(Arizona State University) In a new study, led by Petra Fromme and Nadia Zatsepin at the Biodesign Center for Applied Structural Discovery, the School of Molecular Sciences and the Department of Physics at ASU, researchers investigated the structure of Photosystem I (PSI) with ultrashort X-ray pulses at the European X-ray Free Electron Laser (EuXFEL), located in Hamburg, Germany.
(Leibniz Institute for Tropospheric Research (TROPOS)) Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but could now be observed for the first time in nature. This result was published by a team from TROPOS in npj Climate and Atmospheric Science, an Open Access journal published by Nature Research. Using laser and radar equipment, the team measured the vertical air velocity and ice formation in thin mixed-phase clouds.
(American Museum of Natural History) In terms of their body plan, Old World monkeys — a group that includes primates like baboons and macaques — are generally considered more similar to ancestral species than apes are. But a new study suggests that as far as locomotion goes, apes and Old World monkeys each evolved a way of moving that was different from the ancestral species as they adapted to different niches in their environments.
(University of Vienna) Scholars have been all over Rome for hundreds of years, but it still holds some secrets – for instance, relatively little is known about where the city’s denizens actually came from. Now, an international team led by Researchers from the University of Vienna, Stanford University and Sapienza University of Rome, is filling in the gaps with a genetic history that shows just how much the Eternal City’s populace mirrored its sometimes tumultuous history.
(Universitat Pompeu Fabra – Barcelona) Researchers led by David Comas for the first time performed an analysis of the complete genome of the population of North Africa. They have identified a small genetic imprint of the inhabitants of the region in Palaeolithic times, thus ruling out the theory that recent migrations from other regions completely erased the genetic traces of ancient North Africans.
