Scientists report that as the Pacific Ocean warms, a strange reversal is taking place in its water circulation: younger surface water appears to be ageing while older deep water is becoming younger, a shift in how water masses mix and move. Researchers say the trend could signal wider changes in ocean circulation driven by warming, with possible implications for heat and carbon storage in the Pacific.

New research reported by Science News suggests that magnetic fields may have played a key role in the formation of the solar system, potentially helping to trigger the collapse of the gas cloud that gave rise to the Sun and planets. The finding could reshape how scientists understand the earliest moments of our cosmic neighbourhood.

The National Institutes of Health has launched Linked Discoveries, an experimental new PubMed tool aimed at strengthening research replication and reproducibility. The announcement is being shared in science and technology circles, with observers noting it as a step toward making published research easier to verify and build upon.

Researchers have identified a crown-shaped ring made of sulfur atoms inside mammalian cells, according to a report by Chemical & Engineering News. The discovery sheds new light on sulfur chemistry in living organisms, a field where such cyclic structures were not previously known to exist in biological systems, and may open new avenues of study.

A Norwegian science news report describes a study finding that children and teenagers aged 9 to 18 increasingly turn to AI assistants instead of Google for information and answers. Researchers say the shift is happening fast, but the effects on how young people learn, judge sources and handle misinformation are not yet known, prompting calls for closer attention from educators and parents.

Most health professionals believe key plant foods are underrepresented in official dietary guidelines, according to a report covered by Plant Based News. The finding suggests that many practitioners see current recommendations as lagging behind evidence on the health benefits of plant-based eating, and are calling for fruits, vegetables, legumes and other plant foods to feature more prominently in public dietary advice.

Researchers report that artificial intelligence can distinguish between aged and young stem cells, a finding highlighted in a new science news release. If confirmed, the method could help scientists understand how ageing affects regenerative capacity and support therapies that rely on healthy stem cells. Details of the study team and the underlying research remain limited in the available information.

Scientific American's latest science roundup covers the rising energy demands of artificial intelligence, ongoing efforts to detect subatomic particles, and research into an amoeba that thrives at extreme temperatures. The episode ties together the environmental cost of the AI boom with fundamental physics and biology discoveries, offering a snapshot of current conversations across science news.

Scientists report new findings on how tidal forces from the Sun and Moon can trigger earthquakes. The research reportedly explains the mechanism by which gravitational stresses from these celestial bodies may nudge faults already under strain, setting off quakes. The claim has drawn attention as a potential step forward in understanding earthquake timing.

Publisher Wiley has announced the launch of two new peer-reviewed research journals, Advanced Medicine and Advanced Healthy Aging, extending its existing Advanced journal portfolio. The move targets fast-growing areas of clinical and aging research, where output and funding continue to expand. The announcement was made via a science news release, with details on scope, editorial leadership and open-access terms expected from the publisher.

A new Stanford study argues that the human brain is actually two separate organs working together, challenging the long-standing view of it as a single unified structure. The finding, covered by Stanford News, is drawing attention among science readers, with commenters debating what the split means for how we understand consciousness and brain function.
