“We engineer new functions into cells. We try to give them new abilities,” PhD student Fahim Farzadfard says. “Basically, we’re making molecular tools. We try to understand cells inner-workings and engineer them using these tools.”

Endowing cells with new abilities

PhD student Fahim Farzadfard engineers cells to record “memories” of past events.

MIT earth scientists have found evidence that eukaryotes — the domain of life comprising animals, plants, and protists — were present on Earth as early as 2.33 billion years ago, right around the time when oxygen became a permanent fixture in the atmosphere.

Study suggests complex life was present on Earth 2.33 billion years ago

New estimate predates earliest fossil evidence by 800 million years.

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.

Researchers at MIT and other institutions have created tiny freeze-dried pellets that include all of the molecular machinery needed to translate DNA into proteins, which could form the basis for on-demand production of drugs and vaccines.

To produce biopharmaceuticals on demand, just add water

Freeze-dried cellular components can be rehydrated to churn out useful proteins.
