How stunning 19th century dyes led to today's drugs

In 1856, after yet another day of disappointing experiments, a chemist named William Henry Perkin was cleaning up his glassware when he made a discovery that would harken a new — and colorful — era of science and industry. Just 18 years old, Perkin was a promising young student in a prestigious lab at the Royal College of Chemistry in London and he was supposed to be figuring out a way to make a chemical compound called quinine. Despite his best efforts, Perkin was coming up empty — or rather — producing a lot of dirty dishes with little to show for it. But he did notice that there was a curious goop in one of his flasks, and it turned a brilliant shade of purple in the wash. Intrigued, Perkin decided to try dyeing a swatch of silk with his serendipitous solution. Although he had failed yet again to produce quinine, Perkin had created the very first synthetic dye and launched a scientific industry that is still bringing new drugs and dyes to market today.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

De-extinction: Genetics, conservation, and lessons from 'dire wolves'

Back in April, a company called Colossal Biosciences announced that they had brought dire wolves — ancient canines of Game of Thrones fame — back from extinction. The internet went wild. But while some media outlets proclaimed the return of a long-gone species, many scientists shot back on social media that these weren’t really dire wolves, they were just genetically engineered grey wolves. Suddenly everybody had an opinion on what de-extinction is, what it is not, and whether or not we should be doing things like this in the first place. In this episode, we talk to scientists who have been working in this area for a while, and they not only share their thoughts on these wolves — they completely change our understanding of the term “de-extinction.”Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

Zircon: How this tiny, ancient mineral is upending what scientists believed about early Earth

How did the early Earth, over four billion years ago, evolve into the planet we know and love today? It’s a big question, and an open question. To get answers, geologists turn to a surprising source — a tiny mineral no bigger than the diameter of a human hair, that has secrets about our planet locked away in its crystal structure. This miniscule mineral, with its big stories is called zircon.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

[BONUS] Biodegradable super glue and a severe greenhouse gas that lowers your voice: Tiny Show and Tell Us #30

In this episode of Tiny Show and Tell Us, we talk about a new and exciting biodegradable polymer that seems to outperform commercial super glues. Then we discuss a compound called sulfur hexafluoride (SF6) that is used in high voltage equipment. Not only is SF6 a potent greenhouse gas, if you breathe it in it has the opposite effect of helium — it makes your voice deep. But it can also lead to asphyxiation so you should not breathe it in. We repeat: do not breathe this gas in.  We need your stories — they're what make these bonus episodes possible!
