Researchers produced colored images on culture plates by using red, green, and blue lights to control the pigment produced by bacteria with “multicolor vision.” The image has been color-corrected in Photoshop to improve contrast.

MIT engineers have devised a new way to analyze biologics as they are being produced. After proteins enter a nanofilter array device, they are directed to one side of the wall. This narrow line of proteins then encounters a series of slanted filters with tiny pores, designed so that smaller proteins will fit through them easily, while larger proteins will move along the diagonal for some distance ...

For their 2017 J-WAFS Seed Grant project, MIT professors Stephen Graves and Bishwapriya Sanyal will analyze irrigation practice, supply chain design, and extension services in Senegal. Their goal is to understand how policy and market conditions influence the availability of irrigation technologies in developing countries. Seen here: Irrigated rice cultivation in the Senegal River Valley.

J-WAFS awards $1.4 million in third round of seed grant funding

Principal investigators will receive grants of up to $200,000 per year for two years, overhead free, for innovative research on food and water challenges.

Mild heating of graphene oxide sheets makes it possible to bond particular compounds to the sheets’ surface, a new study shows. These compounds in turn select and bond with specific molecules of interest, including DNA and proteins, or even whole cells. In this image the treated graphene oxide on the right is nearly twice as efficient at capturing cells as the untreated material on the left.

Graphene sheets capture cells efficiently

New method could enable pinpoint diagnostics on individual blood cells.

A team of MIT biological engineers has developed a method to measure levels of the iron-containing protein heme inside the malaria parasite. “One of our long-term goals is ultimately being able to tie insights from these studies back to thinking about drug discovery and targeting pathways that regulate heme,” says Jacquin Niles, an MIT associate professor of biological engineering.
