New data indicates the current El Niño is the strongest ever measured, marking a major shift in global weather patterns. The warming of the Pacific is expected to bring droughts, floods and temperature extremes across many regions, and scientists are watching closely for impacts on agriculture, water supplies and extreme weather in the months ahead.

Scientists are developing new ways 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 extended warm periods are expanding the threat to new regions and prompting research into novel control methods.

Scientists are tracking a slow-moving, planetary-scale Kelvin wave in the Pacific that is heading toward the California coast. The ocean phenomenon could raise sea levels along the coast by up to a foot, with El Niño conditions keeping warm water trapped near the shoreline. Observers are watching for increased coastal flooding and erosion risks as the wave arrives.

Pope Leo has stated that concerns about the risks of artificial intelligence are legitimate and should not be dismissed as fake news. His remarks add a prominent moral voice to the global debate over AI safety, reinforcing calls from scientists and regulators who warn the technology needs careful oversight as it spreads through society.

Ultra-processed foods are at the center of an ongoing battle over nutrition policy and public health guidance. Debate continues over how strongly these products should be regulated or warned against, with scientists, food companies and policymakers weighing the evidence on their health effects. The discussion remains active as health authorities consider how to address processed food consumption.

New coverage from Phys.org and the Natural History Museum warns that shifting climate conditions could change the risks posed by deadly rodent-borne diseases. Warmer temperatures and altered rainfall patterns may expand rodent habitats and increase human contact with pathogens such as hantavirus and Lassa fever, prompting calls for improved disease surveillance as environments change.

A new Wired report describes research suggesting certain pancreatic cells are only a single genetic modification away from becoming insulin-producing cells, a potential route to treating diabetes. Scientists say the finding could open new regenerative approaches, though the work remains at an early stage and clinical applications are likely years away.

China has introduced 15-year research grants aimed at attracting the world's brightest young scientists, according to the South China Morning Post. The long-term funding scheme signals an effort to draw top international research talent to Chinese institutions and strengthen the country's standing in global science and innovation.

Anthropic is reported to have achieved a significant breakthrough in biology, prompting CNET to ask independent scientists to evaluate the claim. Researchers are being asked to assess whether the AI company's reported result represents a genuine advance or an overstatement. The story is fueling debate about how far AI labs' science claims should be trusted and how experts judge them.

The New York Times reports on claims that Anthropic's artificial intelligence independently produced a scientific finding, reportedly in biology involving an enzyme, with work credited to a researcher named Mestre. The article examines whether the system genuinely made a discovery on its own or whether human scientists played the decisive role. Readers are debating how much credit autonomous A.I. systems can fairly claim for genuine scientific breakthroughs.

Researchers with the Max Planck Society and partners are tracking how the war in Ukraine has affected Ukrainian academics, documenting displacement, disrupted careers and the breakdown of free scholarly mobility during armed conflict. The work highlights how scientists' international movement and collaboration collapse under war, raising questions about how the global research community can support scholars in conflict zones.

Roughly 85% of the matter in the universe has never been directly detected, as it does not interact with standard scientific instruments. UCLA astrophysicist Alvine Kamaha and the LUX-ZEPLIN collaboration are working to change that, operating a detector nearly 1.6 kilometres underground in South Dakota to catch rare particle interactions from dark matter.

Scientists and fishermen in the United States are calling on federal agencies to maintain funding for a deep-ocean observation system. The network provides data on ocean conditions that researchers use for study and fishing fleets rely on for safety and operations. Both groups warn that losing the funding would leave a gap in monitoring of deep-sea environments and could affect commercial fishing decisions.

A Kelvin wave is a pulse of unusually warm water that travels eastward along the equatorial Pacific, pushing warmer water toward the Americas. Scientists are tracking current Kelvin wave activity because a strong pulse reaching the West Coast could raise ocean temperatures near California and influence weather patterns, potentially adding to signs of El Niño conditions developing.

Anthropic is facing pushback over a claimed biology breakthrough made using its Claude AI system, after a scientist said he had already achieved the same result. The dispute raises questions over whether the AI truly produced something novel or merely rediscovered existing work, a recurring issue in AI-assisted scientific claims.

New research shows that Earth microbes can survive conditions simulating the ocean beneath the ice of Enceladus, Saturn's icy moon. Scientists exposed microorganisms to the cold, salty, high-pressure environment expected there, and some endured. The finding suggests life as we know it could plausibly exist in the moon's subsurface sea, strengthening the case for future missions to sample plumes of water erupting from Enceladus.

New research reported by The Scientist suggests bacteria can learn and store memories in ways that resemble artificial neural networks. The findings point to memory-like behaviour in single-celled organisms without nervous systems, drawing comparisons between microbial adaptation and machine learning models. Scientists say the work could reshape understanding of how simple life forms process information and inspire new computing approaches.

MIT Technology Review examines the question of when an AI system can truly be credited with making a scientific discovery. As AI tools increasingly generate hypotheses, run experiments and produce research results, scientists and philosophers are debating what threshold of autonomy and understanding would justify calling a discovery AI's own rather than that of its human collaborators.
