SciShow News: New Elements and Exploding Whales

via scishow:

Hank introduces you to the latest element to be created — and explains why we make them in the first place — plus the science of exploding whales. It’s a thing, people. A messy, smelly thing.

Chemistry & Corpses: The Science of Bog Bodies

SciShow explains the chemistry, archaeology and history of bog bodies — naturally mummified corpses (and other fun things!) that have been discovered in Europe’s peat bogs.

Feather Shape, Chemistry Keep Diving Birds Dry

Feathers have long been recognized as a classic example of efficient water-shedding— as in the well-known expression “like water off a duck’s back.” A combination of modeling and laboratory tests has now determined how both chemistry and the microstructure of feathers allow birds to stay dry even after emerging from amazingly deep dives.

Popping Boba Balls - Cool Science Experiment

It’s a popular topping at your local frozen yogurt store… popping boba balls. But how to do make them? Our science guy, Steve Spangler, introduces us to a kind of food science that is sweeping trendy restaurants throughout the country.

Ice Cream Science

You’re probably craving ice cream to cool you down this summer. Reactions looks at the chemistry involved in making the treat creamy and sweet.

Turns out the creaminess of ice cream has little to do with cream. It’s all about the ice crystals. The smaller the crystals, the creamier the treat. We make ice cream three different ways with American University Assistant Professor Matt Hartings, and taste the difference.

The Cycle: Carbon and Oxygen and You

via jtotheizzoe:

This week’s It’s Okay To Be Smart video is about cycles.

This is a special one, and although you don’t get to hear my voice this week, you’ll find out about the connections between C, O, and you.

After you watch it, keep your eye out for a longer post coming up later today, explaining the beautifully simple cycles that these two atoms take through the biosphere. Watch here:

Why Does Bacon Smell So Good?

What is it about cooking bacon that makes it smell so good? The Reactions team puts its nose into everyone’s favorite breakfast food. We teamed up with the Compound Interest blog to break down the science of that sweet smell.

Turns out there are about 150 volatile organic compounds that contribute to bacon’s meaty aroma, many of them hydrocarbons and aldehydes, with some nitrogen-containing compounds thrown in for good measure.

Thanks to Andy over at Compound Interest: http://compoundchem.com/

Do Carbs Have Their Own Taste?

Carbs are delicious, and they give us a lot of energy. Do our tongues have a special receptor for tasting carbohydrates? Laci takes a look at a new study showing how our brain reacts when we eat carbs!

Molecule Enables Quick Drug Monitoring

Scientists have invented a molecule that can easily and quickly show how much drug is in a patient’s system. The molecule, now the basis of a start-up company, is expected to enable point-of-care therapeutic drug monitoring.

Turning wastewater into rainwater

A new cost-effective technology to treat mining wastewater and reduce sludge by up to 90 per cent has been used for the first time at a commercial mine. The technology, called Virtual Curtain, was used to remove metal contaminants from wastewater at a Queensland mine and the equivalent of around 20 Olympic swimming pools of rainwater-quality water was safely discharged.
