Scientists may have found the first “free-floating” black hole, as it moves around our Milky Way galaxy.

When large stars collapse, they are thought to leave behind black holes. If that is the case, there should be hundreds of millions scattered throughout the Milky Way, left behind after the death of those stars.

But scientists have struggled to find them. Isolated black holes are invisible.

Summary: An older person’s posture may give clues to hidden cognitive decline, a new study reports.

A mass survey of citizens aged 50 to 89 years examined whether cognitive decline could be detected by sagittal spinal balance measurement based on a radiological approach. Doctors from Shinshu University observed associations of sagittal vertical axis (SVA) anteriorization and higher age with lower cognitive function.

“If something drastic doesn’t change in the next few weeks/months, I promise you, you’ll see empty shelves everywhere you look,” Smith wrote in a post that was shared nearly 290,000 times. “You’ll see chaos as people fight for the basic necessities of everyday life.”

Smith did not respond to a request for comment from Insider in time for publication.

Insider spoke with five truckers who warned that the industry could be at a breaking point. The drivers say they’ve had to get creative in recent months as they work to turn a profit while spending thousands at the pump.

Cells not replaced, but old cells that are still there are rejuvenated.

Dr David Sinclair explains the mechanism behind how to reprogramm the old cells rejuvenate to be young again. He also clarify the process is based on cell autonomous effect and does not involve or rely on any stem cells in this clip.

As part of AMD’s Financial Analysts Day 2022, AMD has provided updates to its Server CPU roadmap going into 2024. The biggest announcement is that AMD is already planning for the (next) next-gen core for its successful EPYC family, the 5th generation EPYC series, which has been assigned the codenamed Turin. Some key announcements include various segmentations of its expected EPYC 7,004 portfolio, including Genoa, Bergamo, Genoa-X, and Siena.

NASA’s Mars helicopter has run into a bit of trouble after 28 successful flights and well over an entire dusty Earth year into its mission on the Red Planet.

One of the four-pound rotorcraft’s navigation sensors has given out — an unfortunate new development, especially considering Martian winter is almost upon it. Extreme temperature swings could soon wreak havoc on the rest of the helicopter’s electronics.

But the team at NASA’s Jet Propulsion Lab says their plucky rotorcraft isn’t finished yet.

When moving furniture, heavy objects are easier to move if you rotate them while pushing. Many people intuitively do this. An international research team from Konstanz (Germany), Trieste and Milan (Italy) has now investigated on the microscopic scale the reduction in static friction caused by simultaneous rotation.

In their recent study, to be published in Physical Review X on June 15, the researchers found that the reduction in static friction of a microscopic object on a crystalline surface can be described by moiré patterns, which occur when periodic patterns superimpose. Based on this concept, the researchers predict an unusual state, in which microscopic objects can be set in rotation by applying a minimal amount of torque. In the future, this could enable the construction of micro-machines with ultra-low static friction against rotation.

Differing values of the Hubble constant might be reconciled via the dark sector.

A team of researchers at the Graduate School of Informatics, Nagoya University, have brought us one step closer to the development of a neural network with metamemory through a computer-based evolution experiment. This type of neural network could help experts understand the evolution of metamemory, which could help develop artificial intelligence (AI) with a human-like mind.

The research was published in the scientific journal Scientific Reports.

What is Metamemory?
