Tiny ancient fish fossil with preserved brain offers clues to early fish evolution

Over 300 million years ago, a minnow-sized fish died and fell to the bottom of a prehistoric swamp near the village of Trawden, Lancashire, in northwest England. The remains of this tiny fish—known as Trawdenia planti—became fossilized, embedding proof of its existence in a layer

Polymer network reconfigures in sequence, helping elastomers stay tough under strain

Shock-absorbing sneaker soles are likely made of polyurethane, a highly elastic and tough polymer. The ability of these elastomers to absorb impact without breaking is extremely important for practical applications. While multiple strategies exist for enhancing elastomer toughnes

New star activity catalog could sharpen hunt for habitable worlds

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star's habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the p
