A new method to build more energy-efficient memory devices could lead to a sustainable data future

A research team led by Kyushu University has developed a new fabrication method for energy-efficient magnetic random-access memory (MRAM) using a new material called thulium iron garnet (TmIG) that has been attracting global attention for its ability to enable high-speed, low-power information rewriting at room temperature. The team hopes their findings will lead to significant improvements in the speed and power efficiency of high-computing hardware, such as that used to power generative AI.

The work is published in npj Spintronics.

The rapid spread of generative AI has made the power demand from data centers a global issue, creating an urgent need to improve the energy efficiency of the hardware that runs the technology.

California physicist and Nobel laureate John Martinis won’t quit on quantum computers

A California physicist and Nobel laureate who laid the foundation for quantum computing isn’t done working.

For the last 40 years, John Martinis has worked—mostly within California—to create the fastest computers ever built.

“It’s kind of my professional dream to do this by the time I’m really too old to retire. I should retire now, but I’m not doing that,” the now 67-year-old said.

Ultra-Thin LED Brings Natural Sunlight Indoors

Scientists have created a light as thin as paper that emits a gentle, natural glow similar to sunlight.

By using a precise mix of quantum dots, the team reproduced the full color range of daylight. The design could lead to more comfortable, eye-friendly lighting and next-generation display screens.

Paper-Thin Breakthrough in LED Technology.

Scientists Discover the Secret to This Bizarre Creature’s Extraordinarily Long Life

A few tiny molecular tweaks may explain why naked mole-rats live nearly ten times longer than similar species. Researchers believe the key to the naked mole-rat’s remarkable lifespan may come down to small but significant differences in just four amino acids. A recent study found that evolutionar

Two Black Holes Locked in a Death Spiral Imaged in Stunning First

The complex dance of two black holes locked in a doomed orbit has been revealed in a first-of-its-kind direct radio image.

It’s the first time astronomers have directly imaged the distinct jets of both black holes in a known binary – finally confirming the model of the double core of a galaxy called OJ 287.

In OJ 287, located some 3.5 billion light-years away, the intricate, extreme interplay between the two central supermassive black holes has been documented for decades. This is the first image to capture smoking-gun signatures of both objects, however.
