Several cancers can be detected with liquid biopsies. These blood tests often involve capture of cell-free DNA (cfDNA) targets using oligonucleotide probes. The shorter these probes are, the quicker ...

For more than a century, heredity has been framed through the tidy logic of Mendel's pea plants: traits pass from parent to offspring by fixed genetic rules. But a new mouse study suggests that ...

It does mean they may not tell the whole story. In this case, researchers found that DNA methylation, a chemical tag that can turn genes on or off without changing the DNA sequence itself, sometimes ...

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists. By Carl Zimmer Scientists at Columbia University have ...
