Life-Space Mobility: Normative Values from a National Cohort of U.S. Older Adults
CONCLUSIONS: We report US national norms for LSA among community-dwelling Black and White older adults. These norms can serve as a reference tool for determining if clinical and research samples have greater or lesser life-space mobility than typical older adults in the US for their age and sex.PMID:37480583 | DOI:10.1093/gerona/glad176

Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage.
Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one.
More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

The final puff: Can New Zealand quit smoking for good?
Smoking kills. Ayesha Verrall has seen it up close. As a young resident physician in New Zealand’s public hospitals in the 2000s, Verrall watched smokers come into the emergency ward every night, struggling to breathe with their damaged lungs. Later, as an infectious disease specialist, she saw how smoking exacerbated illness in individuals diagnosed with tuberculosis and HIV/AIDS. She would tell them: “The best thing you can do to promote your health, other than take the pills, is to quit smoking.”
Verrall is still urging citizens to give up cigarettes—no longer just one by one, but by the thousands. As New...

Artificial Intelligence Is Here To Calm Your Road Rage
I am behind the wheel of a Nissan Leaf, circling a parking lot, trying not to let the day’s nagging worries and checklists distract me to the point of imperiling pedestrians. Like all drivers, I am unwittingly communicating my stress to this vehicle in countless subtle ways: the strength of my grip on the steering wheel, the slight expansion of my back against the seat as I breathe, the things I mutter to myself as I pilot around cars and distracted pedestrians checking their phones in the parking lot.
“Hello, Corinne,” a calm voice says from the audio system. “What’s stressing you out right n...

How to Keep Alzheimer ’s From Bringing About the Zombie Apocalypse
I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer.
My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true.
Seven years ...
