‘Zombified’ cells in blood vessels may play a key role in the development of age-related metabolic diseases such as diabetes, a new study has found. And killing these zombie cells could be a promising approach for future treatments.Cells normally respond to stress by becoming senescent, a state in which cells remain in the body in which they permanently stop dividing. These senescent cells may have several useful functions. For example, some play an important role in wound healing. However, as senescent cells accumulate in the body over time, they are also known to be the cause of age-related diseases.In previous…

But what happened this year at the CDC is unprecedented, former CDC officials say.Three former CDC leaders say the transition to the second Trump administration has created chaos and disorganization at the agency, and that this destabilization ultimately endangers public health. Additionally, the new administration’s appointees have grossly “ignored” the expertise of scientists, he said in a…
