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.

A new report says global temperatures have reached record highs as the El Niño climate pattern strengthens in the Pacific. El Niño, which warms ocean surface waters and alters weather worldwide, is adding to the underlying warming trend driven by greenhouse gas emissions. Scientists warn the combination could push average temperatures to new extremes in the coming months, with implications for heatwaves, droughts and storms across many regions.

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.

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, suggesting these massive tectonic systems may die piece by piece rather than all at once. The finding offers new insight into how subduction zones end over geological time, with implications for understanding seismic hazards in the Pacific Northwest, where the Cascadia zone poses earthquake and tsunami risks.

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.

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.

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.

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.

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 research suggests radiation exposure could trigger a hallmark of Alzheimer's disease in the brain, adding to concerns about the neurological effects of radiation from medical treatments, occupational settings or space travel. The finding points to possible mechanisms linking radiation to dementia-like changes, though scientists caution more work is needed to confirm the risk in humans.

The New York Times reports on a scientific discovery connected to an $80 motel room that researchers say could shed light on the origins of life. Details of the finding and the scientists involved remain limited, but the story highlights how an ordinary roadside room became tied to research into how life first emerged on Earth.

New research indicates that Earth microbes can survive under simulated conditions of the ocean beneath the ice of Saturn's moon Enceladus, suggesting life there is not out of the question. Scientists see the finding as encouraging for the search for life beyond Earth, since Enceladus's subsurface ocean is considered one of the most promising places to look.

Germany is creating a digital archive to preserve American climate data that researchers fear could be removed or altered under the Trump administration. The project, described as a digital Noah's Ark, would store US government climate datasets outside the United States. Scientists say safeguarding records on temperatures, emissions and extreme weather is vital for ongoing research, and the initiative reflects growing concern that federal climate information may no longer be reliably maintained.

Australian scientists have developed technology that can measure how flammable eucalypt vegetation is from space, according to ABC News. The research could give authorities a new tool for assessing bushfire risk across vast and remote forested areas, allowing more targeted preparation ahead of dangerous fire seasons in Australia.

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.

Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.

Scientists at a Colorado cold laboratory are working to better understand hail as the damage it causes continues to grow. Hail already causes billions of dollars in losses each year in the United States, and researchers warn that a warming climate could make severe hailstorms more frequent or more destructive. The reporting by Hannah Covington in High Country News highlights how little is still known about how hailstones form and grow inside storms, and why improved forecasting matters for insurers, farmers and homeowners across hail-prone regions.

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.

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.

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.

A new interactive map charting glacier extinction has been launched, tracking which of the world's glaciers are projected to disappear and when. The tool comes as scientists warn that glacier loss is accelerating worldwide, threatening water supplies for millions and raising concern among skiers, mountain communities and climate researchers.
