In 2021, a team led by MIT physicists reported creating a new ultrathin ferroelectric material, or one where positive and negative charges separate into different layers. At the time, they noted the material’s potential for applications in computer memory and much more...

Ever see a Star Explode? You’re about to get a chance very soon

Every clear night for the last three weeks, Bob Stephens has pointed his home telescope at the same two stars in hopes of witnessing one of the most violent events in the universe—a nova explosion a hundred thousand times brighter than the sun.

The eruption, which scientists say could happen any day now, has excited the interest of major observatories worldwide, and it promises to advance our understanding of turbulent binary star systems.

Yet for all the high-tech observational power that NASA and other scientific institutions can muster, astrophysicists are relying on countless amateur astronomers like Stephens to spot the explosion first.

The reason? It’s just too costly to keep their equipment focused on the same subject for months at a ...

New study shows ‘Dancing Molecules’ can Regenerate Cartilage in 3 days

In November 2021, Northwestern University researchers introduced an injectable new therapy, which harnessed fast-moving “dancing molecules,” to repair tissues and reverse paralysis after severe spinal cord injuries.

Now, the same research group has applied the therapeutic strategy to damaged human cartilage cells. In the new study, the treatment activated the gene expression necessary to regenerate cartilage within just four hours. And, after only three days, the human cells produced protein components needed for cartilage regeneration.

The re...

Engineers develop Magnetic Tunnel Junction–based Device to make AI more Energy Efficient

Researchers develop state-of-the-art device to make artificial intelligence more energy efficient

Engineering researchers at the University of Minnesota Twin Cities have demonstrated a state-of-the-art hardware device that could reduce energy consumption for artificial intelligent (AI) computing applications by a factor of at least 1,000.

The research is published in npj Unconventional Computing titled “Experimental demonstration of magnetic tunnel junction-based computational random-access memory.” The researchers have multiple patents on the technology used in the device.

With the growing demand for AI applications, researchers have been looking at ways to create a more energy efficient process, while keeping performance high and costs low...
