“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...

Pictured on the left is a spleen; on the right are red blood cells. ““We have presented results showing that the spleen is the main organ that defines the shape of the circulating red blood cells” says Ming Dao, a principal research scientist in MIT’s Department of Materials Science and Engineering.

How the spleen filters blood

Computer model finds slits in the spleen impose a “physical fitness test” on red blood cells.

A new report, “Convergence: The Future of Health,” draws on insights from scientists and researchers across academia, industry, and government. The cover of the report is an image of lungs, one of the major sites of metastasis. To help protect the lungs (blue) from this deadly process, bioengineers have created microscopic drug depots (red) to focus the effect of anti-cancer drugs that may hav...

In the top image, a neuronal axon (green) forms many synapses, highlighted in purple. The bottom image shows an axon from a fruit fly lacking the Shank protein. In these flies, not as many synapses form, and some of them (indicated by the white arrows) do not fully mature.

Neuroscientists illuminate role of autism-linked gene

Loss of Shank gene prevents neuronal synapses from properly maturing.

Mutualism, a phenomenon in which different species benefit from their interactions with each other, can help bacteria form drug-resistant communities. Pictured is an artist’s interpretation of mutualism among bacteria.

Teamwork enables bacterial survival

Strains of E. coli resistant to one antibiotic can protect other bacteria growing nearby.

MIT scientists say that the Great Oxygenation Event (GOE), a period that scientists believe marked the beginning of oxygen’s permanent presence in the atmosphere, started as early as 2.33 billion years ago.

Study pinpoints timing of oxygen’s first appearance in Earth’s atmosphere

Beginning 2.33 billion years ago, atmospheric oxygen built up in just 10 million years.
