An augmented immune response explains the adverse course of COVID-19 in patients with hypertension

This most likely explains the augmented response of the immune system and the more severe disease progression. However, certain hypertension-reducing drugs known as ACE inhibitors can have a beneficial effect. They not only lower blood pressure, but also counteract immune hyperactivation. The scientists have now published their findings in the journal Nature Biotechnology. More than […]

Research explains why crocodiles have changed so little since the age of the dinosaurs

New Hubble data explains missing dark matter

This image shows the sky around the ultra diffuse galaxies NGC 1052-DF4 and NGC 1052-DF2. It was created from images forming part of the Digitized Sky Survey 2. NGC 1052-DF2 is basically invisible in this image.  In 2018 an international team of researchers using the NASA/ESA Hubble Space Telescope and several other observatories uncovered, for the first time, […]

New study explains important cause of fatal influenza — ScienceDaily

It is largely unknown why influenza infections lead to an increased risk of bacterial pneumonia. Researchers at Karolinska Institutet in Sweden have now described important findings leading to so-called superinfections, which claim many lives around the world every year. The study is published in the journal PNAS, Proceedings of the National Academy of Sciences, and […]

What does ‘close contact’ for COVID-19 really mean? Epidemiologist explains.

The Centers for Disease Control and Prevention has new guidance clarifying what exactly “close contact” means when it comes to transmission of SARS-Cov-2, the virus that causes COVID-19. The previous guidance suggested that a close contact occurred when a person was within six feet of an infectious individual for 15 consecutive minutes. Now, the CDC is acknowledging […]

Study explains the process that exacerbates MS — ScienceDaily

People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers at Karolinska Institutet have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study, which is published in Science Immunology, can prove valuable to future treatments. MS is a chronic inflammatory disease […]
