Spacewalking astronauts ventured out Sunday to install support frames for new, high-efficiency solar panels arriving at the International Space Station later this year.
The International Asteroid Discovery Project was conducted by STEM and Space, an organisation working towards the learning of astronomy and space science in India, along with the International Astronomical Search Collaboration (IASC) as part of a NASA citizen science project.
The coronaviruses that cause SARS and Covid-19 have spike proteins that move into 'active' and 'inactive' positions, and the study indicates how those molecular movements may make the Covid-19 virus more infectious compared to the SARS virus, according to researchers, including one of Indian-origin named Vivek Govind Kumar.
National Science Day is celebrated in India every year on February 28. The celebration includes public speeches, radio, TV, science movies, science exhibitions based on themes and concepts, debates, quiz competitions, lectures, science model exhibitions and many more activities.
The findings, published in the journal Blood Advances, indicated that five proteins (resistin, lipocalin-2, HGF, IL-8, and G-CSF) that are associated with neutrophils, a type of white blood cell, were elevated in the Covid-19 patients who later became critically ill.
The launch of GISAT-1 onboard GSLV-F10 rocket was originally planned for March five last year, but was postponed a day before the blast-off due to technical reasons.
The Indian Space Research Organisation (ISRO) is getting ready to launch a new-generation compact rocket on its maiden orbital test flight, the space agency said.
China says its Tianwen-1 spacecraft has entered a temporary parking orbit around Mars in anticipation of landing a rover on the red planet in the coming months.
Only about six people knew about the encoded message before Thursday’s landing, according to Clark. They waited until the parachute images came back before putting out a teaser during a televised news conference Monday.
Hayley Arceneaux, a 29-year-old physician assistant at St. Jude Children's Research Hospital in the US will be the second crew member of Inspiration4, the world's first all-civilian mission to space, SpaceX has announced.
The Perseverance rover landed last Thursday near an ancient river delta in Jezero Crater to search for signs of ancient microscopic life.
There are more than 7,000 coronavirus mutations in India of which some could pose a serious risk, a senior scientist said on Monday. Rakesh Mishra, Director of the Council for Scientific and Industrial Research – Centre for Cellular and Molecular Biology, said among the variants, N440K is spreading a lot more in the southern states.
Billionaire Elon Musk has become a co-author of a study on Covid-19 where he joined researchers to track coronavirus infection in 4,000 SpaceX workers who came forward as volunteers. The findings suggest that only a certain threshold of antibodies may provide people lasting protection against the virus.
Some microbes found on Earth may temporarily survive on the surface of Mars, according to a study that could be vital for the success of future missions to the Red Planet.
Researchers have estimated that a total of 20.5 million years of life have been lost due to Covid-19 worldwide with an average of 16 years per individual death.
