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.

The Trump administration is retreating from a proposed executive order that would have given the White House greater control over National Institutes of Health grant decisions. Reporting by Semafor says the plan, which would have tightened political oversight of NIH research funding, is now considered 'dead' after significant pushback from scientists, universities and lawmakers. The retreat comes amid ongoing concerns over federal science funding policy.

Scientists have developed the most accurate atomic clock ever built, according to a newly published report. The clock advances precision timekeeping, which underpins GPS navigation, telecommunications and tests of fundamental physics. Researchers say such devices lose tiny fractions of a second over billions of years, pushing the limits of measurement science and potentially prompting a redefinition of the second itself.

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.

An NPR report says AI assessors conclude that current science cannot yet support the safety measures the public wants from artificial intelligence. The finding highlights a gap between expectations for AI safeguards and what research can actually verify, renewing debate among scientists and policymakers over how to regulate systems whose risks remain poorly understood.

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 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.

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.

NASA scientists are mapping vast hidden valleys buried beneath Greenland's ice sheet, using radar and other remote-sensing techniques to reveal the dramatic landscape below. The work helps researchers understand how meltwater drains under the ice and how this may influence ice sheet behaviour and sea-level rise. The findings highlight how much of Greenland's geography remains unseen beneath kilometres of ice.

Researchers report observing a deadly brain cancer physically remodel brain tissue as the tumor grows. The findings offer a rare real-time view of how glioblastoma-type cancers distort and reorganize the brain, potentially improving understanding of disease progression and treatment approaches.

New research suggests the gravitational pull of the Sun and Moon, which drives tides in the Earth's crust, may help trigger earthquakes. Scientists believe they have identified the mechanism by which these small tidal stresses can nudge faults already close to slipping, potentially explaining why some quakes occur at particular tidal phases.

Researchers report that reshaping light allows them to control magnetic memory and directly influence a material's magnetic properties. The work points to a new way of writing and manipulating magnetic data using light rather than conventional magnetic fields, a step that could matter for future data storage technologies. Details of the research team, institution and peer-reviewed publication have not been made available in the coverage, so the scope and significance of the finding remain hard to assess.

Researchers subjected water to light roughly 10 billion times more intense than sunlight, expecting evaporation to speed up dramatically. Instead, the water's evaporation rate barely changed, defying the straightforward expectation that more light energy means faster evaporation. The surprising result has drawn attention in physics circles, raising questions about how energy moves through water at extreme intensities and what invisible processes may be limiting evaporation.

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.

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.

KESQ's Weather Insider segment examines the satellites used to study the world's oceans and monitor El Niño conditions. The piece explains how space-based observation of sea surface temperatures and ocean patterns helps forecasters understand and predict El Niño's effects on global weather. It highlights the role of satellite technology in improving weather and climate forecasting.

Hail is costing the United States billions of dollars a year in damage to roofs, crops, cars and infrastructure, and scientists warn the problem could intensify as climate change alters storm patterns. Hailstorms are among the costliest weather events, and insurers and homeowners are increasingly exposed. Discussion centres on why hailstorms may be growing more destructive and how communities can prepare.

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 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.

Researchers have examined Bionic Reading, a technique that bolds the first letters of words to guide the eye, to see whether it genuinely helps people read faster. The scientific test found little support for the claimed speed benefit, prompting discussion about whether the popular formatting tool is more hype than help.
