New research indicates Mercury is contracting more quickly than previously estimated. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to buckle and form cliffs and ridges. The revised findings suggest this process is still active and accelerating relative to earlier models, prompting scientists to rethink how rocky planets cool over time.

Scientists are working near the mouth of the Mississippi River in Louisiana on what is described as a massive effort to predict the region's future. The research focuses on forecasting environmental changes along the river's delta, an area central to concerns about land loss and coastal resilience. Local coverage highlights the scale and ambition of the scientific undertaking.

A New York Times report examines whether Anthropic's artificial intelligence genuinely produced an autonomous scientific discovery, in a case involving biology and enzyme research credited to a scientist named Mestre. The question of what counts as a real AI-driven discovery — versus human-guided work marketed as machine achievement — is drawing scrutiny as labs race to claim scientific firsts for their models.

A new report suggests scientists may have misinterpreted evidence dating back some two billion years, with potential implications for how Earth's early history is understood. The finding is drawing attention in science media, as re-evaluating such ancient clues could reshape assumptions about the planet's past conditions and evolution.

Scientists report identifying a previously unknown brain circuit that could explain why heart attacks often worsen after the initial event. The finding suggests the brain may trigger processes that compound damage to the heart in the hours and days following an attack. If confirmed, the discovery could open new avenues for treating patients after a heart attack and reducing long-term harm.

A new examination of chronic traumatic encephalopathy reviews what research has established about the brain disease linked to repeated head impacts, and where scientific certainty ends. The piece weighs confirmed findings against open questions about diagnosis, prevalence and long-term effects, reflecting ongoing debate among scientists, athletes and sports organisations over how much is truly known.

The New York Times reports on a scientific discovery connected to an $80 motel room that researchers say could shed light on the origins of life. Details of the finding and the scientists involved remain limited, but the story highlights how an ordinary roadside room became tied to research into how life first emerged on Earth.

New research indicates Earth microbes can survive in conditions mimicking the ocean of Enceladus, Saturn's icy moon. The findings strengthen the case that Enceladus could potentially host life, since its subsurface ocean is a leading target in the search for life beyond Earth. Scientists say the experiment shows known microorganisms are more hardy than assumed under such extreme environments.

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.

Scientists say one of Saturn's ice-covered moons could be capable of hosting alien life. The claim, reported by BBC Sky at Night Magazine, points to conditions beneath the moon's frozen surface that may be suitable for living organisms. The finding adds to growing interest in icy moons as potential habitats beyond Earth, though no life has actually been detected.

Australian scientists have developed technology that can measure how flammable eucalypt vegetation is from space, according to ABC News. The research could give authorities a new tool for assessing bushfire risk across vast and remote forested areas, allowing more targeted preparation ahead of dangerous fire seasons in Australia.

Scientists report that the Earth's crust beneath Italy is 'unzipping,' a process they say is driving seismic activity along the Apennine mountain range. The finding offers a new explanation for the earthquakes that regularly strike the Italian peninsula and is drawing attention for its striking description of how the crust is gradually pulling apart.

Anthropic says its Claude AI helped identify a previously unknown gene-editing enzyme, a claim that would be notable if verified. The company itself acknowledges the finding has not been independently confirmed or validated through peer review, so scientists are treating the announcement with caution until laboratory evidence backs it up.

Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.

Scientists at a Colorado cold laboratory are working to better understand hail as the damage it causes continues to grow. Hail already causes billions of dollars in losses each year in the United States, and researchers warn that a warming climate could make severe hailstorms more frequent or more destructive. The reporting by Hannah Covington in High Country News highlights how little is still known about how hailstones form and grow inside storms, and why improved forecasting matters for insurers, farmers and homeowners across hail-prone regions.

New research indicates that the gravitational pull of the Sun and Moon can trigger earthquakes, and scientists may have identified the mechanism behind it. The findings suggest tidal stresses on faults could set off quakes that are already primed to rupture, a long-debated idea in seismology.

The New York Times has published a retrospective examining how scientists took on existential risk in an earlier era, recalling a moment when researchers warned the public they intended to frighten them about a technology capable of destroying civilization. The piece draws on that historical episode of expert-led warning, a story resonating now as scientists again debate humanity-scale dangers from new technologies, including artificial intelligence.

Researchers at the New York Botanical Garden have published a series of papers in the journal Plants, People, Planet arguing that growing threats to plant diversity are narrowing the options for building healthier, more resilient food systems.
