Scientists plan the resurrection of an animal that's been extinct since 1936

This as fascinating as it is creepy...

Unfortunately, however, white light generation by newer technologies such as light-emitting diodes (LEDs) is not straightforward and often relies on a category of materials called "rare-earth metals," which are increasingly scarce. This has recently led scientists to look for ways to produce white light more sustainably. Researchers at Giessen University, the University of Marburg, and Karlsruhe Institute of Technology have recently uncovered a new class of material called a "cluster glass" that shows great potential for replacing LEDs in many applications.

"We are witnessing the birth of white-light generation technology that can replace current light sources. It brings all the requirements that our society asks for: availability of resources, sustainability, biocompatibility," said Prof. Dr. Simone Sanna, Giessen University Professor and lead computational researcher on the project.

"My colleagues from the experimental sciences, who observed this unexpected white light generation, asked for theoretical support. Cluster glass has an incredible optical response, but we don't understand why. Computational methods can help to understand those mechanisms. This is exactly the challenge that theoreticians want to face."

During the COVID-19 pandemic, the link between politics and health became glaringly obvious. Democrat-leaning “blue” states were more likely to enact mask requirements and vaccine and social distancing mandates. Republican-leaning “red” states were much more resistant to health measures. The consequences of those differences emerged by the end of 2020, when rates of hospitalization and death from COVID rose in conservative counties and dropped in liberal ones. That divergence continued through 2021, when vaccines became widely available. And although the highly transmissible Omicron variant narrowed the gap in infection rates, hospitalization and death rates, which are dramatically reduced by vaccines, remain higher in Republican-leaning parts of the country.

But COVID is only the latest chapter in the story of politics and health. “COVID has really magnified what had already been brewing in American society, which was that, based on where you lived, your risk of death was much different,” says Haider J. Warraich, a physician and researcher at the VA Boston Healthcare System and Brigham and Women’s Hospital in Boston.
