New data indicates the current El Niño is the strongest ever measured, driving a major shift in global weather patterns. Scientists say the event is altering rainfall and temperature patterns across continents, with potential impacts on droughts, floods and harvests worldwide. The finding is drawing wide attention as meteorologists track how the intensified pattern will affect weather in the months ahead.

Scientists are developing new ways to control mosquitoes as warming temperatures lengthen mosquito seasons and expand the range of dangerous diseases. Mosquitoes kill more people than any other animal on earth, and researchers warn that longer warm periods give the insects more time to spread illnesses such as malaria and dengue, prompting renewed focus on innovative control strategies.

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.

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.

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.

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.

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.

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.

Researchers at the University of California, Riverside say one of Saturn's moons may hold clues about whether life exists beyond Earth. The work points to conditions on the moon that scientists consider promising in the search for extraterrestrial life, adding to ongoing interest in icy moons with subsurface oceans as targets for future exploration.

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.

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.

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.

Scientists and news outlets are raising alarms about a slow-moving Kelvin wave — a vast, planetary-scale oceanic phenomenon — that is travelling toward the California coast. Such waves can shift warm water across the Pacific and influence coastal sea levels and weather patterns, prompting concerns about potential impacts on the US West Coast.

Scientists led by UCLA astrophysicist Alvine Kamaha, through the LUX-ZEPLIN collaboration, are searching for dark matter from a detector operating nearly a mile underground in South Dakota. Roughly 85% of all matter in the universe remains undetected by standard instruments, and the experiment tracks rare particle interactions that could reveal it. The effort is drawing attention online among space and physics enthusiasts.

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.

New research suggests a worrying association between frequent cannabis use and an increased risk of seizures. The findings, reported by Gizmodo, are drawing attention because cannabis is often assumed to be relatively safe or even beneficial for seizure disorders, and the study complicates that picture for heavy users.

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.

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.
