DESY X-ray lightsource identifies promising candidates for COVID drugs

Existing active substances bind to key virus protein

07-Apr-2021

A team of researchers has identified several candidates for drugs against the coronavirus SARS-CoV-2 at DESY´s high-brilliance X-ray lightsource PETRA III. They bind to an important protein of the virus and could thus be the basis for a drug against Covid-19. In a so-called X-ray screening, the ...

Bacteria needle under the electron microscope

Researchers watch injectisome of gram-negative bacteria in action for the first time

15-Mar-2021

For the first time, researchers have revealed the syringe-like type-III secretion system of Gram-negative bacteria in action. In the research study, published in Nature Communications, the group of Thomas Marlovits from the Centre for Structural Systems Biology (CSSB) at the DESY campus provides ...

Researchers watch nanomaterials growing in real time

New world record in the temporal resolution achieved using GISAXS, a surface-sensitive scattering technique

17-Feb-2021

For the first time, a team of scientists has succeeded in capturing in real time the first few milliseconds in the life of a gold coating as it forms on a polymer. The team used DESY’s high-brilliance X-ray source PETRA III to observe the earliest stages in the growth of a metal-polymer hybrid ...

Exploding water jet in X-ray beam

X-ray laser sheds light on ultrafast processes in physics, biology and material sciences

05-Jan-2021

An interdisciplinary team of scientists has used ultrashort X-ray pulses to image extremely rapidly exploding jets of water. The experiments, carried out at the European X-ray laser facility European XFEL, aim to study ultrafast events that occur in a very small region by means of X-ray ...

Liquid water at 170 degrees Celsius

X-ray laser reveals anomalous dynamics at ultra-fast heating

18-Sep-2020

Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic ...

Two colour technique reveals how X-ray lasers damage biomolecules

Step to a fuller understanding of how X-ray flashes modify the structure of proteins

03-Jun-2020

X-ray lasers can reveal the spatial structures of biomolecules that are hard to come by with other methods. However, the intense X-ray flashes vaporise the samples almost immediately. An international team of scientists has now followed how this radiation damage spreads in biomolecules to ...
