It's a question that a University of Maryland economist is asking about the United States, where unprecedented levels of despair have manifested in a national mental health crisis, a surge in opioid abuse and suicide, and increased workforce dropout.
Ashes of orca Tokitae finally home after her death last month in Miami
Money Heist is the most watched Spanish series of all time thanks to Netflix, which launched it internationally after purchasing it from Atresmedia. The last episode premiered in autumn 2021, a few weeks after the North American company began broadcasting Squid Game, the South Korean series that became the most viewed content on the platform. These successes are no coincidence.

How does voltage drive nonmetallic catalysts to perform electrocatalytic reactions?
Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands' carbon storage and reduce the amount of climate-warming carbon dioxide (CO2) and methane they release back into the atmosphere during dry periods by up to 90%, a new Duke University study finds.
Companies in Germany are adapting to the consequences of extreme weather events
Understanding how voltage drives nanoscale electrocatalysts to initiate reactions is a fundamental scientific question. This is especially challenging when dealing with non-metallic electrocatalysts due to their low inherent carrier concentration, which leads to poor conductivity. When voltage is applied at the non-metal/solution interface, the situation becomes more complex than in the case of...

This is revealed by the current IfM survey of more than 1,300 managing executives on the current Climate Adaptation Week of the Federal Ministry for the Environment.
Generating homozygous mutant populations of barley microspores by ethyl methanesulfonate treatment
As energy demand continues to rise, research into new, efficient renewable and clean energy sources is an urgent priority. Currently, renewable energy sources like solar, wind, tide, and geothermal make up less than 40% of the current energy demand. Increasing this percentage and reducing the amount of fossil fuels used will require other, more efficient renewable and clean energy sources.

Improving air quality forecasting with daily update of emission inventory
If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations of stars after that. So our search for the first stars of the cosmos is a search for our own history. While we haven't captured the light of those first stars, some of their...
How air pollution is making life tougher for bugs
In the realm of air quality forecasting, the precision of predictions largely hinges on the accuracy of emission inventory data.
