MIT engineers have developed a telerobotic system to help surgeons quickly and remotely treat patients experiencing a stroke or aneurysm. With a modified joystick, surgeons in one hospital may control a robotic arm at another location to safely operate on a patient during a critical window of time that could save the patient’s life and […]

New tool reveals how immune cells find their targets
The human body has millions of unique B and T cells that roam the body, looking for microbial invaders. These immune cells’ ability to recognize harmful microbes is critical to successfully fighting off infection. MIT biological engineers have now devised an experimental tool that allows them to precisely pick out interactions between a particular immune […]
Study reveals the dynamics of human milk production
For the first time, MIT researchers have performed a large-scale, high-resolution study of the cells in breast milk, allowing them to track how these cells change over time in nursing mothers. By analyzing human breast milk produced between three days and nearly two years after childbirth, the researchers were able to identify a variety of […]
Study finds neurons that encode the outcomes of actions
When we make complex decisions, we have to take many factors into account. Some choices have a high payoff but carry potential risks; others are lower risk but may have a lower reward associated with them. A new study from MIT sheds light on the part of the brain that helps us make these types […]
New MRI probe can reveal more of the brain’s inner workings
Using a novel probe for functional magnetic resonance imaging (fMRI), MIT biological engineers have devised a way to monitor individual populations of neurons and reveal how they interact with each other. Similar to how the gears of a clock interact in specific ways to turn the clock’s hands, different parts of the brain interact to […]
Singing in the brain
For the first time, MIT neuroscientists have identified a population of neurons in the human brain that lights up when we hear singing, but not other types of music. These neurons, found in the auditory cortex, appear to respond to the specific combination of voice and music, but not to either regular speech or instrumental […]
Protein structure offers clues to drug-resistance mechanism
MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria become resistant to multiple antibiotics. Using nuclear magnetic resonance (NMR) spectroscopy, the researchers were able to determine how the structure of […]
Dendrites may help neurons perform complicated calculations
Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites — branch-like extensions that protrude from neurons — help to perform those computations. The researchers found that within a single neuron, different types of dendrites receive input from distinct parts of the brain, and process […]
A new atlas of cells that carry blood to the brain
While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain. Those cells, which comprise only 0.3 percent of the brain’s cells, also make […]
