The European Space Agency (ESA) has officially adopted ARRAKIHS as a scientific mission, confirming the target launch date of 2030. Matthieu Schaller is part of the science team: "I look forward to learning more about the dark part of our cosmos."
A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. Despite harboring remarkable diversity, populations in this vast region in the South Pacific historically have been overlooked in global human genetic studies, which have often focused largely on people of European descent, researchers say. The study is published in the journal Science.
A drop of dye added to a glass of water undergoes ordinary diffusion. However, when placed on the surface of a foam, the dye spreads differently—diffusion becomes anomalous. An example of this is the pattern on the froth of a cup of cappuccino. Interestingly, recent research suggests that diffusion equations in a heterogeneous environment can also describe social phenomena, such as election results or the behavior of stock market traders. The study is published in the Chaos: An Interdisciplinary
Researchers at the University of Greifswald have discovered a new mechanism by which bacteria such as Bacillus subtilis can regulate the production of the central metabolic molecule acetyl coenzyme A (Acetyl-CoA). Acetyl-CoA, also known as activated acetic acid, is crucial in the production of nutrients, i.e., proteins, carbohydrates and lipids, and thus plays a key role in the metabolism of all cells.
