New research on mitochondrial function can play significant part in serious disease
Disorders of the cells' energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on mitochondrial function to find future treatments. A new study involving researchers at Karolinska Institutet shows how an important molecule inside the mitochondria affects their function in mice and fruit flies. The study, which is published in Science Advances, adds valuable knowledge on formerly relatively unexplored protein modifications. (2021-02-19)

With a little help from their friends, older birds breed successfully
The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers. (2021-01-19)

A CNIO study links severe COVID-19 disease to short telomeres
The data show that telomeres are shorter in patients suffering more severe COVID-19 pathologies. The researchers propose that one of the consequences of the viral infection is shortening of the telomeres, which, in turn, hampers the regeneration of lung tissue and causes prolonged sequelae in some patients. The study, published in the journal 'Aging', suggests the usefulness of a possible therapy for patients with post-COVID pulmonary injury based on activation of the enzyme telomerase. (2021-01-11)

Teaching computers the meaning of sensor names in smart home
The UPV/EHU's IXA group has use natural language processing techniques to overcome one of the major difficulties associated with smart homes, namely that the systems developed to infer activities in one environment do not work when they are applied to a different one, because both the sensors and the activities are different. The group has come up with the innovative idea of using words to represent the activation of both sensors and human activity. (2020-11-30)

Getting a grip on better health
Men with muscles like a young Arnold Schwarzenegger look powerful but a handshake will give away whether they're a healthy specimen - or at risk of a chronic disease or premature ageing, experts say. Medical researchers in South Australia assessed more than 600 men aged over 40 to 88 years in the Men, Androgen, Inflammation, Lifestyle, Environment, and Stress (MAILES) study to measure the link between sleep apnea and muscle mass with grip strength.
