With impressive accuracy, dogs can sniff out coronavirus
In a proof-of-concept study led by the School of Veterinary Medicine, dogs identified positive samples with 96% accuracy.
From ‘Indiana Jones’ to medieval robots
Historian of science Elly Truitt’s multidisciplinary investigations of the Middle Ages challenge assumptions about the period as a dark time in innovation and prompt a rethink of notions of ‘modern’ science.
Beyond topological insulators
Charlie Kane and Eugene Mele’s groundbreaking theories on the existence of a new class of materials continues to inspire an upcoming generation of physics researchers.
27 million galaxy morphologies quantified and cataloged with the help of machine learning
Using data from the Dark Energy Survey, researchers from the Department of Physics & Astronomy produced the largest catalog of galaxy morphology classifications to date.
Toward a better understanding of ‘fake news’
PIK Professor Duncan Watts publishes a framework for developing a comprehensive research agenda to study the origins, nature, and consequences of misinformation on democracy.
The power of architecture to address public health and environmental crises
Two new studies, one on UV sterilization in occupied rooms and another on radiative cooling, show how architecture can help create interior spaces that are both COVID-safe and energy-efficient.
Even without a brain, metal-eating robots can search for food
SEAS engineers are developing robot-powered technology with energy sources that are harvested in the robot’s environment.
Developing a new platform for DNA sequencing
Research from the lab of Marija Drndić in the School of Arts & Sciences shows how solid state materials can be developed for large-scale automated sequencing by incorporating state-of-the-art fabrication and analytics.
Turning back the clock on a severe vision disorder
Gene therapy triggered the regrowth of healthy photoreceptor cells and restored vision in dogs with a severe form of Leber congenital amaurosis.
How cells transport molecules with ‘active carpets’
New research provides insights into the process of diffusion in living systems, with implications from novel active coatings to understanding how pathogens are cleared from lungs.

Neuralink’s monkey can play Pong with its mind. Imagine what humans could do with the same technology
Anna Wexler of the Perelman School of Medicine expressed skepticism about Neuralink, a company developing brain-machine interfaces. “Neuroscience is far from understanding how the mind works, much less having the ability to decode it,” she said.

University of Penn nursing student co-creates product to help frontline workers care for patients in the dark
Anthony Scarpone-Lambert, a senior in the School of Nursing, spoke about the wearable nightlight he helped develop. The invention allows nurses to check on patients at night without turning on bright white lights. "On average, patients regularly report poor quality of sleep as their number one complaint during hospitalization," he said.

7 women scientists who defied the odds and changed science forever
Ashley Wallace of the School of Engineering and Applied Science spoke about Kizzmekia Corbett, a viral immunologist who co-developed Moderna’s COVID-19 vaccine. "The pandemic exposed layers of racial disparities in medical treatment and clinical research, resulting in conversations surrounding the effects of how COVID-19 disproportionately infects and kills people of color," said Wallace. "Dr. Corbett is not only advancing science but she is also using her voice and platform to contribute to these conversations."
