New data shows the current El Niño is the strongest ever measured, driving a major shift in global weather patterns. The warming of Pacific Ocean surface waters is expected to bring droughts, floods and heatwaves to different regions worldwide. Scientists and news outlets are watching closely as the event intensifies, with forecasters warning of record temperatures and disruption to agriculture and weather systems into the coming months.

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.

Leading AI researchers often described as the 'godfathers' of the field have publicly warned about the risk of a runaway 'intelligence explosion', in which AI systems rapidly improve themselves beyond human control. The warning, reported by The Guardian, adds to ongoing debate among scientists and policymakers about how quickly advanced AI should be developed and regulated.

Mosquitoes kill more people than any other animal on Earth, and scientists say the threat is growing. As the climate warms, mosquito seasons are lasting longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Researchers are now exploring new methods to target and control mosquito populations before the expanding range of the insects puts more communities at risk.

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.

A UK climate minister has warned that the global food system is vulnerable to El Niño, the periodic warming of Pacific Ocean waters that disrupts weather patterns and can damage harvests. The warning, reported by New Scientist, highlights concerns that extreme weather linked to El Niño could hit crop yields and push up food prices worldwide.

Scientists in Germany are preparing to copy and store vast troves of American climate data, fearing the Trump administration could alter, restrict, or remove federal climate records. The effort has been likened to building an ark, preserving scientific information outside the United States in case it becomes unavailable at home, and has drawn attention as researchers weigh risks to publicly funded datasets.

A New York Times piece examines how scientists can influence public opinion on the risks of artificial intelligence, reportedly through protests and public engagement. It suggests researchers are becoming active voices in the debate over AI safety, rather than leaving the conversation to companies and regulators.

Negotiations on the EU's pesticides reduction law have reached a deadlock after European scientists called for a pause. EU officials face pressure to suspend talks on the Food and Feed legislation, with pushback coming both from the scientific community and from countries outside the bloc. The standoff leaves the fate of the bill uncertain.

A vast, slow-moving equatorial kelvin wave is heading toward the California coast, prompting warnings that it could strengthen El Niño conditions and raise the risk of extreme weather on the US West Coast. Scientists and commentators are watching the planetary-scale ocean warming pattern closely as concern grows over its potential coastal impacts.

Scientists and weather watchers are tracking a vast, slow-moving Kelvin wave—a planetary-scale ocean or atmospheric pattern—that is heading toward California. The development is drawing attention because such waves can influence coastal conditions and extreme weather, and concern is mounting over what impact it could bring to the US West Coast.

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.

MIT Technology Review examines the question of when an achievement can genuinely be credited to artificial intelligence as a scientific discovery rather than to the humans who built and used the system. The piece weighs criteria for attribution as AI systems increasingly generate hypotheses, run experiments and produce results in fields like biology and materials science, prompting debate among researchers over authorship, credit and the definition of discovery itself.

In an interview, political scientist Norman Finkelstein responded to Harvard's antisemitism inquiry, which found that Israeli and Jewish students "don't feel wanted at Harvard." The university said it must correct for antisemitism by embracing everyone, and Finkelstein, while voicing support for inclusivity, went on to take issue with the inquiry's framing, drawing attention and debate online.

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.

Peter Barrett, a leading figure in Antarctic science in New Zealand and internationally, has died. Colleagues describe him as a legend in the field, noting that even in death he left behind a list of tasks and challenges, reflecting his lifelong commitment to Antarctic research and climate issues. Tributes have come from across Aotearoa and the wider scientific community.

A new study is probing whether artificial intelligence systems could experience pain, one of the hardest questions in debates over machine consciousness. The research feeds into a wider argument among scientists and ethicists about whether large language models have any form of subjective experience, and what that would mean for how such systems should be treated and regulated.

President Trump pledged to reveal the truth about unidentified flying objects, drawing attention from scientists who hoped for the release of government data on aerial phenomena. Researchers say that despite the promises, concrete disclosures and verifiable evidence have yet to materialise, leaving the scientific community frustrated and still waiting for answers about unexplained sightings.

Researchers and fishermen in the United States are calling on federal agencies to maintain funding for a deep-ocean observation system that tracks conditions far below the surface. The system provides data used for fisheries management, storm forecasting and marine research, and both groups warn that losing it would leave coastal communities and scientists without critical information about changing ocean conditions.
