The red wine headache has long been a mystery. Is it sulfites, tannins, alcohol itself?

Researchers have looked into it. And each one of them made some sense, but each one of them has in succession been ruled out and sort of disproven.

It's Friday, December 8th, and would you take a look at that? Today is Science Friday.

I'm Scifry producer Kathleen Davis.

Since ancient Greece, people have complained about headaches shortly after drinking

red wine.

It's not the same thing as a hangover, and lots of theories about what causes it have been

debunked. A new report suggests a new culprit,

Corsitan, an antioxidant found in grape skins. Flora Lichtman will talk about that in just a moment, but first a round up of the top science stories of the week.

Smoke from increased wildfires in the US has reversed progress made in cleaning America's air, caused

hundreds of deaths between 2000 and 2020 according to a new study published in

the Lancet. Joining me to talk about this another science stories of the week is

Rachel Feltman, host of the weirdest thing I learned this week. That is the name of her show.

Not what, anyhow, based in New York. Nice to have you back, Rachel.

Thanks for having me, Ira.

Nice to have you.

So all right, tell us about this new report, if you will.

Yeah, so, you know, as anyone who has been alive for, you know, this period of time might be aware,

the EDA has made a lot of progress cleaning up America's air since the mid 20th century.

Unfortunately, according to this new study, all of the increase in wildfire smoke

because of course wildfire seasons are growing longer

wildfires are becoming more common in more areas may have actually been
