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 ...
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 ...
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 ...
Combination of techniques locates microcrystals for structural analysis
26-Nov-2020
A novel kind of microscope is able to detect tiny protein crystals, which are beyond the imaging power of even modern light microscopes. The innovative technique relies on various non-linear optical effects to image even nanocrystals, which are increasingly being used for protein structure ...
X-ray analysis reveals structure of molecular machinery of malaria and toxoplasmosis pathogens
03-Nov-2020
An investigation at DESY's X-ray source PETRA III provides new insights into the molecular machinery by which certain parasites travel through the human organism. The study, led by Christian Löw from the Hamburg branch of the European Molecular Biology Laboratory EMBL, analyzed the so-called ...
Study shows possible new way to create DNA base pairs
06-Oct-2020
In the search for the chemical origins of life, researchers have found a possible alternative path for the emergence of the characteristic DNA pattern: According to the experiments, the characteristic DNA base pairs can form by dry heating, without water or other solvents. The team led by Ivan ...
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 ...
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 ...
Gallium nitride is the second most important semiconductor material after silicon
28-Feb-2020
Using a special pressure furnace, an international team of researchers has analysed the initial stages of the growth of the semiconductor gallium nitride with X-ray light. The observations show for the first time the atomic structure of the interface of the semiconductor material with liquid ...
X-ray laser reveals structure of a key enzyme of the parasite Trypanosoma brucei
04-Feb-2020
Using ultra-bright X-ray flashes, a team of researchers has tracked down a potential target for new drugs against sleeping sickness: The scientists have decoded the detailed spatial structure of a vital enzyme of the pathogen, the parasite Trypanosoma brucei. The result provides a possible ...
