📣Huge preprint 🔔
Today we share something our group has been working toward for a long time, led by @lucasmoriniere.bsky.social We asked can we predict which receptor a phage targets from its genome sequence alone? For most phages, we couldn’t. So Lucas set out to do something I had only dreamed of.

The harms of promoting the lab leak hypothesis for SARS-CoV-2 origins without evidence | Journal of Virology On Monday, June 3, 2024, Dr. Anthony Fauci, former Director of the National Institutes of Allergy and Infectious Diseases and a dedicated public health professional for over 40 years, testified voluntarily before the House subcommittee investigating the COVID-19 pandemic. Among other topics, he was asked about the origin of SARS-CoV-2, the coronavirus that causes COVID-19. The hearing was often disrupted and marked by contentious, disrespectful, and unfounded calls for Dr. Fauci to be “prosecuted” and imprisoned for “crimes against humanity.”

Very interesting commentary:
"There is currently no verified scientific evidence to support the lab leak hypothesis (of the SARS-CoV2)" journals.asm.org/doi/10.1128/...

Ce bilan revoit à la baisse les chiffres précédemment annoncés par le gouvernement.
