Drug improves social deficits in fragile X syndrome
A drug called arbaclofen improves behavioral problems in people with fragile X syndrome, an inherited condition that can lead to mental retardation and autism, according to the results of a clinical trial published today in Science Translational Medicine. A second study published in the same journal showed that the drug restores normal brain function in a mouse model of the disorder.

Mass-produced science is coming. What happens to scientists?
Artificial intelligence may soon enable researchers to generate high-quality science at a previously unimaginable speed. For science consumers—the public, medical patients, technology users—the likely effects will be positive. For scientists, the effects will be as disruptive as industrial mass production was for artisan manufacturers.
