Two key ingredients cause extreme storms with destructive flooding – why these downpours are happening more often

  • Written by Shuang-Ye Wu, Professor of Geology and Environmental Geosciences, University of Dayton

A powerful storm system that stalled over states from Texas to Ohio for several days in early April 2025 wreaked havoc across the region, with deadly tornadoes, mudslides and flooding as rivers rose. More than a foot of rain fell in several areas.

As a climate scientist who studies the water cycle, I often get questions about how extreme storms...

While this theory may seem logical on its face, it’s a bit of a...

The founder kings of Silicon Valley: Dual-class stock gives US social media company controllers nearly as much power as ByteDance has over TikTok

  • Written by Gregory H. Shill, Professor of Law & Michael and Brenda Sandler Faculty Fellow in Corporate Law, University of Iowa

When Congress passed a law in 2024 to ban TikTok unless it came under U.S. ownership, lawmakers argued that the app’s Chinese parent company posed national security concerns. The Trump administration, which had granted the viral video app a reprieve shortly after taking office in January 2025, extended that pause again on April 4 after the...

Sleep deprivation is...

The ‘courage to be’ in uncertain times − how one 20th-century philosopher defined bravery

  • Written by Mordechai Gordon, Professor of Education, Quinnipiac University

Over the past few weeks, as negotiations for a ceasefire in Ukraine drag on, I’ve thought back to Feb. 28, 2025: the day of Volodymyr Zelenskyy’s heated visit to the Oval Office.
