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.
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.
