Florida’s Everglades is facing a stealthy invasive threat beneath its waters as the Asian swamp eel spreads through wetlands and preys on fish, crayfish, frogs and other aquatic animals. The air-breathing fish, native to East and Southeast Asia, has been established in Florida for decades, but researchers are increasingly documenting severe ecological consequences in the…

In Florida’s canals and wetlands, some of the most consequential changes are difficult to see. An Asian swamp eel can spend much of its time buried in mud or hidden beneath vegetation, emerging to feed when water returns. That makes it very different from the Burmese pythons that have become a familiar symbol of the…

High in Costa Rica’s Tilarán mountains, the forest often appears to be suspended between land and sky. Mist moves through the trees, settles on leaves and mosses, and becomes part of the water moving down the slopes. At Monteverde, that moisture is not simply a feature of the scenery. The forest sits along the Continental…

Mars may be millions of kilometres from Minnesota, but for Cloquet student Jeremiah Bents, one small part of a future Mars mission could be tested much closer to home. Instead of looking at how to reach the Red Planet, Bents turned his attention to what astronauts might do once they get there, particularly when dealing…

Icebergs in Antarctica (Image Credit: Canva) Antarctica may look like a vast, frozen and unchanging landscape, but deep beneath its thick ice lies a surprisingly active world. In 2007, scientists reported findings based on measurements collected by NASA’s ICESat satellite between 2003 and 2006, revealing major changes in the surface of the West Antarctic Ice…

Leon Wang, the 17-year-old Connecticut student (Image Credit: Society For Science) Alzheimer’s disease remains one of the most difficult neurological disorders to treat, partly because the processes behind it can begin damaging brain cells long before symptoms become apparent. Now, a project by 17-year-old Connecticut student Leon Wang has drawn attention for exploring whether medicines…

Beneath the surface of the Great Barrier Reef, a 165-tonne building is being slowly reshaped by the environment around it. The Coral Greenhouse, an underwater installation at John Brewer Reef, was designed to work with the sea rather than simply sit on the seabed. Coral can grow across its surfaces, fish can move through its…

The Moon’s south pole may contain small pockets where some Earth microbes could remain alive after being carried there by astronauts or spacecraft. A new Nasa study has mapped parts of the region where five types of bacteria and fungi may withstand lunar conditions for at least a day, with the hardiest organism potentially lasting…

A major orange juice processing project in Brazil is taking an unusual approach to one of the industry’s biggest waste streams: turning citrus wastewater into renewable energy. Louis Dreyfus Company (LDC) is building what it describes as the world’s largest plant dedicated to producing biogas from citrus effluent at its industrial facility in Bebedouro, São…

In late 2028, Nasa plans to send something unusual towards Mars, a spacecraft carrying a working nuclear reactor designed to generate electricity for propulsion in deep space. Space Reactor-1 Freedom is intended to test nuclear electric propulsion beyond Earth orbit, where conventional solar power becomes increasingly difficult to use. The spacecraft will not land on…

For his project, Kang trained AI models to detect patterns associated with neurodevelopmental disorders from a large public dataset of retinal images. Instead of one approach, he used several techniques to improve the performance of the models. What if a simple picture of the eye could help doctors diagnose neurodevelopmental conditions earlier? For 17-year-old Edward…

A pile of discarded cashew shells would normally have little to do with international shipping. In Maharashtra agricultural leftovers are being fed into reactors that can turn them into usable fuel, gases and biochar. The technology comes from an unusual India-Denmark partnership built around the Viking biomass gasifier developed at the Technical University of Denmark….
