Penn-Rochester Study Identifies a Novel Way to Deliver Drugs to Control Dental Plaque

Therapeutic agents intended to reduce dental plaque and prevent tooth decay are often removed by saliva and the act of swallowing before they can take effect. But a team of researchers has developed a way to keep the drugs from being washed away.

Penn Researchers Use ‘Soft’ Nanoparticles to Model Behavior at Interfaces

blurb: 
By engineering nanoparticles that stick to an oil-water interface but not each other, Penn researchers have created a system that acts like a two-dimensional liquid.

Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule to stay there and behave predictably remains a challenge.

Penn Team Discovers New Liquid Crystal Configurations

blurb: 
Water-based liquid crystals are less well understood than their oil-based counterparts. New research advances the understanding of this class of materials by confining a water-based liquid crystal in a cylinder.

Oil-based liquid crystals are ubiquitous; a deep understanding of their properties is behind the displays found in most computer monitors, televisions and smartphones. Water-based liquid crystals are less well understood, though their biocompatibility makes them a potential candidate for a variety of biological and medical applications.

Swimming Algae Offer Penn Researchers Insights Into Living Fluid Dynamics

blurb: 
Very little is known about the dynamics of so-called “living fluids,” those containing cells, microorganisms or other biological structures. Penn researchers have shown how a model organism's swimming strokes change along with a fluid's elasticity.

 By Madeleine Stone  @themadstone

None of us would be alive if sperm cells didn’t know how to swim, or if the cilia in our lungs couldn’t prevent fluid buildup. But we know very little about the dynamics of so-called “living fluids,” those containing cells, microorganisms or other biological structures.

Penn Vet Team Points to New Colon Cancer Culprit

blurb: 
Colon cancer is a heavily studied disease — and for good reason. It is one of the leading causes of cancer-related deaths worldwide, and its numbers are on the rise, from 500,00 deaths in 1990 to 700,000 in 2010. This growth comes despite scientists’ ever-increasing knowledge of the genetic mutations that initiate and drive this disease. Now, a team of researchers from the University of Pennsylvania has found evidence of a new culprit in the disease, a protein called MSI2.

Penn and ExxonMobil Researchers Address Long-standing Mysteries Behind Anti-wear Motor Oil Additive

blurb: 
Motor oil contains chemical additives that extend how long engines can run without failure, but, despite decades of ubiquity, how such additives actually work to prevent this damage have remained a mystery.

The pistons in your car engine rub up against their cylinder walls thousands of times a minute; without lubrication in the form of motor oil, they and other parts of the engine would quickly wear away, causing engine failure.

Penn Researchers Develop Way of Making Light-bending ‘Raspberry-like Metamolecules’

blurb: 
Penn researchers have now devised a way of mass-producing metamaterials that exhibit magnetic resonance in optical frequencies.

The field of metamaterials is all about making structures that have physical properties that aren’t found in nature. Predicting what kinds of structures would have those traits is one challenge; physically fabricating them is quite another, as they often require precise arrangement of constituent materials on the smallest scales.

Penn Researchers Show How Rivers Creep and Flow to Shape Landscapes Over Time

blurb: 
Most models predict that rivers only transport sediment during conditions of high flow and, moreover, that only particles on the surface of the river bed move due to the force of the flowing water above. But using a custom laboratory apparatus, a new study by University of Pennsylvania researchers shows that, even when a river is calm, sediment on and beneath the river bed slowly creeps forward.

By Madeleine Stone  @themadstone

Rivers drive the evolution of Earth’s surface by eroding and depositing sediment.

But for nearly a century, geologists have puzzled over why theoretical models, which use principles of physics to predict patterns of sediment transport in rivers, have rarely matched observations from nature.

Penn Trustees Approve Design for Pennovation Center at Pennovation Works Site

The design development for the new Pennovation Center has received approval from the University of Pennsylvania Board of Trustees. This 58,000-square-foot, three-story facility is located in the heart of the Pennovation Works, Penn’s 23-acre site along the southern bank of the Schuylkill River and adjacent to the University campus.
