70% higher risk is meaningless if you don't give the absolute risk. Common issue with this kind of reporting... EDIT: my bad, they did talk about the absolute risk later on. Should have been the first thing they mention, though, to avoid looking sensationalist. > The researchers calculated the rate of Parkinson’s disease in the veterans and compared it with the rate in more than 72,000 veterans who lived at Marine Co…

Is that the only data sets they looked at? Comparing only two locations means that there could be any number of site differences that account for the difference in the rate of Parkinson’s disease, other than the studied chemical.

Of course clickbait because you need to click to get the name.

Yeah, because if you had the name you'd have no further questions. There's just no way to condense enough important information into the headline, and the chemical name would mean nothing for 99% of people.

If I already know TCE is dangerous and need to be avoided I might not need to read the article or I could if I need further information.

But if I need to click to get the basic information it's clickbait.

>"But in the 20th century, TCE was used for many purposes, including making decaffeinated coffee" ...

This is exactly the reason I never touched decaf coffee until I found Swiss water process (SWP) decaf. It never made sense to me to use hydrocarbon solvents in a food application

Why would you drink coffee if not for the caffeine. It's not exactly the most delicious drink.

I don't understand this - If you don't enjoy the experience of drinking coffee, and just want the caffeine, then why not just take a caffeine pill?

Caffeine pills it's a bit easy to unconciously take too much and get all jittery, and it's not really spread out enough.

Optimal consumption of caffeine seems to be a decent-sized initial intake, then smaller doses over time to maintain (eg take a few more sips). There's no good way to do that with pills.

Is there any evidence it actually reduces those risks, or is it speculation?

Mitochondrial disfunction is the basis for a huge number of cancers. See “Tripping over the Truth: The Metabolic Theory of Cancer”[0] for a good history of it. [0] https://www.goodreads.com/book/show/23496164

If you have the name you can start searching for things that has it right away.

Widely used chemical *(that was generally phased out in the 70s) linked to Parkinson's. Still important, but you don't need to start searching product labels in 2023 for it.

Some of the most populated zones of the Bay Area are built on top of superfund sites, which have high concentration of TCE underground. https://www.epa.gov/superfund-redevelopment/superfund-sites-...

This map (from 2015) shows sites with the most TCE groundwater contamination. Bay Area is actually quite clean. LA is completely fucked though

That chemical is trichloroethylene. Even Science does clickbait now.

There are two other issues with this...

1. The authors only studied two military camps. One with high TCE levels, and one with low TCE levels. But, obviously, there might be any number of other factors that are different between the two camps with a causal relationship to Parkinson's Disease.

2. There is an active class action lawsuit from this military camp. Doing a limited study that benefits one side of a class action lawsuit should always be taken with some extra skepticism and evaluated for conflicts of interest.

This is Hacker News, so you should probably include a "/s" to indicate sarcasm, because otherwise you'll get a lot of people agreeing with you.

I would say yes few would agree but fortunately HN is still not filled with late stage capitalist idiots.
