A Strange Grid Pattern in the Gobi Desert | What On Earth? (Full Episode)

Images of earth from space reveal an intimate portrait of human activity. Cities glow bright while the wilderness remains dark. Why then is the Australian outback, lit up like a series of vast cities? Also, what’s behind a strange grid pattern in the middle of the Gobi Desert. Stream Full Episodes of What on Earth?: […]

A tech intervention to tame tuberculosis

For tuberculosis patients, complying with a full course of treatment can be daunting and difficult. But a new experiment conducted by MIT researchers in Kenya, in collaboration with the digital health company Keheala, shows that a digital program used on mobile phones helps patients successfully finish their treatments. The program created interactive communication between patients […]

How “information gerrymandering” influences voters

Many voters today seem to live in partisan bubbles, where they receive only partial information about how others feel regarding political issues. Now, an experiment developed in part by MIT researchers sheds light on how this phenomenon influences people when they vote. The experiment, which placed participants in simulated elections, found not only that communication […]

“Nanoemulsion” gels offer new way to deliver drugs through the skin

MIT chemical engineers have devised a new way to create very tiny droplets of one liquid suspended within another liquid, known as nanoemulsions. Such emulsions are similar to the mixture that forms when you shake an oil-and-vinegar salad dressing, but with much smaller droplets. Their tiny size allows them to remain stable for relatively long […]

Using gene editing, neuroscientists develop a new model for autism

Using the genome-editing system CRISPR, researchers at MIT and in China have engineered macaque monkeys to express a gene mutation linked to autism and other neurodevelopmental disorders in humans. These monkeys show some behavioral traits and brain connectivity patterns similar to those seen in humans with these conditions. Mouse studies of autism and other neurodevelopmental […]

How we tune out distractions

Imagine trying to focus on a friend’s voice at a noisy party, or blocking out the phone conversation of the person sitting next to you on the bus while you try to read. Both of these tasks require your brain to somehow suppress the distracting signal so you can focus on your chosen input. MIT […]

How a declining environment affects populations

Stable ecosystems occasionally experience events that cause widespread death — for example, bacteria in the human gut may be wiped out by antibiotics, or ocean life may be depleted by overfishing. A new study from MIT physicists reveals how these events affect dynamics between different species within a community. In their studies, performed in bacteria, […]

Why visual stimulation may work against Alzheimer’s

Several years ago, MIT neuroscientists showed that they could dramatically reduce the amyloid plaques seen in mice with Alzheimer’s disease simply by exposing the animals to light flickering at a specific frequency. In a new study, the researchers have found that this treatment has widespread effects at the cellular level, and it helps not just […]

Mapping the brain at high resolution

Researchers have developed a new way to image the brain with unprecedented resolution and speed. Using this approach, they can locate individual neurons, trace connections between them, and visualize organelles inside neurons, over large volumes of brain tissue. The new technology combines a method for expanding brain tissue, making it possible to image at higher […]
