These ultrabright flashes have recently been tracked for days, upending ideas about the cataclysms that create them.

In this month’s puzzle, math is a question of life or death.

Genomic surveillance of the SARS-CoV-2 virus can help control the current pandemic and prevent future ones. But the process is marred by insufficient data and geographic inequities.

Even in an incomplete state, quantum field theory is the most successful physical theory ever discovered. Nathan Seiberg, one of its leading architects, talks about the gaps in QFT and how mathematicians could fill them.

For all their triumphs, AI systems can’t seem to generalize the concepts of “same” and “different.” Without that, researchers worry, the quest to create truly intelligent machines may be hopeless.

Jupiter and Saturn should be freezing cold. Instead, they’re hot. Researchers now know why.

Researchers have finally seen how some smell receptors bind to odor molecules. The work yields new insights into one of the most mysterious and versatile senses.

In three towering papers, a team of mathematicians has worked out the details of Liouville quantum field theory, a two-dimensional model of quantum gravity.

Animals sculpt the optical properties of their tissues at the nanoscale to give themselves “structural colors.” New work is piecing together how they do it.
