It's the world's biggest synchronised sex event that's OK to teach your kids about. Every year just after the full moon in late spring or early summer, the corals of the Great Barrier Reef release trillions of eggs and sperm into the water, usually over the course of about three or four nights. Despite the sheer scale of the event, scientists have only known about it since Before that, it was thought that corals brooded and released their fertilised embryos year round. But in the past 40 or so years, they've learnt a lot, and we've asked them to catch us up.

Social determination of sex in reef fishes
Jenny Mallon receives funding from the Coral Conservation Society. Coral reefs host a quarter of all sea species , but climate change, overfishing, and pollution could drive these ecosystems to extinction within a matter of decades. Marine biologists have been racing to restore degraded reefs by collecting corals from the wild and breaking them into fragments. This encourages them to grow fast and quickly produces hundreds of smaller corals which can be raised in nurseries and eventually transplanted back onto the reef. But if each fragment is an identical copy with one common parent, any resulting colony is likely to be genetically identical to the rest of the population. This matters — having a diverse range of genetically conferred traits can help insure reefs against disease and a rapidly changing environment. So what if scientists could use sexual reproduction in coral restoration projects?
Coral sex conceives new growth for the Great Barrier Reef
Information on the spatial ecology of reef sharks is critical to understanding life-history patterns, yet gaps remain in our knowledge of how these species move and occupy space. Previous studies have focused on offshore reefs and atolls with little information available on the movement and space use of sharks utilising reef habitats closer to shore. Cross-shelf differences in physical and biological properties of reefs can alter regional ecosystem processes resulting in different movement patterns for resident sharks.
Six and a half years after a year-old commercial sex worker was arrested for murdering a constable over his alleged blackmailing, a sessions court recently acquitted her for want of proof. Sex is a natural act of love between couples that is incomplete without deep feelings for each other. But what if your sex life is witnessing a lull where the action between the sheets is lifeless and thoroughly unimaginative. To battle this dry spell, a lot of modern couples are taking the recourse to watch sexually explicit videos in an effort to spice up their conjugal relationships.
