In Brain’s Electrical Ripples, Markers for Memories Appear
Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.
Scientists Debate the Origin of Cell Types in the First Animals
Theories about how animals became multicellular are shifting as researchers find greater complexity in our single-celled ancestors.
How Swarming Insects Act Like Fluids
By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.
Where We See Shapes, AI Sees Textures
To researchers’ surprise, deep learning vision algorithms often fail at classifying images because they mostly take cues from textures, not shapes.
Bacterial Complexity Revises Ideas About ‘Which Came First?’
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
Immune Cells Measure Time to Identify Foreign Proteins
Immunologists confirm an old hunch: T-cells identify what belongs in the body by timing how long they can bind to it.
Brains Speed Up Perception by Guessing What’s Next
Your expectations shape and quicken your perceptions. A new model that explains how that happens also suggests it’s time to update theories about sensory perception and decision making.
New Turmoil Over Predicting the Effects of Genes
Promising efforts at disentangling the effects of genes and the environment on complicated traits may have been confounded by statistical problems.
Goals and Rewards Redraw the Brain’s Map of the World
Two new studies show that the brain’s navigation system changes how it represents physical space to reflect personal experience.
