What Science Says About Brining Your Bird Reactions 2022-11-23 | George and Andrew violently disagree on whether brining meat matters. George thinks brining is totally unnecessary; Andrew thinks George is a heathen. They resolve their dispute with the help of some chemistry, a blind tasting, and DC’s very own Roaming Rooster.

Is DNA the Future of Data Storage? Reactions 2022-10-26 | Could the future of data storage be DNA? It’s the original format after all, storing the information needed to build every living thing. and it has a handful of qualities that would make it perfect to store all the digital information in our world. With recent advances in DNA sequencing and DNA printing, it’s technically possible. But there are a few obstacles to overcome before this sci-fi sounding tech can become a household reality.

Why Does Salt Change the Taste of Everything? Reactions 2022-09-29 | If your coffee is too bitter, add a pinch of salt. If your salad isn’t sour enough, add a pinch of salt. If your beer is too bitter, add a pinch of salt. Salt has a seemingly magical ability to enhance good flavors and dampen bad ones.

How Roundup Kills Weeds (And How Weeds are Fighting Back) Reactions 2022-09-14 | In 1997 there were 432 new patents for herbicides, by 2009 there were only 65. The development of broad spectrum glyphosate and “Roundup Ready crops” was a game changer that worked so well people basically stopped looking for new herbicides. That is until the weeds started fighting back.

How Quinine Fights Malaria, and How That Caused* World War One Reactions 2022-08-10 | Can a medicine cause a war? When chemists isolated a new compound from the bark of a South American tree, they had no idea they were changing world history, and cocktails, forever. If we look at how the bark of the cinchona tree is used to treat malaria, we can see cutting edge chemistry showing quinine binding to an enzyme that is essential for the malaria parasite’s survival. But if we look from another angle, we can see how that coincidental affinity may have been a major contributing factor to World War One.#malaria #medicinalchemistry #historyCheck out the new shows on PBS Terra:Why Am I Like This: youtu.be/eWzBNfBnFysFar Out: youtu.be/jpUjze3v_6c You might also like:What Happens When You Distill Whiskey?youtu.be/a1IruS1bKN8 The Science of Maple Syrup Production:youtu.be/nSRCDiKMEJc How Lead (Maybe?)

SPACE TRASH! ft. Chemistry Reactions 2022-07-13 | Remember when Elon Musk launched a car into space? It’s not just peacefully drifting through a vacuum–it’s hurtling around the sun at 63,592 mph, being bombarded by solar radiation. It might be in pieces.But, not the same pieces it would be in if it was down here on Earth. The environment of space breaks it down differently. And the space debris a little closer to us, all the stuff that we humans have sent into space and just left there to orbit us? The unusual environment of space means it too breaks down and degrades differently than it would down here on earth. But… how long does it take to break down? Does it all break down? And how is that car looking right about now…You might also like:We Are Made of "Star Stuff"youtu.be/2bm479V8qPs Challenger: The Real Story of an Avoidable Disasteryoutu.be/uI174WMnWl4 What Do Astronauts Do With Pee in Space?youtu.be/w6x54zYuqXk What Does the Moon Smell Like?youtu.be/iQod_oYnFTc What Could An Explosion On the Sun Do Here On Earth?youtu.be/i7mZBaleCFE Credits:Executive Producers: Matthew RadcliffProducers: Elaine Seward Andrew Sobey Darren WeaverWriter/Host: Alex Dainis, PhDScientific Consultants:Michelle Boucher, PhDJohn Crassidis, PhD; Jer Chyi (J.-C.)

How is Whiskey Made? A Deeper Dive Into Distilling. Reactions 2022-06-15 | Have you ever wanted to make your own bourbon? Don’t! The process might be relatively simple- heat a fermented liquid and keep only the boiled alcohol – but it is dangerous and illegal without a license. This video discusses how to separate one type of liquid from a slurry of others through boiling points and the intermolecular forces that influence them.#whiskey #distilling #chemistry You might also like:The Science of Kombucha:youtu.be/YxARRckS9dA Better Pizza Through Chemistry:youtu.be/m30YnuF9vUc Making Drinking Water From Sewage:youtu.be/X9fAoyjjX6M Why They Don’t Make Grade B Maple Syrup Anymore:youtu.be/nSRCDiKMEJc Credits:Executive Producers: Hilary Hudson Producers: Elaine Seward Andrew Sobey Darren WeaverWriter/Host: Sophia RobertsScientific consultants:Leila Duman, PhDWilliam Parsons, OhDBrianne Raccor, PhD James Chickos, PhDSources:Distillationchem.libretexts.org/Ancillary_Materials/Laboratory_Experiments/Wet_Lab_Experiments/Organic_Chemistry_Labs/Misc/Distillation 2.2:Distillationchem.libretexts.org/Bookshelves/Organic_Chemistry/Book%3A_How_to_be_a_Successful_Organic_Chemist_(Sandtorv)/02%3A_COMMON_ORGANIC_CHEMISTRY_LABORATORY_TECHNIQUES/2.02%3A_Distillation Distillationchem.libretexts.org/Ancillary_Materials/Laboratory_Experiments/Wet_Lab_Experiments/Organic_Chemistry_Labs/Misc/Distillation 10.22: Distillationchem.libretexts.org/Bookshelves/General_Chemistry/Book%3A_ChemPRIME_(Moore_et_al.)/10%3A_Solids_Liquids_and_Solutions/10.22%3A_Distillation 3.S: Functional Groups (Summary)chem.libretexts.org/Courses/Georgia_Southern_University/CHEM_1152%3A_Survey_of_Chemistry_II_(GSU_-_Dr._Osborne)/03%3A_Organic_Nomenclature_-_Functional_Groups/3.S%3A_Functional_Groups_(Summary) 8.14: Alcoholschem.libretexts.org/Courses/University_of_North_Texas/UNT%3A_CHEM_1410_-_General_Chemistry_for_Science_Majors_I/Text/08%3A_Properties_of_Organic_Compounds/8.14%3A_Alcohols 2.11: Intermolecular Forces and Relative Boiling Points (bp)chem.libretexts.org/Bookshelves/Organic_Chemistry/Map%3A_Organic_Chemistry_(Wade)/02%3A_Structure_and_Properties_of_Organic_Molecules/2.11%3A_Intermolecular_Forces_and_Relative_Boiling_Points_(bp) Distillationchem.libretexts.org/Ancillary_Materials/Laboratory_Experiments/Wet_Lab_Experiments/Organic_Chemistry_Labs/Misc/Distillation Overview of Distilled Spiritspubs.acs.org/doi/abs/10.1021/bk-2019-1321.ch011 6 - Chemical Constituents of Grapes and Winesciencedirect.com/science/article/pii/B9780123736468500093

Better Pizza Through Chemistry Reactions 2021-09-29 | This week we show you how two simple changes can turn cardboard-y pizza into award winning pie (okay, award-winning might be a slight exaggeration, but we awarded ourselves a win, so deal with it). Here’s our simple recipe for making stellar pizza at home:Mix 1 package (0.25 oz) of dry yeast into 1 cup of warm waterLet sit for 5 minutes.Add 2.5 cups of bread flour and 1 tsp of salt. Mix.Knead the dough for a few minutes.Dust your hands with flour and form your pizza dough into a round ball. Transfer to a bowl.Let the dough sit, covered, in the fridge overnight. THIS IS KEY! Remove the dough from the fridge, let sit at room temperature for 30 minutes, then using your hands or a rolling pin spread out the dough.Set your oven as high as it can go (for many ovens that’s 550 degrees F)Add sauce and toppingsPut your pizza in the oven until the crust starts to brown (should be around 9 minutes, maybe a little longer if you like it crispy!)Let cool and enjoy!You might also like:The Science of Kombuchayoutube.com/watch?v=YxARRckS9dA We Found The Best Hot Pepper Cure (It’s Not Milk)youtube.com/watch?v=8R98O29Fs7s How Milk Becomes Cheeseyoutu.be/uJEkb4Hq5jY We 🔥Burned🔥 Food to Figure Out How Many Calories It Has:youtu.be/ahvE5kuWcps Credits:Executive Producers: George Zaidan Hilary Hudson Producers: Elaine Seward Andrew Sobey Darren WeaverWriter/Host: Sam Jones, PhDScientific consultants:Michelle Boucher, PhDEmily Jane Buehler, PhDBrianne Raccor, PhDPeter Reinhart Sources:The Bread Baker’s Apprenticebarnesandnoble.com/w/the-bread-bakers-apprentice-15th-anniversary-edition-peter-reinhart/1123130134Baking Bread: The Chemistry of Bread-Makinghttp://www.compoundchem.com/2016/01/13/breadThe chemistry of pizzaacs.org/content/acs/en/pressroom/reactions/videos/2014/the-chemistry-of-pizza.htmlThe science and magic of breadmakingtheguardian.com/science/blog/2009/nov/26/science-breadmaking Bread Science: The Chemistry and Craft of Making Breadtwobluebooks.com/books [Excerpt] Bread Science: The Chemistry and Craft of Making Breadtwobluebooks.com/wp-content/uploads/2017/01/Excerpt-BreadScience.pdf

How Lead (Maybe?) Caused the Downfall of the Roman Empire Reactions 2021-06-23 | Ancient Rome’s emperors did some pretty bizarre stuff—bursting into uncontrollable fits of laughter, appointing a horse as a priest, dressing in animal skins and attacking people… the list goes on. Why did they act this way? Possibly… lead poisoning. In this week’s episode, we unwrap the possibility that lead caused the Roman Empire’s collapse.
