Signs of Covid-19 may be hidden in speech signals

It’s often easy to tell when colleagues are struggling with a cold — they sound sick. Maybe their voices are lower or have a nasally tone. Infections change the quality of our voices in various ways. But MIT Lincoln Laboratory researchers are detecting these changes in Covid-19 patients even when these changes are too subtle […]


Nine MIT School of Science professors receive tenure for 2020

Beginning July 1, nine faculty members in the MIT School of Science have been granted tenure by MIT. They are appointed in the departments of Brain and Cognitive Sciences, Chemistry, Mathematics, and Physics. Physicist Ibrahim Cisse investigates living cells to reveal and study collective behaviors and biomolecular phase transitions at the resolution of single molecules. […]


Producing a gaseous messenger molecule inside the body, on demand

Nitric oxide is an important signaling molecule in the body, with a role in building nervous system connections that contribute to learning and memory. It also functions as a messenger in the cardiovascular and immune systems. But it has been difficult for researchers to study exactly what its role is in these systems and how […]


A focused approach to imaging neural activity in the brain

When neurons fire an electrical impulse, they also experience a surge of calcium ions. By measuring those surges, researchers can indirectly monitor neuron activity, helping them to study the role of individual neurons in many different brain functions. One drawback to this technique is the crosstalk generated by the axons and dendrites that extend from […]


COMMANDing drug delivery

While we are starting to get a handle on drugs and therapeutics that might to help alleviate brain disorders, efficient delivery remains a roadblock to tackling these devastating diseases. Research from the Graybiel, Cima, and Langer labs now uses a computational approach, one that accounts for the irregular shape of the target brain region, to […]


Universal musical harmony

Many forms of Western music make use of harmony, or the sound created by certain pairs of notes. A longstanding question is why some combinations of notes are perceived as pleasant while others sound jarring to the ear. Are the combinations we favor a universal phenomenon? Or are they specific to Western culture? Through intrepid […]

Turning lemons into lemonade

When it was announced that all non-research staff were to work from home I think we were all in shock – well, I was in shock. I always envisioned my role as being tied to actually being on campus in our building.  That said, our headquarters packed up in record time and in one day […]
