Computer simulations show how low-intensity illumination can be used to terminate cardiac arrhythmias.

A combination of X-ray crystallography, NMR, and mass spectrometry has revealed how diverse small-molecule inhibitors bind Bruton’s tyrosine kinase and alter the conformation of this enzyme.

Osteocalcin is a bone matrix protein that acts like a hormone when it reaches the blood, and has different effects in mice and humans.

Atomic structures of mitochondrial enzyme complexes in plants are shedding light on their multiple functions.

A simulation study demonstrates a better method for separating genetic effects from environmental effects in genome-wide association studies, but there is still some way to go before this becomes a "solved" problem.

During sleep, the brain experiences large fluctuations in blood volume and altered coupling between neural and vascular signals.

HOAP is a telomere-binding protein that has a conserved role in Drosophila, but it also needs to evolve quickly to restrict telomeric retrotransposons.

The skeletal muscle of fruit flies communicates with other organs to prevent the accumulation of too much fat and to protect adults against obesity.

Experiments with hybrid viruses are illuminating how SARS-CoV-2 can escape neutralizing antibodies.

Analysis of the smallest known arthropod genome reveals a mechanism for genome reduction that appears to be driven by a specialized ecological interaction with plants.
