Researchers invent new gene-editing tool

Researchers from the University of Illinois Chicago have discovered a new gene-editing technique that allows for the programming of sequential cuts—or edits—over time.

Scientists use DNA origami to monitor CRISPR gene targeting

The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target. Though CRISPR has completely changed the pace of ...

Unusual DNA folding increases the rates of mutations

DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research by a team of Penn State scientists shows that the elevated ...

Researchers advance simple and inexpensive diagnostic blood test

In diagnostic medicine, biopsies, where a sample of tissue is extracted for analysis, is a common tool for the detection of many conditions. But this approach has several drawbacks—it can be painful, doesn't always extract ...

Reindeer lichens are having more sex than expected

In northern Canada, the forest floor is carpeted with reindeer lichens. They look like a moss made of tiny gray branches, but they're stranger than that: they're composite organisms, a fungus and algae living together as ...
