Streamlined Robotic Manta Ray Swims Faster with a Simplified, Efficient Design

Just two years ago, a tiny robotic manta ray set a record as the fastest-swimming soft-bodied robot. Now, its upgraded successor has shattered that record while using less energy in the process. The original 22.8-mm-long robot was developed by Assoc. Prof. Jie Yin and his team at North Carolina State University. It featured two flexible […]

The Shifting Borders Phenomenon Redefining Country Shapes

Environmental Science / Mauro Lucas

When the Swiss and Italian governments collaborated last year to redraw their shared alpine borders, the retreat of glaciers brought a growing global challenge into sharp focus: how to manage shifting borders defined by natural landmarks. This issue is expected to affect many nations as environmental changes continue to reshape the landscape. Fortunately, the process

Mathematician Solves Long-Standing Moving Sofa Puzzle

Physics / Samilton Santos

When it comes to moving furniture, mathematicians aren’t usually the first people we think to consult. And why would they be? For nearly six decades, they couldn’t definitively answer whether your stylish three-seater could navigate that tricky turn into your apartment hallway. However, Jineon Baek, a mathematics enthusiast from Yonsei University in South Korea, might

Researchers Uncover New Deep-Sea Predator, Dubbed Darkness

Biology, Science / Mauro Lucas

Earth’s oceanic trenches, plunging as deep as 11 kilometers (6.8 miles), remain one of the planet’s most mysterious realms. Their pitch-black waters endure crushing pressures of up to 1,088 atmospheres (16,000 pounds per square inch), yet life somehow thrives in these extreme environments. Despite decades of limited access, scientists are now unraveling the secrets of

An Unexpected Chemical May Be the Cause of Red Wine Headaches

Healthcare, Medicine / Samilton Santos

Red wine headaches have been a well-documented phenomenon since Roman times, likely dating back to the origins of winemaking itself, around 10,000 years ago. As chemists focused on winemaking, we set out to uncover the true culprit behind this age-old discomfort. Debunking Common Culprits Over the years, sulfites, biogenic amines, and tannins have been frequently

Study Finds Jupiter’s Volcanic Moon Io Is Not Powered by a Global Magma Ocean

Astronomy, Planetary Science, Science / Samilton Santos

Io, one of Jupiter’s moons, holds the title of the most volcanically active body in the Solar System, boasting around 400 volcanoes and vast lava flows across its surface. However, contrary to earlier theories, a recent study suggests that this volcanic activity is not driven by a global magma ocean beneath its crust. New Study
