New research from the Karolinska Institutet finds that a part of the immune system - the parasympathetic nervous system - may develop differently to what was previously thought.
Heavy alcohol use is known to lead to cognitive impairments. But for the first time, new research reveals how the brain may cause such impairments at a molecular level.

New study investigates whether there is a higher risk of infection when finding a sexual partner using a smartphone app, compared with online dating sites or meeting in person.
By measuring the EEG signals of monkeys learning a sorting task, MIT researchers have demonstrated how the brain forms new electrical circuits linking brain regions when learning.
The FDA released an update earlier this year, warning that statins increase risk of type 2 diabetes. Now, researchers have discovered why this is and offer a way to minimize risks.
Animal-assisted therapy is growing in popularity. But should there be more research in the field to better determine its benefits? And could it replace standard medication?
Ketamine could prevent suicide and lift mood in the severely depressed, according to new research that shows the effect is almost instantaneous and seems to work on most patients.
