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?

To begin the process of bioprinting an organ, doctors typically start with a patient’s own cells. They take a small needle biopsy of an organ or do a minimally invasive surgical procedure that removes a small piece of tissue, “less than half the size of a postage stamp,” Atala said. “By taking this small piece of tissue, we are able to tease cells apart (and) we grow and expand the cells outside the body.”

This growth happens inside a sterile incubator or bioreactor, a pressurized stainless steel vessel that helps the cells stay fed with nutrients – called “media” – the doctors feed them every 24 hours, since cells have their own metabolism, Lewis said. Each cell type has a different media, and the incubator or bioreactor acts as an oven-like device mimicking the internal temperature and oxygenation of the human body, Atala said.

“Then we mix it with this gel, which is like a glue,” Atala said. “Every organ in your body has the cells and the glue that holds it together. Basically, that’s also called ‘extracellular matrix.’”.
