[UPDATE 6 p.m.] Immune cells that protect us from the dangers of this microbe planet are behind this year’s Nobel Prize in medicine. Two of the three winners discovered receptor proteins that can recognize microbial invaders, activating the innate immune response. The third discovered dendritic cells, which serve as surveillance cells and can switch on the body's adaptive immune response.
Researchers at North Carolina State University have found a surprising potential weapon against the conjectural "biological terrorism" of the imminent future. Sorry, what's that? We have self-inflicted domestic dangers on our hands that are more real and pressing than... terrorism? How things change. In any case, if suspicious white powders do happen to show up in your mailbox, you'll be prepared to defend yourself against them. It'll be as simple as crushing a pill and stirring it up in yogurt. Just like Mom used to make. Or something like that.

1. Cell Loss Our liver, kidneys and other organs keep a fair number of cells in reserve; still, over time, cell loss may impair their functioning. De Grey’s fix: Engineer embryonic stem cells to create healthy new versions of every type of body cell. Introduce the stem cells into the body to rejuvenate diseased or flagging tissues. The mechanism to deliver the various cell types to all the right places has yet to be developed.
