Connected boards echo climate rules, yet many firms move pollution instead

Connected boards echo climate rules, yet many firms move pollution instead Lisa Lock Scientific Editor Andrew Zinin Lead Editor The good news: When environmental rules pressure one company, the effect can spread through shared boardroom ties, leading connected firms to reduce emissions, too. The bad news: The positive impact on the climate is limited, as these firms often shift polluting activities elsewhere, research from Radboud University and Stockholm University shows.

Real-time fish interaction enlarges young guppy brains, while screen time falls short

Real-time fish interaction enlarges young guppy brains, while screen time falls short Sadie Harley Scientific Editor Robert Egan Associate Editor Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. The findings suggest that live social interaction in real time may be important for brain development.

Deployed trusted-node quantum key distribution over 300 km with a multi-core fiber access link

Announce Type: cross Abstract: Quantum key distribution (QKD) is increasingly considered for deployment in realistic communication networks, where long distances, heterogeneous fiber infrastructure, and coexistence with classical traffic present substantial challenges. Here, we demonstrate trusted-node QKD between Link\"oping University and the Stockholm hub of the Swedish national quantum communication infrastructure over 270 km of deployed single-mode fiber, extended by a 33 km multi-core...

This new diabetes pill burns fat without the downsides of Ozempic

This new diabetes pill burns fat without the downsides of Ozempic - Date: - June 3, 2026 - Source: - Karolinska Institutet - Summary: - Scientists have developed an experimental diabetes and obesity pill that works in a completely different way from drugs like Ozempic. Rather than reducing hunger, it activates metabolism in skeletal muscle, helping lower blood sugar and increase fat burning while preserving muscle mass. Early clinical results suggest the treatment is safe and well tolerated.

Ancient cave lion genomes reveal a distinct lineage

Ancient cave lion genomes reveal a distinct lineage Sadie Harley Scientific Editor Robert Egan Associate Editor A new study on multiple genomes from the extinct cave lion has discovered that it represented a highly distinct evolutionary lineage, which separated from modern lions more than a million years ago. The results also show that the cave lion had a history of interbreeding with modern lions that was tightly linked to past climatic changes. These findings are published in the journal...

First human SMUG1 atomic snapshots reveal how cells repair DNA

First human SMUG1 atomic snapshots reveal how cells repair DNA Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers have captured the first atomic structures of human SMUG1, an enzyme that helps cells repair damaged DNA. The findings provide new insight into how cells recognize and remove harmful DNA bases, and may support future efforts to develop drugs that target this DNA repair pathway. "These structures give us the first detailed view of how human SMUG1 engages...

Stupid hot: Heat waves cause cognitive changes in animals, making them more aggressive and unable to complete basic tasks

Stupid hot: Heat waves cause cognitive changes in animals, making them more aggressive and unable to complete basic tasks As temperatures rise, some creatures pick fights while others struggle to learn. The consequences of these behavioral changes may ripple through ecosystems. On a blazing hot day in South Africa, female southern pied babblers can't think straight.

Genome study shows what made the extinct Ice Age cave lion unique

Genome study shows what made the extinct Ice Age cave lion unique June 4 : The cave lion was one of the biggest cats to ever live, prowling a huge swathe of territory from Western Europe across Siberia and into North America and hunting large prey - and perhaps even people - before going extinct around the end of the Ice Age. New genome research reveals what made this big cat unique and how it differed from the modern lion, its smaller cousin, though the two species did sporadically...

They call it 'stupid hot' for a reason: Heat muddles animal brains

They call it 'stupid hot' for a reason: Heat muddles animal brains Gaby Clark Scientific Editor Andrew Zinin Lead Editor On a blazing hot day in South Africa, female southern pied babblers can't think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic.
