Mystery molecule in bacteria is revealed to be a guard
Unusual structures in bacterial cells keep viral infection from spreading
09-Nov-2020
Peculiar hybrid structures called retrons that are half RNA, half single-strand DNA are found in many species of bacteria. Since their discovery around 35 years ago, researchers have learned how to use retrons for producing single strands of DNA in the lab, but no one knew what their function was ...
Malaria pathogens under the X-ray microscope
X-ray microscopy at BESSY II reveals how antimalaria-drugs might work
04-Nov-2019
Malaria is one of the most threatening infectious diseases in the world. An international team has now been able to investigate malaria pathogens in red blood cells in vivo using the BESSY II X-ray microscope and the ALBA and ESRF synchrotron sources. The scientists reveal the mechanisms used by ...
Tough aqua material for water purification
20-Jan-2017
Water purification processes usually make use of robust membranes for filtering off contaminants while working at high pressures. Can materials employing water as major component be made strong enough to suit such a demanding application? Israeli scientists now report that a supramolecular aqua ...
DNA dominos on a chip
Carriers of genetic information packed together on a biochip like in nature
11-Aug-2016
Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. An international team of physicists has now succeeded in artificially ...
Stability of cheap solar cells improved
04-Aug-2016
The stability of a very efficient and cheap material for solar cells has now been enhanced by up to two orders of magnitude. The material manipulations that enabled this enhancement were developed in a project supported by the Austrian Science Fund FWF. Lead-halide perovskites are the darling of ...
Eating air, making fuel
27-Jun-2016
All life on the planet relies, in one way or another, on a process called carbon fixation: the ability of plants, algae and certain bacteria to "pump" carbon dioxide (CO2) from the environment, add solar or other energy and turn it into the sugars that are the required starting point needed for ...
