A distant icy object beyond Neptune has revealed a surprising hint of activity, raising a mystery that could change how astronomers think about the smallest worlds at the edge of the Solar System.
Ancient giant octopuses may have been smarter, bigger, and fiercer than expected
Modern octopuses are known as escape artists of the sea, soft-bodied, elusive, and almost impossible to pin down. But a new fossil discovery is challenging that familiar image. Hidden inside ancient rocks, scientists have found rare clues that suggest the early story of octopuses may have been far more dramatic than anyone expected.

How this robot could accelerate the search for life
Planetary rovers may seem like bold explorers, but in reality they work under tight limits. On Mars, even simple instructions take minutes to arrive, so every move must be planned carefully. That keeps missions safe, but it also raises a question: if robots move slowly and stop often, how much of another world can we really study?

Can working out improve brain health and memory? Here’s what to know
We’ve all experienced that post-workout mental clarity - that feeling of being a bit "sharper" after hitting the gym or going for a run. But what is actually happening inside our heads to cause that?
Research gives us an unprecedented look into the brain right after physical activity, and the findings might just change how you view a quick sweat session.

A nearby supernova could help explain why Earth-like planets may be more common than we thought
A young solar system does not just build planets from dust and gas. It can also be shaped by what happens nearby, including the death of a massive star. New research suggests that a supernova at the right distance could quietly change a planet’s ingredients from the start, and that this setup may be more common than scientists once assumed.

These Shape-Shifting Flowers Could One Day Deliver Drugs Inside Your Body
Imagine a field of microscopic flowers that can fold, unfurl, and even kick off a chemical reaction without a gardener in sight. Researchers at the University of North Carolina have at Chapel Hill built just such shape-shifting “soft robots,” and the most interesting part isn’t what they are, but what they might be able to do.
