New data indicates the current El Niño is the strongest ever measured, marking a major shift in global weather patterns. The development is drawing attention because a powerful El Niño typically brings droughts, floods and heat extremes to different regions worldwide, with scientists watching closely for effects on temperatures, agriculture and extreme weather in the months ahead.

Scientists are developing new methods to control mosquitoes, the animal that kills more people than any other on Earth. As the climate warms, mosquito seasons are growing longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Reports highlight how shifting temperatures are expanding the disease threat into new regions and prompting fresh research into targeting the insects.

New research from the University of Arizona analysing decades of satellite imagery finds that the world's drylands, though greening as vegetation responds to rising carbon dioxide, are increasingly locked into extreme 'boom-and-bust' cycles — rapid plant growth followed by sudden collapses. Scientists warn the pattern could destabilise ecosystems and the communities that depend on them.

New findings indicate Mercury is contracting more quickly than previous estimates suggested. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to wrinkle and crack. The updated measurements challenge existing models of how the planet's interior cools, prompting discussion among planetary scientists about what this reveals about Mercury's geological evolution.

Scientists report identifying a previously unknown brain circuit that could explain why heart attacks often worsen after the initial event. The finding suggests the brain may trigger processes that compound damage to the heart in the hours and days following an attack. If confirmed, the discovery could open new avenues for treating patients after a heart attack and reducing long-term harm.

Anthropic claims its Claude AI helped identify a previously unknown gene-editing enzyme, a result that could matter for biotechnology if it holds up. The company itself cautions the finding has not yet been experimentally verified or peer-reviewed, and scientists are urging independent confirmation before drawing conclusions.

Scientists report that the Earth's crust beneath Italy is 'unzipping,' a process they say is driving seismic activity along the Apennine mountain range. The finding offers a new explanation for the earthquakes that regularly strike the Italian peninsula and is drawing attention for its striking description of how the crust is gradually pulling apart.

Osprey numbers are falling along the US East Coast, and scientists believe they have identified the reason behind the decline. The Washington Post reports on new findings explaining why the fish-eating raptors, once a celebrated conservation success story in the region, are now struggling. The research has drawn attention from readers concerned about the health of coastal ecosystems.

A new report describes geological rifting underway beneath the Pacific Northwest, where tectonic forces are slowly pulling the Earth's crust apart. The findings are drawing widespread attention, with readers sharing and discussing the story of the region's underlying seismic activity. Scientists point to the ongoing deformation of the Cascadia region as evidence of powerful forces reshaping the ocean floor and coastline over geological timescales.

A new study is probing whether artificial intelligence systems can experience pain or suffering, adding to a growing body of research on machine sentience and AI welfare. The findings have sparked debate among scientists and commentators about how to test subjective experience in machines and what ethical obligations, if any, would follow if AI systems could feel.

PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

Scientists studied 22,000 hours of bear footage and published findings on bear behavior, according to The Washington Post. The large-scale video analysis offers researchers a new way to observe how bears act in the wild without disturbing them, and the unusual methodology is drawing wide attention.

A new report suggests scientists may have misinterpreted evidence dating back some two billion years, with potential implications for how Earth's early history is understood. The finding is drawing attention in science media, as re-evaluating such ancient clues could reshape assumptions about the planet's past conditions and evolution.

Bulgarian National Radio reports that night-time temperatures in Bulgaria have risen sharply over the past two decades. The finding points to warming that is most visible after dark, a pattern scientists link to climate change because it reduces nighttime cooling and puts additional strain on health, agriculture and energy use. The report is drawing attention as heat records continue to fall across the region.
