Discovery of key decision-point at which cells with broken DNA repair themselves or die

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Treating shoulder separations

While low-level shoulder separations can commonly be treated nonsurgically and high-level injuries often require surgery, a literature review published in the April 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS) finds that many surgeons still disagree on the best course of treatment for those injuries that fall in between.
