Testing the sound mirrors that protected Britain

Testing the sound mirrors that protected Britain

I very rarely link to (or even watch) a video. But I am happy to make an exception for Tom Scott’s excellent entertaining and educational videos.

Here, he tests concrete sound mirrors with drones. I’m fascinated by sound mirrors — an early 20th century technology designed to provide early warning of approaching aircraft, which became obsolete quickly as aircraft speeds increased, and radar took over.

Scientists have revived worms that had been frozen for 42,000 years

Scientists have revived worms that had been frozen for 42,000 years

The worms, known as nematodes or more commonly as roundworms, had been frozen for up to 42,000 years, since a time when much of the planet was covered in ice.

But they weren’t dead — just cryogenically preserved.

The researchers brought the worms back to a lab, where they slowly thawed them over several weeks.

  1. This is cool.
  2. We’re all going to die!

The shoey: Why it’s a bad idea to copy Daniel Ricciardo’s F1 podium ritual

The shoey: Why it’s a bad idea to copy Daniel Ricciardo’s F1 podium ritual)

Finally, someone has done the science on the shoey, the ritual whereby Daniel Ricciardo drinks champagne out of his sweaty shoe after winning a grand prix. It’s about as bad as you might expect.

The positive — and possibly surprising — revelation was that in most instances the alcohol kills much of the bacteria present.

In fact, the only drink that failed to do so was sparkling white wine or champagne. Not only did the fizzy stuff fail to act as a disinfectant, but it encouraged the growth of more bacteria — and we’re not talking the friendly kind.

Food (or drink) for thought when champagne is the go-to tipple for Ricciardo when he celebrates a F1 podium finish.

Via WTF1.
