ITHACA, N.Y. -A new variety of broccoli called “NorthStar,” a co-hybrid between parents developed at Cornell University and the global seed company Bejo Zaden, can withstand warmer, more unpredictable conditions such as the ones in the Northeast growing region. The hybrid greatly expands the regions where broccoli can be grown, increasing food security, sustainability and access—while reducing the carbon and financial costs of shipping.

Georgia Tech and Vanderbilt researchers have developed the first lung-on-a-chip with a functioning immune system, a breakthrough published in Nature Biomedical Engineering. Led by Ankur Singh and Krishnendu “Krish” Roy, the team created a postage stamp–sized device where blood and immune cells circulate, fight infection, and heal, just as they would in a living lung. The advance not only provides unprecedented insight into diseases like influenza, asthma, and cancer but also offers a path toward reducing animal testing. Long-term, the technology could enable personalized medicine, with chips built from patients’ own cells to predict which therapies will work best.
