At a southern Iraq site, unearthing the archaeological passing of time
When Holly Pittman and colleagues from the University of Pennsylvania and University of Pisa returned to Lagash in the fall of 2022 for a fourth season, they knew they’d find more than ceramic fragments and another kiln.
New cell characterization method hints at reasons for resistance to cancer therapies
Penn experts have developed new analysis tool that combines a cell’s unique gene expression data with information about the cell’s origins. The method can be applied to identify new cell subsets throughout development and better understand drug resistance.
Stable, faster computer memory storage
Researchers in the School of Arts & Sciences offer a new explanation for how certain materials can be grown on silicon and offer stable information storage at the nanometer scale for smaller, faster, more multifunctional processors.
Recreating the adrenal gland in a petri dish
A School of Veterinary Medicine–led team coaxed stem cells to take on the characteristics and functions of a human adrenal gland, progress that could lead to new therapies for adrenal insufficiencies and a deeper understanding of the genetics of such disorders.
Physics of disaster: How mudslides move
Researchers led by Douglas Jerolmack and Paulo Arratia used samples from the deadly 2018 Montecito mudslides to understand the complex forces at work in these disasters.
Defining neural ‘representation’
Neuroscientists frequently say that neural activity ‘represents’ certain phenomena, PIK Professor Konrad Kording and postdoc Ben Baker led a study that took a philosophical approach to tease out what the term means.
Environment influences coral’s resilience to acidification
Ocean acidification is an effect of climate change that threatens the health of coral. A new study examines how coral samples from the Great Barrier Reef fare in acidic conditions.
Targeting impulsivity early in adolescence could prevent later behavioral disorders
Tendencies toward impulsivity in early adolescence are linked with a variety of poor outcomes in later adolescence. By mid-adolescence, it may be too late to target impulsivity to prevent those developments.
A novel method for monitoring the ‘engine’ of pregnancy
By combining optical measurements with ultrasound, researchers were able to study oxygen levels in the placenta, paving the way for a better understanding of this complex, crucial organ.
Marrying models with experiments to build more efficient solar cells
Penn chemist Andrew M. Rappe, in collaboration with former postdoc Arvin Kakekhani and researchers at Princeton University, has gained insight into how the molecular make up of solar cells can affect their properties and make them more efficient.

Is an Alzheimer’s blood test right for me?
Postdoc Claire Erickson and Emily Largent of the Perelman School of Medicine and the Leonard Davis Institute discuss which people should take an Alzheimer’s blood test.

The brain may interpret smells from each nostril differently
A study by postdoc Gulce Nazli Dikecligil in the Perelman School of Medicine suggests that the smells flowing through each nostril are processed as two separate signals in the part of the brain that receives smell inputs.

One graceless tweet doesn’t warrant cancellation
Elle Lett, a postdoc in the Perelman School of Medicine, wrote about how the word “freak” has been used to dehumanize Black women. “There is a history that dates back to the antebellum South” of “fetishizing, hypersexualizing and otherizing Black women in freak shows and displays to media and even medical textbooks,” Lett wrote. “Black women are consistently dehumanized in America. By using ‘freak of nature,’ you separate Black women from the rest of human existence.”
