Computer simulations suggest early comets usually struck Earth too fast for hydrogen cyanide to survive, weakening a theory dating to at least 1961 while leaving asteroids, primordial chemistry and ancient Mars open for further study.
Researchers adjusted for brain donation bias and estimated that about 3 in 4 former NFL players who died from 2008 through 2023 had CTE, while experts cautioned that the disease does not always cause symptoms.
The FDA is proposing new requirements for four essential infant formula nutrients, beginning a broader review that will eventually examine all required nutrients, possible additions and carbohydrate sources, though consumers may not see changes for several years.
