[ad_1] Treatments that use the immune system to fight cancer have greatly improved outcomes for some people with cancer. Scientists are learning more about why some people respond so much better than others to these drugs. One major factor is something called tumor mutation burden (TMB) – the number of …

[ad_1] COLUMBUS, Ohio – New research has identified and described a cellular process that, despite what the textbooks say, has remained elusive to scientists until now – precisely as the copy of genetic material that, once initiated, is conveniently deactivated. . The discovery concerns a key process essential to life: …

[ad_1] Newswise – CHAPEL HILL, NC – November 25, 2020 – For space exploration to be successful, we need to understand and address the underlying causes of the health problems seen in astronauts who have spent long periods of time away from Earth. These problems include bone and muscle loss, …

[ad_1] Ribosomes synthesize all proteins in cells. Studies conducted primarily in yeast have revealed much about how ribosomes are assembled, but a Ludwig-Maximilians-Universitaet (LMU) team in Munich now reports that assembling ribosomes in human cells requires factors that have no counterparts in more model organisms. simple. In each cell, hundreds …

[ad_1] Newswise – Until now, it was unclear whether a surviving SARS-CoV-2 or COVID-19 infection led to persistent immunological memory and thus could protect against re-infection. Several studies have shown that SARS-CoV-2 specific antibodies are only detectable for a few months in many COVID-19 survivors and can therefore only provide …
