Scientists have uncovered new evidence that Stonehenge’s six-ton Altar Stone was deliberately transported hundreds of kilometers from Scotland by ancient people. The feat would have required extraordinary planning, teamwork, and determination, revealing a surprisingly sophisticated level of organization thousands of years ago.
An invisible forever chemical rain is falling across the planet
A surprising study suggests that chemicals introduced to protect the ozone layer may have unintentionally created a growing global pollution problem. Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tonnes of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's...
South Australia’s koala boom could end in mass starvation
South Australia’s koala population has grown so large that it may be heading toward a self-made disaster, with forests struggling to support the animals. Researchers say targeted fertility control could prevent widespread starvation and habitat collapse before it’s too late.
Scientists may have debunked one of humanity’s oldest habits
Ancient grooves on human teeth, once hailed as evidence of tooth-picking, may simply be the result of natural wear, according to a new study of wild primates. The research also revealed that a common modern dental defect appears to be uniquely human, hinting that today's lifestyles may be reshaping our...
Everyone thought these helmets were Roman until scientists uncovered the truth
Researchers have solved a decades-old mystery by showing that a cache of 43 helmets found off the Spanish coast is medieval, not Roman. The remarkable discovery exposes a thriving weapons trade network that connected Mediterranean powers during a time of piracy, warfare, and growing demand for military equipment.
Scientists sound the alarm as dangerous amoebas spread globally
Scientists warn that free-living amoebae may be an underappreciated public health threat, capable of causing deadly infections and shielding other dangerous microbes from water treatment. Climate change and aging infrastructure could help these resilient organisms spread more widely in the years ahead.
Giant fire tornadoes could clean up oil spills faster with less pollution
Researchers have shown that controlled fire whirls can clean up oil spills faster and more cleanly than traditional burning methods. The spinning flames consumed up to 95% of the oil, cut soot emissions by 40%, and could help prevent spills from reaching sensitive marine habitats.
Scientists are seriously asking if bees and ChatGPT are conscious
New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar. Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious...
Octopuses use mirrors to find food they cannot see
Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing...
Scientists discover vast hidden structure beneath Antarctica’s ice
A giant fan-shaped network of hidden basins has been discovered beneath East Antarctica, revealing that several well-known subglacial features are actually part of one massive geological structure. The finding sheds new light on Antarctica’s ancient tectonic history and could help scientists better understand how the ice sheet behaves today.
