Sauropod tooth scratches reveal that some dinosaurs migrated seasonally, others ate a wide variety of plants, and climate strongly shaped their diets. Tanzania’s sand-blasted vegetation left especially heavy wear, offering rare insights into ancient ecosystems.

Artificial intelligence is reshaping law, ethics, and society at a speed that threatens fundamental human dignity. Dr. Maria Randazzo of Charles Darwin University warns that current regulation fails to protect rights such as privacy, autonomy, and anti-discrimination. The “black box problem” leaves people unable to trace or challenge AI decisions that may harm them.

Scientists have uncovered a sweet twist in the body’s fight against cancer. Glucose, best known as the fuel that powers our cells, also helps immune cells called T cells communicate and organize their attack on tumors. By turning sugar into special building blocks, T cells strengthen their internal signals and become far more effective cancer killers.

Some animals don’t age at the same pace, and flamingos may hold the key to why. A decades-long study in France reveals that resident flamingos, which stay put, enjoy early-life advantages but pay later with accelerated aging, while migratory flamingos endure early hardships yet age more slowly. This surprising link between movement and longevity challenges old assumptions and offers new insights into the science of aging.

Children with higher blood pressure as young as age 7 face a sharply increased risk of dying from cardiovascular disease by their mid-50s, according to a massive decades-long study. Researchers found that even moderately elevated readings, not just full hypertension, raised the danger, with risks climbing as much as 40–50%.

Physicists at the University of Colorado Boulder have created the first time crystal that humans can actually see, using liquid crystals that swirl into never-ending patterns when illuminated by light. This breakthrough builds on Nobel laureate Frank Wilczek’s 2012 theory of time crystals—structures that move forever in repeating cycles, like a perpetual motion machine or looping GIF. Under the microscope, these crystals form colorful, striped patterns that dance endlessly, opening possibilities for everything from anti-counterfeiting features in money to futuristic methods of storing digital information.

Cambridge scientists discovered that thin, weak zones in Earth’s plates helped spread Iceland’s mantle plume across the North Atlantic, explaining why volcanic activity once spanned thousands of kilometers. These ancient scars not only shaped the landscape but still influence earthquakes and could point to untapped geothermal energy.

Northwestern scientists have developed a new nanostructure that supercharges CRISPR’s ability to safely and efficiently enter cells, potentially unlocking its full power to treat genetic diseases. By wrapping CRISPR’s tools in spherical DNA-coated nanoparticles, researchers tripled gene-editing success rates, improved precision, and dramatically reduced toxicity compared to current methods.

Every year, Panama’s Pacific coast benefits from powerful seasonal winds that drive nutrient-rich waters to the surface, sustaining fisheries and protecting coral reefs. But in 2025, for the first time in at least four decades, this crucial upwelling did not occur. Scientists suspect weakened trade winds linked to climate disruption played a role, leaving cooler waters absent and fisheries under stress.

A common hay fever nasal spray was found to cut COVID-19 infections by two-thirds in a clinical trial, while also reducing rhinovirus cases. Researchers believe it could serve as an easy, low-cost preventive measure, pending further studies.

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf planet, this mysterious world challenges long-held assumptions about the “empty” space beyond Neptune. Its unusual trajectory sets it apart from other distant bodies and may even cast doubt on the controversial Planet Nine hypothesis.

A sweeping new study reveals that humanity has already pushed 60% of Earth’s land outside its safe biosphere zone, with 38% in a high-risk state. By analyzing centuries of data, researchers mapped how human demands on biomass—from farming to energy production—have destabilized ecosystems worldwide. Europe, Asia, and North America show the deepest disruptions, reflecting centuries of land-use change.

A newly discovered species of Bartonella bacteria in Brazil’s Amazon sand flies shares DNA similarities with dangerous Andean strains. Scientists stress the need for further studies to see if it can infect humans and spread beyond its known regions.

For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a powerful asteroid impact billions of years ago.

Sucralose, the sugar substitute in many diet products, may weaken cancer immunotherapy by altering gut bacteria and reducing arginine levels needed for immune cells. But supplementation with arginine or citrulline could counteract this effect, pointing to new clinical trial possibilities.

Satellite data reveals sea-level rise has unfolded almost exactly as predicted by 1990s climate models, with one key underestimation: melting ice sheets. Researchers stress the importance of refining local projections as seas continue to rise faster than before.

Hidden fat wrapped around organs, known as visceral fat, has now been linked to faster heart aging. Using AI and imaging from more than 21,000 people in the UK Biobank, scientists found that this invisible belly fat accelerates stiffening and inflammation of the heart, while fat stored around hips and thighs may actually protect women.

Getting a smartphone before age 13 may drastically increase the risk of poor mental health later in life, according to data from more than 100,000 people. Early use is linked to suicidal thoughts, aggression, and detachment, largely driven by social media, cyberbullying, and lost sleep. Researchers urge urgent action to restrict access and protect young minds.

Two tiny pterosaurs, preserved for 150 million years, have revealed a surprising cause of death: violent storms. Researchers at the University of Leicester discovered both hatchlings, nicknamed Lucky and Lucky II, with broken wings—injuries consistent with being tossed through the air by powerful gusts. These storms not only claimed their lives but also created the rare conditions that preserved them so perfectly in the Solnhofen limestones.

A team of chemists has discovered how to transform PET plastic waste into BAETA, a material that captures CO2 with remarkable efficiency. Instead of ending up as microplastics in the environment, discarded bottles and textiles could become tools to combat climate change. The method is energy-friendly, scalable, and potentially lucrative, offering industries both sustainability and practicality.
