Chemicals & Chemistry

Having Covid is a good excuse to bitch about...whatever. I chose digital thermometers. Hateful monstrosities.
Cannabis is a complex mixture of hundreds of chemicals. Here’s a look at one of them.
The New Lede — the Environmental Working Group's "investigative reporting" outlet — continues to mislead readers about pesticides. This time it’s spreading nonsense about a recent lawsuit challenging the EPA's assessment of the weedkiller glyphosate. Let's have a look.
China is 'seeding' clouds to increase rainfall and fight a severe drought. Will it work? A large body of research shows that soda taxes are ineffective, so why do public health experts continue to endorse them? Finally, has climate change increased the number of heart attacks we suffer? No.
There are thousands of chemicals, mostly dyes, used to create tattoos. Some of them are known carcinogens. Although the tattoo-cancer link is weak, people who are worried can get them removed. But the lasers that remove tattoos react with some inks and produce a different set of carcinogens—a strange but interesting problem.
Recent news reports alleged that new research has found a link between "forever chemicals" and liver cancer. This was an exaggeration of the results, to say the very least.
Much of the planet is now in the grips of a severe drought. This has prompted China to try cloud seeding to try to squeeze some water from the clouds. Is this real? Does it work? The Dreaded Chemistry Lesson From Hell is included at no extra charge.
The FDA has tried to fight opioid addiction by asking patients to mail their excess prescription pain meds to the agency for disposal. It's an absurd proposal. There's lots of anti-pesticide 'facts' floating around the internet; let's debunk the most popular of these claims.
A paper in the journal Science describes a new method for breaking down forever chemicals (PFAS), which, as their name implies are not so easy to destroy. Can this method be used to remove traces of these chemicals from our water? Or for anything else?
Similar to the Wizard of Oz, surprising facts are revealed when the curtain is pulled back on EPA’s PFAS Health Advisories. Why did EPA set protective “safe levels” against adverse outcomes not seen in the U.S. population? In this article, I will examine why EPA set the health advisories using methodology as they did, which I believe, allows scare tactics against PFAS to continue and flourish.
Activist groups like to use children's health as a bargaining chip in debates about pesticide safety. I'm a dad, and I call shenanigans on this disingenuous scare tactic.
If you're worried about Monkeypox, school shootings, car accidents, or any other possible threat to your health, stop this instant. The Environmental Working Group (EWG) has identified a greater risk for you to fret about—frozen pizza.
