Penn Netter Center’s STEM Programs Promote Inclusion and Better Science

blurb: 
Amir Jones, a 10th grade student at West Philadelphia’s Sayre High School, has always had an interest in science, but partnership activities coordinated by Moelis Access Science, a program operated by the University of Pennsylvania’s Netter Center for Community Partnerships, helped his interests reach a whole new level.

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.

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 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 Scientists Describe the Function of an Enzyme Critical to Male Fertility

blurb: 
In a study published in the journal Genes and Development, University of Pennsylvania researchers have filled in details of how an enzyme, through interactions with a network of nearly two dozen other genes, protects the integrity of the germ line by giving rise to a class of RNA molecules that are essential to sperm development.

Researchers are one step closer to unraveling the extraordinarily complex series of processes that lead to an event crucial to human reproduction: the creation of sperm.

Penn Vet Researchers Identify Effective Treatment for Niemann Pick Type C

blurb: 
A study coming out in Science Translational Medicine and led by University of Pennsylvania School of Veterinary Medicine researchers has shown that cats with the rare disease Niemann Pick type C — which mirrors the human version of the disease — show vast improvements when treated with a compound called cyclodextrin.

Niemann Pick Disease type C, or NPC, is a disease most people have never heard of, affecting just one person in 150,000. Yet the disease is a devastating one. Frequently diagnosed in children in their elementary school years, sufferers usually die by the time they’re 20.
