While we all aspire for a long lifespan, what is most coveted is a long period of vigor and health, or "healthspan," that precedes the inevitable decline of advancing age. Researchers at UC Santa Barbara have discovered that ...

The recent approval of a CRISPR-Cas9 therapy for sickle cell disease demonstrates that gene editing tools can do a superb job of knocking out genes to cure hereditary disease. But it's still not possible to insert whole genes ...

Researchers at universities in New York and Ningbo, China, say they have created tiny robots built from DNA that can reproduce themselves.
This week, we reported on LIGO upgrades, parasitic fungi and a new analysis of Curiosity rover data. Also, did you know that viruses also attack bacteria? But at that scale, it's a lot less like catching a cold and a lot ...
All animals have evolved thanks to the fact that certain viruses infected primitive organisms hundreds of millions of years ago. Viral genetic material was integrated into the genome of the first multi-cellular beings and ...
