Interdisciplinary research at the University of Pennsylvania is showing how cells interact over long distances within fibrous tissue, like that associated with many diseases of the liver, lungs and other organs.
At the turn of the millennium, the cost to sequence a single human genome exceeded $50 million, and the process took a decade to complete. Microbes have genomes, too, and the first reference genome for a malaria parasite was completed in 2002 at a cost of roughly $15 million. But today researchers can sequence a genome in a single afternoon for just a few thousand dollars.
Glass is mysterious. It is a broad class of materials that extends well beyond the everyday window pane, but one thing that these disparate glasses seem to have in common is that they have nothing in common when it comes to their internal structures, especially in contrast with highly ordered and patterned crystals.
A new chemical-genetic therapy restores light responses to the retinas of blind mice and dogs and enables the mice to guide their behavior according to visual cues, setting the stage for clinical trial in humans.

Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind the paper-folding art can also be applied to making a microfluidic device for a blood test, or for storing a satellite's solar panel in a rocket’s cargo bay.
Penn Research Suggests That Men Have Accurate Perception of Women’s Sexual Interest, Overconfidence Is Not Adaptive
Overconfidence sounds like an inherently bad trait to have, but when it comes to natural selection, some evolutionary psychologists have suggested it could be advantageous in finding a mate.
Metamaterials, precisely designed composite materials that have properties not found in natural ones, could be used to make light-bending invisibility cloaks, flat lenses and other otherwise impossible devices.
