Globe-trotting ancient 'sea-salamander' fossils rediscovered from Australia's dawn of the Age of Dinosaurs‎

Around 250 million years ago, what is today scorching desert in remote northwestern Australia was the shore of a shallow bay bordering a vast prehistoric ocean. Fossils recovered from this region over 60 years ago, and almost forgotten in museum collections, have now shed new light on the earliest global radiations of land-living animals adapting to life in the sea.

Study finds warming world increases days when weather is prone to fires around the globe‎

The number of days when the weather gets hot, dry and windy—ideal to spark extreme wildfires—has nearly tripled in the past 45 years across the globe, with the trend increasing even higher in the Americas, a new study shows.

Elevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill‎

Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results from the University of Maryland School of Public Health continue to show high levels of E. coli and S. aureus — commonly called staph, including antibiotic-resistant MRSA.

How shaming unethical brands makes companies improve their behavior‎

Recent investigations have uncovered forced labor in agricultural supply chains, illegal fishing feeding supermarket freezers, deforestation embedded in everyday food products, and unsafe conditions in factories producing "sustainable" fashion. These harms were not visible on labels. They surfaced only when journalists, whistleblowers or activists exposed them.

The algorithmic feed on X could be shifting political views toward conservatism‎

Turning on the "For You" algorithm on X (formerly Twitter) may shift users' political opinions toward more conservative views, suggests research involving nearly 5,000 X users. These effects are shown to persist even after users return to a chronological feed, according to a new paper published in Nature.

Why your brain has to work harder in an open-plan office than private offices‎

Since the pandemic, offices around the world have quietly shrunk. Many organizations don't need as much floor space or as many desks, given many staff now do a mix of hybrid work from home and the office. But on days when more staff are required to be in, office spaces can feel noticeably busier and noisier. Despite so much focus on getting workers back into offices, there has been far less focus on the impacts of returning to open-plan workspaces.

How to improve the performance of qubits: Super-fast fluctuation detection achieved‎

Using commercially available technology and innovative methods, researchers at NBI have pushed the limits of how fast you can detect changes in the sensitive quantum states in the qubit. Their work allows researchers to follow rapid changes in qubit performance that were previously invisible. The study is published in the journal Physical Review X.

National survey finds microplastic pollution around Britain's coastline could be double than previously recorded‎

Data collected during a rowing challenge around the seas of Great Britain has found significantly higher concentrations of microplastic pollution than previously recorded, a new report finds. The team, which included University of Surrey academic Hannah Davies, rowed more than 2,000 miles in just 50 days as part of the GB Row Challenge 2024, while also collecting crucial data on microplastic pollution, underwater man-made sound, water temperature, salinity and biodiversity.
