What riverbeds have in common with mixed nuts
The surface of a riverbed is typically lined by relatively large rocks, which protect the layers of finer sand and gravel beneath from erosion. Geologists have long thought that fluid mechanics control this pattern; the idea being that the flow of the river washes away the finer particles from the bed’s surface, leaving the larger particles behind.
Coalition Seeks to Increase Transparency on Life Sciences Career Prospects
Nine American research universities and a major cancer institute today announced plans to give would-be life scientists clear, standardized data on graduate school admissions, education and training opportunities and career prospects.
Penn Students Take on Peace, Water and Climate, First in Norway and Next in Ghana
One way to learn about climate change is to read about it, exploring the scientific literature, perusing science news and combing through reams of relevant data. Another way is to experience it firsthand.
New Dental Material Resists Plaque and Kills Microbes, Penn Dental Team Finds
Dentists rely on composite materials to perform restorative procedures, such as filling cavities. Yet these materials, like tooth enamel, can be vulnerable to the growth of plaque, the sticky biofilm that leads to tooth decay.
Seeing Isn’t Believing: Penn Biologists Show How to Shut Off Hunger ‘Alarm System’
Imagine you’re in a restaurant, hungry, anxious and a bit irritable awaiting your food order to arrive at the table. The server exits the kitchen with a tray full of steaming plates and a flood of relief washes over you.
Improving oral cancer diagnosis on many fronts
A comprehensive dental visit includes more than a cleaning and X-rays; well-trained dentists know they must also take a thorough look inside the oral cavity to spot any potentially unusual lesions that could signal oral cancer.
Penn Junior Jack Stack Is Pursuing His Paleontological Dream
Some paleontologists travel far and wide to seek new fossils — to the desert Southwest of the United States, remote regions of China or the farthest tip of Argentina. University of Pennslyvania student Jack Stack, on the other hand, made his first paleontological discoveries much closer to home.At home, in fact.
‘Brazil Nut Effect’ Helps Explain How Rivers Resist Erosion, Penn Team Finds
Pop the top off a can of mixed nuts and, chances are, Brazil nuts will be at the top. This phenomenon, of large particles tending to rise to the top of mixtures while small particles tend to sink down, is popularly known as the “Brazil nut effect” and more technically as granular segregation.
