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.
Smarter Parts Make Collective Systems Too Stubborn
As researchers delve deeper into the behavior of decentralized collective systems, they’re beginning to question some of their initial assumptions.
New Squid Genome Shines Light on Symbiotic Evolution
Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
How the Brain Creates a Timeline of the Past
The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.
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.
Why Evolution Reversed These Insects’ Sex Organs
Among these cave insects, the females evolved to have penises — twice. The reasons challenge common assumptions about sex.
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.
How Nearby Stellar Explosions Could Have Killed Off Large Animals
Subatomic particles called muons are thought to have streamed through the atmosphere and irradiated megafauna like the monster shark megalodon.
