The NIH’s Most Reckless Cuts Yet Ending clinical trials with no warning can put patients at risk.

How to communicate the value of curiosity-driven research The burden of proof is on us, as researchers, to explain why what we do is valuable to society.

'Skeptics often push back and question why, if basic science is so valuable, we can’t just count on companies—startups and big pharma—to fund it. The answer here is that only government and nonprofit funding can truly support the long arc of scientific discovery.'

It is worth paying close attention to the new bill "Dangerous Viral Gain of Function Research Moratorium Act" introduced by Senator Roger Marshall.

If enacted, it will effectively stop all of virological research, including for vaccines.

So - I've actually led Ebola outbreak response at USAID.

This is bunk from Elon. They have laid off most of the experts, they're bankrupting most of the partner orgs, have withdrawn from WHO, and muzzled CDC.

The type 2 immune response in gut homeostasis and parasite transmission in malaria Malaria predisposes to concomitant bacteremia, resulting in increased mortality risk. Previous studies indicated that malaria causes structural changes in the intestine, induces tolerogenic immune responses, inhibits neutrophil recruitment, suppresses innate synthesis of IFN-γ, dysregulates mast cells (MCs) and basophils, and induces Th2-type immune responses. These can reduce parasite control while increasing enteropathogenic dissemination. Moreover, there is growing evidence that Th2 immunity, while protecting the host from overwhelming inflammation, may also contribute to increased parasite transmission. This review explores the roles of the regulatory immune response in bacterial coinfections and parasite transmission in malaria.

Our brand new review on type 2 immunity in malaria with terrific colleagues Renee Tsolis and Adrian Piliponsky highlighting the roles of mast cells and basophils in orchestrating the host response to infection and parasite transmission to Anopheles mosquitoes.

This year, the term “scientist” turns 190 years old!
It was coined by William Whewell, who also considered the alternatives:
“savant”,
“philosopher”,
“nature-poker”, and
“nature-peeper”
Did he choose the right one?
