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…

Arctic ice with flags of countries participating in Operation Ice Camp 2026 and Havguard’s communications device, enclosed in a polycarbonate pressure vessel The Arctic sea is becoming noisier and harder to reach. Beneath its frozen surface, cracking ice, marine mammals and passing ships create a constantly changing underwater soundscape. For scientists trying to understand this…

Representative Image (AI-generated) What happens when young forest communities spend more than a decade growing in air with unusually high levels of carbon dioxide and ozone? Scientists in Wisconsin set out to find the answer by changing the atmosphere around these communities and tracking how the trees responded over 11 years. The experiment, known as…

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…

Dogs may be doing more than simply choosing a spot when they stop for a break. A 2013 study by Czech researchers found that dogs tended to align their bodies along Earth’s North-South magnetic axis while defecating, but only when the planet’s magnetic field was relatively stable. The research involved 70 dogs from 37 breeds,…
