Can you use a Dreaded Chemistry Lesson from Hell (TM) to take your mind off your woes? If so, dive right in.
Chemicals & Chemistry
A Seattle area company is selling a dilute solution of bleach and pretending that it has a world-changing technology to rescue us from COVID.
The anti-chemical Environmental Defense Fund claims that there are 10,000 chemicals in food that should be tested and regulated. It's a silly idea. Here's why.
The anti-chemical Silent Spring Institute has commissioned a ridiculous study, one that reaches a conclusion akin to pointing out that a circle is round. It's a bunch of nonsense. Here's why.
Plastic bottles litter most of the world. There have been ongoing efforts to find methods to biodegrade PET, a very common plastic used for bottled water. British scientists have discovered an efficient way to get bacteria to "eat" PET plastic. Here's how it works.
Things pretty much suck. Three states are on fire. There are five tropical cyclones in the Atlantic for the first time ever. Our social fabric is hardly intact. And there is this annoying little virus blowing up people's lungs -- and it isn't going away anytime soon. But, thanks to the CPSC at least we can sleep at night. Dr. Duck's lead buttons will threaten us no more.
Welcome to the 15th Dreaded Chemistry Lesson From Hell. This time you will be (mis)treated to a plethora of knowledge about bismuth - information so critical that it would be hard to imagine surviving the day without it. And reader comments from Joe, the ball bearing salesman, and Candy, a decertified yoga instructor. Could there be a better way to start your day?
A large study just found that there was little, or no, evidence of cancer linked to the use of hair dye. But one of the most common dyes, para-phenylenediamine, could be reasonably expected by a chemist to be carcinogenic because of the conditions used in the dying process. Even though it's not. Here's why.
Navalny, a Russian anti-corruption activist and well-known critic of President Vladimir Putin, is being treated in Germany for an apparent case of poisoning by an "organophosphorus neurotoxin." But which one: the insecticide or the chemical weapon? Here are some clues.
The most recent workshop of the Beyond Science and Decisions series was conducted at the National Institute for Occupational Safety and Health (NIOSH) in Cincinnati, Ohio, in February of this year.
GHB, one of the "date-rape drugs," is being increasingly abused after two decades of low usage. Here's a lesson on the chemistry, biochemistry, and nomenclature of the drug. Admittedly, this sounds deadly boring. But there's more. Juvenile puke humor! Enjoy.
