A team of evolutionary biologists and biomedical researchers lay out evolutionary and biomedical evidence showing that humans, who evolved to live many decades after they stopped reproducing, also evolved to be relatively active in their later years. The researchers say that physical activity later in life shifts energy away from processes that can compromise health and toward mechanisms in the body that extend it. They hypothesize that humans evolved to remain physically active as they age -- and in doing so to allocate energy to physiological processes that slow the body's gradual deterioration over the years. This guards against chronic illnesses such as cardiovascular disease, type 2 diabetes, and even some cancers.

New research shows how genetic variations linked to severe cases of COVID-19 affect our immune cells. The study is one of the first in-depth look at the connections between COVID-19 severity and gene expression in many types of immune cells. This work could guide the development of new COVID-19 therapies to boost immune cell function.

Obesity, diabetes and gastrointestinal cancer are frequently linked to an unhealthy diet. However, the molecular mechanisms responsible for this are not fully understood. Researchers have gained some new insights that help to better understand this connection. These findings provide an important basis for the development of non-invasive therapies.
