A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens. As neural networks learn, they adopt patterns of activity that are strikingly similar to real-life neuron firing patterns. What’s more, the type of training affects both the activity pattern, and the ability to solve a task, in similar ways between neural networks and living brains.

Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease. Scientists said more work is needed to determine whether targeting the molecule would be safe and effective in people.

KRAS inhibitors shrank existing NF1-related nerve tumors and prevented new tumors from forming in a mouse model that closely mirrors the human disease, according to new research led by experts at Cincinnati Children's.
