Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.

For decades, scientists have been studying a group of unusual materials called multiferroics that could be useful for a range of applications including computer memory, chemica...

New observations reveal neutron stars paired with stars like our Sun. Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.

Most stars in our universe come in pairs. While our own Sun is a loner, many stars like our Sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example, are often found orbiting each other...

Building upon groundbreaking research demonstrating how the SARS-CoV-2 virus disrupts mitochondrial function in multiple organs, researchers from Children’s Hospital of Philadelphia (CHOP) demonstrated that mitochondrially-targeted antioxidants could reduce the effects of the virus while avoiding viral gene mutation resistance, a strategy that may be useful for treating other viruses.

The preclinical findings were published in the journal Proceedings of the National Academy of Sciences.

Last year, a multi-institutional consortium of researchers found that the genes of the mitochondria, the energy producers of our cells, can be negatively impacted by the virus, leading to dysfunction in multiple organs beyond the lungs.

SARS-CoV-2 proteins can...

Scientists propose a new way of implementing a neural network with an optical system which could make machine learning more sustainable in the future. The researchers at the Max Planck Institute for the Science of Light have published their new method in Nature Physics, demonstrating a method much simpler than previous approaches.

Machine learning and artificial intelligence are becoming increasingly widespread with applications ranging from computer vision to text generation, as demonstrated by ChatGPT. However, these complex tasks require increasingly complex neural networks; some with many billion parameters...
