Bird beak revealed by laser imaging informs early beak function and development

Confuciusornis was a crow-like fossil bird that lived in the Cretaceous ~120 million years ago. It was one of the first birds to evolve a beak. Early beak evolution remains understudied. Using an imaging technique called Laser-Stimulated Fluorescence, researchers address this by revealing just how different the beak and jaw of Confuciusornis were compared to birds we see today.

CU Denver researcher analyzes the use of solar energy at US airports

(University of Colorado Denver) By studying 488 public airports in the United States, University of Colorado Denver School of Public Affairs researcher Serena Kim, PhD, found that 20% of them have adopted solar photovoltaic (PV), commonly known as solar panels, over the last decade.

Advancing the accurate tracking of energy poverty

(International Institute for Applied Systems Analysis) IIASA researchers have developed a novel measurement framework to track energy poverty that better aligns with the services people lack rather than capturing the mere absence of physical connections to a source of electricity. This alternative framework can aid better tracking of Sustainable Development Goal (SDG) 7 by virtue of its simplicity and sensitivity to the diversity in service conditions among the poor.
