Scientists combined fungus and bacteria into a “living material” that stays alive for up to a month. Fungi are master engineers capable of building vast networks underground. Now, researchers have harnessed their capabilities to create a living building material that could be a sustainable

Two studies found stem-cell therapies were safe and reduced symptoms, but bigger trials are still needed. Grabbing a coffee cup seems easy. But you need to be able to move your hand, stretch it out, and keep it steady. These movements are difficult for people with Parkinson’s disease. The disorder

Intercepting interstellar objects could transform fleeting encounters into profound scientific opportunities. In late 2017, a mysterious object tore through our solar system at breakneck speed. Astronomers scrambled to observe the fast moving body using the world’s most powerful telescopes. It was

In a first, the 3D reconstruction of a mouse brain links structure to activity. Let a mouse nose around a house, and it will rapidly find food and form a strategy to return to it without getting caught. Given the same task, an AI would require millions of training examples and consume a boatload of

A vast galactic survey suggests dark energy may not be constant after all. The great Russian physicist and Nobel laureate Lev Landau once remarked that “cosmologists are often in error, but never in doubt.” In studying the history of the universe itself, there is always a chance that we have got it
