When ancient technology and high-tech robots intersect
Stone Tool in Harold Dibble's Hand

Harold Dibble and his team research how humans might have made stone tools and flakes, from as far back as 2 million years ago to as recently as 10,000 years ago. 

When ancient technology and high-tech robots intersect

In one Penn lab, a stone-sculpting machine is helping archaeologists solve long-held mysteries of very old tools.

Risk tolerance linked to amygdala and prefrontal cortex brain regions

New research links willingness to take risks to brain structure and function, specifically the amygdala, the prefrontal cortex, and connections between the two.

Researchers show that cells’ perception of stiffness is a matter of time
Cell Stiffness

A cell can spread out more on a stiffer surface, making it easier for it to move, but the stiffness of its natural biological environment also changes in response. More realistic models of that interplay are necessary.

Researchers show that cells’ perception of stiffness is a matter of time

The relative stiffness of a cell’s environment is known to have a large effect on that cell’s behavior, including how well the cell can stick or move. Now, a new study by University of Pennsylvania researchers demonstrates the role timing plays in how cells perceive this stiffness.

A topological phenomenon could light the path toward faster optical communications

A new study led by University of Pennsylvania physicist Bo Zhen investigated topological phenomena in open, or non-Hermitian, physical systems which could potentially lead to faster connection speeds in optical communications.

Linking teen driving behaviors to ADHD, other mental health factors

Teen drivers are three times more likely to get into a fatal crash than their more-experienced counterparts. New research found a link between mistakes these new drivers make and self-reported ADHD.

Being hungry shuts off perception of chronic pain
Hunger and pain

Animals must respond to competing needs as they navigate their environment. Penn researchers found that hunger pathways selectively
suppress inflammatory pain in mice. (Art by Amber and Sam Alhadeff)

Being hungry shuts off perception of chronic pain

Finding food is a necessary survival skill, but so is avoiding pain. Research led by J. Nicholas Betley and postdoctoral researcher Amber Alhadeff showed that being hungry activates a neural pathway that inhibits the sensing and responding to chronic pain. The findings offer up new targets for treating pain.

Crowd-sourced map showcases campus accessibility in real time
Mark Bookman and Alice McGrath are the co-leads on a new map accessibility project.

Mark Bookman and Alice McGrath are spearheading the new accessibility mapping of the Penn campus.

Crowd-sourced map showcases campus accessibility in real time

Mark Bookman and Alice McGrath are on a quest to map physical and social barriers across campus. The goal is a crowd-sourced platform that automatically updates to present a real-time user accessibility resource.
