SoT 206: Jellies All Day Long

Hosts: Ed Brown, Penny Dumsday, Lucas Randall.

The first case of a human falling ill from cancer cells contracted from a parasitic tapeworm has been reported in Columbia.

And in an unrelated story, a Californian man has had a live tapeworm removed from his brain in a potentially life-saving operation.

The Rosetta probe orbiting 67P/Churyumov–Gerasimenko has surprised everyone by detecting large amounts of molecular oxygen on the comet. The finding suggests molecular oxygen was present when the comet was formed soon after the birth of the solar system, 4.6 billion years ago.

Stanford University researchers have discovered how jellyfish actually swim – and it’s not how previously thought. They make a region of low pressure ahead of themselves, essentially sucking themselves forward. Lucas mentions Smarter Every Day’s video of a balloon in a car.
