The Trump administration is retreating from a planned executive order that would have given the White House greater control over National Institutes of Health grant decisions. Semafor reports the proposal is now considered effectively dead after widespread pushback from scientists, universities, and lawmakers who argued it would politicise biomedical research funding. Observers are watching whether further attempts to centralise NIH grant approvals will follow.

Researchers suggest a long-standing interpretation of a 2-billion-year-old geological record may be wrong, with implications for how scientists understand Earth's ancient atmosphere and early conditions. The claim is drawing attention because such clues underpin theories about the planet's oxygenation and climate history, and a misreading could require revisions to models of how Earth's environment evolved over deep time.

Researchers report the first direct radio signal detected from a planet outside the solar system, a milestone in the search for worlds beyond our own. The detection, picked up by astronomers studying distant planetary systems, could open a new way to study exoplanets' magnetic fields and potential habitability. Scientists caution that more observations are needed to confirm the signal's origin.

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.

Researchers affiliated with Harvard University report detecting a radio signal originating directly from a planet outside our solar system. The detection would mark a rare direct radio observation of an exoplanet, potentially revealing details about its magnetic field and environment. The news is drawing wide attention online, with commenters speculating about whether the signal could have a natural origin or something more intriguing.

A new study reports that the Earth's crust is slowly tearing apart beneath the Pacific Northwest, in the Cascadia region of the United States. The finding concerns the tectonic forces acting under the area, which includes Oregon and Washington. Scientists are highlighting new details about how the plate boundary there is deforming, a topic of interest given the region's earthquake risk.

Researchers have reviewed anti-aging treatments to determine which ones actually reduce biological age rather than just promising to do so. The findings point to certain interventions that measurably changed markers of biological aging, while others failed to show real effects. The report is drawing attention as interest grows in science-backed approaches to slowing aging.

Researchers are calling on organisers of the 2034 Winter Olympics in Salt Lake City, Utah, to use the Games as a catalyst for improving the region's air quality. Utah's valleys regularly suffer from pollution-trapping inversions, and scientists argue the Olympic spotlight should be leveraged to push for lasting clean-air policies rather than short-term measures.

Researchers have developed an artificial intelligence system capable of interpreting the chemical instructions that tell embryo cells what type of cell to become. The work focuses on how chemical marks on DNA guide early development, with the AI able to read these patterns and predict cell fate. Scientists say such tools could deepen understanding of development, birth defects and regenerative medicine, though further validation will be needed.

Australian researchers have developed technology that allows scientists to measure how flammable eucalypt forests are from space, using satellite data. Eucalypts are highly fire-prone trees central to Australian bushfire risk, and the technique could improve fire danger forecasting and help authorities prepare for bushfire seasons by monitoring vegetation flammability across vast, remote landscapes without ground surveys.

President Trump pledged to reveal the truth about unidentified flying objects, drawing attention from scientists who hoped for the release of government data on aerial phenomena. Researchers say that despite the promises, concrete disclosures and verifiable evidence have yet to materialise, leaving the scientific community frustrated and still waiting for answers about unexplained sightings.

High Country News reporter Hannah Covington examines hail damage, a problem costing billions of dollars annually in the United States and one that could intensify as the climate warms. At a cold laboratory in Colorado, scientists are working to better understand how hailstones form so they can improve forecasting and reduce losses to crops, vehicles and buildings.

Saudi Aramco scientists have contributed to IPCC climate reports, the UN assessments that shape global climate policy. Reporting by the Guardian highlights how oil company researchers ended up with roles in the world's most influential climate science documents, raising questions about conflicts of interest and industry influence over the scientific consensus on fossil fuels and global warming.

Researchers have deliberately destroyed or burned fragments of ancient scrolls as part of an effort to unlock a mystery roughly 2,000 years old. The unusual decision highlights the tension between preserving rare artifacts and using destructive techniques to extract their hidden contents. Details of what the scrolls revealed and which collection they belonged to have not yet been fully reported.

Scientists are reported to be working on bringing back the woolly mammoth, with artificial intelligence playing a role in the de-extinction effort. The claim, reported by the New York Post, suggests AI tools are being used to advance research into resurrecting the extinct species. The project would mark a major step in genetic engineering and conservation science if successful.

Researchers report the discovery of a microorganism nicknamed the "fire amoeba" that survives at temperatures far beyond what was thought possible for life. The finding challenges established assumptions about the upper heat limit for living cells and could reshape understanding of where life can exist, including in extreme environments on Earth and potentially elsewhere. Coverage is highlighting how the organism survives conditions that would destroy most known biology.

Scientists report identifying a stress-triggered molecular switch that appears to drive depression. The finding points to a specific biological mechanism that could explain how chronic stress translates into depressive symptoms, and may open new avenues for targeted treatments. Details of the research, including which molecule is involved and how it was demonstrated, remain limited in the available reporting.

Scientists say America's fall foliage is shifting, with peak leaf-peeping colors arriving later and displays becoming less vibrant in some regions. Warmer temperatures and changing weather patterns are cited as key drivers affecting when and how leaves turn across the country. Coverage highlights what this means for tourism and the future of autumn landscapes.

Researchers have reported a key early-universe measurement determined with record-breaking precision. The result refines scientists' understanding of conditions shortly after the Big Bang, though details of which quantity was measured and by which team were not provided. Such precision advances are closely watched in physics because they can confirm the standard cosmological model or expose gaps where new physics might be hiding.

New research indicates that Earth microbes can survive under simulated conditions of the ocean beneath the ice of Saturn's moon Enceladus, suggesting life there is not out of the question. Scientists see the finding as encouraging for the search for life beyond Earth, since Enceladus's subsurface ocean is considered one of the most promising places to look.

NASA's Perseverance rover has found evidence that Jezero Crater on Mars was more than just an ancient lake, according to new findings reported by Mashable. The discovery suggests the crater experienced a more complex geological and watery history than scientists previously believed, adding to the growing picture of Mars as a planet that once hosted diverse wet environments.

Brazil's CNPEM research centre is collaborating with CERN on superconducting magnet technology for a proposed 91km particle collider. The partnership would connect Brazilian scientists to the world's leading high-energy physics laboratory as CERN develops advanced magnets for a future circular collider larger than the LHC.
