Chemistry is a fascinating subject, but usually it gets a bad rap. Still, chemistry affects almost every aspect of our lives -- even though most people don't think about it that much. Here are some interesting chemical discoveries that have made it into the news recently. Any reactions?
- A rare form of sulfur in the Earth's mantle could explain how gold mineral deposits form and shed more light on early Earth geochemistry. Even though this discovery is about chemistry in the depths of the Earth, it could also change how we describe the composition of the Earth's ancient atmosphere. [url]
- Helium might be the second most abundant element in the universe, but its supply on Earth isn't inexhaustible. And a particular isotope, helium-3, might be getting quite expensive in the near future (until nuclear chemists figure out a cheaper way to make more). [url]
- When hair products say they're formaldehyde-free, someone should double check for formaldehyde precursors. When formulation chemists find ingredient loopholes, watch out! [url]
- An environmental group claims that BPA-free containers can still leach out chemicals with "estrogenic activity" under normal use conditions. But there are a lot of chemicals that might exhibit "estrogenic activity" -- and be perfectly harmless at low concentrations. [url]
