Nuclear DNA From Cave Sediments Helps Unlock Ancient Human History

Posted by in categories: biotech/medical, genetics

For the first time, scientists have succeeded in extracting and analyzing Neandertal chromosomal DNA preserved in cave sediments.

The field of ancient DNA has revealed important aspects of our evolutionary past, including our relationships with our distant cousins, Denisovans, and Neandertals. These studies have relied on DNA from bones and teeth, which store DNA and protect it from the environment. But such skeletal remains are exceedingly rare, leaving large parts of human history inaccessible to genetic analysis.

To fill these gaps, researchers at the Max Planck Institute for Evolutionary Anthropology developed new methods for enriching and analyzing human nuclear DNA from sediments, which are abundant at almost every archaeological site. Until now, only mitochondrial DNA has been recovered from archaeological sediments, but this is of limited value for studying population relationships. The advent of nuclear DNA analyses of sediments provides new opportunities to investigate the deep human past.

TSMC Uses AMD’s EPYC Chips to Make Chips

Posted by in categories: business, robotics/AI

The silicon Ouroboros.


TSMC produces chips for AMD, but it also now uses AMD’s processors to control the equipment that it uses to make chips for AMD (and other clients too). Sounds like a weird circulation of silicon, but that’s exactly what happens behind the scenes at the world’s largest third-party foundry.

There are hundreds of companies that use AMD EPYC-based machines for their important workloads, sometimes business-critical workloads. Yet, when it comes to mission-critical work, Intel Xeon (and even Intel Itanium and mainframes) rule the world. Luckily for AMD, things have begun to change, and TSMC has announced that it is now using EPYC-based servers for its mission-critical fab control operations.

Why A.I. research may be going down a dead end

Posted by in category: robotics/AI

Seems very biased, but worth a glance.


“Misfired” neurons might be a brain feature, not a bug — and that’s something AI research can’t take into account.

Intel Core i5-11400 Review: Unseating Ryzen’s Budget Gaming Dominance

Posted by in category: computing

Intel exploits the obvious hole in the Ryzen product stack.


Our encoding tests include benchmarks that respond best to single-threaded performance, like the quintessential LAME and FLAC examples, but the SVT-AV1 and SVT-HEVC tests represent a newer class of threaded encoders.

Intel’s Core i5-11400 takes the lead over its similarly-priced competitors in the LAME benchmark, while we see a near-tie across the board in FLAC. We see larger gains for the 11400 in the threaded SVT-AV1 and HEVC encoder tests, but only after we lifted the power limits and used a more powerful cooler.

Take a look inside Astra’s rocket factory, as the company prepares to go public

Posted by in categories: business, space

ALAMEDA, California — Rocket builder Astra wants to simplify the launch business, with the soon-to-be-public company on a quest to both cut manufacturing costs while dramatically increasing the number of launches to a daily rate.

Astra is preparing to go public by the end of June through a merger with SPAC Holicity, in a deal that will infuse as much as $500 million capital into the company. In the meantime, Astra is expanding its headquarters on the San Francisco Bay while the company prepares for its next launch this summer.

A SPAC, or special purpose acquisition company, raises capital in an initial public offering and uses the proceeds to buy a private firm and take it public.

Neuralink President Max Hodak tweeted Saturday that he has left the company he co-founded with Tesla and SpaceX CEO Elon Musk. Hodak didn’t elaborate on why he left the company or elaborate on the circumstance for his departure. “I am no longer at Neuralink (as of a few weeks ago),” he tweeted. “I learned a ton there and remain a huge cheerleader for the company! Onward to new things.”

“For those of you enrolled in our frequent flyer program, you’ve earned 68 million miles on this voyage,” SpaceX’s Mission Control radioed.


CAPE CANAVERAL, Fla. — SpaceX safely returned four astronauts from the International Space Station on Sunday, making the first U.S. crew splashdown in darkness since the Apollo 8 moonshot.

The Dragon capsule parachuted into the Gulf of Mexico off the coast of Panama City, Florida, just before 3 a.m., ending the second astronaut flight for Elon Musk’s company.
