Scientists "domesticate" -- and disarm -- malaria parasite
Malaria is one of the Earth’s most notorious scourges, accounting for more than 250 million new cases — and one million deaths — each year, researchers have developed a novel technique to “tame” the malaria parasite by forcing it to depend on an external supply of a vital chemical; this could help to speed up drug development and provide the basis for the first effective vaccine against malaria

Vaccine Integrity Project Says New FDA Rules on COVID-19 Vaccines Show Lack of Consensus, Clarity
Sidestepping both the FDA’s own Vaccines and Related Biological Products Advisory Committee and the CDC’s Advisory Committee on Immunization Practices (ACIP), two Trump-appointed FDA leaders penned an opinion piece in the New England Journal of Medicine to announce new, more restrictive, COVID-19 vaccine recommendations. Critics say that not seeking broad input into the new policy, which would help FDA to understand its implications, feasibility, and the potential for unintended consequences, amounts to policy by proclamation.
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
