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…
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…

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…

In 1967, NASA sent flour beetle pupae into space aboard the Biosatellite II experiment to examine how spaceflight and radiation could affect insect development. The mission exposed the insects to conditions that could not easily be reproduced on the ground, allowing researchers to compare their development with that of ground controls. One of the clearest…
Image Credit: AI Generated Scientists have identified a previously unknown species of fungus after isolating it from the faeces of a giant panda. Named ‘Mucor melanoleucus,’ it belongs to a group of fungi commonly found in soil and decaying organic material. To work out exactly where it belonged, researchers examined its physical features, observed how…
A restored 25-acre coastal wetland on the southern shore of western Lake Erie was used continuously by millions of aquatic animals after it was reconnected to nearby waterways, according to a four-year acoustic monitoring study led by researchers at the United States Geological Survey (USGS). The scientific assessment, published in the journal Aquatic Ecosystem Health…

Beneath its frozen surface, cracking ice, marine mammals and passing ships create a constantly changing underwater soundscape. For scientists trying to understand this…
Image: AI representation of a way to turn astronaut poop into a sterile, odour-free material that could be recycled For astronauts travelling far beyond Earth, even the most ordinary human waste becomes a serious engineering problem. On a long-duration mission, there is no convenient rubbish collection, unlimited storage space or easy way to send unwanted…
Dog waste is usually treated as an unpleasant urban problem, something to be collected, bagged and thrown away. But researchers are investigating whether it could instead become a source of renewable energy. A new study has examined dog faeces as a feedstock for producing biohydrogen and methane through anaerobic biological processes. The research, published in…
