Covid-19 could cause long-lasting damage to heart: Doctors
"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
WATCH | ‘Out of control' Chinese rocket falls over Indian ocean
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."
Exercise linked to improvement in Covid symptoms recovery
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.
Mild Covid very unlikely to cause lasting heart damage: Study
"Disentangling the impact Covid-19 has on the heart has been a challenge. But we're now at the stage of the pandemic where we can really start to get a grip on the longer-term implications Covid-19 has on the health of our heart and blood vessels," said Treibel. For the study, published in the journal JACC: Cardiovascular Imaging, the research team included 149 healthcare workers.
Unique infectious profile' makes Covid so hard to treat: Lancet
According to the a review published in the prestigious journal The Lancet, there is growing evidence that the virus infects both the upper and lower respiratory tracts. The review suggests that it is unlike "low pathogenic" human coronavirus sub-species, which typically settle in the upper respiratory tract and cause cold-like symptoms or "high pathogenic" viruses such as those that cause SARS and ARDS.
First-ever global initiative to map mammal migrations
The detailed maps of the seasonal movements of herds worldwide will help governments, indigenous people and local communities, planners, and wildlife managers to identify current and future threats to migrations, and advance conservation measures to sustain them in the face of an expanding human footprint. The Global Initiative on Ungulate Migration was launched with the publication of a commentary titled "Mapping out a future for ungulate migrations,"
Watch: SpaceX successfully lands Starship prototype in 5th attempt
All four previous high-altitude prototypes exploded upon attempting to land -- either on, shortly before, or moments after the touchdown. Musk has said the SN15 rocket contained "hundreds of design improvements" over past high-altitude prototypes, which were all destroyed during explosive landing attempts. "Starship landing nominal!" Musk tweeted about seven minutes after SN15's touchdown.
ISRO trials Garuda drones for veggies & med delivery in Sriharikota
"In a pilot project, based drones of Garuda Aerospace delivered vegetables and medicines at the ISRO staff quarters and also sanitised the buildings in Sriharikota. We also sanitised the buildings using unmanned vehicles," Agnishwar Jayaprakash, Managing Director of city-based Garuda Aerospace, told IANS.
Decoded: How antibodies neutralise Covid infection
The team from the University of Texas at Austin analysed blood plasma samples from four people who recovered from SARS-CoV-2 infections. They found that most of the antibodies circulating in the blood -- on average, about 84 per cent -- target areas of the viral spike protein outside the receptor-binding domain (RBD) -- the most obvious part of the coronavirus's spike protein.
Applying UV light to common disinfectants can reduce toxicity
The simple application of UVC light -- the type of ultraviolet light that's most effective at killing germs -- on common disinfectants used to protect against a wide range of viruses and bacteria, including all strains of Coronavirus, can make it safer for humans as well as the environment, finds a study.
