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.
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.
Heat-Loving Microbes, Once Dormant, Thrive Over Decades-Old Fire
In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.
Researchers Rethink the Ancestry of Complex Cells
New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many.
How the Brain Links Gestures, Perception and Meaning
Neuroscience has found that gestures are not merely important as tools of expression but as guides of cognition and perception.
Biologists Discover Unknown Powers in Mighty Mitochondria
Mitochondria are most famous as sources of metabolic energy. But by splitting and combining, they can also release chemical signals to regulate cell activities, including the generation of neurons.
What Defines a Stem Cell? Scientists Rethink the Answer
As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.
‘Lava-Lamp’ Proteins May Help Cells Cheat Death
With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.
The Physics of Glass Opens a Window Into Biology
The physicist Lisa Manning studies the dynamics of glassy materials to understand embryonic development and disease.
