From phytochemicals to recipes: health indications and culinary uses of herbs and spices https://www.diningandcooking.com/2097430/from-phytochemicals-to-recipes-health-indications-and-culinary-uses-of-herbs-and-spices/ #Chemistry/FoodScience #diseases #FoodMicrobiology #FoodScience #general #nutrition #PlantSciences #Recipes #RecipesTopics
Since I was a child my favorite #books have been dictionaries — they’re reliable, vetted sources of definitive information which enable #education, empower #knowledge, and inform #communication.
As a professional #actor and #soprano, I regularly use dictionaries of all sorts to ensure my comprehension, presentation, and pronunciation of texts is both accurate and precise. (Thanks #AP #chemistry for teaching me the difference between these terms. 
)
Today in the classroom:
First year chem is doing a "memory box" activity over this semester's topics. The re-read each unit intro and reflect on the standards practiced. They then summarize in words, pictures, and other symbols the main ideas on a sheet of paper to create an interconnected concept map, showing relationships.
Second year chem is going to try out a new spectroscopy lab for me and give feedback on the procedure, questions, and analysis items.
oolonek reminded me how cool IDSM is (see https://doi.org/10.1186/s13321-021-00515-1) and works wonderfully in the rich chemistry SPARQL world (see https://doi.org/10.1186/1758-2946-3-15).
Here I mashed up @wikidata, IDSM, QLever, @cdk Depict, and Ammar Ammar's SNORQL UI, all open science
Yes, I need to add this to our @wdscholia Chemistry preprint (https://doi.org/10.26434/chemrxiv-2025-53n0w)
Looks like we're on the brink of a breakthrough. And it’s about chili peppers 
Capsaicin and dihydrocapsaicin finally have chemical antidotes: capsianoside I et. al (pictured). These compounds dramatically reduce mucosal irritation when co-applied with chili actives
This could mean a real shift in how we protect civilians. Most crucially, these compounds offer the first true chemical countermeasures to pepper sprays and tear gas
The Strange Surface of Tea: Exploring the Colloid Chemistry Behind the "Tea Film"
TechText 7 results are in. My article on the colloid chemistry of tea film won on HABR.COM, the top tech platform in the post-USSR space. Stoked!

How uroshiol, the irritant in poison ivy, and Tylenol are both non-toxic until they aren't:

American Council on Science and HealthPoison Ivy is Poison For the Same Reason Tylenol is ToxicSummer’s almost here, and that means nuisances: mosquitoes, poison ivy, and visiting relatives. Two cause itching, one causes emotional damage, and it doesn't respond to bug spray. But only poison ivy unleashes a chemical weapon sneaky enough to trick your immune system into attacking your own skin. And if that gives you a headache? You could try Tylenol, which, fun fact, is toxic for the same reason poison ivy is. Huh?
Enteric coated tablets, also called gastro-resistant tablets, have delayed-release features.

Less than 10% of Global Plastics manufactured from recycled Materials.
The findings, reported in Communications Earth & Environment, are part of a comprehensive analysis of the global plastics sector, which also reveals a large increase in the amount of plastic being disposed of by incineration and substantial regional differences in plastic consumption.

Global plastic cycles in 2022.
Of the 400 million tons of plastic produced over the year, just under 38 million tons [9.5%] were produced from recycled plastic. Some 98% of the remaining 362 million tons were produced from fossil fuels, predominantly coal and oil.
Around 268 million tons of plastic was disposed of over the year, with only 27.9% sent for sorting and potential recycling [36.2% was instead sent directly to landfill and 22.2% was sent directly to incineration]. Additionally, only half of the sorted plastic was actually recycled, with 41% of the sorted plastic instead incinerated and 8.4% sent to landfill.
However, the total percentage of global plastic waste sent to landfill in 2022 (40%) has still decreased significantly compared to the estimated 79% of all global plastic waste sent to landfill between 1950 and 2015. The U.S. had the highest per capita plastic consumption, with an average of 216 kg of plastic consumed per person per year, while China consumed the most plastic overall [80 million tons per year].

Today in the classroom:
First year chem is producing brass pennies. It combines redox, solutions, and mixtures into a nice, all-in-one lab.
Second year chem had a good day yesterday playing with slime (polymers) and a cornstarch/water suspension (non-Newtonian fluid). Today will be a make up day for labs/tests, etc.
Why not make use of the available space?
