For selenium in rivers, timing matters
Selenium contamination of freshwater ecosystems is an ongoing environmental health problem around the world. A naturally occurring trace element, selenium levels are high in some geologic formations like sedimentary shales that form much of the bedro.....»»
Research finds geochemical landscape drives musk oxen reproductive success
Researchers have studied Greenland musk oxen that have been followed for 25 years to see how their feeding habits affect their reproductive success. And it turns out that when they go to areas with more copper and selenium in the ground, they have mo.....»»
Walleye struggle with changes to timing of spring thaw, researchers find
Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of th.....»»
Scientists propose new method for tracking elusive origins of CO₂ emissions from streams
A team of researchers from the University of Massachusetts Amherst that specializes in accounting for the carbon dioxide release by streams, rivers and lakes has recently demonstrated that the chemical process known as "carbonate buffering" can accou.....»»
South Africa"s apartheid legacy is still hobbling research—a study of geography shows how

How governments handle data matters for inclusion
Governments increasingly rely on large amounts of data to provide services ranging from mobility and air quality to child welfare and policing programs. While governments have always relied on data, their increasing use of algorithms and artificial i.....»»
Scientists improve timing of fog warnings by detecting changes in atmospheric electric field
A foggy day in London town just got even more predictable. Scientists have discovered how to increase early warnings for fog, from around half an hour to up to two hours before it happens, by detecting changes in the atmospheric electric field......»»
New method measures levels of toxic tire particles in rivers
Scientists at the UK Centre for Ecology & Hydrology (UKCEH) have developed a robust method for detecting whether a toxic chemical used in car tires is present in rivers, streams, and lakes and measuring its concentrations......»»
Detecting atmospheric rivers with satellite observations
Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a cha.....»»

Fish in the upper Danube could be just as endangered in the future as in the past, but for different reasons
Rivers belong to the most threatened ecosystems on Earth. While many studies have projected climate change effects on species, little is known about the severity of these changes compared to historical alterations......»»
The escalating impact of global warming on atmospheric rivers
Ribbons of water vapor called atmospheric rivers wind through the troposphere, moving the planet's moisture from near the equator toward the poles. These aerial waterways are responsible for about 20%–30% of the annual rain and snow in parts of Eur.....»»
El Niño is starting to lose strength after fueling a hot, stormy year. An atmospheric scientist explains what"s ahead
Wild weather has been roiling North America for the past few months, thanks in part to a strong El Niño that sent temperatures surging in 2023. The climate phenomenon fed atmospheric rivers drenching the West Coast and contributed to summer's extrem.....»»
Ghana: Kumasi city"s unplanned boom is destroying two rivers—sewage, heavy metals and chemical pollution detected
Ghana's urban population has more than tripled in the past three decades, from 4 million to nearly 14 million people. Competition for land in cities has increased among various land uses. These trends have led to encroachment in ecologically sensitiv.....»»
Why Apple Vision Pro"s constant strobing matters to your health

Q&A: Climate expert explains why atmospheric rivers are causing historic rainfall in California
In December 1861, intense rainfall began pounding central California, thrashing the state for the next 43 days. The rain, which scientists now think was caused by atmospheric rivers, killed thousands of people and destroyed the state's economy, trans.....»»
Ultrasound can save fish in hydropower rivers
The phenomenon of gas supersaturation occurs when air enters water-filled hydropower inlets and is then exposed to high pressure. When this water is subsequently released into the river below the hydropower plant, it's almost like opening a bottle of.....»»
Microplastics found in Nile River"s tilapia fish
The Nile is one of the world's most famous rivers. It's also Africa's most important freshwater system. About 300 million people live in the 11 countries it flows through. Many rely on its waters for agriculture and fishing to make a living......»»
The limits of weather forecasting: How far into the future can we look?
Weather-related disasters and climatological extremes, including rivers bursting their banks and flooding as well as heat waves and droughts, cause tragic loss of life and cost billions of dollars in property damage each year......»»
Microbial division of labor produces higher biofuel yields
Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach, detailed in the journal Nature Communications, relies on careful timing and a tight division.....»»
