His Artificial Intelligence Sees Inside Living Cells
The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.
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.
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.
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.
What’s in a Name? Taxonomy Problems Vex Biologists
Researchers struggle to incorporate ongoing evolutionary discoveries into an animal classification scheme older than Darwin.
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.
Do Brains Operate at a Tipping Point? New Clues and Complications
New experimental results simultaneously advance and challenge the theory that the brain’s network of neurons balances on the knife-edge between two phases.
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.
