All creatures great and small: Sequencing the blue whale and Etruscan shrew genomes

Size doesn’t matter when it comes to genome sequencing in the animal kingdom, as a team of researchers at the Morgridge Institute for Research recently illustrated when assembling the sequences for two new reference genomes — one from the world’s largest mammal and one from one of the smallest.

New study shows mRNA vaccine harnesses T-cell power to combat COVID-19 in lungs

The study sheds new light on the protective mechanisms mRNA vaccines use to lessen severe disease following breakthrough infections. It also raises important new questions about the role of memory T cells in limiting the spread of the virus, the frequency with which we get vaccinated and the most effective methods for vaccine delivery.
