Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

“We have 1,544 measles cases this year, 92% in unvaccinated people, and 3 deaths. The problem isn’t the vaccine — it’s that people aren’t getting it. O’Neill hasn’t offered a single scientific rationale for breaking up MMR.”

Anthropologists Have A Bone To Pick With New Skull Finding
A reconstruction of an ancient skull suggests that humans could have evolved half a million years earlier than thought. Not so fast, some say.

Influenza A virus RNA found in airborne particles from pigs across a range of particle sizes. For reference a 10 micron particle takes ~8 minutes to settle to the ground from a height of 5 feet. That's plenty of time for it to drift around and be inhaled by others.
