The researchers observed how an enzyme from drug-resistant tuberculosis bacteria damages an antibiotic molecule. The new technique provides a powerful tool to examine changes in biological molecules as they happen.
Water is more complicated than it seems. Now a study led by researchers at Stockholm University has probed the movements of its molecules on a timescale of millionths of a billionth of a second.
Experiments at SLAC heated water from room temperature to 100,000 degrees Celsius in less than a millionth of a millionth of a second, producing an exotic state of water that could shed light on Earth’s most important liquid.
By placing the tiniest strands of proteins on one-atom-thick graphene, scientists capture promising X-ray laser images of these elusive biomolecules that play a key role in neurodegenerative diseases.
Like turning a snowball back into fluffy snow, a new technique turns high-density materials into a lower-density one by applying the chemical equivalent of ‘negative pressure.’
The liquid sheets – less than 100 water molecules thick – will let researchers probe chemical, physical and biological processes, and even the nature of water itself, in a way they could never do before.
The foils, each made from a single chemical element, are used to calibrate X-ray equipment at SLAC’s SSRL synchrotron, and were donated by long-time user, Farrel Lytle.
SLAC and its collaborators are transforming the way new materials are discovered. In a new report, they combine artificial intelligence and accelerated experiments to discover potential alternatives to steel in a fraction of the time.
The new technology could allow next-generation instruments to explore the atomic world in ever more detail.
When it comes to making molecular movies, producing the world’s fastest X-ray pulses is only half the battle. A new technique reveals details about the timing and energy of pulses that are less than a millionth of a billionth of a second long, which can be used to probe nature’s processes at this amazingly fast attosecond timescale.
