Flooding rains, ocean gains: How a huge Murray flood gave the sea a feast

For decades, the rivers of the Murray-Darling Basin have been heavily regulated by dams and irrigation networks. As a result, the volume of water entering the ocean is about 60% smaller than 100 years ago. But nature broke through during massive floods over the summer of 2022–23,

Global rice paddy greenhouse gas emissions have doubled during the past six decades, study

Rice paddy greenhouse gas emissions have doubled during the past 60 years—but practical farm changes could cut methane emissions and support global climate targets without reducing food production, a team led by Boston College scientists reports in the journal Nature Food.

Chemically primitive galaxy from 13 billion years ago reveals record-low oxygen

An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this

Pacific plate's rotation gave Alaska's Aleutian Islands a later-life lift

New research by Brown University geologists confirms that the Aleutian Islands, the archipelago stretching from Alaska to Russia's Kamchatka Peninsula, experienced a massive geological uplift between 5 million and 7 million years ago. The researchers conclude that the uplift—a ri

Evidence identifies ancient Aboriginal mining in the Riverland

Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's Riverland. The dating formed part of the first detailed inv

Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil stor

Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships between living organisms in the past, reconstruc

Ocean warming above 1.5°C triggered year-round marine disruption across globe, study shows

Researchers at King Abdullah University of Science and Technology (KAUST) led one of the first global assessments of how marine ecosystems responded during the first year when global temperatures temporarily exceeded 1.5°C above pre-industrial levels.

Why Ho Chi Minh City's pollution sources may have been misread for years

Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution is tracked by looking at levels of levoglucosan, a chemic

Primate evolution kept aging rates stable for 25 million years despite lifespan gaps

Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
