Researchers devise new molecular imaging strategy to observe the sperm selection process

A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the way.

Immune mechanism in COVID-19 patients triggers cytokine storm

Researchers at the University of São Paulo (USP) in Brazil have demonstrated for the first time that in COVID-19 patients an immune mechanism known as the inflammasome participates in activation of the inflammatory process that can damage several organs and even lead to death.

Telomere shortening helps prevent cancer in humans

As time goes by, the tips of your chromosomes--called telomeres--become shorter. This process has long been viewed as an unwanted side-effect of aging, but a recent study shows it is in fact good for you.

KU Leuven vaccine candidate works against yellow fever and SARS-CoV-2 infection

Virologists at the Rega Institute at KU Leuven (Belgium) have developed a vaccine candidate against Covid-19 based on the yellow fever vaccine, which as a result also works against yellow fever. Results published today in Nature show that the vaccine protects hamsters from infection with the SARS-CoV-2 coronavirus after a single dose.

Researchers report AI solution that could revolutionize medical research

Inside every cell, thousands of different proteins from the machinery that keeps all living things - from humans and plants to microscopic bacteria - alive and well. Almost all diseases, including cancer, dementia, and even infectious diseases such as COVID-19, are related to the way these proteins function.
