NASA suspends $2.9B SpaceX lunar lander project amid protests
IANS -
Blue Origin had filed a protest with the US Government Accountability Office (GAO) against NASA for awarding $2.9 billion contract to SpaceX for landing astronauts on the Moon by 2024. The US space agency was expected to pick two lunar lander prototypes (including one of Blue Origin's) but funding cut from US Congress led the agency to select SpaceX over Blue Origin.

The experiment, under NASA's Scientific Balloon Programme, will kick off an ambitious schedule of 18 flights in 2021. The first campaign of 2021 -- with six balloon flights -- will lift off from NASA's Columbia Scientific Balloon Facility's field site in Fort Sumner, New Mexico, between April-end and mid-June.

In the study, published in the journal EBioMedicine, the team described two children and a young adult with acute lymphoblastic leukemia who tested positive for SARS-CoV-2 for months. Lymphoblastic leukemia is a type of cancer of the blood and bone marrow that affects white blood cells.

"Our analysis shows that P1 emerged in Manaus around November 2020. It went from not being detectable in our genetic samples to accounting for 87 per cent of the positive samples in just seven weeks. It has since spread to several other states in Brazil as well as many other countries around the world," said Samir Bhatt, a researcher at Copenhagen University's Department of Public Health.

During the 1969 Apollo 11 mission, Collins remained in lunar orbit while fellow crew members Neil Armstrong and Buzz Aldrin descended to the moon's surface in the lunar module. When Armstrong and Aldrin descended to the moon's surface on July 20, Collins was orbiting 65 miles above them and was momentarily almost forgotten as the world's attention focused on his two crewmates below.

SARS-CoV-2, the virus that causes Covid-19, is covered in tiny spike proteins. These proteins bind with receptors on our cells, starting a process that allows the virus to release its genetic material into a healthy cell.

Gene changes may explain symptoms in Covid survivors

During an infection, the spike proteins bind with receptors on cells in our body, starting a process that allows the virus to release its genetic material into the inside of the healthy cell. "We found that exposure to the SARS-CoV-2 spike protein alone was enough to change baseline gene expression in airway cells," said Nicholas Evans, a student at the Texas Tech University Health Sciences Centre in the US.

The uncertainty about their present and future, coupled with government mandates to stay at home, is all exacerbating mental illness. The feeling of being cooped up at home, distant from their loved ones, devoid of social support and fear about new variants is increasing mental illness, according to mental health experts.
