How AI‑powered policing is endangering the public's trust in police‎

Since the release of ChatGPT in 2022, artificial intelligence (AI) has dominated the cultural landscape. Uptake across various sectors, including law enforcement, quickly followed, usually with minimal foresight and little to no guardrails, like effective policies or laws, to govern AI use.

Climate policy could learn from people who already live within the limits of sufficiency‎

Tina Nyfors, who recently defended her doctoral thesis at the University of Helsinki, studied sufficiency, a way of living and a principle for organizing society to stay within environmental limits while ensuring that people have enough. Nyfors directs attention to people whose carbon footprint is already in line with sufficiency and refers to them as the sufficiency class. Their way of life has a moderate climate impact yet still meets their needs.

The discovery of the Great Barrier Reef's whale maternity ward‎

It started with a simple message: "This is the year to do something small for something huge." Now, 17 years later, the Whitsundays region has some of the best protection in the world for migrating humpback whales.

Galápagos corals show El Niño events are more extreme now than in past 1,000 years‎

Temperatures have warmed dramatically across the equatorial Pacific Ocean in 2026, signaling the onset of a strong and potentially historic El Niño. These events can affect weather around the world, and the intensity of recent El Niño events is raising alarm that, as global temperatures rise, they are becoming stronger and more destructive.

Earlier swathing opens a new pathway for subterranean clover seed harvest‎

Subterranean clover's ability to bury its seed supports pasture persistence but makes commercial seed harvesting difficult. The industry relies on aging Horwood-Bagshaw (HB) suction harvesters, which collect seed from fully dry crops after repeated tillage and raking.

Diverse portfolio of protected areas key to Mexican conservation efforts‎

In 2020, Mexico joined 150 nations committing to protect 30% of its territory by 2030 as part of the global 30x30 initiative. More than halfway through the decade, there is ongoing debate about how to effectively expand protected areas to meet that ambitious goal.

Low temperature graphene growth opens a route to sustainable resource recycling‎

Graphene is an exceptionally useful material for creating batteries, catalysts and electronic devices. Yet producing graphene typically requires temperatures as high as 900°C (1,652°F), limiting energy efficiency and making structural control difficult. To make graphene production more practical, a recent study has overcome this long-standing temperature barrier.

Dog-friendly dining isn't just a trend, it's good for business, new research shows‎

Restaurants that go beyond simply allowing dogs on patios by offering dedicated menu items for them can significantly boost customer traffic, spending and word-of-mouth, according to new research from Toronto Metropolitan University.

Fast fashion's carbon footprint can be reduced across its life cycle, new study suggests‎

Fast fashion is built on cheap, short-lived garments, especially cotton and polyester T-shirts. To sustain its profits, the industry relies on high production frequency, short product lifespan and a globalized supply chain. All these elements contribute to making the industry a major source of global pollution.

Scientists capture first molecular-level images of water reorganization during a reaction crucial for life‎

Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion yet remain difficult to observe.
