(Alasabyss/Creatas Video+/Getty Images Plus)Quantum entanglement, a cornerstone of modern physics, involves correlating two or more unmeasured particles so that their properties intertwine and mirror each other. When one particle is measured, its counterpart’s corresponding properties instantly solidify, even when the two are separated by vast distances.In a groundbreaking development, physicists have introduced a bold...

One of the specimens of Saccus xixiangensis, no more than 1 millimeter in diameter. (Liu et al., Palaeogeogr. Palaeoclimatol. Palaeoecol., 2025)Tiny mineralized spheres are offering fresh insights into the history of life on Earth. These millimeter-sized fossils, over 535 million years old, are the fossilized embryos of early Cambrian animals.Belonging to the Ecdysozoa group—which includes insects,...
A groundbreaking discovery in the Ecuadorian Amazon could reshape our understanding of human history. Archaeologists have unearthed a massive structure buried beneath sediment and vegetation—a giant ship of mysterious origin that has remained concealed for over 10,000 years.The discovery occurred in the remote and hard-to-reach Pastaza province, where a team led by Dr. Isabel...

The viral claim suggests that coughing rhythmically can help individuals survive a heart attack when alone by keeping their heart beating. While the idea is dramatic and attention-grabbing, it has raised significant concerns among medical professionals.Origins...
Artist's impression of the brain's surprisingly slow speed of thoughtJieyu ZhengWe like to think of ourselves as quick thinkers, but new research from Caltech reveals that our brains process information at an astonishingly slow rate of about 10 bits per second. Despite our sensory systems gathering data 100 million times faster, this leisurely pace...
