Missing atoms appear after a neutron star collision

Two neutron stars shattered the universe, triggering an epic explosion called "Kilonova," which spewed loads of ultra-dense, ultra-fast material into space. Now, astronomers have presented the most conclusive evidence that an element with missing links has formed after this explosion that could provide an explanation for the confusing chemistry of the universe. When this tremor – curled up exactly in …

Researchers are building a heat shield with a thickness of only 10 atoms to protect electronic devices

This greatly magnified image shows four layers of atomically thin materials that form a heat shield that is only two to three nanometers thick, or about 50,000 times thinner than a sheet of paper. Credit: National Institute for Standards and Technology Excess heat emitted by smartphones, laptops, and other electronic devices can be annoying, but can also cause malfunction and, …

Quantum sensor breakthrough due to naturally occurring vibrations in artificial atoms

Credit: CC0 Public Domain A team of scientists headed by the University of Bristol has discovered a new method for building ultrahigh-precision quantum sensors. When single atoms emit light, they do so in discrete packets called photons. When this light is measured, this discrete or "grainy" nature leads to particularly small fluctuations in brightness, since two or more photons are …
