The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet.

Scientists have found a new way to control the alignment state of magnetic atoms in an antiferromagnetic material, showing promise for the development of tiny sensors and memory devices. Researchers now describe their new approach featuring a controllable exchange bias effect, which enables the asymmetric magnetic actions of devices comprised of complex combination structure of different types of magnetic materials.

A recent project has revealed innovative methods that could dramatically improve the performance of future electrical vehicles (e-vehicles).

A research team has developed new technology that uses tiny smart devices known as spin-torque oscillators to harvest and convert wireless radio frequencies into energy to power small electronics.

Classic computers use binary values (0/1) to perform. By contrast, our brain cells can use more values to operate, making them more energy-efficient than computers. This is why scientists are interested in neuromorphic (brain-like) computing. Physicists have used a complex oxide to create elements comparable to the neurons and synapses in the brain using spins, a magnetic property of electrons.

Astrophysicists has developed the most realistic, highest-resolution 3D simulation of star formation to date. Called STARFORGE (Star Formation in Gaseous Environments), the computational framework is the first to simulate an entire gas cloud -- 100 times more massive than previously possible and full of vibrant colors -- where stars are born.

A branch of artificial intelligence (AI), called machine learning, can accurately predict the risk of an out of hospital cardiac arrest -- when the heart suddenly stops beating -- using a combination of timing and weather data.

Microdiamonds with nitrogen vacancy centers are increasingly used as biological tracers thanks to the optical fluorescence of NV centers. But the NV centers also can be spin-polarized by low-power lasers, and the polarized centers then polarize nearby carbon-13 atoms occurring naturally in the diamonds. These hyperpolarized C-13 atoms can be detected by NMR imaging. Chemists now demonstrate dual-mode imaging with NV-center diamonds, potentially allowing high-quality imaging 10 times deeper than with optics alone.

Scientists have developed an algorithm to train computers to analyze signals from subatomic particles embedded in advanced electronic materials.

A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
