New hybrid machine learning forecasts lake ecosystem responses to climate change

Mon, 2022-07-11 14:38
Through the middle of the 20th century, phosphorus inputs from detergents and fertilizers degraded the water quality of Switzerland's Lake Geneva, spurring officials to take action in the 1970s to remediate the pollution. "The obvious remedy was to…

Discovery pushes back the earliest record of wildfire by 10 million years

Mon, 2022-07-11 14:36
While wildfires in recent years have raged across much of the Western United States and pose significant hazards to wildlife and human populations, fires have been a long-standing part of Earth's systems without the influence of humans for hundreds…

Mysterious radio bursts from space detected

Thu, 2022-07-07 11:47
Astronomers using the U.S. National Science Foundation's Karl G. Jansky Very Large Array, or VLA, as well as other powerful telescopes have found the second known highly active, repeating fast radio burst, or FRB, raising more questions about the…

Citizen science project analyzes data to model treetop snowpack and predict melt

Thu, 2022-07-07 11:43
Participants in a citizen science project, created by University of Washington researchers and funded in part by the U.S. National Science Foundation, viewed time-lapse images from Colorado and Washington and tagged photos that had trees with snow on…

Study shows that 'green islands' help forests regenerate after fire

Wed, 2022-07-06 10:51
Thanks to trends like mountain snowpack loss, drier summers and longer fire seasons, high-elevation forests in the Cascade Range of the Pacific Northwest are burning more frequently and extensively than in the past. Increased fire damage has prompted…

Pigment or optical illusion? What makes this berry blue

Wed, 2022-07-06 10:42
Miranda Sinnott-Armstrong was walking down Pearl Street in Boulder, Colorado, when something caught her eye: a small, particularly shiny blue fruit, on a shrub known as Lantana strigocamara. While its tiny clusters of pink, yellow and orange flowers…

Scientists discover uncertainties in flood risk estimates

Tue, 2022-07-05 09:46
Flood frequency analysis is a technique used to estimate flood risk, providing statistics such as "100-year flood" and "500-year flood" forecasts that are critical to infrastructure design, dam safety analysis and flood mapping in flood-prone areas…

Bringing magma up to our feet in Antarctica

Tue, 2022-07-05 09:41
Antarctica has long been a land of mystery and heroic feats made famous by the explorations of James Ross and Roald Amundsen, Robert Scott and Ernest Shackleton. A key piece of the puzzle for understanding global continental evolution, Antarctica is…
