Real-time sharing of Zika genomes: the race against a virus

As the global health emergency caused by the Zika outbreak continues, the virus underlying it remains a mystery, with devastating consequences still being identified. More than a year after Zika became widespread in the Americas, scientists have yet to fully unravel its trajectory across the continents, the scale and impact…

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…
