A dark web ties the universe together. Now, we can see it.
How dark is the cosmic web?

They beat us at chess and trivia, supplant jobs by the thousands, and are about to be let loose on highways and roads as chauffeurs and couriers.
Now, fresh signs of robot supremacy are emerging on Wall Street in the form of machine stock analysts that make more profitable investment choices than humans. At least, that’s the upshot of one of the first studies of the subject, whose preliminary results were released in January.
Buy recommendations peddled by robo-analysts, which supposedly mimic what traditional equity research departments do but faster and at lower costs, outperform those of their flesh-and-blood counterparts over the long run, according to Indiana University professors.
It has taken until the second decade of the 21st century, but the U.S. government has finally designated space to be a legitimate domain of military operations and has stood up the U.S. Space Force — that’s the good news. The not-so-good news is that the U.S. Space Force has no routine, reliable access to space.
The Space Force will operate in the near-Earth and cislunar domains like our current military operates in the domains of land, sea, and air. The Army and Marines have their land and air vehicles, the Navy has its surface ships and submarines, and the Air Force has its airplanes. But the assets being transferred to the Space Force — satellites and expendable launch vehicles — are akin to lighthouses, buoys, dirigibles, and coastal artillery because we have so far only treated space as a support service.
The U.S. Space Force must acquire responsive, routine, and reliable access to space — starting with launch systems optimize for reaching low Earth orbit (LEO). The Space Force must be equipped with a fleet of responsive, spacefaring vehicles under the operational purview of the Space Force’s equivalent of an Air Force colonel or Navy captain. Currently, the resource requirements for space launch are so large that only a three-star general of above to approve a mission; for launch to be truly operationally responsive, the required resources — and decision-making authority — must be driven down to a level comparable to what’s been required to send a B-2 Stealth Bomber or the now-retired SR-71 reconnaissance aircraft aloft.

DNA testing companies are starting to profit from selling our data on to big pharma. Perhaps they should be paying us, says science writer Laura Spinney.
Fighting a species-level threat like Covid-19 requires the best brains from disciplines as varied as chemistry, AI, sociology and psychology.
It seems like there’s nothing Elon Musk can’t do.
As CEO of SpaceX and Tesla, founder of The Boring Company, and cofounder of OpenAI and Neuralink, Musk seems to be everywhere all at once, pushing all kinds of futuristic technologies. He’s said he won’t be happy until we’ve escaped Earth and colonized Mars.
Between space rockets, electric cars, solar batteries, and the billions he’s made along the way, Musk is basically a real-life Tony Stark — which is why he served as an inspiration for Marvel’s 2008 “Iron Man” film.
But people’s “digital afterlives” extend far beyond Facebook. When a 21st century citizen dies, they often leave behind a trove of posts, private messages, and personal information on everything from Twitter to online bank records. Who owns this data, and whose responsibility is it to protect the privacy of the deceased? Faheem Hussain, a social scientist at Arizona State University in Tempe, has spent the past few years peering into the murky waters of how people, platforms, and governments manage the digital lives we leave behind.
Hussain gave a presentation on our digital legacies today at the annual meeting of the American Association for the Advancement of Science (AAAS), which publishes Science. We caught up with Hussain to talk about why online platforms should encourage people to plan ahead for their imminent deaths, whether you have a right to privacy after you die, and the strange new culture of digital mourning.
Space junk is a growing problem. For decades we have been sending satellites into orbit around Earth. Some of them de-orbit and burn up in Earth’s atmosphere, or crash into the surface. But most of the stuff we send into orbit is still up there.
This is becoming an acute problem as years go by and we launch more and more hardware into orbit. Since the very first satellite—Sputnik 1—was launched into orbit in 1957, over 8000 satellites have ben placed in orbit. As of 2018, an estimated 4900 are still in orbit. About 3000 of those are not operational. They’re space junk. The risk of collision is growing, and scientists are working on solutions. The problem will compound itself over time, as collisions between objects create more pieces of debris that have to be dealt with.
