Bacteria may not hasten death
...The study is part of a broader effort in the Tower lab
to eliminate irrelevant factors in aging and close in on its fundamental causes. We want to determine what limits the life span of the fly, or any other animal, Tower said. Towers team eliminated bacteria as a factor by comparing normal fruit fl...

How a pain in the neck could be bad for your blood pressure
A chance discovery in the lab
