The persistence of smoke VOCs indoors: Partitioning, surface cleaning, and air cleaning in a smoke-contaminated house | Science Advances

Many volatile organic compounds (VOCs) persisted days following the smoke injection, providing a longer-term exposure pathway for humans….These rates imply that vapor pressure controls partitioning behavior and that house ventilation plays a minor role in removing smoke VOCs. However, surface cleaning activities (vacuuming, mopping, and dusting) physically removed surface reservoirs and thus reduced indoor smoke VOC concentrations more effectively than portable air cleaners and more persistently than window opening.

November 28, 2024Variation in human water turnover associated with environmental and lifestyle factors | Science

QT:{{”
….Okay. So when you got measurements from this big group
of people, you end up
with kind of a range of water turnover and it varies by person and location. So how does this range
that you measured in this diverse group of people? How does it stack up with eight, eight ounce
glasses a day, which is like two liters of water a day, that recommendation we discussed?
Most people are not going to need to drink, eight
glasses of water a day, two liters of
water a day. If you measure how much water flows through your body, how much water comes in
and goes out every day, there’s a lot of variation, but it’s something like three to four liters a day
total. And that includes not just the water that you drink, but that includes the water that’s in the
food that you eat.

Testing planetary defenses against asteroids, and building a giant ‘water machine’ | Science | AAAS

Thought the recent @ScienceMagazine podcast about the asteroid deflection mission dealt well with the effect of science on
sci-fiction and *vice-versa*. Wonder if this interplay happens in other scientific contexts?
Chewing burns more calories than you think—and may have shaped our evolution | Science | AAAS
August 28, 2022https://www.science.org/content/article/chewing-burns-more-calories-you-think-and-may-have-shaped-our-evolution Great article! Wondered about the implications of chewing for weight loss: Perhaps humans so readily “overeat” because they don’t have to spend so much time chewing.
