Accepting his third annual Teacher of the Year award, Jeremy gazed out at an auditorium packed with wildly applauding children, parents, and colleagues. Silently he mourned. I was supposed to get my doctorate. I should be famous by now, not teaching fourth grade. I was supposed to have made earthshaking discoveries. It was expected of me. And I failed.

Development is typically thought to be a one-way street. Stem cells produce cells that mature into specific types, such as the neurons and glia that compose nervous systems, but the reverse isn’t supposed to happen. Yet researchers have now discovered nervous system cells transforming back into stem cells in a very surprising place: inside teeth. This unexpected source of stem cells potentially offers scientists a new starting point from which to grow human tissues for therapeutic or research purposes without using embryos.
With the announcement of an inquiry into the murder of Alexander Litvinenko, talk of poisons is back in the news. There are many articles with lists of the most poisonous substances, which are often gathered based on their acute toxicity as measured by something called LD50.
