The myths around London's tiniest sculpture

The Philpot Lane mice have been considered London's smallest sculpture for decades, delighting visitors and locals alike. But there's a common story told for why the unusual sculpture—which features two mice fighting for a piece of cheese—was placed there, saying it commemorated the death of a construction worker fighting over a lunch in the 1800s. The author of this article argues the evidence for such a story is lacking. Dive into the obscure history here.

Watch the safe way to remove a tick from your body

Minimizing your risk of Lyme and other tickborne diseases hinges on quickly removing ticks. To do so, place tweezers on the animal as close to the skin as possible and then pull directly upwards to try to avoid leaving bits of the tick's body behind. If possible, try to take a photo of the tick to share with your doctor to better identify potential disease risks (since certain tick species can carry specific diseases). Next, dispose of the tick without crushing it in your fingers—flushing it down the toilet, or placing it in alcohol or a sealed bag—and then thoroughly wash the bite area and your hands.

De-extinction techniques create new species from existing organisms

Rather than recovering a genetic sample of a lost species and editing it with that of living creature—as has been depicted in science fiction—scientists begin with living cells from close genetic relatives and use tools like CRISPR to swap in extinct versions of specific traits to create new hybrid species.
