For decades, astronomers weren’t able to find all of the atomic matter in the universe. A series of recent papers has revealed where it’s been hiding.

How much stock should we put in mathematical models of evolution that have not been validated by rigorous empirical data?

The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math.

An upstart field that simplifies complex shapes is letting mathematicians understand how those shapes depend on the space in which you visualize them.

Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.

Computer vision researchers have uncovered a world of visual signals hiding in our midst, including subtle motions that betray what’s being said and faint images of what’s around a corner.

Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.

Rosaly Lopes has visited dozens of active volcanoes on Earth and discovered even more elsewhere in the solar system. Her work is helping to establish whether volcanoes on distant moons could create conditions friendly to life.

Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.
