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 in some regions and heavy rainfall in others, with scientists warning of widespread consequences for agriculture, water supplies and extreme weather events across the globe in the months ahead.

Attention is turning to claims that the current El Niño event is unlike anything previously observed. Commentators say the warming pattern driving extreme weather worldwide is behaving in ways that set it apart from past episodes, prompting discussion about its strength and unusual characteristics. Scientists and weather watchers are debating what the record-breaking conditions could mean for global temperatures, storms and rainfall in the months ahead.

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.

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.

Anthropic is facing questions over whether its A.I. system independently produced a genuine scientific discovery. The claim, examined in a New York Times report, has prompted debate among scientists and A.I. watchers about how much credit the system deserves and whether the finding counts as discovery or as an assist to human researchers. Doubts and defenses are circulating in equal measure.

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.

New York City officials have identified another victim of the September 11, 2001 attacks using a first-of-its-kind genetic genealogy technique, marking a breakthrough in the decades-long effort to identify remains from Ground Zero. The advance offers renewed hope to families still awaiting answers nearly 24 years after the attacks, as forensic scientists continue testing thousands of unidentified fragments.

Scientists and US media are raising alarms about a slow-moving, planetary-scale Kelvin wave in the Pacific making its way toward the California coast. The ocean phenomenon could raise sea levels by up to a foot as El Niño conditions keep warm water trapped along the coastline. Observers warn the combined effect could worsen coastal erosion and flooding risks for communities already exposed to rising seas and winter storms.

Pope Leo has publicly dismissed suggestions that worries about the risks of artificial intelligence are exaggerated, saying such concerns are not 'fake news'. The remarks add the Vatican's moral weight to the global debate over AI safety, reinforcing calls from scientists and regulators for serious attention to the technology's potential harms and for safeguards in its development.

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.

NASA's Perseverance rover has uncovered evidence that Jezero Crater on Mars had a more complex history than previously thought, beyond simply being an ancient lake. The findings, reported by Mashable, suggest the crater experienced additional geological and environmental changes after the lake era, refining scientists' understanding of Mars' past habitability and water history.

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.

New reporting from researchers, including work covered by the Natural History Museum and Phys.org, suggests shifting climate conditions could change the risks humans face from deadly rodent-borne diseases. Changes in temperature and rainfall may alter rodent habitats and populations, potentially bringing infected animals into closer contact with people and expanding where diseases like hantavirus and Lassa fever pose a threat.

A Chinese deep-ocean drilling vessel has returned to port carrying core samples collected from the South China Sea, which state media and scientists have described as scientifically precious. The specimens are expected to aid research into the seabed's geology and the region's resource potential, at a time when the South China Sea remains a focal point of both scientific work and territorial disputes involving China and its neighbours.

A New York Times report examines whether Anthropic's AI system genuinely produced a novel scientific finding in biology, reportedly involving enzyme research, without human direction. The article weighs the company's claims against skepticism from scientists about what counts as a true autonomous discovery. Readers are debating where the line sits between AI-assisted research and genuine machine-led breakthroughs.

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.

A vast, slow-moving kelvin wave — an ocean phenomenon tied to the El Niño–Southern Oscillation — is reported to be heading toward the California coast, raising alarm among scientists and officials about its potential impact on weather patterns along the US West Coast. Comment is focused on what the wave could mean for extreme weather and coastal conditions in the region.

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.

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.
