NAU's Vulcan Project fossil fuel emissions show best match to carbon-14 measurements

The study found that NAU's Vulcan Project emissions estimate is the closest match to the new atmospheric-based approach, with an accuracy of 1.5%. The integrated approach combines multiple data sources, including local pollution reporting and fuel statistics, to provide a more detailed and accurate picture of US fossil fuel emissions.

Discoveries of high-Chern-number and high-temperature Chern insulator states

Researchers have discovered high-Chern-number and high-temperature Chern insulator states in MnBi2Te4 devices, exhibiting multiple dissipationless edge states above liquid helium temperature. Theoretical calculations reveal the origin of these states as a magnetic Weyl semimetal with layer-dependent Chern number.
