Around the Web

Batting Average
Supaporn Wacharapluesadee was the first scientist outside of China to sequence SARS-CoV-2. Jon Cohen writes for Science about her efforts to prevent the next pandemic by finding novel bat viruses before they spill over to humans. There is growing support for focusing more science on animal viruses as a way to anticipate and prevent spillover to humans. In 2020 Rodrigo Pérez Ortega wrote for Quanta on recent research into self-disseminating vaccines for wildlife.


Feeling Ghosted
Neutrinos are perhaps the most puzzling particles in the Standard Model. Uncovering their mysteries could help us reveal the secrets of dark matter, too, as Jackson Ryan explains for CNET. Physicists think that several conflicting neutrino measurements could be resolved by introducing a new "dark sector" of particles. These particles might simultaneously explain dark matter and dark energy, Thomas Lewton wrote for Quanta in 2021.
