B cells of the immune system discovered in the meninges

Researchers found large numbers of B cells and their immature progenitors in the outer layer of the meninges, a surprising discovery that suggests these cells play a special immune system function there. The study used single-cell RNA sequencing to analyze the genes active in each individual cell and confirmed the finding in human tissue.

Droplets with coronaviruses last longer than previously thought

Research by TU Wien found that small droplets with coronaviruses can remain airborne for an order of magnitude longer than assumed due to high humidity. This means that even short-range exposure poses a significant risk, highlighting the need for scientifically sound guidelines on mask-wearing and safety distances.

Studying thermophoresis in space

A multidisciplinary team of Lehigh University researchers will conduct experiments on thermophoresis in complex fluids for bioseparations at the International Space Station. The team hopes to understand how temperature gradients affect particles and improve virus separation techniques with potential societal impact.

Ancient DNA rewrites early Japanese history -- modern day populations have tripartite genetic origin

New study finds that modern Japanese populations have a tripartite genetic origin, with contributions from Jomon hunter-gatherers, Yayoi farmers, and Kofun peoples. The analysis reveals a complex history of population dynamics, including assimilation rather than replacement during the agricultural transition.
