Take PBS' audience survey: https://to.pbs.org/2024SurveyReax Kidney stones are the worst so I made some at home and tested supposed prevention methods to hopefully keep them at bay. Citrate is what doctors recommend to prevent them but how is a little lemon in your water going to stop them from forming? And are all citrus juices the same or does orange juice prevent kidney stones more than lemon juice or even grape juice? This week Alex gets the answers. #kidneystones #citrate #oxalicacid #experiment Credits: Executive Producer: Matthew Radcliff Producers: Andrew Sobey Elaine Seward Darren Wea ..read more

That’s right, every other video you’ve seen about color has been wrong, or, at least, incomplete. Because they pretty much all say that when light hits an object, some is absorbed, whatever isn’t is reflected back, and that’s what we perceive as color. But absorption is not the whole story. This video is going to explore deeper than all those other videos. It’s going to explain that color is the result of light interacting with electrons … most of the time. #color #electrons #electronorbitals Credits: Executive Producer: Matthew Radcliff Producers: Andrew Sobey Elaine Seward Darren Weaver Writ ..read more

This was testing the L-methamphetamine inhaler directly, not after metabolism, so maybe the test can distinguish between the metabolites but not the drugs themselves? If you have any other guesses, let us know. #organicchemistry #pharmacology #scienceshorts ..read more
