The omnipresence of PFAS—and what we can do about them
Per- and poly-fluoroalkyl substances (PFAS)—also known as "forever chemicals"—are everywhere. Created in the 1940s, these synthetic compounds are an unseen ingredient in many items that we use in our daily lives, like cleaning products, food pack.....»»
Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as "greener" and less smelly than solvent-based options. And they are often advertised as containing little-.....»»
Why we need to rethink what we know about dust
You may think of dust as an annoyance to be vacuumed and disposed of, but actually, on a grander scale, it is far more important than most people realize. Globally, dust plays a critical role in regulating our climate, radiation balance, nutrient cyc.....»»
Engineers "symphonize" cleaner ammonia production
Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the h.....»»
