Scientists have revealed how a highly infectious variant of SARS-CoV-2 virus binds to host but succumbs to antibodies later, a discovery that could help in the development of more potent Covid vaccines.
The reason for the enhanced filtration isn't so much adding layers of cloth but eliminating any gaps or poor-fitting areas of a mask, according to the study published in JAMA Internal Medicine.
NASA has picked Elon Musk's SpaceX to develop the first commercial lander and take the next two US astronauts to the moon, the US space agency said on Friday. The contract is worth $2.9 billion and is part of NASA's Artemis programme, which aims to return astronauts to the moon by 2024 as a stepping stone to the first human mission to Mars, DPA news agency reported.

Using data collected by The New York Times to gauge the model's effectiveness, the researchers analysed the cumulative cases per capita in all 50 states in the US between July 14, 2020, through December 10.
The study, published in the journal mSystems, did not evaluate whether the dust can transmit the virus to humans. But, it offers another option for monitoring Covid-19 outbreaks in specific buildings, including nursing homes, offices or schools.

Tesla CEO and SpaceX CEO Elon Musk, who is obsessed with colonizing the red planet, changed his Twitter bio for the second time within a month to add 'Imperator of Mars' with a winking emoji.
NASA has decided to postpone the Ingenuity Mars Helicopter's first experimental flight to April 14 after a test completed earlier than planned.
The National Aeronautics and Space Administration (NASA) will land the first person of colour on the moon as part of an international spaceflight program called Artemis, according to the US space agency.
NASA's Ingenuity Mars Helicopter is two days away from making humanity's first attempt at powered, controlled flight of an aircraft on another planet.
Mars had drier and wetter eras before drying up completely about three billion years ago, says a new study which suggests that the Red Planet did not dry up all at once.
Launched 20 years ago on April 7, the orbiter, which takes its name from Arthur C. Clarke's classic sci-fi novel "2001: A Space Odyssey", was sent to map the composition of the Martian surface, providing a window to the past so scientists could piece together how the planet evolved.
The rare Wolf-Rayet stars are highly luminous objects a thousand times that of the Sun and have intrigued astronomers for long, the Union Ministry of Science and Technology said in a statement on Tuesday.
The findings, published in the journal JAMA Network Open, showed that the blood types A, B, AB and O were not associated with disease susceptibility or severity.

The Oxford–AstraZeneca Covid-19 vaccine, a version of which is also being used in India, is made from an adenovirus isolated from chimpanzee poop, which has been genetically changed so that it is impossible for it to grow in humans.
