Genetic engineering pioneer Kevin Esvelt’s work highlights biotechnology’s immense potential for good—but also for catastrophe.

With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Scientists around the world investigate how bat immune systems cope with viral attacks and how this information could be used to keep humans safe.

Daniel W. Nebert (University of Cincinnati Medical Center): "This review is the third in a series of comprehensive, up- to-date compilations of data about members of the large cytochrome P450 gene superfamily. It serves to organize a large--and growing--body of sequencing and mapping data on 154 P450 genes

The feeling quickly spreads, paralyzing its prey (typically insects) for hours -

Chicz,department of molecular and cellular biology, Harvard University One of the most important findings in this article, according to its authors, was the observation of pr

p53 is possibly the most important protein for maintaining cellular function. Losing it is synonymous with cancer.

We have barely scratched the surface of itch science and what it indicates about our health.

The scientific community bid farewell to researchers who furthered the fields of molecular biology, virology, sleep science, and immunology, among others.
