Scientists dramatically enhance the achievable resolution at free-electron lasers with a new technique
20-Jan-2021
Hard X-ray free-electron lasers (XFELs) have delivered intense, ultrashort X-ray pulses for over a decade. One of the most promising applications of XFELs is in biology, where researchers can capture images down to the atomic scale even before the radiation damage destroys the sample. In physics ...
3D images with record-breaking resolution
06-Jan-2021
An international team of scientists, led by Kartik Ayyer from the MPSD, has obtained some of the sharpest possible 3D images of gold nanoparticles. The resuts lay the foundation for obtaining high resolution images of macromolecules. The study was carried out at the European XFEL’s Single ...
New insights into how and how quickly the energy stored in a bent water molecule is dissipated into heat
11-Dec-2020
The water on Earth makes our planet inhabitable. It absorbs the Sun’s energy and releases it in the form of heat. An international research collaboration headed by the Max Planck Institute for Polymer Research (MPI-P) has now shown how and how fast the stored energy in the water molecules is ...
Breakthrough in material science: analysing frozen water atom by atom
09-Dec-2020
How to analyse ice down to its atomic scale? And how to analyse objects embedded in ice without melting it? An international team of material scientists mainly from the Max-Planck-Institut für Eisenforschung (MPIE) found a way to analyse micron-thick layers of ice by atom probe tomography (APT) ...
New milestone in frequency comb spectroscopy
30-Nov-2020
Scientists at the Max Planck Institute of Quantum Optics (MPQ) have succeeded in testing quantum electrodynamics with unprecedented accuracy to 13 decimal places. The new measurement is almost twice as accurate as all previous hydrogen measurements combined and moves science one step closer to ...
A user-friendly method to reconstruct and analyze SSU rRNA from raw metagenome data
10-Nov-2020
First the background: Microbiologists traditionally determine which organisms they are dealing with using the small subunit ribosomal RNA or in short SSU rRNA gene. This marker gene allows to identify almost any living creature, be it a bacterium or an animal, and thus assign it to its place in ...
Max Planck Innovation licenses process for the generation of organ-like tissue aggregates to biotech company StemoniX
05-Nov-2020
Sometimes hundreds of thousands of potential therapeutics need to be tested in large-scale, fully automated experiments to identify a single effective drug. Most compounds do not work as desired, and some are even toxic. Since the development of the induced Pluripotent Stem (iPS) Cell technology ...
Novel technique visualizes individual atoms in a protein with cryo-electron microscopy for the first time
23-Oct-2020
A crucial resolution barrier in cryo-electron microscopy has been broken. Holger Stark and his team at the Max Planck Institute (MPI) for Biophysical Chemistry have observed single atoms in a protein structure for the first time and taken the sharpest images ever with this method. Such ...
This enables scientists to track down causes of diseases more quickly
22-Oct-2020
The way DNA is organized in the cell nucleus is very important for the normal development and function of the cell. A mutation that affects the packaging of the genetic material in the cell nucleus can lead to developmental disorders or diseases such as cancer. A team of scientists from the Max ...
Neandertals have adopted male sex chromosome from modern humans
28-Sep-2020
An international research team led by Martin Petr and Janet Kelso of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has determined Y chromosome sequences of three Neandertals and two Denisovans. These Y chromosomes provide new insights into the relationships and ...
