New York is in the midst of an outbreak of measles, a childhood disease that shouldn’t really exist in the U.S. any longer. On Tuesday, NBC News reported, New York health officials said the state has seen more than 100 cases of the vaccine-preventable disease since last September—a tally not seen in decades.

Measles is a highly infectious disease that can be spread with a simple cough or sneeze. Its flu-like symptoms are usually followed by a distinctive, splotchy red rash that runs down from head to feet.

These risks are more likely in the very young; measles can also cause birth problems in children whose mothers contract it while pregnant.

Now researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered a process that can help to control the disruptions thought to be most dangerous.

A drug to fight ageing may finally be on the horizon after the first trial in humans showed ‘impressive’ results.
For many years scientists have known that an accumulation of senescent cells in the body is linked to ageing symptoms such as frailty and arthritis, as well as diseases such as Alzheimer’s and Parkinson’s.
Senescent cells — also known as zombie cells — are not completely dead so are not cleared out by the body, but are too damaged to repair tissue or carry out normal functions. Unable to repair itself or clear out the waste, the body gradually deteriorates.
