Ingenuity Mars flew to the Red Planet on February 18, while being attached to the belly of NASA's Perseverance rover. On its fifth flight on Mars, the mini-helicopter took the one-way trip from Wright Brothers Field to a new airfield 423 feet (129 metres) to the south. This was the first time it flew to a new landing site, the US space agency said on Saturday.
The veteran Falcon 9 rocket blasted off before dawn from Space Launch Complex 40 here at Cape Canaveral Space Force Station at 2:42 a.m. EDT (06.42 GMT), marking the company's 14th launch of the year. It was also one for the record books as the flight was this particular booster's 10th launch and landing attempt, the company said in a statement.
People release respiratory fluids during exhalation -- quiet breathing, speaking, singing, exercise, coughing, sneezing in the form of droplets. While large droplets settle out of the air within seconds to minutes, very fine droplets can remain suspended in the air for minutes to hours. These droplets carry viruses and transmit infection, said the agency's latest science brief as part of its public guidelines on Covid-19.
Researchers from the Whitehead Institute for Biomedical Research and Massachusetts Institute of Technology (MIT) in the US, showed that genetic sequences from the RNA virus SARS-CoV-2 can integrate into the genome of the host cell through a process called reverse transcription. These sections of the genome can then be "read" into RNAs, which could potentially be picked up by a PCR test.
"People with heart problems, diabetes, high blood pressure, and other co-morbidities fall into the high-risk category as they get sick from Covid. The virus not only affects the lungs and the brain but your heart as well. There is a steep rise in post-Covid patients with cardiac issues like breathing problems, chest tightness and pain, heart attack, myocarditis, swelling of the heart, heart failure, blood clotting and arrhythmia said Pramod Narkhede, Cardiologist
The "out-of-control" Chinese Long March 5B rocket "re-entered over the Arabian Peninsula at approximately 10:15 p.m. EDT (around 7.45 am India time on Sunday)," according to US Space Command that was tracking the rocket. It was, however, still unknown if the debris impacted land or water. The agency's official Twitter account tweeted: "Everyone else following the #LongMarch5B re-entry can relax. The rocket is down."
The study found a statistically significant improvement in exercise capacity, as measured by scores of distance travelled and ability to keep going without rest using incremental and endurance shuttle-walking tests. "This adapted rehabilitation programme for individuals following Covid-19 has demonstrated promising improvements in clinical outcomes," said researcher Sally Singh from the University of Leicester.
