Impaired cardiac metabolism linked to increased risk of fatal arrhythmias or sudden cardiac death

Adults with abnormal heart metabolism are up to three times more likely to experience life-threatening arrhythmias (an irregular heart rhythm), and MRI techniques could be used to detect the condition and predict future sudden cardiac death (SCD), according to a small, but rigorous study led by Johns Hopkins Medicine researchers.

Cognitive fatigue due to exercise in low-oxygen conditions can be avoided by maintaining oxygen saturation

When physically demanding activities are performed at high altitude or in other low-oxygen environments, excellent coordination, judgment, and decision-making are important. In some cases, such as when mountaineering, these capabilities may be the difference between life and death.

Scientists discover mechanism behind zoonotic transfer of SARS-CoV-2 virus

The original SARS-CoV-2 viral strain that emerged in early 2020 was able to latch on to sugars known as sialic acids, found on the surface of human cells, an ability that later strains did not retain.
