Ethicists and biologists seek to head off challenges raised by tissue “organoids” as they become increasingly similar to human brains.
Modern humans and Neanderthals commingled at many points in history, raising the possibility that the ancient hominins were just another version of us.
During development, cells seem to use statistics to figure out what identities they should take on.
Humans interbred with Neanderthals and Denisovans, but were there others? Paleontologists are using deep learning to find lost branches of our family tree.
The brain’s way of processing smells is inspiring scientists to rethink how we design machine learning algorithms.
Cells can reprogram themselves after an injury much more radically than people thought, reverting to a stem cell-like state.
The computer scientist Barbara Engelhardt develops machine-learning models and methods to scour human genomes for the elusive causes and mechanisms of disease.
For the first time, researchers can see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression.
The dizzying network of interactions within microbe communities can defy analysis. But a new approach simplifies the math.
The findings add to the longstanding debate over which were the first self-replicating molecules
