How to protect nerve cells in a stroke

Many neurons can survive a stroke, but for this you need to prevent them from losing too much potassium. A circulatory disturbance in the brain threatens with a stroke: a little blood comes to neurons, they lack oxygen and nutrients, and as a result, nerve cells die in large numbers. But among them there are […]

Why does the new coronavirus cause severe inflammation?

The SARS-CoV-2 virus raises the level of the hormone, which triggers self-reinforcing inflammation. The new SARS-CoV-2 coronavirus is notorious for causing severe inflammation, which is very harmful to healthy tissues. In connection with coronavirus inflammation, one can often hear the term “cytokine storm” – because during the disease, the level of inflammatory signaling cytokine signal […]

Immunity learns to fight the new coronavirus on old coronaviruses

In the blood of people who have never had COVID-19, there are immune cells that can recognize the new coronavirus. When an infection enters the body, the cells and molecules related to innate immunity are the first to respond to it. They respond to nonspecific signs of bacteria and viruses, for example, fragments of the […]

One in a million: find a strange super-earth towards the center of our galaxy
