A recent study in the journal Thorax has explored a link between hay fever and being exposed to prenatal pollutants. The findings are pretty surprising. The body of research on the topic isn't as large as it should be, but the study hopes to present conclusions based on a large sample size of subjects.

From a consumer perspective, solar power is still an up-and-coming challenger to the existing fossil fuel infrastructure that most power generation systems take advantage of. The University of Michigan estimates that as little as 1.8% of US power generation in 2019 came from solar sources. Part of the reason this number is so low is why more commercial users haven't tapped into the technology. It makes little sense to go to the expense of installing a solar generation system based on the returns that it offers. However, that may soon change, based on new advances in technology.

Artwork is one of the newest purchasable commodities on the crypto market, thanks to a new technology known as non-fungible tokens (NFTs). NPR informs us that an NFT is a crypto token that isn't interchangeable but is tied to a specific commodity. The easiest way to think about them is an analog to how they're being used. For the first time in its history, blockchains can be used to hold and trade collectibles. Yet, the trade of these collectible tokens brings with it some alarming environmental concerns.
