For billions of years, Earth’s continents have remained remarkably steady, providing the groundwork for mountains, ecosystems, and human civilization. Yet the reason behind their long-term stability has puzzled scientists for more than a century. Now, researchers from Penn State and Columbia University have uncovered strong evidence explaining how the continents formed and maintained their endurance,…

Could Mars have once supported life? Scientists still don’t have proof. Yet some of the planet’s strange surface features might seem to hint at it. Earth scientist Dr. Lonneke Roelofs of Utrecht University set out to study the origin of mysterious gullies carved into Martian dunes. In her laboratory experiments, she discovered that blocks of…

Researchers at Johns Hopkins Medicine report that they have identified how mammalian brains build intricate networks of tiny tubes that move toxins in and out of brain cells, much like pneumatic tubes send items through systems in factories and stores. Their experiments, which used genetically modified mice and advanced imaging tools, were supported by the…

On July 1, astronomers detected a strange, fast-moving object racing toward the Sun. Named 3I/ATLAS, this unusual traveler immediately stood out for one remarkable reason: its orbital path revealed that it had come from beyond our Solar System. This marked only the third time in history that scientists have identified an interstellar visitor entering our…

A minuscule parasitic worm capable of springing into the air up to 25 times its own body length can latch onto flying insects with the help of static electricity, according to new research. The findings, published in PNAS, focus on the nematode Steinernema carpocapsae and come from a collaboration between scientists at Emory University and…
