Why are planetary scientists, astrobiologists and and SETI scientists so negative (pissed off, even) about Avi Loeb’s repeated claims that 3I/Atlas may be an invading alien spaceship?

Murine norovirus and influenza virus H5N1 can survive the process of making cheese from raw milk, persisting for weeks. Thus, it is recommended that milk contaminated with viruses be heat-treated to ensure safety. Get more info in #AppEnvMicro: asm.social/2Gi

The US withdrawal from WHO could impact the flu shot.

Why next year's flu shot might not be as good as it should be
America's withdrawal from the World Health Organization is affecting the ability of U.S. scientists to track flu and other pathogens. That could be a blow to the development of the 2025 flu vaccine.

If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really!
It was the FRAME that was off--very off, from the first line.
And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

When the flood of heavy CO2 gas rolls over the landscape it suffocates everything in its path and shuts off car engines, which need oxygen.
