COVID-19, a disease caused by the novel coronavirus SARS-CoV-2, has been drastically affecting the daily lives of millions of people. COVID-19 is described as a multiorgan disease that affects not only the respiratory tract of infected individuals, but it has considerable effects on the musculoskeletal system, causing excessive fatigue, myalgia, arthralgia, muscle weakness and skeletal muscle damage. These symptoms can persist for months, decreasing the quality of life of numerous individuals. Curiously, most studies in the scientific literature focus on patients who were hospitalized due to SARS-CoV-2 infection and little is known about the mechanism of action of COVID-19 on skeletal muscles, especially of individuals who had the mild to moderate forms of the disease (non-hospitalized patients). In this review, we focus on the current knowledge about the musculoskeletal system in COVID-19, highlighting the lack of researches investigating the mild to moderate cases of infection and po

Under ideal conditions, common swifts can cover more than 500 miles per day for more than a week, report scientists. Seems like an unimaginable feat for such a tiny bird, but swifts have adopted a clever strategy that makes these epic migrations possible.

As a migrating bird, common swifts (
Apus apus) are aptly named. These highly mobile creatures spend more than 80% of their lives in the air when not in breeding mode, and a good portion of this time is spent migrating from northern Scandinavia to their wintering destinations in western and central Africa.
For these long-distance migrations, scientists had previously estimated average speeds of 310 miles per day (500 km/day), but new research published in iScience has updated this figure to 354 miles (570 km/day). More impressively not that this isn’t impressive enough the new study shows that swifts can travel farther and faster than previously thought. At their fastest, swifts can cove
