New device entangles free electrons with photons

Physics World: The quantum entanglement of a free electron with a photon has been achieved by researchers in Germany and Switzerland. The team, led by Armin Feist at the Max Planck Institute for Multidisciplinary Sciences, achieved the feat using a new…

Simple method creates stretchy color-changing films

C&EN: Engineers at the Massachusetts Institute of Technology have demonstrated a fast, scalable, and cost-effective method to produce films that change color when stretched (Nat. Mater. 2022, DOI: 10.1038/s41563-022-01318-x). Using a digital projector and commercially available light-sensitive polymers, they were…

New approach can better monitor the placenta

Futurity: Researchers report a new way to monitor the placenta in pregnant patients. By combining optical measurements with ultrasound, the findings show how oxygen levels can be monitored non-invasively and provides a new way to generate a better understanding of…

Webb telescope reveals unpredicted bounty of bright galaxies in early universe

Science: The James Webb Space Telescope has only been watching the sky for a few weeks, and it has already delivered a startling finding: tens, hundreds, maybe even 1000…
