US faces rising death toll from wildfire smoke, study finds

Stanford University
Peer-Reviewed Publication

Wildfire smoke increasingly threatens lives across the country. A new study shows smoke exposure in the coming decades will cause tens of thousands of excess deaths and predicts where exposure will occur so communities and policymakers can prepare for the health burden.

Purdue study uncovers why some hurricanes balloon in size and what that means for forecasting future storms

Purdue University
Peer-Reviewed Publication

A new study led by Purdue University researchers has uncovered why some hurricanes grow significantly larger than others and why this growth occurs rapidly under certain ocean conditions. The research shows, for the first time, that hurricanes grow in size much faster when traveling over locally warm waters where the ocean surface is significantly warmer than the rest of the tropical oceans.

WMO report on global water resources: 2024 was characterized by both extreme drought and intense rainfall

Johannes Gutenberg Universitaet Mainz
Reports and Proceedings

In global terms, the past year was distinguished not only by extreme drought but also by unusually heavy rainfall. These are the core findings of the report of the World Meteorological Organization (WMO) on the status of our planet's water resources that was published today. Junior Professor Robert Reinecke of the Institute of Geography of Johannes Gutenberg University Mainz contributed to the report.

Biochar boosts black soil health and crop yields, study finds

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A long-term field study conducted in Northeast China’s fertile black soil region has demonstrated that biochar can significantly improve soil health, stabilize microbial communities, and increase crop yields—but only when applied at the right rate.

Engineers uncover why tiny particles form clusters in turbulent air

University at Buffalo
Peer-Reviewed Publication

716-645-4614

Tiny solid particles – like pollutants, cloud droplets and medicine powders – form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical mixers. What causes these extreme clusters – which make it more difficult to predict everything from the spread of wildfire smoke to finding the right combination of ingredients for more effective drugs – has puzzled scientists. A new University at Buffalo study, published Sept. 19 in Proceedings of the National Academy of Sciences, suggests the answer lies within the electric forces between particles.

BSC tests a pioneering system for immediate response to major disasters in Mexico's National Earthquake Drill

Barcelona Supercomputing Center
Business Announcement

The experiment, which will take place on 19 September, demonstrates the potential of high-performance computing infrastructures for emergency calculations, warning systems and urgent responses to extreme natural events.

Thanks to the exceptional allocation of supercomputing resources, unprecedented seismic simulation maps will be generated covering half of Mexico, one of the most seismically active areas on the planet.
