DNA

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

Surviving fragments of genetic material preserved in sediments allow scientists to see the full diversity of past life — even microbes.

New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.

In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.

New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many.

Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.

With the help of deep learning techniques, paleoanthropologists find evidence of long-lost branches on the human family tree.

If highly repetitive gene-regulating sequences in DNA are easily lost, that may explain why some adaptations evolve quickly and repeatedly.

Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
