For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth had a much better chance of surviving treatment.
Most people can name at least a few bones of the human body, but not many know about the cytoskeleton within our cells, let alone the “microtubules” that give it its shape. Now, a group of Princeton researchers has resolved a long-standing controversy by identifying exactly how the body creates these micron-sized filaments.
Scientists have recently learned how to use light to control specific groups of neurons to better understand the operation of the brain, a development that has transformed areas of neuroscience.
