By studying tissues from deceased people, a team found that women have more rhythmical gene expression and that this molecular rhythmicity decreases with age.
This year’s crop of winning products features many with a clinical focus and others that represent significant advances in sequencing, single-cell analysis, and more.
The tiny strings of RNA promote translation of a protein implicated in cancer, a hint they could regulate gene expression in more ways than previously thought.
The ability to activate different sets of genes has likely helped the chytrid fungus Batrachochytrium dendrobatidis spread widely in amphibians, resulting in global population declines.
A single amino acid substitution in a protein causes increased neuron production in the frontal lobes of humans compared to Neanderthals—a tiny difference that could have given our species a cognitive edge, researchers say.
A study finds that expression levels of certain genes that track with brain activity—particularly those involved in brain development—vary between people with autism and their non-autistic peers.
In two related studies, researchers describe huge chromosomal rearrangements and about 500 novel gene clusters in the octopus, squid, and cuttlefish genomes, which they say could help explain how they evolved their extraordinary brains.
