For the first time, scientists have revealed the steps needed to turn on a receptor that helps regulate neuron firing. The findings might help researchers understand and someday treat addiction, psychosis and other neuropsychological diseases.

Researchers expect the new method to answer fundamental questions in biology and materials science. First up: Images showing molecules that help guide cell division in bacteria.

Physicists at SLAC and Stanford propose that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules.

Understanding nature’s process could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.

The lab is responding to the coronavirus crisis by imaging disease-related biomolecules, developing standards for reliable coronavirus testing and enabling other essential research.

Researchers investigate how much damage spreads through molecules struck by a pulse from LCLS.

This new technology could enable future insights into chemical and biological processes that occur in solution, such as vision, catalysis and photosynthesis.

The giant cavity, in a protein that transports nutrients across the cell membrane, is unlike anything researchers have seen before.

An LCLS imaging technique reveals how a mosquito-borne bacterium deploys a toxin to kill mosquito larvae. Scientists hope to harness it to fight disease.

The 1950s and ‘60s poisoning event was long attributed to methylmercury, but studies at SLAC suggest a different compound was to blame. The findings could reshape toxicologists’ understanding of disease related to mercury poisoning.

A better understanding of this phenomenon, which is crucial to many processes that occur in biological systems and materials, could enable researchers to develop light-sensitive proteins for areas such as biological imaging and optogenetics.

Cryogenic electron microscopy can in principle make out individual atoms in a molecule, but distinguishing the crisp from the blurry parts of an image can be a challenge. A new mathematical method may help.
