A dedicated team of scientists is spending the next four weeks in northern Chile’s Atacama Desert. They are studying the scarce life that exists there and, in the process, helping NASA learn more about how primitive life forms could exist on Mars.
The NASA-funded researchers are studying the Atacama Desert, described as the most arid region on Earth, to understand the desert as a habitat that represents one of the limits of life on Earth. The project, part of NASA’s Astrobiology Science and Technology Program for Exploring Planets, involves technology experiments to test robotic capabilities for mobility, autonomy and science.
"Identifying living microorganisms and/or fossils in environments where life’s density is among the lowest on the planet should provide leads to establish detection criteria and strategies for Mars or other planetary bodies," explained Dr. Nathalie Cabrol of the SETI Institute, Mountain View, Calif., and NASA Ames Research Center, located in California’s Silicon Valley. She is the project science lead and co-investigator on the "Life in the Atacama" project.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
