A new analysis of data from researchers at King's College London using information from the COVID Symptom Study app and patients admitted to St Thomas' Hospital in London, has shown that delirium - a state of acute confusion associated with a higher risk of serious illness and death - is a key symptom of COVID-19 in frail, older people.

EPFL scientists have measured the molecular footprint that aging leaves on various mouse and human tissues. Using the data, they have identified likely regulators of this central process.
A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps.
Our ability to regulate body temperature and keep our bodies from becoming dehydrated declines as we get older. New research published today in The Journal of Physiology improves our understanding of the relation between temperature regulation and dehydration.
It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases. Now scientists have some of the first evidence that at a younger age at least, senescent cells show up quickly after a major injury and are protective.
New findings suggest that late-onset Alzheimer's Disease is driven by epigenetic changes -- how and when certain genes are turned on and off -- in the brain. Results were published today in Nature Genetics.
An international research team has shown in mice that Rictor, a protein that helps to regulate the growth, energy, and oxygen consumption of cells, plays a key role in the cellular metabolism and longevity of hair follicle stem cells / publication in 'Cell Metabolism'
EPFL scientists have developed a digital pathology tool for quantifying bone marrow compartments in standard histological sections. Named 'MarrowQuant', the software makes it possible to examine bone marrow biopsies as well as to re-examine historical collections of bone-marrow samples and even old clinical trials.
New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like amyloid plaques in the brains of people with clinically-verified obstructive sleep apnea, a condition that affects more than 936 million people worldwide.
