How do black holes merge and make gravitational waves? Maybe with a little help from their friends.

The ancient Greeks wondered when “irrational” numbers can be approximated by fractions. By proving the longstanding Duffin-Schaeffer conjecture, two mathematicians have provided a complete answer.

Polynomials aren’t just exercises in abstraction. They’re good at illuminating structure in surprising places.

Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.

Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”

Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.

To avoid passing on new mutations to offspring, plants may minimize the number of divisions by the stem cells that make flowers and seeds.

A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.
