Climate lecture series will call for ‘unprecedented action,’ 1.5 minutes at a time
With a nod to the stated goal of the Paris Agreement of keeping global warming under 1.5 degrees Celsius to avoid the worst effects of climate change, a new 90-second lecture series kicks off today to give faculty and students a platform to briefly share how their work addresses climate change, and what we can do to help.
Researchers successfully transplanted a special type of lung cell called AT2 cells (labeled in green) from healthy mice into mice that had experienced a severe flu infection. The AT2 cells that engrafted (in red) appear to have helped the animals recover more robustly. (Image: Aaron Weiner/School of Veterinary Medicine)
Lung cell transplant boosts healing after the flu
A serious case of the flu can cause lasting damage to the lungs. In a study in mice, researchers found that transplanting cells from the lungs of healthy animals enhanced healing in others that had had a severe respiratory infection.
It was only three years ago that SEAS graduate student Barry Slaff (bottom left, waving hand) first tried dragon boat racing. This week he’s competing with paddlers from around the country at the World Dragon Boat Championships in Thailand. (Photo courtesy: Barry Slaff)
Dragon boating, on the world stage
Computer and information science doctoral student Barry Slaff trains six days a week for dragon boating on the Schuylkill River, and is headed to Thailand to compete in the World Dragon Boat Racing Championships.
People learn either by observing those around them or by innovating. A new study from Penn biologists Marco Smolla and Erol Akçay demonstrates how cultures can evolve based on what kind of learning and skills are required to thrive within them.
A society’s cultural practices shape the structure of its social networks
Biologists Erol Akçay and Marco Smolla used mathematical models to show that societies that favor generalists, who have a wide range of skills, are less well-connected than those societies that favor specialists, who are highly skilled at a smaller number of traits.
Rising senior Donnisa Edmonds (right) practices placing electrodes on her colleague to measure physiological responses. As part of her research with the EDEN lab, she tracks the physical responses of children as they perform a series of tasks.
An early start at research
As part of the Jumpstart for Juniors program through the Center for Undergraduate Research and Fellowships, rising seniors can spend the summer working with faculty on unique and fascinating projects.
Erynn Johnson monitors the progress of the lab’s 3D printer in Hayden Hall as it produces a resin-based replica of a snail shell. Her research, which relies on mathematical modeling paired with paleontology, gives insights into how shelled marine creatures that lived hundreds of millions of years ago evolved to withstand the crunching jaws of predators.
Making insights into ancient marine ecosystems with 3D-printed shells
If you’re a snail hoping to survive an encounter with a hungry fish, it helps to have a strong shell. Paleoecology doctoral student Erynn Johnson is using 3D printing to understand how predator-prey interactions may have played out hundreds of millions of years ago.
Mosquitoes infected with the parasite Crithidia fasciculata may offer a valuable model for studying other parasite diseases, according to a study led by Penn Vet’s Michael Povelones and Penn State Brandywine’s Megan Povelones. Here, a microscopic image shows the hindgut of Aedes aegypti mosquito infected with Crithidia expressing green fluorescent protein. (Image: Michael Povelones)
Keeping parasites from sticking to mosquito guts could block disease transmission
Researchers at the School of Veterinary Medicine show how a new model for studying the way parasites known as kinetoplastids adhere to mosquitoes’ insides could illuminate strategies for curbing diseases.
‘Smart aviary’ poised to break new ground in behavioral research
A collaboration that has brought together biologists, engineers, and physicists to study the reproductive behavior of birds using machine learning in a custom-built aviary at Pennovation Works.

With summer field course, students get their hands dirty learning about soils
Taught by the School of Arts and Sciences’ Alain Plante, Field Study of Soils gives students skills and familiarity with different soil types, including some on University property.
Researchers Scott Poethig and Aaron Leichty studied the development of ant-attracting traits in multiple species of acacia, including Vachellia collinsii. (Photo: Scott Poethig)
Timing is everything for the mutualistic relationship between ants and acacias
With a new insight into a long-described mutualistic relationship, plant biologists from the School of Arts and Sciences reveal the genetic factors and evolutionary forces that govern the development of the acacia’s ant-sustaining traits.
