Ruby that hides 2.5 billion-year-old signs of life is one precious gem

Posted by in categories: biological, materials

If you own any piece of jewelry with a ruby, you’re probably never going to look at it the same way again.

Forget those perfect gemstones you see glittering in store displays. What scientists are looking for are the flawed ones — the ones that contain inclusions which can whisper the secrets of Earth’s distant past, like that tardigrade trapped in amber. When researcher Chris Yakymchuk and his team unearthed a peculiar ruby in Greenland, the inclusion they found was what remained of life that was over 2.5 billion years old.

What was inside the ruby sounds common enough. Graphite is the same material pencils write with, but it is also a pure form of carbon that Yakymchuk determined to be all that was left of prehistoric microbes, possibly the same cyanobacteria (blue-green algae) that first released oxygen into Earth’s atmosphere through photosynthesis. He led a study recently published in Ore Geology Reviews.

Every Prototype that Led to a Realistic Prosthetic Arm

Posted by in categories: biotech/medical, cyborgs, transhumanism

Since the early 2000s, private companies, governments, and research labs have been developing prosthesis that are a lot more advanced than previous designs. WIRED talked with Easton LaChapelle, founder and CEO of Unlimited Tomorrow, to understand how he designed, tested, and adopted his prosthetic arm.

The movie GENERATION IMPACT: THE INVENTOR, follows 25-year old innovator Easton LaChappelle, who developed the world’s lightest weight and most affordable bionic limb. GENERATION IMPACT: THE INVENTOR, can be viewed on HP.com’s digital hub, the Garage (http://hp.com/generation-impact) and YouTube.

First spacewalk by a Chinese female astronaut during Shenzhou 13 crew space station mission

Posted by in category: space travel

The crew of China’s Shenzhou 13 mission completed their first spacewalk of their mission on board the Tiangong space station on November 7, 2021. One of the crew members venturing outside was Wang Yaping who became China’s first female astronaut to complete a spacewalk. She joined Zhai Zhigang for what was the first planned activity of China’s longest space flight yet, a six-month mission during which the crew will focus on station expansion.

Crypto Miners Driving High Demand for AMD CPUs with Big L3 Caches

Posted by in categories: bitcoin, computing, cryptocurrencies, information science

Now that crypto miners and their scalping ilk have succeeded in taking all of our precious GPU stock, it appears they’re now setting their sights on one more thing gamers cherish: the AMD CPU supply. According to a report in the UK’s Bitcoin Press, part of the reason it’s so hard to find a current-gen AMD CPU for sale anywhere is because of a crypto currency named Raptoreum that uses the CPU to mine instead of an ASIC or a GPU. Apparently, its mining is sped up significantly by the large L3 cache embedded in CPUs such as AMD Ryzen, Epyc, and Threadripper.

Raptoreum was designed as an anti-ASIC currency, as they wanted to keep the more expensive hardware solutions off their blockchain since they believed it lowered profits for everyone. To accomplish this they chose the Ghostrider mining algorithm, which is a combination of Cryptonite and x16r algorithms, and thew in some unique code to make it heavily randomized, thus its preference for L3 cache.

In case you weren’t aware, AMD’s high-end CPUs have more cache than their competitors from Intel, making them a hot item for miners of this specific currency. For example, a chip like the Threadripper 3990X has a chonky 256MB of L3 cache, but since that’s a $5,000 CPU, miners are settling for the still-beefy Ryzen chips. A CPU like the Ryzen 5900X has a generous 64MB of L3 cache compared to just 30MB on Intel’s Alder Lake CPUs, and just 16MB on Intel’s 11th-gen chips. Several models of AMD CPUs have this much cache too, not just the flagship silicon, including the previous-gen Ryen 9 3900X CPU. The really affordable models, such as the 5800X, have just 32MB of L3 cache, however.

Snoopy to fly on NASA’s Artemis I mission in one-of-a-kind spacesuit

Posted by in category: space travel

The intrepid space explorer, who in 1969 became the world’s first beagle to land on the lunar surface — at least in the Peanuts comic strips drawn by the late Charles M. Schulz — is set to fly for real aboard NASA’s first Artemis mission in 2022. Snoopy, in plush form, will serve as the “zero-g indicator” on the Artemis I Orion spacecraft as it loops around the moon.

Snoopy made a similar journey more than 50 years ago, flying with “Charlie Brown” as the call signs for the lunar and command modules that flew astronauts on a final dress rehearsal before the first moon landing.

“I will never forget watching the Apollo 10 mission with my dad, who was so incredibly proud to have his characters participate in making space exploration history,” Craig Schulz, son of cartoonist and producer of “The Peanuts Movie,” said in a statement. “I know he would be ecstatic to see Snoopy and NASA join together again to push the boundaries of human experience.”

The Station Crew Welcomed Four New Members

Posted by in category: space travel

Running more than 30 minutes ahead of schedule, the SpaceX Crew-3 astronauts docked to the International Space Station at 6:32 p.m. EST Thursday, Nov. 11, less than 24 hours after launching from the Kennedy Space Center in Florida. NASA astronauts Raja Chari, Tom Marshburn, Kayla Barron, and ESA (European Space Agency) astronaut Matthias Maurer opened the hatch of their Crew Dragon spacecraft Endurance at 8:25 p.m. and participated in a welcome ceremony with their new Expedition 66 crewmates at 9 p.m.

On board to welcome them were fellow astronaut Mark Vande Hei, Expedition 66 Commander Anton Shkaplerov and Flight Engineer Pyotr Dubrov of Roscosmos. Joining the welcome ceremony from Earth were Kathy Lueders, NASA associate administrator for Space Operations, NASA and Josef Aschbacher, ESA director-general.

The newest crew to the microgravity laboratory is the agency’s third crew rotation mission with SpaceX and will remain on board until April 2022 as a part of Expedition 66.
