The life aquatic: A game changer for frog vision, but little difference between night and day      (via sciencedaily.com)     Original source 

Frogs display a remarkable diversity of species as a whole, but does the same hold true for their visual abilities? A new study sought to answer this question by collaborating with researchers in Australia, Belgium, Brazil, Cameroon, Ecuador, Equatorial Guinea, French Guiana, Gabon, Seychelles, Sweden, United Kingdom and the United States, to get a sample of a diverse array of frogs to study the visual pigments found in their eyes. The researchers found this diversity is largely 'reflected' in the pigments, especially for aquatic frogs versus those living on the ground or in trees. They found little difference with the small groups of frogs that have adapted to daytime conditions as opposed to their nocturnal cousins.

Researchers envision sci-fi worlds involving changes to atmospheric water cycle      (via sciencedaily.com)     Original source 

Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.

Adult fish struggle to bounce back in marine protected areas      (via sciencedaily.com)     Original source 

Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.

'Tug of war' tactic enhances chemical separations for critical materials      (via sciencedaily.com)     Original source 

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

California leads U.S. emissions of little-known greenhouse gas      (via sciencedaily.com)     Original source 

California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride. As much as 17% of global emissions of this gas, a common pesticide for treating termites and other wood-infesting insects, stem from the United States. The majority of those emissions trace back to just a few counties in California, finds a new study.

New step in tectonic squeeze that turns seafloor into mountains      (via sciencedaily.com)     Original source 

Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.

Scientists' urgent call: End destruction and forge a just, sustainable future      (via sciencedaily.com)     Original source 

An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.

Older trees help to protect an endangered species      (via sciencedaily.com)     Original source 

The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.

Melting glaciers in a warmer climate provide new ground for invasive species      (via sciencedaily.com)     Original source 

In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.
