Looking for hidden states of the COVID-19 spike protein

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells ...

Phasing out a microscope's tricks

An instrument error can lead to complete misidentification of certain crystals, reports a KAUST study that suggests researchers need to exercise caution when using electron microscopes to probe two-dimensional (2-D) semiconductors.

Exploring oxidative pathways in nuclear fuel

Powerful atomic-resolution instruments and techniques at Pacific Northwest National Laboratory (PNNL) are revealing new information about the interaction of uranium dioxide (UO2) with water. These new insights will improve ...

Scientists find new way to measure important beam property

For a wide variety of high-powered scientific instruments, from free-electron lasers to wakefield accelerators to electron microscopes, generating a bright electron beam that has specific properties represents one of the ...

Artificial materials for more efficient electronics

The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing "made-to-order" materials and more energy-efficient electronics.
