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 ...

Detecting changes in the brain can be very difficult. Scientists have now developed a kind of molecular flashlight that can illuminate the composition of neural tissue with a non-invasive, ultra-thin ...

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.

The detection of rare variants or mutations in the human genome can take time and cost a lot of money. In recent years, scientists and clinicians have been aiming to make the process cheaper and ...

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 ...

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 ...
