Watch How COVID-19 Virus Cause Cell Death in Bat Brain CellsSophie-Marie Aicher and Delphine Planas of the Department of Virology of the Pasteur Institute in Paris, France, captured footage of the COVID-19 virus infection causing cell fusion and cell death in the brains of bats (Myotis myotis).In the video clip, the SARS-CoV-2 virus is shown to infect bat brain cells engineered to express human ACE2 enzyme on its cell membrane, which is the entry point of the coronavirus into the cell. The COVID-19 virus infection triggered syncytia, or cell fusion, as part of the virus' evasion of the immune system response, and led to cell death (the red spots) in just 48 hours.This video won Honorable Mention in the 2021 Nikon Small World In Motion competition.Related:We Don't Talk About Covid, No no noView the full clip below.#COVID19 #coronavirus #braincell #syncytia #cellfusion #celldeath #Nikon #NikonSmallWorldinMotion #InstitutPasteur #photomicrography #microscopySee also: Video of Microorganisms Found in the Gut of a Termite Won the Nikon Small World in Motion 2021 Competition

Video of Microorganisms Found in the Gut of a Termite Won the Nikon Small World in Motion 2021 CompetitionThe 11th annual Nikon Small World In Motion competition winners have been announced. The first place goes to Fabian J. Weston for this amazing video of live microorganisms that live in the gut of a termite.These termite gut microorganisms play an essential role of digesting plant-based cellulose (namely, wood). And they're actually quite difficult to capture on film. It turns out that they are sensitive to light and oxygen levels, and the slightest change in environment can cause both the termite and its guts microorganisms to die."I tried a lot of methods, even preparing my own saline solution. They're very sensitive to oxygen, so I had to remove as much gas from the solution as possible. It was very tricky, and I had to work fast. The video you’re seeing is the result of months of trial and error, a lot of research and perseverance," said Weston in the Nikon Small World in Motion website.#Nikon #NikonSmallWorldinMotion #microscopy #photomicrographyTake a look at the winning videos of the Nikon Small World in Motion 2021:
