A temperature gradient is applied to a CrSBr thin film to measure its thermoelectric response. Credit: Alessandra Canetta Thermoelectric systems are a green and sustainable way to harvest energy from any form of heat that would otherwise be wasted. At the core of this energy conversion process is the so-called Seebeck effect, which describes the … Read more
Here is an example of how the new model, AviTeam, can fill important knowledge gaps. The map at the top shows emissions from international aviation that were reported to the United Nations in 2019 under the UNFCCC treaty. The map below shows international aviation emissions from 197 countries, including those that did not report in … Read more

This article is part of Adam Frank’s series on Quantum Bayesianism, or QBism. Here are the links to parts 1, 2 and 3. Quantum mechanics is both our most powerful and strangest scientific theory. It is powerful because it offers exquisite control over the nanoworld of molecular, atomic, and subatomic phenomena. It’s strange because even … Read more
New York’s “asinine” climate change law requiring a dramatic increase in green energy has set unattainable goals and could lead to higher electricity costs for consumers, a leading advocate for state utilities says. “It’s very clear that New York will not meet the goals required by statute with regard to climate change,” said Paul Zuber, … Read more

New research led by the University of California, Irvine addresses a fundamental debate in astrophysics: Must invisible dark matter exist to explain how the Universe works the way it does, or can physicists explain how things work based solely on in the matter that we can directly? observe? Dark photons are hypothetical dark sector particles … Read more
