“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.”

Feng Zhang of MIT and the Broad Institute was named a runner-up for TIME's 2016 Person of the Year for his work on CRISPR gene editing. Zhang shared the honor with Emmanuelle Charpentier at the Max Planck Institute in Berlin; Jennifer Doudna at the University of California at Berkeley; Carl June at the University of Pennsylvania; and Kathy Niakan at the Francis Crick Institute in London.

“…[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.

When cells suffer DNA damage, there are several different pathways that can kick in to help repair it, depending on the type of damage. Cells from different people and different tumors vary greatly in their ability to repair DNA damage, and scientists have been pursuing measurements of this ability as a way to predict how patients will respond to DNA-damaging chemotherapy.

Predicting cancer cells’ response to chemotherapy

Measuring DNA repair capability can reveal tumors’ sensitivity to drugs.
