How did demolishing four aging dams on a river straddling the Oregon and California border, in a project completed in 2024, become the largest dam removal in US history, and what did biologists find swimming upstream within weeks?

Four dams on the Oregon-California border came down in 2024, opening 420 miles of salmon habitat. Within a week of the final blast, sonar arrays detected Chinook moving upstream — and within weeks, they were spawning in Oregon tributaries.

The interstellar comet 3I/ATLAS, discovered over Chile in July 2025, may be more than 7.6 billion years old — roughly 3 billion years older than our solar system — and its speed and trajectory suggest it came from the Milky Way’s ancient thick-disk population, making it a possible relic of a planetary system that formed billions of years before ours

A visitor from the galaxy's dawn may have just arrived, carrying secrets about planetary systems that formed when the universe was young.

How does breaching a dike and removing a tide gate on a Pacific Northwest estuary let salt water back into diked pasture and bring juvenile salmon and sculpins into fields that had grown hay for decades?

Removing a single derelict tide gate on a Pacific Northwest estuary breaks a 140-year seal, lets salt water reclaim diked hayfields within one tidal cycle, and reopens miles of blind channels that juvenile Chinook, sculpins, and Dungeness crab colonize in their first migration season.

Sandhill cranes stage on Nebraska's Platte River each March in flocks approaching 1 million birds, roosting shoulder to shoulder on shallow sandbars the river only maintains because upstream irrigation withdrawals stop short of erasing its braided channel

Each March, more than a million sandhill cranes pack the shallow sandbars of Nebraska's Platte River in the single largest gathering of any crane species on Earth — a spectacle that depends on a braided channel the river barely still maintains.

Manatees in Florida's Crystal River gather by the hundreds each winter around freshwater springs that stay at a constant 72 degrees Fahrenheit, a thermal refuge that protects them from potentially fatal cold stress when Gulf water falls below 68 degrees

Every winter, hundreds of Florida manatees crowd into Crystal River's freshwater springs, where water flowing from the Floridan aquifer holds a constant 72 degrees. The margin between survival and cold stress is only four or five degrees, and the springs are what keeps them alive.
