Coral reefs are colorful underwater forests which teem with life and act as a natural protective barrier for coastal regions. The fishes and plants which call them home belong to some of the most diverse ― and fragile ― ecosystems on the planet. Higher sea temperatures from global warming have already caused major coral bleaching events. Bleaching occurs when corals respond to the stress of warmer temperatures by expelling the colorful algae that live within them. Increased levels of atmospheric carbon dioxide result in higher levels of CO² in the water, leading to ocean acidification, which is also a threat to coral. As the oceans become more acidic, the corals' ability to form skeletons through calcification is inhibited, causing their growth to slow. Increasing sea levels caused by melting sea ice could also cause problems for some reefs by making them too deep to receive adequate sunlight, another factor important for survival.

Comedian Janey Godley's tweets of a couple's train-bound row raise questions of how to protect our privacy in public places.
If the troubles of the two travellers had made it on to a newspaper first rather than a comedian's Twitter feed, would we be so relaxed about loss of privacy? I think perhaps not. Social media has done so much for freedom of expression, it would be cruel if it actually leads to less social freedom for fear of having our every misstep, angry word or misbehaviour broadcast there for all to see.

ZOMBIE NEUROSCIENCE
I don’t know if cockroaches dream, but I imagine if they do, jewel wasps feature prominently in their nightmares. These small, solitary tropical wasps are of little concern to us humans; after all, they don’t manipulate our minds so that they can serve us up as willing, living meals to their newborns, as they do to unsuspecting cockroaches. The story is simple, if grotesque: the female wasp controls the minds of the cockroaches she feeds to her offspring, taking away their sense of fear or will to escape their fate. What turns a once healthy cockroach into a mindless zombie it’s venom. Not just any venom, either: a specific venom that acts like a drug, targeting the cockroach's brain.
