SARS-CoV-2 mutations do not appear to increase transmissibility
by University College London A colorized scanning electron micrograph of the SARS-CoV-2 virus. Credit: NIAID None of the mutations currently documented in the SARS-CoV-2 virus appear to increase its transmissibility in humans, according to a study led by UCL researchers. The analysis of virus genomes from over 46,000 people with COVID-19 from 99 countries is published...

BIOLOGY OF AGEING/ SEBASTIAN GRÖNKE AND YU-XUAN LU Reduced food intake, known as dietary restriction, leads to a longer lifespan in many animals and can improve health in humans. However, the molecular mechanisms...
New study explains important cause of fatal influenza
Posted Today It is largely unknown why influenza infections lead to an increased risk of bacterial pneumonia. Researchers at Karolinska Institutet 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 can...
DRUG LETS KIDS WITH TYPE 1 DIABETES PRODUCE INSULIN
2020POSTED BY ELLEN GOLDBAUM-BUFFALO “During the period just after diagnosis, called partial remission or the honeymoon period, patients are still able to make some insulin on their own,” says Teresa Quattrin. “That is the period we have targeted with this study of golimumab.” (Credit: Getty Images)SHARE THIS ARTICLE Facebook Twitter Email You are free to share this...
UB researchers uncover new functions in ataxin 3 gene that causes Machado
Reviewed by Emily Henderson, B.Sc.Nov 25 2020 Ataxia is a minority disease with genetic origins, known for its neuromuscular alterations due to the selective loss of neurons in the cerebellum, the organ of our nervous systems which controls movement and balance. UB researchers have identified new functions in the ataxin 3 gene (ATXN3) -which causes Machado-Joseph disease, the...
Team uses copper to image Alzheimer’s aggregates in the brain
