“Continents are sort of like icebergs,” says study author Keith Klepeis, a structural geologist at the University of Vermont. “What you see at the surface is not really the full extent of the beast.”

The discovery, described in the journal Geology, may help solve a riddle that’s long perplexed scientists. Most continents contain a core of rock known as a craton, a sort of geologic nucleus at least a billion years old that acts like a stable base upon which continents build. Until now, though, the oldest continental crust found on Zealandia was dated to roughly 500 million years ago—relatively youthful in geologic terms. So if Zealandia is a continent, why did its craton seem to be missing?

This newfound fragment of ancient rock may be part of the missing piece for Zealandia. The discovery “ticks the final box,” Turnbull says. “We are sitting on a continent.”

The renowned Mexican architect Miguel Ángel Aragonés presented ten years of research materialized in his most recent project entitled “Casa PI” whose acronym translates to a new “intelligent prefabricated” construction project. Patented in Switzerland, this system seeks to break the housing paradigm from an integral design that combines the structure of the house with the furniture and new automation technologies in architecture.

The origin of this innovation stems from the idea of creating a modular constructive system that was sustainable, in high quality, that would accelerate construction times, improve acoustic and thermal performance, as well as reduce construction costs and waste. It is based on implementing the technology, we currently live every day with, in an integral design (since conventional homes have had to adapt to these advances through facilities that hinder the design). However, “Casa PI” seeks to start from scratch by serving as a pavilion that shows the advances of this specific moment in history by offering a “piece of furniture to live in” that consumes as little energy as possible.

Making deepfakes is getting easier, and they’re more convincing than ever. Cybercriminals are using video and audio deepfakes to extort money from victims by adding a credible “fake authenticity” to their scams.

Ever since the first person said “the camera never lies,” there have been people out to prove otherwise. Creative photographers in the late 19th century used simple tricks to create faked images.

Using high-powered imaging, the researchers were able to see, for the first time, that immune cells called microglia were not just removing damaged material after experimental seizures but actually appeared to be healing damaged neurons.

Summary: Microglia do not only remove damaged materials following a seizure, they also appear to heal damaged neurons.

Blue Origin is set to launch the New Glenn rocket to orbit. Here’s what you need to know about it.

Summary: A novel helmet that generates a noninvasive oscillating magnetic field was able to reduce tumor mass by 31% in a glioblastoma brain cancer patient.

Source: Houston Methodist.

Houston Methodist Neurological Institute researchers from the department of neurosurgery shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment.

According to the UCS report, however, sodium-cooled fast reactors such as Natrium would likely be less uranium-efficient and would not reduce the amount of waste that requires long-term isolation. They also could experience safety problems that are not an issue for light-water reactors. Sodium coolant, for example, can burn when exposed to air or water, and the Natrium’s design could experience uncontrollable power increases that result in rapid core melting.

Unlike light-water reactors, these non-light-water designs rely on materials other than water for cooling. Some developers contend that these reactors, still in the concept stage, will solve the problems that have plagued light-water reactors and be ready for prime time by the end of this decade.

The siren song of a cheap, safe and secure nuclear reactor on the horizon has attracted the attention of Biden administration officials and some key members of Congress, who are looking for any and all ways to curb carbon emissions. But will so-called advanced reactors provide a powerful tool to combat climate change? A Union of Concerned Scientists (UCS) analysis of non-light-water reactor concepts in development suggests that outcome may be as likely as Energy Commission Chairman Lewis Strauss’ famous 1954 prediction that electricity generated by nuclear energy would ultimately become “too cheap to meter.” Written by UCS physicist Edwin Lyman, the 140-page report found that these designs are no better—and in some respects significantly worse—than the light-water reactors in operation today.

The Koenigsegg Gemera is a four-seat hypercar that can do 0–62 mph in a claimed 1.9 seconds, but perhaps the most remarkable thing about this Swedish rocket ship is its 2.0-liter twin-turbocharged inline-3, which makes a staggering 600 horsepower (plus 443 pound-feet of torque).

Jason Fenske at Engineering Explained has the details on how Koenigsegg extracted so much power from such a small engine. It starts with the cylinders. There may not be many of them, but they are pretty big. They’re actually larger than the cylinders in Koenigsegg’s 5.0-liter V8, Fenske noted.

Koenigsegg’s new Gemera makes over 1700 horsepower, with close to a third of that figure coming from a 3-cylinder engine.

Late last year, a French company called Carmat received approval in Europe for its total artificial heart. It’s exactly what it sounds like: a heart made of synthetic and biological materials intended for implantation into people who need heart transplants. Now, just half a year later, the first US patient has received one of the hearts.

The transplant took place last week in a 39-year-old man at Duke University Hospital in North Carolina. The man didn’t go to the hospital expecting to have a heart transplant, but it ended up saving his life.
