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.
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.
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.
