Long-duration space flight equal to decade of bone loss in astronauts, study says

Long-duration space flight equal to decade of bone loss in astronauts, study says

Science
July 1 (UPI) -- Scientists have long known that astronauts lose bone density while in space, but a study published this week found they only partially recover this loss one year after returning to Earth. The researchers said the findings suggest long-duration spaceflight is equal to decades of bone loss in weight-bearing bones on Earth. The extent of the impact, though, varies depending upon the subject. Bone loss happens because bones don't have to carry your weight in microgravity, meaning astronauts use them less, leading to weakening. "Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone," said Leigh Gabel, assistant professor in kinesiology at the University of Calgary and lead author of the study. The researchers scanned ...

‘Tired to the bone’: Hospitals overwhelmed with virus cases

Health
Overwhelmed hospitals are converting chapels, cafeterias, waiting rooms, hallways, even a parking garage into patient treatment areas. Staff members are desperately calling around to other medical centers in search of open beds. Fatigue and frustration are setting in among front-line workers.Conditions inside the nation’s hospitals are deteriorating by the day as the coronavirus rages across the U.S. at an unrelenting pace and the death toll closes in on a quarter-million.“We are depressed, disheartened and tired to the bone,” said Alison Johnson, director of critical care at Johnson City Medical Center in Tennessee, adding that she drives to and from work some days in tears.The number of people in the hospital with COVID-19 in the U.S. has doubled in the past month and set new records eve...
Ambient air pollution linked to bone mass loss in adults

Ambient air pollution linked to bone mass loss in adults

Health
Jan. 3 (UPI) -- Air pollution has obvious effects on health, and it has been linked with everything from increased risk for lung cancer to stroke, among other serious complications. Now, however, a study published Friday by JAMA Network Open has found pollution in the air may have a less obvious, but no less serious, impact on health bone density and strength. The results showed that exposure to ambient air pollution, particularly to fine particles, was associated with lower levels of bone mass, the authors said. "This study contributes to the limited and inconclusive literature on air pollution and bone health," co-author Otavio T. Ranzani, researcher at the Barcelona Institute for Global Health, said in a statement. The findings demonstrated that "inhalation of polluting particles cou...

Humans stored bone marrow for delayed consumption 400,000 years ago

Humans stored bone marrow for delayed consumption 400,000 years ago

Science
Oct. 11 (UPI) -- Paleolithic humans stored animal bones for as long as two months before eating the marrow. The discovery -- published this week in the journal Scientific Advances -- suggests early humans were practicing food storage and delayed consumption as early as 400,000 years ago. The evidence was recovered in Qesem Cave, a Lower Paleolithic archeological site located outside of Tel Aviv, Israel. "Bone marrow constitutes a significant source of nutrition and as such was long featured in the prehistoric diet," Ran Barkai, a professor of archaeology at Tel Aviv University, said in a news release. "Until now, evidence has pointed to immediate consumption of marrow following the procurement and removal of soft tissues. In our paper, we present evidence of storage and delayed consumpti...
