New antiviral compound blocks Covid virus from entering cells: Study

The compound, described in the journal Proceedings of the National Academy of Sciences, targets a key human protein called transmembrane serine protease 2 (TMPRSS2) that coronaviruses harness to enter and infect human cells.
Scientists have developed a chemical compound that they say could prevent infection from SARS-CoV-2 virus or reduce the severity of COVID-19 if given early in the course of an infection.
The compound, called MM3122, interferes with a key feature of many viruses that allows them to invade human cells, according to the researchers at Washington University School of Medicine in the US.

In a study published in the journal Mammalian Biology on December 23, 2024, researchers compared the calls of Asian elephants based on their age, sex, and behaviour. They found the duration of trumpets remained fairly consistent across all age classes for both male and female Asian elephants but roars and roar-rumbles got longer with age.

The STS-63 mission, more popularly dubbed as the near-Mir mission, was a successful mission that spanned from February 3-11, 1995. A mission that served as a dress rehearsal for later missions that would rendezvous and dock with Mir, STS-63 reeled off a number of firsts. A.S.Ganesh tries and lists them out for you…
