For centuries, lake sturgeon have moved quietly through the rivers and lakes of the Great Lakes region, growing slowly and aging in a way that has been difficult to measure. Their lives can stretch far beyond those of most freshwater fish, but just how far has remained uncertain. New research now suggests that some may…
In a vineyard in Italy’s Puglia region, rows of grapevines grew beneath something more usually associated with power stations than agriculture: photovoltaic panels. The arrangement changed the amount of sunlight reaching the vines, but it also altered what was happening much closer to the ground. Soil stayed wetter, temperatures were less extreme and the air…
Representative Image of an apple orchard with solar panels providing shade while generating electricity (AI-generated image) In 2022, researchers running a field experiment in southern France found that moving solar panels installed above an apple orchard sharply reduced sunburn damage on the fruit. The system, known as a dynamic agrivoltaic setup, tilts photovoltaic panels through…
A $12 million research project at Penn State is trying to give drones a new way of making decisions, drawing inspiration from the small brains of insects and other animals. Funded by the US Army’s Army Research Laboratory, the project aims to develop an onboard sensing system that can pick out useful information without sending…
Snow-covered mountain ranges of the Montagne Noire. Image Credit: Von Christian Ferrer/Wikipedia Nearly 400 fossils discovered in southern France are giving scientists a detailed view of marine life that lived close to the South Pole about 470 million years ago. The fossils belong to the newly described Cabrières Biota, an Early Ordovician fossil site in…
What happened to the reindeer on St. Matthew Island is a classic story of wildlife boom and bust. In 1944, the US Coast Guard corralled 29 Nunivak Island reindeer on a barge and floated the animals north to the island, more than 200 miles away to one of the most remote places in Alaska. While…
PC: 3M Young Scientist Lab Dry air is not completely without water. There is moisture suspended in the atmosphere even when rainfall is scarce, and 13-year-old Aniket Sarkar wanted to find out whether some of it could be recovered for agriculture. His idea led to a low-cost atmospheric water capture system built with ordinary materials,…
Harmful algal blooms can turn freshwater ecosystems into dangerous environments, but researchers at Florida Atlantic University are developing a novel way to tackle one of the nutrients that helps drive them, excess phosphorus. Rather than removing algae after a bloom has already formed, the team is developing 3D-printed adsorbent structures designed to capture phosphate directly…
Invasive Species: Why Are Asian Carp a Problem? An intensive 28-year eradication campaign has eliminated common carp from two major Tasmanian lakes, achieving what fisheries experts around the world once considered almost impossible in a large, open freshwater system. The Tasmanian Inland Fisheries Service (IFS) has officially declared European carp (Cyprinus carpio) functionally eradicated from…
On Ishigaki Island, cane toads have been living in conditions quite different from those faced by the populations from which they came. The island is warm, wet and separated from mainland habitats, and the animals introduced there in the late 1970s have now had several decades to establish themselves. When scientists compared these Japanese toads…
