Evidence supports Covid hearing loss link

Hearing loss and other auditory problems are strongly associated with Covid-19 according to a systematic review of research evidence led by University of Manchester and NIHR Manchester Biomedical Research Centre (BRC) scientists. Professor Kevin Munro and PhD researcher Ibrahim Almufarrij found 56 studies that identified an association between COVID-19 and auditory and vestibular problems. They […]

Cardiorespiratory fitness improves grades at school

By confirming the link between children’s cardiorespiratory fitness and their school results, researchers at the UNIGE underline the importance of physical education classes at school. Recent studies indicate a link between children’s cardiorespiratory fitness and their school performance: the more athletic they are, the better their marks in the main subjects – French and mathematics. […]

Selenium supplementation protects against obesity and may extend lifespan

Supplementation of the nutrient selenium protects against diet-induced obesity and may extend the lifespan of mice by controlling energy-regulating hormones. Adding the nutrient selenium to diets protects against obesity and provides metabolic benefits to mice, according to a study published in eLife . The results could lead to interventions that reproduce many of the anti-aging […]

Covid-19 risk increases with airborne pollen

When airborne pollen levels are higher, increased SARS-CoV-2 infection rates can be observed. These results were determined by a large-scale study conducted by an international team headed by researchers at the Technical University of Munich (TUM) and the Helmholtz Zentrum München. Members of high-risk groups could protect themselves by watching pollen forecasts and wearing dust […]

Antihypertensive properties of green and black tea

A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall. The discovery helps explain the antihypertensive properties of tea and could lead to the design of new blood pressure-lowering medications. Published in Cellular Physiology […]
