Researchers at Princeton engineering have created a semiconductor with unique properties: it is just a few molecules thick and can repeatedly change its properties in response to light. This is a step toward building more energy-efficient sensors, optoelectronic devices and computing technologies.

The Land Institute and HudsonAlpha Institute for Biotechnology have assembled the first chromosome-scale, haplotype-phased genomes for Silphium integrifolium (rosinweed, silflower) and Silphium perfoliatum (cup plant, silphie). The findings are published in the journal Nature Communications. This landmark research promises to expand and accelerate the development of more climate-resilient, sustainable perennial crops for food, fiber, forage, and medicines.

Traditional field research combined with new technology has revealed a secret to the survival of juvenile salmon as they form in their eggs, especially in low-water years when many do not survive, new research from NOAA Fisheries and the University of California, Davis shows.
