Weight is not an issue: How a 250kg kangaroo could still hop on two legs
A new study using fossil evidence suggests extinct giant kangaroos, some weighing up to 250kg, were physically capable of hopping. Researchers found their bones and Achilles tendons were strong enough to withstand the impact of jumping. While not as efficient as modern kangaroos for long distances, this capability could have been used for bursts of speed or escape.
The ocean floor is turning into the world’s biggest plastic dump site killing hundreds of underwater species
The ocean floor is becoming a massive plastic dump, with debris accumulating in deep-sea canyons and harming marine life. Scientists warn that this hidden pollution, dominated by plastics and ghost fishing gear, poses a long-term threat to hundreds of species. Prevention is the only viable solution, as deep-sea cleanup is impractical.
Chinese company builds a device that can ‘see through’ your skin and show your veins instantly
A portable vein finder developed by Vivolight has gained attention for its ability to project a live vein map onto the skin. This near-infrared light technology aids clinicians in quickly and accurately locating veins for medical procedures, especially in challenging cases. The device offers a practical solution for routine medical care, improving efficiency and patient comfort.
Meet Dr Gladys West: The mathematician who helped make GPS dies at 95
Dr. Gladys West, a pioneering mathematician whose work in satellite geodesy was crucial for modern GPS accuracy, has passed away at 95. For decades, her vital contributions to modeling Earth's shape and gravitational forces remained largely unrecognized. Her legacy is now celebrated, highlighting her impact on everyday navigation and her role as a barrier-breaking figure in STEM.
Scientists discovered mysterious cave handprint that could be the oldest rock art ever found
An ancient handprint discovered in an Indonesian cave, dated at least 67,800 years old, may be the world's oldest rock art. This significant find pushes back the timeline for early human symbolic expression and artistic capabilities. Researchers are debating whether modern humans or another ancient group created the unique, pointed-finger outline, offering a glimpse into early human minds.
