A multi-disciplinary team from the University of Pennsylvania has published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connections influence individual cell function and overall protein production.

Red blood cells are the body’s true shape shifters, perhaps the most malleable of all cell types, transforming – among many other forms -- into compressed discs capable of going through capillaries with diameters smaller than the blood cell itself. While studying how blood clots contract John W.
A new study from Penn Medicine epidemiologists that looked at four years of bed bug reports to the city of Philadelphia found that infestations have been increasing and were at their highest in August and lowest in February. The findings, published ahead of print on January 8 in the Journal of Medical Entomology, point to two possible peak times to strike and eliminate the bugs.
The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical “metatronic” devices that can manipulate light in the way electronic circuitry manipulates the flow of electrons.
One of the primary social motivations for scientific research is the ability to make better decisions based on the results.
A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures.
Sleep, or the lack of it, seems to affect just about every aspect of human physiology.
A new study suggests a potential dietary treatment - a cocktail of key amino acids that improved sleep disturbances caused by brain injuries in mice - for millions of people affected by traumatic brain injury (TBI)—a condition that is currently untreatable.
The idea of growing replacement tissue to repair an organ, or to swap it out for an entirely new one, is rapidly transitioning from science fiction to fact.
Ragini Verma of the Perelman School of Medicine is cited for studying brain differences between men and women.
