Johns Hopkins researchers report that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a “suicide gene” to pediatric brain tumor cells implanted in the brains of mice. The poly(beta-amino ester) nanoparticles, known as PBAEs, were part of a treatment that also used a drug to kill the cells and prolong the test animals’ survival.

In 2019, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory dove deeper into proton spin, took a leap in quantum communication, and uncovered new details of plant biochemistry, battery cathodes, catalysts, superconductors, and more. Here, in no particular order, are the biggest advances of the year.
