It may surprise many to learn that, even if joint replacement patients live alone, the overwhelming majority recover equally well and may experience fewer complications if they go home directly from the hospital and get outpatient rehabilitation instead of spending days or weeks in a costly rehab facility.
Based on the findings of recent well-designed studies, Dr. Javad Parvizi, chairman of research in orthopedics at Thomas Jefferson University in Philadelphia, maintains that “we need to re-examine who, if anyone, should go to a rehab facility after joint replacement.”

Very simply, being around other people seems to increase our propensity to believe in fake news….
Groups trigger a certain attitude in us when it comes to evaluating information….
You somehow feel like you’re part of a crowd and you don’t need to fact check because somebody else will. And maybe down the road, they’re going to tell you, hey, you know the thing you were exposed to or that we all read a few days ago? That actually turns out to be false….
Volunteers did 30 to 50 percent less fact checking when they heard information presented to them in a social media context compared to when they were alone.

SHIPS spewing soot into the pristine ocean air are causing extra lightning strikes along busy maritime routes. It is a bizarre example of how human activities can change the weather.
When Joel Thornton at the University of Washington in Seattle and his colleagues looked at records of lightning strikes between 2005 and 2016 from the World Wide Lightning Location Network, they noticed there were significantly more strikes in certain regions of the east Indian Ocean and the South China Sea, compared with the surrounding areas. Unusually, they occurred along two straight lines in the open ocean, which coincided with two of the busiest shipping lanes in the world. Along these paths there were twice as many lightning strikes as in nearby areas.
Being immobile like that for many hours each day does more than raise the risk of a host of diseases. DiPietro and her colleagues have good evidence that, as the years wear on, it actually reduces the ability of older people to get around on foot at all.
In a study of sitting and walking ability that surveyed people ages 50 to 71 across 8 to 10 years, those who tended to sit the most and move the least had more than three times the risk of difficulty walking by the end of the study, when compared to their more active counterparts.

Kids love the gardens, she says. It gives them a way to briefly forget their worries.
“Having access to a bit of nature, having a tree to read under, or, having a safe space like one of our gardens, definitely makes a huge difference on their stress levels,” says Lemos-Otero. “The feedback that we’ve gotten from a lot of young people is that it makes them feel a little lighter.”
Now a group of researchers from Philadelphia have published research that supports her experience. The study, published Friday in JAMA Network Open, found that having access to even small green spaces can reduce symptoms of depression for people who live near them, especially in low-income neighborhoods.

A wave of ultra-long flights that will get you halfway around the world in one hop is pushing airlines to deal with the one extra you can’t escape: Relentless insomnia, debilitating fatigue and tormented bowels, better known as jet lag.
Qantas Airways Ltd., which will start the first non-stop service between Australia and Europe in March, is working with scientists in Sydney to discover ways to limit body-clock breakdown on the 17-hour flight. They’ve tried to make the color and intensity of the jet’s interior lights mimic dawn and dusk. Cabin temperatures and specially made meals will aim to put passengers to sleep or keep them awake—depending on the time at the destination.
Key to the problem is circadian disruption—messing with the internal body clock that regulates everything from brainwave activity to hormone production and cell regeneration.
The main cue for resetting that clock is light, said Steve Simpson, academic director of the Charles Perkins Centre, which is carrying out the research with Sydney-based Qantas. But there’s a baked-in biological catch: the clock can only reset by about 90 minutes a day, even in the right conditions. An ill-timed dose of sunshine or a badly chosen snack at the wrong hour can mean days of suffering, he said.
