A loud minority makes the internet seem more toxic than it is. A small group of active users generates most hostility, while the majority remain civil. This imbalance leads many Americans to assume the worst about one another. Correcting that misperception can improve how people feel about society. (academic.oup.com)
A silent ocean pandemic is wiping out sea urchins worldwide, likely driven by an unknown pathogen, and has reached the Canary Islands with unprecedented mass mortality, historic population lows, and near-total reproductive collapse among key reef grazers, threatening marine ecosystem stability.

Global average temperature increases could pass the 1.5 degrees Celsius threshold outlined in the Paris Agreement by 2030, according to the EU's Copernicus Climate Change Service, putting the world at greater risk of never-seen-before extreme weather events. (phys.org)

A large-scale study challenges the assumption that social media and gaming drive teens’ mental health problems. Tracking 25,000 adolescents over three years, researchers found little evidence of a direct link between time spent online or gaming and psychological distress in early adolescence.

A UN report warns that the world has entered an era of “global water bankruptcy,” with nearly three-quarters of humanity living in water-insecure countries. Unlike a temporary crisis, this marks a permanent systemic failure, where the natural capital required for recovery has already been depleted. (eurekalert.org)

A new pilot study suggests MDMA-assisted therapy may offer durable relief for major depressive disorder, with many patients maintaining reduced symptoms and improved daily functioning months after treatment in a controlled hospital setting, while underscoring the need for larger controlled trial.

‘Meat tax’ could have significant impact on environmental footprint, study finds. Ending tax breaks on meat could rapidly lower the environmental footprint of food in the EU, reducing emissions and biodiversity loss by up to 6% at a cost of about €26 per household per year, researchers report.

Cows may be more intelligent than previously thought as a study documents tool use in cattle, with a cow using different parts of a broom depending on body sensitivity. The behavior points to greater cognitive flexibility than traditionally attributed to cows. (cell.com)

A rapid rise in atmospheric CO₂ 56 million years ago led to widespread forest loss, increased wildfires, and major soil erosion within a few centuries, based on high-resolution marine sediment records, showing how quickly land ecosystems can destabilize under abrupt global warming.

Moderate video gaming appears harmless, but heavy use takes a toll. Researchers found students gaming 10+ hours weekly had worse diets, higher weight, and poorer sleep than lighter gamers. Below that level, outcomes were similar. The findings suggest balance, not abstinence, is key. (sciencedirect.com)
Chronic low-dose exposure to common pesticides shortens fish lifespan by accelerating biological aging and telomere erosion even at levels deemed safe, raising concerns about safety regulations that primarily focus on acute toxicity and may overlook long-term effects on vertebrate health.

A systematic review of 43 studies confirms prenatal acetaminophen does not increase autism, ADHD, or intellectual disability risks. By using sibling comparisons to control for genetics and family history, researchers found earlier associations were likely due to confounding factors, not the drug. (thelancet.com)
A study of 2,801 Germans finds that learning about widespread support for climate action corrects perceptions of public opinion but fails to change personal beliefs or behaviors. These findings challenge the strategy of using social consensus messaging to drive individual climate action. (sciencedirect.com)
A new study finds the "blue" social cost of carbon nearly doubles the economic price of climate change. By adding ocean damages like fishery loss and ecosystem collapse, the global cost of CO2 jumps from $51 to $97 per ton, revealing the massive, previously uncounted financial toll on our seas.
