Model analyzes how viruses escape the immune system

One reason it's so difficult to produce effective vaccines against some viruses, including influenza and HIV, is that these viruses mutate very rapidly. This allows them to evade the antibodies generated by a particular vaccine, ...

Quick and sensitive identification of multidrug-resistant germs

Researchers from the University of Basel have developed a sensitive testing system that allows the rapid and reliable detection of resistance in bacteria. The system is based on tiny, functionalized cantilevers that bend ...

Flaws emerge in modeling human genetic diseases in animals

My lab, based at the University of Southern California Keck School of Medicine, uses zebrafish to model human birth defects affecting the face. When I tell people this, they are often skeptical that fish biology has any relevance ...

Lab tests show risks of using CRISPR gene editing on embryos

A lab experiment aimed at fixing defective DNA in human embryos shows what can go wrong with this type of gene editing and why leading scientists say it's too unsafe to try. In more than half of the cases, the editing caused ...

Yeast study yields insights into longstanding evolution debate

In the past two decades, researchers have shown that biological traits in both species and individual cells can be shaped by the environment and inherited even without gene mutations, an outcome that contradicts one of the ...
