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.

Deep sea landscapes are a new frontier of human exploration—here's what we may find‎

When we dream of landscapes, we might imagine rolling valleys or rugged mountains. But there is a whole landscape hidden from human view: the secret world of the seafloor.

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.

Nuclear speckles play a key role in the progression of viral infection, research reveals‎

Herpes simplex virus type 1 (HSV-1) infection dramatically remodels the host cell's nuclear structures. Infection leads to the formation of viral replication compartments and to chromatin marginalization to the nuclear periphery. Joint research by the Universities of Jyväskylä (Finland) and Bar-Ilan (Israel) reveals that viral infection also alters the structure of nuclear speckles, which are essential for messenger RNA processing.

Sunray-like ripples emerge on a frozen reaction front‎

Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review Letters, Anne De Wit and colleagues at the Université Libre de Bruxelles have shed new light on the patterns that emerge in reaction–diffusion systems, offering fresh insight into how similar structures arise in the natural world.
