Young male rats can recognize rats they’ve recently met, whereas young females treat new acquaintances like strangers, research shows.

A new flexible electrode array can detect the activity of neurons in a rat’s brain at high resolution for more than a year.

Rats missing UBE3A, the gene mutated in people with Angelman syndrome, squeak frequently but tend not to be responsive to the play and squeaks of other rats.

Lovastatin, a drug that lowers cholesterol levels, prevents memory and learning problems in a rat model of fragile X syndrome.
