Extra thymus discovered in mice

The thymus is an organ in mice which helps produce the infection-fighting T cells of the immune system. The main one is situated in the chest above the heart, but scientists have only now discovered a second, smaller one hidden in the necks of mice.

You'd think they'd have noticed this after a few decades of taking the poor buggers apart, but there goes mother nature again, having a laugh at our expense. For the strong-stomached among you, you'll find a dissection picture here that points out the chest-cavity thymus. Be quite handy if we could graft some extra thymus organs into our necks to stave off infection. Not that it'll help when you get eaten by a bobcat...
