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.
Studies of the energy-harvesting proteins in primitive cells suggest that key features of photosynthesis might have evolved a billion years earlier than scientists thought.
