Your Brain: Perception and Control
2026/2/17 | 18 mins.
Are we really in control of our own minds? Research suggests our sense of control may be far more fragile – and far stranger – than we imagine. From moments when the body seems to act without us, to the eerie ways our brains can warp what we think we’ve heard, scientists are uncovering a picture of the mind that’s anything but straightforward. And beneath it all lies a surprising discovery: the brain is less an observer of reality than a prediction engine, forever guessing what comes next.

Hunt for the Oldest DNA
2026/2/03 | 19 mins.
Scientists have discovered the oldest DNA ever found: tiny fragments hidden in the dirt. The idea that soil could hold genetic traces from creatures that vanished millions of years ago seemed impossible – until one researcher had the wild idea to go and look. But how did he find DNA that most scientists thought could never survive? What forgotten worlds can this buried DNA reconstruct? And what might these revelations tell us about our own future on a rapidly changing planet?
