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.

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.

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.

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.

Scientists and news outlets are raising alarms about a slow-moving, planetary-scale ocean phenomenon known as a Kelvin wave heading toward the California coast. Warm water trapped along the coastline by El Niño could raise local sea levels by as much as a foot, increasing coastal flooding and erosion risks. Observers are watching closely to see how the wave interacts with the ongoing El Niño pattern.

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.

Researchers have developed the most accurate atomic clock ever built, according to a report in physics news coverage. Atomic clocks underpin GPS navigation, telecommunications and tests of fundamental physics, so each improvement in precision can refine satellite positioning and allow sharper measurements of phenomena such as gravitational time dilation. Readers are discussing what the new timekeeping record means for science and everyday technology.

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.

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.

Scientists report that as the Pacific Ocean warms, its water-age structure is behaving counterintuitively: young water at the surface appears to be aging, while older deep water is getting younger, a reversal of established circulation patterns. The finding suggests climate change may be disrupting the ocean's overturning circulation, with potential consequences for heat and carbon storage. Researchers say the shift warrants closer monitoring of how the Pacific redistributes heat as global temperatures rise.

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 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.

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 Chinese deep-ocean drilling ship has returned with what state-linked reporting calls 'precious' geological samples from the South China Sea. The cores are expected to help scientists study the seabed's structure and geological history, and underscore China's growing capability in deep-sea exploration. The mission also carries strategic weight, given competing territorial claims over the disputed waterway and interest in its seabed resources.

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.
