Professor of city and regional planning Erick Guerra recently published a book exploring the economic and societal impacts of American highways. He explains some of the pitfalls associated with an ever-expansive highway system, arguing that spending more on highways might not be the solution to the country’s transportation issues.

Penn engineers and collaborators have developed a transparent, micro-engineered device that houses a living, vascularized model of human lung cancer—a “tumor on a chip”—and show that the diabetes drug vildagliptin helps more CAR T cells break through the tumor’s defenses and attack it effectively.

Xin Sun prepares samples collected from the Eastern Tropical North Pacific aboard a research vessel. By adding stable isotope tracers to these vials, Sun and her team can track how different microbial groups convert nitrogen compounds into nitrous oxide, revealing how subtle shifts in oxygen and organic matter change the ocean’s chemistry.

Collaborative research on the neural basis of chronic pain led by neuroscientist J. Nicholas Betley finds that a critical hub in the brainstem, has a built-in “off switch” to stop persistent pain signals from reaching the rest of the brain. Their findings could help clinicians better understand chronic pain. (Pictured) Flurorescence imaging reveals hunger neurons in the arcuate nucleus of the hypothalamus labeled in maroon with nuclei shown in blue.
