Turning spin loss into energy: New principle could enable ultra-low power devices

A research team has developed a device principle that can utilize “spin loss,” which was previously thought of as a simple loss, as a new power source for magnetic control.

The work is published in the journal Nature Communications.

Spintronics is a technology that utilizes the “spin” property of electrons to store and control information, and it is being recognized as a key foundation for next-generation information processing technologies such as ultra-low-power memory, neuromorphic chips, and computational devices for stochastic computation, as it consumes less power and is more nonvolatile than conventional semiconductors.

The Star That Almost Vanished: Astronomers Solve a Cosmic Mystery

Stars often reach the end of their lives and fade from view, but astronomers were left baffled when a star that had remained steady for more than ten years suddenly seemed to vanish for nearly eight months.

From late 2024 through early 2025, a star in our galaxy known as ASASSN-24fw lost about 97% of its brightness before returning to normal. The unusual dimming quickly became the subject of debate as researchers searched for an explanation behind such an extraordinary event.

An international research team, led by scientists at The Ohio State University, now believes they may have solved the puzzle. In a study recently published in The Open Journal of Astrophysics, the group reports that because the star’s color did not change during the dimming, the cause was unlikely to be related to stellar evolution. Instead, they conclude that a massive cloud of dust and gas surrounding the star blocked it from Earth’s view.

Your Eye Movements Could Be Hiding Signs of a Failing Memory

The ways our eyes explore the world change subtly over time, affected by age and illness.

A new study now suggests some of those changes could be used to identify problems with memory and cognition.

Researchers from Canada and the West Indies built on previous work by searching for variations in eye viewing patterns in people with and without a diagnosis for a brain health issue.
