Some say it’s the tap water, others say it’s the dough, and a few say it’s purely attitude. We dive into the chemistry of these tasty breakfast treats with the help of a top chef.

Here at Reactions, we ask the tough questions to get to the bottom of the biggest scientific quandaries. In that spirit, this week’s video explains why dogs sniff each other’s butts. It’s a somewhat silly question with a surprisingly complex answer. This behavior is just one of many interesting forms of chemical communication in the animal kingdom.

There’s nothing worse than reaching for a cold beer, taking that first sip and realizing your beer’s been skunked. Skunking is a chemical reaction that causes an awful, bitter taste. This week, Reactions explains why beers get skunky, and what you can do to keep your brews from going bad. Quick answer: it's all about light. Keep your beer in the dark, you won't have to worry about skunking.

We teamed up with mortician and author Caitlin Doughty (@thegooddeath) to demystify death and talk about what happens postmortem.

Pregnant women go through a lot to bring a baby into this world: 2 a.m. food cravings, hypersensitivity to certain smells and morning sickness, not to mention labor and delivery. In honor of Mother's Day, our latest video highlights the chemistry behind pregnant women's altered sense of taste and smell, how mom's diet influences baby's favorite foods and other pregnancy phenomena.
