Researchers are presenting new imaging techniques that combine artificial intelligence with physics-based models, with applications ranging from revealing details invisible to conventional cameras to automatically coloring black-and-white anime footage. The work shows how machine learning, guided by physical principles, can reconstruct and enhance images in ways traditional methods cannot, pointing to wider uses in science and media.

An astronomer is tracking how Starlink satellites gradually sink in their orbits and using that data as a 'planetary barometer' to measure conditions in Earth's upper atmosphere. The idea is that changes in satellite orbital decay reveal atmospheric density, offering a novel scientific use for the thousands of SpaceX satellites in low Earth orbit.

Astronomers report that a dead, 'zombie' star is repeatedly flashing toward Earth because of a giant cloud of gas ejected by the star, described colourfully as a cosmic 'fart'. The wobbling object emits pulses of light at regular intervals as it rotates, and researchers are calling the new observations groundbreaking for what they reveal about the behaviour of stellar remnants.

NPR published a piece examining the search for life beyond Earth and whether scientists, institutions and the public are genuinely prepared if such a discovery were made. The article weighs current astrobiology efforts against the scientific, philosophical and practical questions that would follow a confirmed detection. Readers in science and space discussions are sharing the piece as interest in the search for extraterrestrial life continues to grow.

New research reported by ScienceDaily describes geological activity tearing apart the Earth's crust beneath the Pacific Northwest of North America. The finding concerns the Cascadia region, where tectonic forces are said to be slowly splitting the seabed and coastal crust. Geologists say the discovery sheds light on how tectonic plates deform and how the region's earthquake hazards may evolve over time.

Researchers subjected water to light roughly 10 billion times brighter than sunlight, expecting faster evaporation, but the water did not evaporate any quicker. The surprising null result challenges assumptions about how extremely intense light interacts with liquid water, and is drawing attention from physicists curious about what limits evaporation under such extreme conditions.

A strong, or 'super', El Niño event is being linked to significant regional weather impacts across the Midwestern United States. The phenomenon, driven by unusually warm Pacific Ocean waters, typically alters precipitation and temperature patterns, affecting the Midwest's agriculture, flooding risks and winter conditions. Attention is focused on how this cycle may play out differently for the region.

Measles, once close to elimination in many countries, is reappearing in outbreaks, and coverage is examining the reasons behind its return. The key factors cited in the discussion include falling vaccination rates, the extreme contagiousness of the virus, and gaps in community immunity that allow it to spread again.

Scientists have observed that the amount of dust in Earth's atmosphere has declined, reversing a previous trend. NBC News reports the shift is described as mysterious, with the cause of the reversal not yet explained. Dust in the atmosphere affects climate, air quality and weather patterns, so researchers are paying close attention to what is driving the change.

Researchers have put Bionic Reading — a format that bolds the first letters of words to guide the eye — to a scientific test, examining whether it genuinely helps people read faster.

The piece is drawing attention as researchers and readers debate how much credit AI systems deserve for scientific breakthroughs and whether the claim holds up under scrutiny.

Wired argues that the growing public backlash against data centers, driven by their strain on power grids, water supplies and local communities, has so far stopped short of a serious reckoning with their climate impact. The piece contends that debates over new data center construction focus on costs and land use while largely ignoring the carbon footprint of the AI boom that is accelerating their expansion.

New research suggests radiation exposure may trigger a key feature of Alzheimer's disease in the brain. According to ScienceAlert, the findings point to radiation potentially initiating one of the hallmark brain changes associated with the disease, adding to growing scientific interest in environmental factors that may contribute to Alzheimer's risk.

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.

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 study suggests chronic stress may cause gradual structural changes to the heart, potentially raising cardiovascular risks without obvious symptoms. Researchers point to stress hormones and prolonged strain as factors quietly reshaping heart tissue over time. The findings add to growing evidence linking mental stress with long-term heart health, prompting calls for stress management to be treated as a medical concern.

AI researcher and Coursera co-founder Andrew Ng dismissed warnings that artificial intelligence could drive humanity to extinction, describing such fears as 'science fiction'. The remarks have reignited debate between AI safety advocates, who argue catastrophic risk deserves serious attention, and pragmatists like Ng who say alarmism distracts from concrete near-term harms such as bias, job displacement and misuse.

A new study reports that a widely used dietary supplement can increase muscle strength even in people who do not exercise, according to ScienceAlert. If confirmed, the finding could have significant implications for older adults, people with limited mobility, and the fitness supplement industry.

The academy, one of the oldest natural science museums in the United States, has long been a landmark for research and exhibitions.

Researchers in Alaska say avian keratin disorder is the cause of the overgrown, fishhook-shaped beaks seen in the state's chickadee population. The condition causes abnormal keratin growth in birds' beaks and feathers, making it harder for affected birds to feed. Scientists continue to study what triggers the disorder, which has been documented among chickadees in Alaska since the 1990s.

A new DNA analysis of medieval burial sites has revealed that graves long assumed to contain family members were not related by blood. The findings, reported by ScienceDaily, challenge archaeologists' traditional reliance on grave arrangement and proximity to interpret kinship in medieval cemeteries, suggesting burial practices reflected social bonds or community ties rather than family lineage.

AlterNet reports that Republicans continue to defer to Donald Trump despite political costs, pointing to scientific research as offering an explanation for the pattern.
