Southern California anglers are seeing an unusual number of warm-water fish as rising ocean temperatures linked to El Niño and marine heatwaves bring species typically found farther south into local waters.Fishermen working in Marina del Rey and Santa Monica are catching fish species, in larger sizes, that are rarely seen in the area.

A man who decided to keep every piece of plastic he threw away for an entire year ended up with a collection of 4,490 pieces, turning a simple personal experiment into a wider effort to reduce everyday plastic waste. Instead of allowing wrappers, packaging and other discarded items to disappear into the bin, he saved…
Almost 10 years after the tanks went under, researchers from Ramkhamhaeng University in Bangkok did some diving to see what had grown up around the man-made reef sites. Battle tank is made for war. It is built to cross tough terrain, take a beating and dominate a battlefield. But what if the battlefield disappears and…
Waste coffee grounds and discarded oyster shells could be turned into a useful construction material. The mixture used spent coffee grounds (SCG) as its main filler, with oyster shells added to strengthen the granular structure and GGBS-based alkali-activated materials used as the binder. Because SCG particles are highly compressible, the researchers added oyster shells in…
Wyoming tetons Representative image from Canva Deep in the rock record of Wyoming, a layer of fossil leaves tells a quiet but powerful story about what happens to forests when the planet warms rapidly. About 56 million years ago, during a spike in global temperatures known as the Paleocene Eocene Thermal Maximum (PETM), a lush…
Soldiers on both sides stand behind fences and in between are thousands of landmines. For more than 70 years, humans have not ventured into a 155-mile-long corridor that divides two nations, North and South Korea. While boundaries and borders can ward people off, nature is above all such regulations. This is probably why a space…
Tiger worm toilets are designed to turn human waste into vermicompost using worms that feed on and break down organic material. The approach can reduce the amount of waste that builds up in a toilet and has been studied as a form of non-sewered sanitation. Researchers tested whether tiger worms could destroy Ascaris eggs under…
A thirsty bat sweeps over a pond, listens to the echoes returning from its surface and drops closer to drink. But what happens when that same acoustic signal comes from something that only looks like water to its echolocation system? Scientists have found that bats can be surprisingly easy to fool. In controlled experiments, smooth…

Image Credit: David Moffatt In 2022, Australian ecologist Dr Luke Carpenter-Bundhoo set out to study how the Black Summer bushfires had affected ecosystems in K’gari, Queensland. Instead, while surveying a creek, he encountered an unexpected creature: an eel-like fish with seven gills and a mouth lined with circular rows of teeth. The…
PC: University of Nebraska–Lincoln From university laboratories in Germany to beetle specimens collected from dung in China, Patrick Urban’s career has focused on insects that are easy to overlook. The German biologist specialises in dung beetle taxonomy and ecology, with particular attention to the Onthophagini group found across the Palearctic and Indomalayan regions. His work…
