Penn Physicists Help Create ‘Recipe Book’ for Building New Materials

PHILADELPHIA — By showing that tiny particles injected into a liquid crystal medium behave as predicted by existing mathematical theorems, physicists have opened the door for the creation of a host of new materials with properties that do not exist in nature.

The findings show that researchers can create a "recipe book" to build new materials of sorts using topology, a major mathematical field that describes the properties that do not change when an object is stretched, bent or otherwise “continuously deformed.”

Penn Study Details Dimmer Switch for Regulating Cell's Read of DNA Code

PHILADELPHIA — Epigenetics - the science of how gene activity can be altered without changes in the genetic code - plays a critical role in every aspect of life, from the differentiation of stem cells to the regulation of metabolism and growth of cancer cells.

Penn Study: Untreated Parkinson's Disease Patients No More Likely to Have Impulse Control Disorders

PHILADELPHIA — While approximately one in five Parkinson's disease patients experience impulse control disorder symptoms, the disease itself does not increase the risk of gambling, shopping, or other impulsivity symptoms, according to research from the Perelman School of Medicine at the University of Pennsylvania. A new study is the first to show in a large sample that people with untreated Parkinson's were no more likely to have an increased impulsivity than people without the disease.

Penn Study: Black and Hispanic Patients Less Likely to Complete Substance Abuse Treatment than White Patients

PHILADELPHIA — Roughly half of all black and Hispanic patients who enter publicly funded alcohol treatment programs complete treatment, compared to 62 percent of white patients, according to a new study from a team of researchers including the Perelman School of Medicine at the University of Pennsylvania. Comparable disparities were also identified for drug treatment program completion rates.

Penn Research Shows Mountains Are Only Minor Contributors to Sediment Erosion and Climate Regulation

PHILADELPHIA — Though churning smokestacks, cud-chewing cows and gasoline-burning vehicles are contributing constantly to greenhouse gas emissions, there are also many processes that do the reverse, pulling molecules like carbon dioxide out of the atmosphere. One of these is chemical weathering, which occurs when rock turns into soil. Carbon dioxide molecules and rain combine to dissolve rock, and the weathering products, including sediment, eventually make their way through waterways to the ocean where some become trapped on the ocean bottom and in coral reefs and seashells.
