senescence

The research team used a novel method to evaluate senescence -- when a cell can no longer divide.

This protein is involved in cellular senescence—the process by which cells age—and is expressed at higher levels in older people.

Developing a trusted relationship with an arborist can help with that, and with reading our trees’ health — identifying which ones are moving toward senescence, for example, and require a safe, environmentally sensitive transition plan.

But, “When they persist, they cause havoc,” says Jesús Gil, a cellular senescence expert at Imperial College London who wasn’t connected to the new research.

Many breed once, then die shortly after, either from senescence or predation.
