Life could use a more expansive genetic code in theory, but new work shows that improving on three-letter codons would be a challenge.

A new analysis of W bosons suggests these particles are significantly heavier than predicted by the Standard Model of particle physics.

The optical properties of mitochondrial bundles in the retina may improve how efficiently the eye captures light.

The result could help researchers answer a larger question about flattening objects from the fourth dimension to the third dimension.

The American mathematician invented entire new ways to understand shapes and spaces.

Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.

An experiment conducted on hybrid matter-antimatter atoms has defied researchers’ expectations.

A new proof significantly strengthens a decades-old result about the ubiquity of ways to represent whole numbers as sums of unit fractions.

The discovery that short peptides can form spontaneously on cosmic dust hints at more of a role for them in the earliest stages of life’s origin, on Earth or elsewhere.
