Australians Cryogenically Freeze Coral Sperm From The Great Barrier Reef

[EmperorScorpious]

[quote]Well, that's one way to go about it. Over the past few weeks, Australian scientists have collected billions of sperm from spawning coral in the Great Barrier Reef, Australian news station ABC News reports. The sperm are to be cryogenically frozen, in case scientists want to rebuild parts of the reef in the future.

Since 1985, the Great Barrier Reef has lost more than half of its coral, one study found last year. The losses stem primarily from tropical cyclones, coral bleaching and predation by a certain species of starfish. Storms and coral bleaching will worsen with climate change.[/quote]

broadcast spawning is the funniest shit to explain to people.

Its cryonics. Cryogenics is the study of the production of very low temperatures and the effects they have. I know its not a big thing but I hate when news sources don't even bother to look up the right word.

It's like ejaculating into the wind hoping for the best! Except the females do it too. And somewhere down wind (or in this case, current) a new coral reef is born.

i'm curious, but someone explain to me how cryogenics work? do they just cool it to just above freezing?

Reproduction is a helluva lot more complex with different species more than simply freezing sperm and egg.
