Penn was built on the concept of innovation. “If it’s new, novel and holds promise to change the world,” says President Amy Gutmann, “you’ll find it at Penn.”
Unraveling the brain’s reward circuits
Unraveling the brain’s reward circuits
Food, alcohol, and certain drugs all act to reduce the activity of hunger neurons and to release reward signals in the brain, but alcohol and drugs rely on a different pathway than does food.

A Q&A with inorganic chemist Eric Schelter about the chemical reactions that create explosive displays and how different metals are used to create bright and brilliant colors.
Protein-linked sugars are crucial for the uptake of proteins linked to Parkinson’s disease
Protein-linked sugars are crucial for the uptake of proteins linked to Parkinson’s disease
A new study shows that glycoproteins, proteins with added sugar molecules, impact how neurons uptake alpha-synuclein, a protein that clusters together and can lead to Parkinson’s disease.

A Q&A with biomaterials engineer Shu Yang about the real-life technologies and research that could allow people to climb up walls and synthesize their own superstrong spider silk.
What influences how parents and their gay adolescent sons talk about sexual health at home?
What influences how parents and their gay adolescent sons talk about sexual health at home?
Research from Penn found that even when parent-child conversations avoid heteronormative stereotypes, outside factors like mass media and religion—those beyond the parents’ control—can reinforce them.
A new drug target for chemically induced Parkinson’s disease
A new drug target for chemically induced Parkinson’s disease
An enzyme that modifies chemicals formed in the body by alcohol, tobacco, and certain foods may be a new target for treating Parkinson’s disease. The altered compounds may play a role in triggering the onset or advancing the progression of the neurodegenerative condition.
Toxins from the tap
Toxins from the tap
In Pennsylvania and hundreds of other locations around the country, manmade chemicals known as PFAS have been found in drinking water. Howard Neukrug discusses the potential harm, how local and federal agencies are responding, and the many related questions that remain unanswered.

Wheels, drones and Rescue Randy: DARPA robotics competition puts mine rescue to the test
A four-legged robot from the School of Engineering and Applied Science was among robots performing underwater search and rescue in a competition. “They're doing everything completely autonomously, so every step they take is kind of a minor victory for us,” said C. J. Taylor. “We always feel that we could do better. We learn so much from each of these events and that gives us new ideas about things that we want to try.”

‘Why not fly over it?’ Uber picks New Jersey firms in ambitious bid to beat traffic congestion
Rahul Mangharam of the School of Engineering and Applied Science commented on Uber’s new air taxi venture. “It’s going to be a very congested sky,” he said. “You want to make sure that each flight plan is safe by design, and that even if they do mess up for some reason, they have a fallback option.”

A feisty Google adversary tests how much people care about privacy
Joseph Turow of the Annenberg School for Communication commented on DuckDuckGo, a privacy-focused search engine. “I’m almost embarrassed to say that I don’t use it more than I do,” he said. “There is something in my head that tells me I’ll get a better search from Google, even when I don’t know if that is demonstrably correct or not.”

This freaky robotic fish is powered by ‘blood’
James Pikul of the School of Engineering and Applied Science co-authored a study in which researchers developed a soft, robotic lionfish powered by a blood-like compound. “This robot blood is our first demonstration of storing energy in a fluid that is normally only used for actuation,” he said.

How the mind emerges from the brain’s complex networks
Danielle Bassett of the School of Engineering and Applied Science co-authored an article about network neuroscience, which allows us to see the origins of mental activity in the brain. One day, they write, “a neuroscientist who knew all the principles of brain function and everything about someone’s brain could predict that person’s mental conditions—the future, as well as the past, would be present inside the person’s mind.”

Domestication made dogs’ facial anatomy more fetching to humans
James Serpell of the School of Veterinary Medicine said humans may have bred dogs to appear more infantile over time. “We are innately predisposed to respond with a kind of nurturing behavior towards certain physical characteristics,” he said. “Over time, [humans selected] for traits that satisfy that parental nurturing response.”
