Hayashi et al. demonstrate that human touch-induced pleasurable tickling promotes affinity between rats and human hands. This is accompanied by increased OTR expression in the VMHvl, and blocking the oxytocin signaling inhibits such affinity. Find out more here: www.cell.com/current-biol...

A paper from our pancoronavirus vaccine P01 grant group is now out in Science Translational Medicine. Here we show that non-stabilized spike delivered as mRNA is sufficient to elicit broadly neutralizing antibodies in monkeys. @alexschaefer.bsky.social www.science.org/doi/10.1126/...

Nonstabilized SARS-CoV-2 spike mRNA vaccination induces broadly neutralizing antibodies in nonhuman primates
Nonstabilized SARS-CoV-2 spike mRNA vaccination elicited distinct antibodies to either Omicron variants of concern or preemergent sarbecoviruses.

Researchers challenged longhorn crazy ants and humans with the same task: maneuvering a T-shaped object through two consecutive open doorways. Single humans always outperformed single ants, but ant groups could beat human groups. In PNAS: www.pnas.org/doi/10.1073/...

Ebola disease: bridging scientific discoveries and clinical application
The west Africa Ebola disease epidemic (2014–16) marked a historic change of course for patient care during emerging infectious disease outbreaks. The epidemic response was a failure in many ways—a slow, cumbersome, and disjointed effort by a global architecture that was not fit for purpose for a rapidly spreading outbreak. In the most affected countries, health-care workers and other responders felt helpless—dealing with an overwhelming number of patients but with few, if any, tools at their disposal to provide high-quality care.
