As we age, our appearance changes, our hair turns gray and wrinkles appear. And we become more susceptible to disease. One reason for this is that our telomeres shorten. These are protective caps at ...

This color-coded graphic shows different populations of cells in the mouse brain, each one targeted by one of the genetic tools developed by scientists at the Allen Institute and other institutions.

CHARM – a novel molecular tool – can turn off disease-causing genes, such as the prion protein gene. Researchers at the Broad Institute of MIT and Harvard have collaborated with the Whitehead ...

Convergent evolution—where distinct species independently evolve similar traits or functions, such as the wings of birds and bats—has long fascinated biologists. Now, a research team led by Prof. Zou ...

The Southern blot, which detects specific DNA sequences, was one of the first molecular diagnostic methods to be widely adopted. 2 This type of probe-based assay uses a single-stranded oligonucleotide ...
