As our cells age, they eventually mature and die. As they die, they alert nearby cells to grow and multiply to replace them. Using a special imaging process that combines video and microscopy, scientists have observed the cellular communication between dying and neighboring cells for the first time, and think they may be able to use their new-found information against cancer cells, whose damaged genomes let them escape the normal dying process.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
