Why don’t we have baby formula that’s just as good as breast milk? Sam chats with chemist Dr. Steven Townsend, who’s trying to figure out which sugar molecules in breast milk make it so unique and difficult to recreate in the lab. #breastmilk #babyformula #formula #milk For more about Dr. Townsend and his research, check out his C&EN Talented 12 profile: https://cen.acs.org/biological-chemistry/natural-products/Steven-D-Townsend/97/i33 You might also like: You Might Not Want to Mix These 5 Things With Birth Control https://www.youtube.com/watch?v=34tp9CCpOA0&list=PLtLT74crQcwV7Jr_KJJ7K8LgcW3LCP8u0&index=27 How Do Pregnancy Tests Work? youtube.com/watch?v=jc2_iBZ9r_k&list=PLtLT74crQcwV7Jr_KJJ7K8LgcW3LCP8u0&index=33 Why Do We Get Allergies? https://www.youtube.com/watch?v=vFZlxQU0Pyk&list=PLtLT74crQcwV7Jr_KJJ7K8LgcW3LCP8u0&index=30 Is Aspartame Safe? https://www.youtube.com/watch?v=vFZlxQU0Pyk&list=PLtLT74crQcwV7Jr_KJJ7K8LgcW3LCP8u0&index=30 Credits: Executive Producers: George Zaidan Hilary Hudson Producers: Andrew Sobey Elaine Seward Writer/Host: Samantha Jones, PhD Scientific consultants: Lelia Duman, PhD Brianne Raccor, PhD Steven D.

Cellulose is everywhere. In fact, it is the most abundant organic molecule on the Earth! It’s in (but not limited to) our food, clothing, and plastics, and the cellulose compound nitrocellulose is used in explosives but also in things like x-rays, early silent films and nail polish. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we get into how this tiny molecule holds up so much of our modern world.

It might feel like they’re making us cooler, but refrigerators and air conditioning are actually making our world warmer. Yes, they use a huge amount of electricity, but many older cooling methods also released tons of molecules that are still hanging around, shredding our #ozone layer. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we consider how we might keep ourselves and our food cool, without accidentally warming up our world.

On August 21, 1986, violent explosions rocked Cameroon’s Lake Nyos. A wave of water over 15 meters (around 50 ft) high flattened vegetation along the southern shore, but a second deadly, nearly invisible wave of carbon dioxide blanketed the nearby towns, suffocating residents and animals.

Sure, you’ve got a product that says “kills germs” under your sink, but will it really destroy the new coronavirus on surfaces? Turns out that if you’re using a disinfectant like a regular cleaner, you might not actually be disinfecting at all. To make sure you’re destroying 99.9% of viruses and bacteria, doing these three things is critical. And one quick note on EPA registration numbers: make sure to look for “EPA Reg No.” as there can sometimes be another EPA number on there as well. Then, enter the first two sections of the number into List N to find the product. (If you enter the third part, the search won’t work properly.) Some products only list the first two parts.

Many people are wondering if that bad cold they had back in February or March was actually the new coronavirus. In principle, an antibody test could tell you that, but most of the tests out there right now aren’t very good. We chatted with David Kroll to learn how these tests work, where they go wrong and why a test that’s 96% accurate is actually pretty bad. #coronavirus #immune. #antibodytest You might also like: Could the Polio Vaccine Save the World (...Again) https://youtu.be/Wqw4aX4c33c How Much Do Cloth Masks Protect You From Getting the Coronavirus? https://youtu.be/knCseXki4gE Coronavirus Vaccine: Where Are We and What's Next?: https://youtu.be/gDY8pH6OWBc Can Soap REALLY "Kill" the Coronavirus?: https://youtu.be/K2pMVimI2bw Why Do We Get Allergies?: https://youtu.be/vFZlxQU0Pyk Credits: Executive Producers: George Zaidan Hilary Hudson Producers: Andrew Sobey Elaine Seward Writer/Host: Samantha Jones, PhD Scientific consultants: David Kroll, PhD Brianne Raccor, PhD Michelle Boucher, PhD Special Thanks: Ruben Rodriguez Sources: Insight into FDA’s Revised Policy on Antibody Tests: Prioritizing Access and Accuracy https://www.fda.gov/news-events/fda-voices/insight-fdas-revised-policy-antibody-tests-prioritizing-access-and-accuracy?utm_campaign=Insight%20into%20FDA%E2%80%99s%20Revised%20Policy%20on%20Antibody%20Tests%3A%20Prioritizing%20Access%20and%20Accuracy&utm_medium=email&utm_source=Eloqua EUA Authorized Serology Test Performance https://www.fda.gov/medical-devices/emergency-situations-medical-devices/eua-authorized-serology-test-performance CDC: Serology Testing for COVID-19 https://www.cdc.gov/coronavirus/2019-ncov/lab/serology-testing.html Coronavirus: surprisingly big problems caused by small errors in testing https://theconversation.com/coronavirus-surprisingly-big-problems-caused-by-small-errors-in-testing-136700 Antibody Test, Seen as Key to Reopening Country, Does Not Yet Deliver https://www.nytimes.com/2020/04/19/us/coronavirus-antibody-tests.html Prominent scientists have bad news for the White House about coronavirus antibody tests https://www.cnn.com/2020/04/14/health/coronavirus-antibody-tests-scientists/index.html The FDA Said It Will Now Crack Down On Shoddy Coronavirus Antibody Tests https://www.buzzfeednews.com/article/stephaniemlee/coronavirus-fda-antibody-tests-accuracy F.D.A.

When you die, there are a lot of things you can do with your dead body--embalm it, cremate it, donate it to science (the list goes on…), but some people will choose to have their dead bodies, or body parts, frozen until the technology of the future has (hopefully) advanced enough to bring them back to life.

Are Vampires Real? Of Course Not, But . . . Are Vampires Real? Of Course Not, But . . .

Check out Monstrum: https://www.youtube.com/channel/UCO6nDCimkF79NZRRb8YiDcA Halloween season wouldn’t be what it is without the undead. This week on Reactions, we unpack the chemistry that may have inspired one of our favorites: the vampire. When you think “vampire” some of today’s most popular vampires might come to mind. Attractive bloodsuckers with pale, sometimes sparkling skin. But in the 18th and 19th centuries, when European vampire lore first really took off, they were a bit more...morose and, instead of that crystal-clear skin, they appeared kind of sickly with a reddish complexion. Vampires were often depicted as men from poor, rural areas, who, after dying--often from diseases like the plague--would emerge from their coffins to wreak havoc on a nearby town, sucking the blood of humans, turning them into vampires as well. So how did this folklore come about? Possibly...disease.
