A lot of people seem willing to spend hundreds to find out whether they’re aging faster or slower than their chronological age would suggest. Unfortunately, they’re just going to have to wait and see. A head-to-head comparison of 11 different measures of aging, including blood and chromosome tests like those being sold commercially, has found that they don’t agree with one another on how fast a given person is growing older.
The bacterium Pseudomonas aeruginosa is the leading cause of hospital-acquired infections. The pathogen is resistant to many antibiotics so treating those infections, particularly in patients with compromised immune systems, is difficult. A new study has identified certain chemical receptors in cells that could deceive the bacteria and improve patient response to drugs.
Can a close look at the universe give us solutions to problems too difficult for a computer — even if we built a computer larger than a planet? Physicist Stephen Jordan reflects on this question in a new NIST video, along with a scientific paper that considers one particular tough problem the universe might answer.
The first genetic mutation that appears to protect against multiple aspects of biological aging in humans has been discovered in an extended family of Old Order Amish living in the vicinity of Berne, Indiana, report scientists. An experimental “longevity” drug that recreates the effect of the mutation is now being tested in human trials to see if it provides protection against some aging-related illnesses.
