The quake, which had a magnitude of 4.7 and caused vibrations to reverberate through Mars for at least six hours, was recorded by NASA’s InSight lander on May 4 2022. Because its seismic signal was similar to previous quakes known to be caused by meteoroid impacts, the team believed that this event (dubbed ‘S1222a’) might…

The four earthquakes in October near Herat, Afghanistan, should be called as ‘multiplets’ rather than mainshocks or aftershocks | Photo Credit: AP In a short span of about a week, a region about 40 km from Herat, Afghanistan was struck by four shallow focus earthquakes of 6.3 magnitude. The first earthquake of 6.3 magnitude occurred at a…

A recent study published in Nature reveals major changes in the ecology and evolution of highly pathogenic avian H5 influenza viruses, including a shift in global distribution. The findings suggest that the epicentre of these viruses has extended beyond Asia to new regions including parts of Africa and Europe. Highly pathogenic avian H5N1 virus activity has intensified…

Researchers have finally uncovered a multiorgan pathway with important implications for the pathogenesis of Long COVID. Several hypotheses have been proposed to explain the causes of Long COVID. These include the presence of a viral reservoir long after initial infection; chronic inflammation, development of antibodies (as a result of anti-viral responses) that mistakenly target and…

The story so far: In October, biochemist Katalin Karikó became only the 23rd woman in Nobel’s 122-year-long history to have won the prestigious award in science and medicine. Her three-decade-long investigation into mrRNA vaccines ‘almost didn’t happen’: she struggled with funding, her institute demoted her and rejection letters from publications piled on. Dr. Kariko’s historic…

The planet Mars is shown in this NASA Hubble Space Telescope view taken May 12, 2016. | Photo Credit: Reuters On May 4, 2022, NASA’s InSight lander detected the largest quake yet recorded on Mars, one with a 4.7 magnitude – fairly modest by Earth standards but strong for our planetary neighbour. Given Mars lacks…
