Study reveals complex rupture process in surprising 2012 Sumatra quake

Analysis of seismic waves from the magnitude 8.7 earthquake reveals a complicated faulting process involving at least four faults at right angles to each other. The event was the largest intraplate earthquake ever recorded and involved horizontal motion on a series of faults in the middle of the Indo-Australian plate.

Singing in the brain

A Concordia researcher is developing a system that converts physiological displays of emotion into music.

By tapping into the brain's electrical signals, researchers can create an emotional symphony.

Retweeted health messages may not be what the patient ordered

A study by Penn State researchers found that people perceive tweets and retweets differently depending on the source, with original tweets from popular doctors being most credible. Non-medical professionals with a large following were also seen as more trustworthy than doctors who retweet health messages.

Loss of species makes nature more sensitive to climate change

A recent study found that climate change can exacerbate the negative effects of losing sensitive species, and that high biodiversity may be weaker than expected. This is particularly true for eelgrass meadows in shallow inlets, where a loss of cod and other predators can lead to an overgrowth of filamentous algae.
