We're open to your questions on the Naked Scientists this week, finding out how photosynthesis works underwater, exploring the sex lives of barnacles and discussing if rockets punch holes in the ozone layer. Plus, a viral cause of hypertension, how bees stick to petals like velcro, and a new, super-dense deuterium - 130,000 times denser than water! We hear about the new generation of eBook readers, and in Kitchen Science Dave vacuums his bathroom scales to weigh the air! Like this podcast? Please help us by supporting the Naked Scientists
