World’s Simplest Animal Reveals Hidden Diversity
The first animal genus defined purely by genetic characters represents a new era for the sorting and naming of animals.
DNA Analysis Reveals a Genus of Plants Hiding in Plain Sight
Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.
To Heal Some Wounds, Adult Cells Turn More Fetal
Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.
You Are Getting Sleepy — Tagged Proteins May Point to Why
The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.
‘Functional Fingerprint’ May Identify Brains Over a Lifetime
A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.
How Insulin Helped Create Ant Societies
Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.
A Math Theory for Why People Hallucinate
Psychedelic drugs can trigger characteristic hallucinations, which have long been thought to hold clues about the brain’s circuitry. After nearly a century of study, a possible explanation is crystallizing.
Swarming Bacteria Create an ‘Impossible’ Superfluid
Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.
To Remember, the Brain Must Actively Forget
Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.
