Biomaterials are specifically engineered to support tissue, nerve and muscle regeneration across the body, yet physicians and researchers have limited control over the size and connectivity of the internal pores that transfer oxygen and vital nutrients to where they are most needed. To solve this problem and better support tissue regeneration, a team at Penn State has designed a new class of tunable biomaterials.

Tiny thermometers offer on-chip temperature monitoring for processors

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To address this, a team led by researchers at Penn State has developed a microscopic thermometer, smaller than an ant’s antenna, that can be integrated onto a chip to accurately track temperatures.
