This scientist paved the way for the Pfizer COVID-19 vaccine

PHILADELPHIA — When Drew Weissman first started injecting mice with genetic molecules called messenger RNA, it did not go well.Many of the animals became overwhelmed with harmful inflammation, and some died.But Weissman solved that problem with a bit of clever biochemistry 15 years ago, working with then-colleague Katalin Karikó at the University of Pennsylvania. Now their work forms the backbone of two vaccines for COVID-19, including the one for which dramatic early results were announced this week.The vaccine made by Pfizer Inc. and the German firm BioNTech SE, where Karikó now works, appea...

Study helps predict which COVID-19 patients develop dangerous 'cytokine storm'

Some of those who get really sick with COVID-19 develop dangerous, systemic inflammation, triggered by an overactive immune response called a cytokine storm. But predicting who will go down that path, and how to prevent it, remains a challenge.A new Temple University study has identified a handful of chemical markers, easily measured with standard hospital blood tests, that may help.The authors started by measuring the levels of 62 such markers in hundreds of hospitalized COVID-19 patients, including proteins and other substances related to metabolism, the immune system, and other bodily funct...

US-French duo win Nobel Chemistry Prize for gene editing tool

Stockholm (AFP) - Emmanuelle Charpentier of France and Jennifer Doudna of the US on Wednesday won the Nobel Chemistry Prize for the gene-editing technique known as the CRISPR-Cas9 DNA snipping "scissors", the first time a Nobel science prize has gone to a women-only team.Using the tool, "researchers can change the DNA of animals, plants and microorganisms with extremely high precision," the Nobel jury said."This technology has had a revolutionary impact on the life sciences, is contributing to new cancer therapies and may make the dream of curing inherited diseases come true."The technique has...
