This week, mind reading children, scientists find a new gene in the lung cancer cocktail, and satnav or map-nav - what's greener? Plus we become biological weapons inspectors and explore nature's arsenal of venoms, poisons and toxins, including a scorpion's sting that can highlight cancer, how funnel web spiders are helping farmers fight off insect pests, the marine cone snail that harbours a painkiller ten thousand times more powerful than morphine, and how a snake bite can help to prevent a heart attack. Meanwhile, in Kitchen Science, Ben samples a more everyday toxin - by making stinging nettle tea.
