A type of geoengineering technology designed to oxidize atmospheric methane is not effective enough to reduce the impact of emissions, a new study has revealed. Atmospheric scientists at the University of Utah were not convinced of a recent proposal to put hydrogen peroxide into the atmosphere as a way to oxidize methane emissions and improve […]
For decades, 3M — a multibillion-dollar chemical company based in Minnesota — sold its firefighting foams as safe and biodegradable, while having knowledge that they contained toxic per- and polyfluoroalkyl substances (PFAS), according to newly uncovered documents, reported The Guardian. Starting in the 1960s and continuing until 2003, 3M’s firefighting foams contained perfluorooctanoic acid (PFOA) […]
The largest mountain range in Oregon, the majestic Cascades stretch from British Columbia, Canada, to Northern California. Scientists from University of Oregon (UO) and partners recently discovered a hidden gem beneath the Cascade range that is desperately needed in the West: water in volumes much higher than had previously been estimated. After mapping the amount […]
More than 97 million United States residents have been exposed to contaminants in their drinking water that are unregulated and could affect their health, a new analysis by Silent Spring Institute has found. Hispanic and Black communities have a higher likelihood of their water being contaminated by unsafe levels of toxic chemicals, a press release […]
An open letter calling for efforts to increase food production to avert a world hunger catastrophe has been signed by more than 150 winners of the Nobel and World Food Prizes. The signatories made a plea for political and financial backing to come up with “moonshot” technologies in the next quarter century, a press release […]
Like humans, animals experience complex emotions like empathy, love, grief and joy. They can also hold grudges. In a recent study, a team of biologists found that ants can learn from experience and hold grudges when confronted with competitors from another nest with whom they’ve had previous negative experiences. “We often have the idea that […]
Most spiders have eight legs, no ears and use fine leg hairs connected to nerve cells or their webs to hear sounds in their environment. But how do they smell? A new study by an international team of researchers has found that male spiders “smell” with their legs, using olfactory hairs — wall-pore sensilla — […]
Global sea temperatures reached an all-time high in 2024, according to a new study published Friday in the journal Advances in Atmospheric Sciences. The 54 researchers from seven countries deployed thousands of instruments to collect ocean data both at the surface and up to 2,000 meters below the surface — the latter called ocean heat […]
Fueled by the climate crisis, the global average temperature soared above the 1.5 degrees Celsius threshold for the first time in 2024, intensifying extreme weather. Experts from the United Nations World Meteorological Organization (WMO) have confirmed that last year was the planet’s hottest on record, reaching 1.55 degrees Celsius above the pre-industrial average, reported UN […]
