Penn Researchers Use Network Science to Help Pinpoint Source of Seizures
For the third of all epilepsy patients who don’t respond to medication, an alternative is to locate the small cluster of neurons that act as the seed of a seizure’s aberrant electrical activity and surgically remove it. Unfortunately, such surgeries often fail to bring any relief.
Penn Biologists-in-training Used Genomic Techniques to Study Campus Microbes
The premier scientists at the University of Pennsylvania rely on next-generation sequencing techniques to elicit new information about the living world. Now, freshmen can do the same thing.
East Antarctic Ice Sheet Has Stayed Frozen for 14 Million Years, Penn Team Reports
Antarctica was once a balmier place, lush with plants and lakes. Figuring out just how long the continent has been a barren, cold desert of ice can give clues as to how Antarctica responded to the effects of past climates and can perhaps also indicate what to expect there as Earth’s atmospheric concentration of carbon dioxide grows.
Kindness, Charitable Behavior Influenced by Amygdala, Penn Research Reveals
The amygdala, a small structure at the front end of the brain’s temporal lobe, has long been associated with negative behaviors generally, and specifically with fear. But new research from Michael Platt, the James S.
Your Brain’s Take on Public Health Campaigns
Mass media campaigns have proven to influence people’s health-related decision making—for better or for worse. Effective messaging has helped millions quit smoking, exercise more, and eat better, while failed campaigns have backfired, sometimes even causing those with unhealthy habits to dig deeper into their vices.
Eye-on-a-Chip Represents New Way To Do Disease Research
A clump of cells in a Petri dish may have the same DNA as their counterparts in the body, but most of the similarities end there.
Penn Researchers Make Thinnest Plates That Can Be Picked Up by Hand
Scientists and engineers are engaged in a global race to make new materials that are as thin, light and strong as possible. These properties can be achieved by designing materials at the atomic level, but they are only useful if they can leave the carefully controlled conditions of a lab.
Gene Pair Plays Crucial Role in Colon Cancer, Penn Vet Team Shows
Colon cancer is one of the leading causes of cancer-related deaths worldwide, and researchers are hard at work to understand the disease’s complex molecular underpinnings.
Teens Know Dangers of Driving and Cellphone Use, Yet Do It Anyway, Penn Research Shows
What happens when “Tom Hanks,” “Tom Cruise” and “Kesha” sit around a table? When the talkers are actually teens using researcher-requested pseudonyms they chose to anonymously discuss their driving habits, the results are surprising, maybe even more so than if the real celebrities got together.

Man does DNA test, not prepared for what comes back ‘unusually high’
César de la Fuente of the School of Engineering and Applied Science and Perelman School of Medicine says that Neanderthal DNA provides insights into human evolution, population dynamics, and genetic adaptations, including correlations with traits such as immunity and susceptibility to diseases.

My Climate Story: Philly students take science from abstract to personal
The “My Climate Story” project at the Environmental Humanities Department helps students and teachers learn about climate change’s impact in everyday backyards, with remarks from Bethany Wiggin. The idea is credited to María Villarreal, a College of Arts and Sciences second-year from Tampico, Mexico.

Here’s why experts don’t think cloud seeding played a role in Dubai’s downpour
Michael Mann of the School of Arts & Sciences says that many people blaming cloud seeding for Dubai storms are climate change deniers trying to divert attention from what’s really happening.

Can we stop AI hallucinations? And do we even want to?
Chris Callison-Burch of the School of Engineering and Applied Science says that auto-regressive generation can make it difficult for language learning models to perform fact-based or symbolic reasoning.

“Record-shattering” heat wave in Antarctica — yep, climate change is the culprit
Michael Mann of the School of Arts & Sciences says that persistent summer weather extremes like heat waves are becoming more common as people continue to warm the planet with carbon pollution.

How the solar eclipse will affect solar panels and the grid
Benjamin Lee of the School of Engineering and Applied Science says that the electrical grid will have to figure out how to match supply and demand during brief windows where the energy source goes away.

Scientists struggle to explain ‘really weird’ spike in world temperatures
Michael Mann of the School of Arts & Sciences says that tendencies to exaggerate climate science in favor of “doomist” narratives helps no one except the fossil fuel industry.
