Scientists once believed that having many different plant species in grasslands kept food supplies steady. The idea was that if some plants struggled, others would thrive, balancing things out. But new research shows this doesn’t always work when climate change and human activity push ecosystems to
This March didn’t just break records in Dallas-Fort Worth—it smashed them. The average temperature reached 67. 4°F by the end of the month, beating the old 1907 record by less than a degree. Daytime highs were even more extreme, sitting a full degree above normal, while nighttime lows crept up by fo
Most people in Virginia don’t realize how much their daily lives rely on the water right outside their doors. Over half the state’s population lives near rivers, bays, or the ocean, meaning tides, fishing spots, and flood risks shape their routines more than they might think. Soon, a new set of tool
The state has poured more than $21 billion into a plan that aims to protect its shoreline. That money has funded research and engineering work that ranks among the world’s best in understanding how to save coastlines from erosion, sea‑level rise and industrial damage. Yet the people who should us
The spring of 2024 brought an odd burst of heat in March, a “false spring, ” before the air turned icy again. Researchers used silent recorders to track how four frog and toad species began calling in the wild from 2022 to 2025. The species studied were the boreal chorus frog, spring peeper, wood fr
Major League Soccer is shifting its calendar to a winter‑focused schedule next year. The change aims to keep teams out of the hottest months in southern cities while avoiding the harsh cold in northern markets. In practice, this means more games will be played during December and February in places
Fertilizers give crops the nitrogen they need, but when too much leaches into rivers it harms fish and plants. Scientists need to know how much nitrogen leaves fields each year to plan better solutions. Because real‑world data are scarce, researchers built a computer model that learns from all
The 2026 season opens in St. Louis under a scorching sky, with temperatures expected to top 90 degrees during the Cardinals game. These numbers edge close to the city’s 1991 record of 87 degrees and could surpass the all‑time March high of 92 set in 1929. Fans and players will face the peak he
The way the weather feels can change how our hearts work. When it is too hot or too cold, people are more likely to have heart attacks, strokes, sudden death and other serious problems. Scientists say the problem is getting worse because global temperatures are rising and extreme weather events ar
The new study shows that when temperatures drop, heart‑related deaths rise sharply across the United States. Researchers looked at data from 2000 to 2020 in 819 counties, covering about 80 % of adults over 25. They found that the safest temperature for heart health is around 23 °C (74 °F). When temp
