Persistent fatigue in patients with long COVID has a biological cause, namely mitochondria in muscle cells that produce less energy than in healthy individuals, a study has found. Mitochondria are membrane-bound cell organelles that generate most of the chemical energy needed to power the cell’s biochemical reactions. ”We’re seeing clear changes in the muscles in these patients,” said Michele van Vugt, a professor at Amsterdam UMC in The Netherlands. People with long COVID can have a wide range of symptoms that can last weeks, months, or even years after infection. A total of 25 long COVID patients and 21 healthy

New Delhi, Jan 5 (PTI): An artificial intelligence (AI) model can predict which variants of the Covid-causing SARS-CoV-2 virus will likely bring about fresh waves of the infection, a new research has found.

It will likely make Ukrainian domestic politics more fractious but it could also buy Zelensky time to reconsider his own endgame and how to get there.
