Nanosensors could help determine tumors’ ability to remodel tissue

Measuring enzyme levels could help doctors select appropriate treatments. MIT researchers have designed nanosensors that can profile tumors and may yield insight into how they will respond to certain therapies. The system is based on levels of enzymes called proteases, which cancer cells use to remodel their surroundings. Once adapted…

To produce biopharmaceuticals on demand, just add water

Freeze-dried cellular components can be rehydrated to churn out useful proteins. 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. The pellets, which…

Using light to control genome editing

New technique offers precise manipulation of when and where genes are targeted. The genome-editing system known as CRISPR allows scientists to delete or replace any target gene in a living cell. MIT researchers have now added an extra layer of control over when and where this gene editing occurs, by…
