By folding DNA into a virus-like structure, MIT researchers have designed HIV-like particles that provoke a strong immune response from human immune cells grown in a lab dish.

Engineers use “DNA origami” to identify vaccine design rules

In lab tests, virus-like DNA structures coated with viral proteins provoke a strong immune response in human B cells.

Photo shows the device the team developed. The tube at top is connected to a supply of the precursor material, sodium nitrite, which then passes through a channel in the fiber at the bottom and into the body, which also contains the electrodes to stimulate the release of nitric oxide. The electrodes are connected through the four-pin connector on the left.

Oxygen evolution reactions are important in a variety of industrial processes. A new study provides a detailed analysis of the process at a molecular level. As illustrated here, the researchers analyzed how molecules of water (H2O, left) are catalyzed by specific locations on a surface of ruthenium dioxide (center) to form molecules of oxygen (O2, right).

Study unveils details of how a widely used catalyst splits water

“Gold standard” material for generating oxygen from water divulges its molecular mechanisms.

White blood cells are among the first to mount an attack against sepsis, a deadly complication of Covid-19. In a project led by MIT Professor Daniela Rus, researchers are developing a machine learning system to detect an activated immune response to sepsis which could lead to earlier, more aggressive treatment. Here, a white blood cell attacks malaria.

Marshaling artificial intelligence in the fight against Covid-19

The MIT-IBM Watson AI Lab is funding 10 research projects aimed at addressing the health and economic consequences of the pandemic.

In this photograph of fabric, you can see the green light of functional fibers. “No human-made objects are more ubiquitous or exposed to more vital data than the clothes we all wear,” says doctoral student Gabriel Locke. “Wouldn’t it be great if we could somehow teach our fabrics to sense, store, analyze, extract and communicate this potentially useful information?”

3 Questions: The rapidly unfolding future of smart fabrics

Soon, your clothes may be able to monitor your vital signs, analyze the results, and warn you of health risks.
