Plankton makes this dinosaur toy glow, batteries not required

As the story goes, the folks at BioPop were trying to make a sustainable light that relied on something other than man-made batteries. They tried using a bioluminescent plankton called dinoflagellates, but the tiny creatures required too much intervention to be a practical light source. They would, however, make for a really neat desk toy, and so the aptly-named Dino Pet was born.

Instead of inserting batteries or finding an available USB port, to kickstart the Dino Pet’s soft blue glow you simply need to make sure the dinoflagellates are properly fed and then given a good shaking.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
