Penn Physicists Develop Force Law for Granular Impacts: Sand, Other Granular Matter's Behavior Is Better Defined

PHILADELPHIA -- Sand.  A single grain is tiny, but solid, and shares the physical properties of other solid matter.  But pack or transport millions of grains together - as modern society does with coffee grounds, flour and industrial chemicals - and granular materials act differently, baffling engineers.  They take the shape of their containers and flow freely, like liquids.

Like humans, naked mole-rats have regional accents

Robert Seyfarth of the School of Arts & Sciences weighed in on a new study that found naked mole-rat colonies have unique vocal signatures. “Mole-rats have this incredible society,” he said. “It looks like their vocal communication, and the way their brain organizes vocalizations, has evolved to fit the demands of that society.”

As more women enter science, it’s time to redefine mentorship

Danielle Bassett of the School of Engineering and Applied Science spoke about how same-gender mentorship can help aspiring female scientists navigate gender bias. “There’s clear evidence that, for many graduate students, having a shared gender with their mentor is something that’s important to them and allows them to succeed in ways that they couldn’t otherwise, because they have a role model,” she said.

Scientists identify the region of the brain associated with risk-taking—and it could explain why some people are more likely to smoke and drink

Gideon Nave of the Wharton School spoke about research he co-authored, which identified areas of the brain linked with risk-taking. “We find that we don’t have only one brain region that is the ‘risk area,’” he said. “There are a lot of regions involved.”

Extroverts have more success training their dogs than introverts

Lauren Powell of the School of Veterinary Medicine co-led a new study that explored the links between dog training and the personalities of dog owners. The most important factor affecting success, she said, was how bad the dog’s behavior was to begin with, but owner traits seem to play a role, too.

Businesses aim to pull greenhouse gases from the air. It’s a gamble

Jennifer Wilcox of the School of Engineering and Applied Science spoke about companies pledging to eliminate their carbon emissions within decades. “Carbon removal shouldn’t be seen as a get-out-of-jail-free card,” she said. “It has a role to play, particularly for sectors that are very difficult to decarbonize, but it shouldn’t be an excuse for everyone to keep emitting greenhouse gases indefinitely.”

Your dog may love you, but doesn't love the sight of your face, study finds

Carlo Siracusa of the School of Veterinary Medicine commented on a study that found dogs were more stimulated by seeing other dogs than people. “Mother Nature will not invest in something that is not relevant to survival, either in dog-to-dog or even wolf-to-wolf interactions,” he said. “They use other ways of communicating such as ear position—which can be seen from the front and from behind. The ear position will tell about the mood of the dog. We humans don’t move our ears.”
