Reported recently in a new study published in Nature, a team of researchers, led by JILA and NIST Fellow and University of Colorado Boulder Physics professor Jun Ye, in collaboration with Professor Eric Hudson’s team at UCLA’s Department of Physics and Astronomy, have found a way to make nuclear clocks a thousand times less radioactive and more cost-effective, thanks to a method creating thin films of thorium tetrafluoride (ThF4).
Researchers at Stanford’s Knight Initiative for Brain Resilience merge spatial transcriptomics and AI to uncover how local cellular interactions drive brain aging and resilience.
MIT researchers can now fabricate a 3D chip with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon substrates between the layers, leading to better and faster computation, for applications like more efficient AI hardware.
MIT physicists have created a new and long-lasting magnetic state in a material, using only light. The results provide a new way to control and switch antiferromagnetic materials, which are of interest for their potential to advance information processing and memory chip technology.
