Scientists warmed a Colorado grassland for 29 years, but shrubs increased 150% while grasses and wildflowers fell 28% |

Representative Image of a subalpine grassland transitioning from grasses to shrubs under warming conditions over 29 years (AI Generated Image) A 29-year climate-warming experiment in Colorado has documented a major shift in a subalpine grassland, with shrubs increasing by 150% while grasses and forbs, including wildflowers, declined by about 28%. The findings come from one…

Engineers dredged 500,000 cubic yards of sand from the Mississippi River and used it to build seven islands; six years later, the $25 million McGregor Lake project has restored 270 acres of aquatic habitat and protected 22 acres of wetlands

For years, sand dredged from the Mississippi River was removed to keep one of America’s most important waterways navigable. At one restoration site, engineers found another use for that material, building islands. The US Army Corps of Engineers has completed a $25 million habitat restoration project at McGregor Lake in Wisconsin, where about 500,000 cubic…

Two dead stars orbit each other every 6.2 minutes; their orbit is shrinking faster than in two other known systems |

Representative Image of a pair of white dwarfs orbiting closely, surrounded by a cosmic background and X-ray emissions (AI Generated Image) An international team led by Indian astronomers has identified a pair of white dwarfs locked in an extraordinarily tight orbit that is shrinking faster than that of two other well-known systems of the same…

Solar farms with taller grass, wildflowers and hedgerows supported more birds; study recorded 35.1 per 4 hectares |

PC: Dr Joshua Copping/ University of Cambridge Solar farms can provide renewable electricity while also supporting wildlife when managed carefully. A study of six solar farms in the East Anglian Fens found that bird abundance and species richness varied with site management. Researchers surveyed 23.2 km of transects across the solar farms and 15.2 km…

In 2001, California began removing non-native trout from high-Sierra lakes; by 2011 nearly 44,000 fish were removed from 19 lakes, as frogs in three restoration lakes rose from about 190 to over 18,800

High in California’s Sierra Nevada, a conservation project changed the future of a disappearing amphibian. In 2001, staff at Sequoia and Kings Canyon National Parks began removing non-native trout from selected lakes and streams, restoring water bodies that had historically been home to mountain yellow-legged frogs but were naturally fishless. By 2011, nearly 44,000 trout…

For 29 years, scientists warmed a mountain meadow by 2°C; shrubs increased 150% while mycorrhizal fungi declined |

Representative Image of a subalpine meadow shifting from herbaceous plants to shrub-dominated vegetation due to climate warming (AI-generated image) For 29 years, researchers artificially warmed a subalpine meadow at the Rocky Mountain Biological Laboratory in Gothic, Colorado, to examine how sustained temperature increases affect ecosystems above and below ground. The results, published in the Proceedings…

Scientists turned carbon dioxide into high-performance polyester; the material can be chemically recycled into reusable building blocks |

Carbon dioxide is abundant but chemically inert, which makes it difficult to turn into useful polymers. A study describes a closed-loop platform that uses carbon dioxide with bicycloalkanes to make high-performance, recyclable polyesters. They used bicyclic butane, or BCB, and bicyclic pentane, or BCP, monomers in a direct alternating copolymerization. A simple organic catalyst initiated…

A planet 64 light-years away is sending radio signals; astronomers trace their source to auroras on the distant world |

Astronomers have reported the first direct detection of radio emission from an exoplanet, tracing the signals to the young gas giant β Pictoris b, located approximately 64 light-years from Earth. Using South Africa’s MeerKAT radio telescope, researchers identified recurring radio bursts and localised their source to the planet rather than its host star. The emission…
