What's up in
Cellular Life, Death and Everything in Between
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
Ancient DNA Yields Snapshots of Vanished Ecosystems
Surviving fragments of genetic material preserved in sediments allow scientists to see the full diversity of past life — even microbes.
Scientists Discover Nearly 200,000 Kinds of Ocean Viruses
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.
Heat-Loving Microbes, Once Dormant, Thrive Over Decades-Old Fire
In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.
Researchers Rethink the Ancestry of Complex Cells
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.
Doudna’s Confidence in CRISPR’s Research Potential Burns Bright
Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.
Artificial Intelligence Finds Ancient ‘Ghosts’ in Modern DNA
With the help of deep learning techniques, paleoanthropologists find evidence of long-lost branches on the human family tree.
Fragile DNA Enables New Adaptations to Evolve Quickly
If highly repetitive gene-regulating sequences in DNA are easily lost, that may explain why some adaptations evolve quickly and repeatedly.
Gene Drives Work in Mice (if They’re Female)
Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
