Political intimidation, at-risk media, and the future of journalism: A Q&A with Barbie Zelizer
In the wake of Saudi journalist Jamal Khashoggi’s death, Barbie Zelizer, director of the Center for Media at Risk, discusses how journalists and other digital media practitioners can better prepare for working in today’s climate and why, for that to happen, the media culture needs to shift.
Drivers of inflammation provide valuable targets for new gum disease therapies
A subset of T cells contributes to the inflammation and bone loss that characterizes periodontitis, a severe form of gum disease. According to new research by George Hajishengallis and scientists at the National Institutes of Health, drugs that specifically inhibit these cells may offer an effective therapy.
Immune cells involved in triple-negative breast cancer could offer future therapeutic target
New research led by Rumela Chakrabarti reveals how immune cells called myeloid-derived immunosuppressor cells contribute to the progression of triple-negative breast cancer, a particularly aggressive cancer. Pairing chemotherapy with a drug that blocks these cells may one day help stem its growth.
Electronic research notebooks streamline the scientific method
To do it right, scientific research requires careful record keeping, dutiful repetition of protocols, and, in many cases, free exchange of data. Electronic research notebooks are intended to help researchers up their game and are now available at no charge to the University community through the Office of the Vice Provost for Research, Dawn Bonnell.
A new take on the 19th-century skull collection of Samuel Morton
After unearthing and analyzing handwritten documentation from scientist Samuel Morton, doctoral candidate Paul Wolff Mitchell drew a new conclusion about the infamous 19th-century collection: Though Morton accurately measured the brain size of hundreds of human skulls, racist bias still plagued his science.
Making fossils move to build better robots
Aja Carter, a Ph.D. candidate in paleontology, builds robots based on fossilized animals that crawled out of the sea about 300 million years ago. She’s pioneering a new field that she calls paleo-bio-inspired robotics.
Seven Penn researchers receive NIH Director Awards
Seven researchers from the Perelman School of Medicine, School of Veterinary Medicine, and School of Engineering and Applied Science are to receive National Institutes of Health Director Awards, highly competitive grants to support innovative biomedical research.

Ventilating with mixture of helium and oxygen improves outcomes for horses in surgery
Horses are so large that their weight can cause their lungs to collapse while under anesthesia. In a new study, Klaus Hopster and colleagues at the School of Veterinary Medicine found that ventilating horses with a mixture of helium and oxygen can lead to better pulmonary gas exchange.
Teachers become students to become better teachers at GRASP Lab’s RET program
The Research Experiences for Teachers (RET) program run by the GRASP Lab in the School of Engineering and Applied Science is part of a larger National Science Foundation effort to get students interested in science and engineering at an early age. This summer, one cohort of students worked with robots in the Rehabilitation Robotics Lab at the Perelman School of Medicine.
