Jaw muscle size linked to sarcopenia risk in older adults

As populations age, the prevalence of sarcopenia-;a progressive loss of muscle mass and function-;has become an increasingly urgent public health concern. Sarcopenia increases the risk of falls and frailty, reduces the quality of life for older adults, and heightens the likelihood of requiring long-term care. Preventing sarcopenia is, therefore, crucial for alleviating this healthcare burden.

Decoding the genetic roots of stroke and heart attack

In a new study published in the European Heart Journal, researchers at Karolinska Institutet show that genetic traits influence the cellular composition of atherosclerotic plaques, which over time will affect the risk of such lesions to cause a stroke or heart attack. The new knowledge can be used to improve the risk assessment and treatment of patients with atherosclerosis in the future.

Study reveals how time shifts affect metabolism and sleep

Have you ever felt sluggish and out of sorts after a long-haul flight or a late-night shift? A new study from the University of Surrey and the University of Aberdeen has found that disruptions to our body clock, such as those experienced during jetlag, impact our metabolism - but to a lesser extent than sleepiness and the primary clock in the brain.

Researchers uncover hidden roles of accessory genes in SARS-CoV-2

Viruses are lean, mean, infection machines. Their genomes are tiny, usually limited to a handful of absolutely essential genes, and they shed extra genomic deadweight extremely fast.

New approach to stabilize RSV protein could lead to better vaccines

In most people, the lung-infecting pathogens known as respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) trigger mild cold-like symptoms. But in infants and seniors, these viruses can cause severe pneumonia and even death.
