Broken DNA Must Find Right Partners Quickly Amid Repairs

Just as square dance partners join hands at a particular point in the music, so broken pieces of DNA in our cells reunite as they are repaired. Precisely and quickly, these DNA pieces identify each other and tether together. A tumor-suppressor gene called ATM choreographs this fast-paced, but reliable, reassembly operation.

Bacteria Fight Back: Biofilms Use Chemical Weapons To Neutralize Or Kill Attacking Amoebae

Biofilms develop on any surface that bacteria can attach themselves to. The dilemma we face is that neither disinfectants and antibiotics, nor phagocytes and our immune system can destroy these biofilms. Scientists have now identified one of the fundamental mechanisms used by the bacteria in biofilms to protect themselves against the attacking phagocytes.
