The pace of those improvements has slowed, but International Business Machines Corp on Thursday said that silicon has at least one more generational advance in store.

IBM introduced what it says is the world’s first 2-nanometer chipmaking technology. The technology could be as much as 45% faster than the mainstream 7-nanometer chips in many of today’s laptops and phones and up to 75% more power efficient, the company said.

What Are ‘COVID Nails’—And Are They a Sign You’ve Had the Virus? Here’s What Doctors Say.

Tim Spector, a British epidemiologist and principal investigator of the Zoe COVID Symptom Study app, recently tweeted about the phenomenon and included a photo of COVID nails, writing, “Do your nails look odd? COVID nails are increasingly being recognized as the nails recover after infection and the growth recovers leaving a clear line. Can occur without skin rashes and appears harmless.”

Some people in the comments said they’ve definitely experienced this after having the coronavirus. “I noticed this and also hair loss 3 months after covid,” one wrote. “These were my post Covid nails! This was approx 2 months after the infection,” another said.

Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise controls of qubits that will aid the development of quantum industry-specific hardware to further new quantum simulation experiments and potentially quantum error correction processes for trapped ion qubits.

“Our algorithm calculates the hologram’s profile and removes any aberrations from the light, which lets us develop a highly precise technique for programming ions,” says lead author Chung-You Shih, a Ph.D. student at the University of Waterloo’s Institute for Quantum Computing (IQC).

Now, in a world’s first, Daniel Robinson, a veteran F-22 pilot, climbed inside a real aircraft and battled an AI virtual fighter.

These virtual war games open up new doors for training in the U.S. military. Often, the only way to train airmen is with real pilots who oppose them in air-to-air combat training. The U.S. military is increasingly relying on contractors to provide “red air” adversary support. But physically flying against adversary aircraft pilots is costly and inefficient. Earlier this year, the Air Force hired several companies — in a multi-billion dollar contract — to get the support they needed to help pilots train across the U.S.

Neodymium is critical to making the wheels of a Tesla spin or creating sound in Apple’s Airpods, and China dominates the mining and processing of this rare-earth mineral. So the U.S. and its allies are building their own supply chain. Photo illustration: Clément Bürge/WSJ

NASA’s Parker Solar Probe just took its closest pass to the Sun yet, veering so close that it “touched” the star’s blisteringly hot outer atmosphere — and gave NASA an unprecedented firsthand look at it.

The car-sized spacecraft has zoomed past the Sun a few times now, veering closer and closer each time, according to CNET. Each time, it uses nearby Venus’ gravitational pull as a sort of slingshot that helps it travel closer to the Sun and propels it at higher and higher speeds each time.

The slingshot is working so well that the space probe broke two records during its most recent solar approach last week.

The intractable “three-body problem” gets closer to being solved with breakthrough study.

The thumbnail-size amphibian lives in Brazil’s Atlantic Forest, which has lost 93 percent of its forest cover.
