"In a first-of-its-kind study, a team of environmental engineers from the Cockrell School of Engineering at The University of Texas at Austin found that infants are exposed to high levels of chemical emissions from crib mattresses while they sleep.

Analyzing the foam padding in crib mattresses, the team found that the mattresses release significant amounts of volatile organic compounds (VOCs), potentially harmful chemicals also found in household items such as cleaners and scented sprays."—Cockrell School of Engineering

Very excited to read this recent #tea research paper. It's basically where I would have gone next if I'd kept on with tea research after my PhD (based on the title and abstract, at least). I'll *try* to find time to write a plain-English summary as a thread here when I get a chance to read it.

Changes in volatile compounds in withering tea leaves after infestation with tea green leafhopper (Empoasca onukii Matsuda)

The effects of withering, cultivar yellowing, and Empoasca onukii infestation on tea leaf aroma have each been characterized, but variations in volati…
