Explosive sex, coral killers, room for shrooms and more

This week the Alchemist discovers that carbon dioxide could pose a serious threat to marine life and in particular corals and the marine ecosystems that depend on them. We also find out how publication of new rigorous research into the effects of “shrooms” could represent a watershed moment in understanding hallucinogens. Solving the problem of soliton structure is set to lead to new types of actuators and fine control for artificial muscles and TEM stacks up carbon nanotubes for peak-time viewing. Finally this week, explosive sex in a tube. But, you’ll have to wait till at least 2008.
