Liquid Crystal Turns Water Droplets Into ‘Gemstones,’ Penn Research Shows

blurb: 
A new study describes research into a type of liquid crystal that dissolves in water rather than avoids it as do the oily liquid crystals found in displays.

Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of liquids, characteristics that come together to enable the displays found in most computer monitors, televisions and smartphones.

Penn-Designed ‘Swiss Army Knife’ Molecule Captures RNA From Single Cells

blurb: 
A multi-disciplinary team from the University of Pennsylvania has published a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells.

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.

Penn Research Helps Lay Out Theory for Metamaterial That Acts as an Analog Computer

blurb: 
A study by researchers at the University of Pennsylvania, The University of Texas at Austin and University of Sannio in Italy, shows that metamaterials can be designed to do “photonic calculus” as a light wave goes through them.

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.

The ‘Personalized Advantage Index,’ a Decision-Making Tool, Developed at Penn

blurb: 
One of the primary social motivations for scientific research is the ability to make better decisions based on the results. Now, researchers at the University of Pennsylvania and the University of Pittsburgh have developed a decision-making model that compares and weights multiple variables.

Researchers at Penn Help Develop a Dynamic Model of Tissue Failure

blurb: 
Researchers at the University of Pennsylvania, Brown University and ETH Zurich have now used a series of experiments to develop a dynamic model of the stresses that stretch growing tissue. This model is the first to take into account the complicated feedback effects of cells’ molecular motors, which can respond to external stress by pulling harder on their environment, eventually tearing the tissue apart.

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.
