows or waterproof textiles.

If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which paper a butterfly’s wings like shingles on a wafer-thin roof. The structure and arrangement of these scales give a butterfly its color and shimmer, and help shield the insect from the elements.

Now, MIT

When we talk about the distance to an object in the expanding Universe, we’re always taking a cosmic snapshot — a sort of “God’s eye view” — of how things are at this particular instant in time: when the light from these distant objects arrives. We know that we’re seeing these objects as they were in the distant past, not as they are today — some 13.8 billion years after the Big Bang — but rather as they were when they emitted the light that arrives today.

But when we talk about, “how far away is this object,” we’re not asking how far away it was from us when it emitted the light we’re now seeing, and we aren’t asking how long the light has been in transit. Instead, we’re asking how far away the object, if we could somehow “freeze” the expansion of the Universe right now, is located from us at this very instant. The farthest observed galaxy GN-z11, emitted its now-arriving light 13.4 billion years ago, and is located some 32 billion light-years away. If we could see all the way back to the instant of the Big Bang, we’d be seeing 46.1 billion light-years away, and if we wanted to know the most distant object whose light hasn’t yet reached us, but will someday, that’s presently a distance of ~61 billion light-years away: the future visibility limit.

Natural selection, the evolutionary process that guides which traits become more common in a population, has been acting on us for the past 3,000 years, right up to the modern day, new research suggests.

And it seems to be acting in surprising ways on complex traits encoded by multiple genes, such as those tied to intelligence, mental illness and even cancer.
