Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the...
Satellite Launch Pollution Rapidly Accumulating in the Upper Atmosphere
The potent pollution from so-called “megaconstellation” satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, finds a new study led by UCL researchers.
Short Exposures to Common Air Pollutants Shown to Have Distinct Impacts on Lung Function and Brain Activity
New research by a collaboration of UK‑based scientists has revealed that common indoor and outdoor air pollutants can alter both brain and respiratory function within just four hours of exposure, offering key insights into how air pollution impacts brain health and may contribute to dementia risk.
Sea Level Rise is Swallowing Mid-Atlantic Farmland Faster Than Expected, Study Finds
Ghost forests, the cemetery-like groupings of dead trees killed by saltwater intrusion, have become haunting symbols of sea level rise overtaking land along the Mid-Atlantic coast.
Hidden earthquake faults beneath Seattle may be more dangerous than expected
A hidden network of earthquake faults running beneath Seattle may be far more active than scientists realized. New research reveals that smaller “secondary” faults in the Seattle Fault Zone appear to rupture roughly every 350 years — much more often than the massive main fault that has long worried geologists.
Rare graves reveal a lost world of Bronze Age Europe hidden for 3,000 years
Scientists have uncovered remarkable new details about Bronze Age life in Central Europe by studying rare burials untouched by cremation. The research reveals communities experimenting with new foods, burial rituals, and cultural connections while largely staying rooted in their local homelands.
Antarctic glacier collapses at record speed as Hektoria retreats 15 miles in just 15 months
Antarctica’s Hektoria Glacier collapsed with shocking speed, retreating 15 miles in only 15 months and setting a modern record for grounded ice loss. Scientists say warming conditions and ocean-driven instability turned the glacier from seemingly stable to rapidly unraveling almost overnight.
Plant believed extinct for 60 years suddenly reappears
A random photo snapped in the Australian outback has led to the rediscovery of a plant thought extinct for nearly 60 years — proving that ordinary people with smartphones are quietly transforming science. After bird bander Aaron Bean uploaded pictures of a strange shrub to iNaturalist, botanist Anthony Bean immediately...
Scientists think they’ve cracked the mystery of human right-handedness
A new study suggests humans became overwhelmingly right-handed because of two major evolutionary shifts: walking on two legs and developing much larger brains. Researchers found that as human ancestors evolved, their right-hand preference steadily intensified — transforming a mild tendency into one of humanity’s most distinctive traits.
Stunning fossil discovery in Ethiopia rewrites human origins
A stunning fossil discovery in Ethiopia shows that early Homo and a previously unknown Australopithecus species lived together around 2.6 to 2.8 million years ago. The find overturns the classic “ape-to-human” progression and paints human evolution as a crowded, branching tree with multiple species coexisting. Scientists dated the fossils using...
