Millions of people with diabetes are forced to endure multiple finger pricks daily — an unpleasant practice that may impede compliance, and whose reliability is operator-dependent.
Now, Dr. Paul Barone and Dr. Michael Strano at the MIT Department of Chemical Engineering are developing a new approach to glucose monitoring.
Building on work they previously published in ACS Nano, the new technology employs a nanoparticle “tattoo” as a glucose sensor, which can then be continuously monitored by a device on the surface of the body. Read more »

Research scientists at MIT have been studying the right temporo-parietal junction (TPJ) region of the brain that seems to be involved in judging the behavior of other people. With the help of transcranial magnetic stimulation (TMS) applied to the region, they were able to affect the moral conclusions that people reached when analyzing the actions of others.
From MIT news office:
The researchers used a noninvasive technique known as transcranial magnetic stimulation (TMS) to selectively interfere with brain activity in the right TPJ. A magnetic field applied to a small area of the skull creates weak electric currents that impede nearby brain cells’ ability to fire normally, but the effect is only temporary.
In one experiment, volunteers were exposed to TMS for 25 minutes before taking a test in which they read a series of scenarios and made moral judgments of characters’ actions on a scale of one (absolutely forbidden) to seven (absolutely permissible). Read more »

To the delight of video game enthusiasts, a new study coming out of MIT has discovered a relationship between the size of certain structures in the brain and the ability to perform in video games. The researchers analyzed the size of specific brain regions of the participants using high-resolution MRI. They then had participants play Space Fortress, (pictured) a game that makes Asteroids look like a technological marvel.
Here is more from the press release:
Half of the study participants were asked to focus on maximizing their overall score in a video game while paying equal attention to the various components of the game. The other participants had to periodically shift priorities, improving their skills in one area for a period of time while also maximizing their success at the other tasks. The latter approach, called “variable priority training,” encourages the kind of flexibility in decision-making that is commonly required in daily life, according to Kramer. Read more »
