New data indicates the current El Niño is the strongest ever recorded, driving a major shift in global weather patterns. The development is expected to bring hotter temperatures, droughts and flooding to many regions, and scientists are watching closely for knock-on effects on agriculture, storms and global climate over the coming months.

Scientists are developing new ways to control mosquitoes as warmer temperatures lengthen mosquito seasons and expand the range of dangerous diseases like malaria and dengue. The mosquito kills more people than any other animal on earth, and researchers warn that longer warm periods give the insects more time to spread illness, prompting renewed efforts in prevention and control.

NASA's Perseverance rover has uncovered evidence that Jezero Crater on Mars was more complex than previously thought, indicating it was not simply an ancient lake. The finding suggests the crater experienced a richer and more varied geological history, with implications for understanding Mars' past water activity and its potential to have once supported life.

A new study examines whether artificial intelligence systems could experience pain, weighing how current models respond to harmful or distressing stimuli against what scientists know about consciousness. Researchers say the question remains open, with no clear evidence that today's AI suffers, but growing attention to machine welfare as systems become more advanced.

A New York Times report examines whether Anthropic's artificial intelligence genuinely produced an autonomous scientific discovery, in a case involving biology and enzyme research credited to a scientist named Mestre. The question of what counts as a real AI-driven discovery — versus human-guided work marketed as machine achievement — is drawing scrutiny as labs race to claim scientific firsts for their models.

New research indicates Earth microbes can survive in conditions mimicking the ocean of Enceladus, Saturn's icy moon. The findings strengthen the case that Enceladus could potentially host life, since its subsurface ocean is a leading target in the search for life beyond Earth. Scientists say the experiment shows known microorganisms are more hardy than assumed under such extreme environments.

Scientists are working near the mouth of the Mississippi River in Louisiana on what is described as a massive effort to predict the region's future. The research focuses on forecasting environmental changes along the river's delta, an area central to concerns about land loss and coastal resilience. Local coverage highlights the scale and ambition of the scientific undertaking.

A new examination of evolutionary biology asks whether animals and plants can adapt quickly enough to keep pace with rapidly warming temperatures and shifting habitats. The piece highlights the mismatch between the slow pace of genetic adaptation and the speed of current climate change, raising concerns that many species may be unable to evolve in time to survive.

A new examination of chronic traumatic encephalopathy reviews what research has established about the brain disease linked to repeated head impacts, and where scientific certainty ends. The piece weighs confirmed findings against open questions about diagnosis, prevalence and long-term effects, reflecting ongoing debate among scientists, athletes and sports organisations over how much is truly known.

New research indicates that the gravitational pull of the Sun and Moon can trigger earthquakes, and scientists may have identified the mechanism behind it. The findings suggest tidal stresses on faults could set off quakes that are already primed to rupture, a long-debated idea in seismology.

A new account of the Solar System's origins says the first planetary bodies formed in molten, fire-like conditions rather than from ice and cold material, as long assumed. The claim challenges the standard picture of early planet formation, in which icy building blocks beyond the frost line were thought to dominate. Details of the research and the reasoning behind it remain limited, and reactions from other scientists are not yet clear.

A new study questions the widely held idea that climate change is driving a boom in global squid populations. Researchers challenge assumptions that warming oceans and changing conditions have fueled squid expansion, suggesting the picture is more complicated than previously thought. The findings are prompting discussion among marine scientists about how climate shifts truly affect squid stocks and the fisheries that depend on them.

New research indicates Mercury is contracting more quickly than previously estimated. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to buckle and form cliffs and ridges. The revised findings suggest this process is still active and accelerating relative to earlier models, prompting scientists to rethink how rocky planets cool over time.

Scientists have resolved a long-standing mystery concerning stick insects, according to a new report. The finding, covered by science news outlet SciTechDaily, brings closure to a biological puzzle that researchers have pursued for decades, though details of the discovery and its implications have not yet been widely reported.

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.

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 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.

Anthropic says its Claude AI helped identify a previously unknown gene-editing enzyme, a claim that would be notable if verified. The company itself acknowledges the finding has not been independently confirmed or validated through peer review, so scientists are treating the announcement with caution until laboratory evidence backs it up.

Researchers at the New York Botanical Garden have published a series of papers in the journal Plants, People, Planet arguing that growing threats to plant diversity are narrowing the options for building healthier, more resilient food systems. The papers explain why food plant diversity matters and set out a vision for collaboration between scientists, growers and communities to protect it. The warning highlights how the loss of crop varieties and wild relatives could undermine global food security.

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 California-based scientist has emerged as a possible suspect in the Tylenol murders, the unsolved 1982 Chicago-area poisonings that killed seven people and triggered a nationwide panic and major changes to product packaging. The identification renews attention on one of America's most notorious cold cases more than four decades later.

Scientists report the discovery of a gene variant dating back roughly 47,000 years that may influence muscle development in modern humans. The finding suggests an ancient genetic inheritance could partly shape muscle traits today, and researchers describe themselves as surprised by the results, sparking wide interest in human evolutionary biology.

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.
