'Last Hope' Experiment Finds Evidence for Unknown Particles

By NATALIE WOLCHOVER

This week's long-anticipated announcement by Fermilab's Muon g-2 team appears to solidify a tantalizing conflict between nature and theory. But a separate calculation, published at the same time, has clouded the picture.

Mathematicians Settle Erdős Coloring Conjecture

By KELSEY HOUSTON-EDWARDS

Fifty years ago, Paul Erdős and two other mathematicians came up with a graph theory problem that they thought they might solve on the spot. A team of mathematicians has finally settled it.

Around the Web

A Bad Explosion, Then a Good Explosion
The Chicxulub asteroid that wiped out the dinosaurs also seeded an explosion of biodiversity that has become the Amazon rainforest, Rachel Newer reports for Scientific American. Researchers keep learning more about the ancient cataclysm. Microscopic marine fossils have helped tease the asteroid's effects apart from volcanic ones in the geological record, Josh Sokol reported for Quanta.

They Met on eHominin
45,000-year-old DNA plucked from a Bulgarian cave reveals mixing between modern humans and Neanderthals that shows up in far-flung, present-day populations, Bruce Bower reports for Science News. Fast computers and new genomic techniques are helping researchers to make more sense of humanity's messy evolutionary history, identifying specific instances of gene swapping between ancient hominins, Jordana Cepelewicz reported for Quanta in 2019.
