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.

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.

“The challenge is to engineer a system where we get enough growth to have a productive microbial ‘ chemical factory’ but not so much that we can’ t channel enough of the sugars into a pathway to make large quantities of our target molecules,”says Kristala Prather, an associate professor of chemical engineering at MIT.

Kevin Kung, a Tata Fellow and PhD candidate in biological engineering, feeds rice husks into the torrefaction reactor in his lab at MIT. A thermochemical process will convert the biomass to a more energy-dense form, making it easier to transport and use as fuel.

Tapping the hidden value of farm waste

MIT researchers are developing mobile torrefaction technology that can convert biomass into clean-burning fuel, unlocking potential income for farmers.

“Diesel is the preferred fuel because of its high energy density and the high efficiency of the engines that run on diesel,” professor Gregory Stephanopoulos says. “The problem with diesel is that so far it is entirely made from fossil fuels.”

“…[I]f humans behave similarly to mice in response to this treatment, I would say the potential is just enormous, because it’s so noninvasive, and it’s so accessible,” says Li-Huei Tsai, the Picower Professor of Neuroscience, when describing a new treatment for Alzheimer’s disease.
