Accelerometers around patients' necks capture data about the motions of their vocal folds to determine if their vocal behavior was normal or abnormal.

How machine learning can help with voice disorders

By detecting signs of vocal misuse, system from CSAIL and Mass General could eventually be used to help diagnose voice disorders.

Clownfish fight off predators of anemones that in turn provide habitats for the clownfish, an example of mutualism. But mutualistic relationships aren’t always set in stone; depending on environmental conditions, once-simpatico species can become competitors.

A mutual breakdown

Species relationships devolve from jointly beneficial to competitive in benign environments.

A new microfluidic device that replicates the neuromuscular junction — the vital connection where nerve meets muscle — contains a small cluster of neurons (green) and a single muscle fiber (red). A fluorescence image, bottom, shows the motor neurons sending out axons toward a muscle strip over a distance of about 1 millimeter.

A new, portable production system is designed to manufacture a range of biopharmaceuticals on demand. The principal component of the microbioreactor is a plastic chip with microfluidic circuits (green), optical sensors (red and blue circles) for monitoring oxygen and acidity, and a filter to retain the cells while the therapeutic protein is extracted (white circle).

“It’s intuitive that if a bunch of people are randomly walking around an area, the number of times they bump into each other will be a surrogate of the population density,” says Cameron Musco, an MIT graduate student in electrical engineering and computer science. “What we’re doing is giving a rigorous analysis behind that intuition, and also saying that the estimate is a very good estim...
