Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, according to a team of Penn State researchers.

The amount and composition of milk produced by dairy cows appears to be more regulated by internal, annual biological rhythms than by environmental factors such as heat and humidity, according to Penn State researchers who studied more than a decade of production records from herds across the country.

ZIF glasses, a new family of glass, could combine the transparency of silicate glass with the nonbrittle quality of metallic glass, according to researchers at Penn State and Cambridge University in the U.K.

Data breaches, hacked systems and hostage malware are frequently topics of evening news casts — including stories of department store, hospital, government and bank data leaking into unsavory hands — but now a team of engineers has an encryption key approach that is unclonable and not reverse-engineerable, protecting information even as computers become faster and nimbler.

A faster, more cost-efficient, and more accurate method of examining the effectiveness of human pluripotent stem-cell-derived cardiac muscle cells has been discovered, according to researchers from Penn State.
