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.

President Gutmann Announces 2015 President’s Engagement Prize Winners at Penn

President Amy Gutmann today announced the selection of five undergraduates at the University of Pennsylvania as the inaugural President’s Engagement Prize recipients. Awarded annually to Penn students to design and undertake fully-funded local, national or global engagement projects during the first year after they graduate, the President’s Engagement Prizes underscore the high priority that Penn places on educating students to put their knowledge to work for the betterment of humankind.

New Penn Program Studies the Body’s Cells, One By One

blurb: 
The Penn Program in Single Cell Biology is a new effort by faculty members James Eberwine and Junhyong Kim to understand biology as it happens in each individual cell.

By Sarah Welsh

Cancer starts with a single cell going haywire. What is it about that one cell that makes it different from the rest, setting it on a path of destruction? A new program at the University of Pennsylvania may help find an answer to that and many other questions.

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.
