Florida’s Everglades face new threat as an invasive Asian swamp eel wipes out local crayfish and frogs and could be more destructive than the Burmese python |

Santanu3 weeks ago05 mins

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…

Goddard physicist Henry Plotkin inspects the retroreflector array destined for the 1964 Beacon Explorer A satellite, PC: Henry Plotkin/ Nasa On October 29, 1964, a team at NASA‘s Goddard Space Flight Centre in Greenbelt, Maryland, recorded the first successful laser returns from an artificial satellite. The target was Beacon Explorer B, also known as Explorer…

Since the 1980s, Florida’s biggest threat has been Burmese pythons; but this snake-like fish may be even worse for the Everglades ecosystem |

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…

For 30 years, the “Kerry cow” bones were seen as proof of early farming in Ireland; scientists now say they belonged to a bear and wild boar

Santanu3 weeks ago04 mins

Representative Image (AI-generated) For more than three decades, a collection of animal bones from Ireland’s Ferriter’s Cove was considered some of the earliest evidence that farming had reached the island. But new research has now overturned that interpretation. According to University College Dublin (UCD), bones once identified as cattle have instead been identified as belonging…

In 1972, Costa Rica began protecting a misty mountain forest: Decades later, Monteverde’s 10,500 hectares have become a remarkable conservation story |

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…

In 2014, scientists set off 23 explosions and deployed 3,500 seismographs around Mount St Helens; the experiment helped image a magma reservoir roughly 4 to 15 km beneath the volcano

Representative Image (AI-generated) Mount St. Helens is one of the most closely studied volcanoes in the United States, but scientists still cannot directly see the complex system of magma and rock hidden beneath it. In 2014, researchers launched an ambitious experiment to change that. According to the Imaging Magma Under St. Helens (iMUSH) project, a…

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…

Scientists turned plastic bottles and corn waste into protein-rich cookies; the food could help tackle hunger problem and also feed space crews

The technology could also potentially be used in places such as submarines and future human settlements on the Moon or Mars (American chemical society photo) Researchers at Southern Illinois University Carbondale (SIU Carbondale) are working on a technology that turns plastic waste from a water bottle into part of a cookie. For this, they programmed…

In 2020, 10-year-old Murphy Widdowson collected a spider on a remote Australian island that experts could not identify; scientists later declared it a new species and named it Artoriopsis murphyi after him

While on the remote island Murphy picked up a small spider that intrigued him, and he decided not to wonder what sort of spider he’d found, but to seek the opinion of an expert. For most kids, finding a spider would be a scream, and then a quick retreat. But for Murphy Widdowson, it was…
