The Southern Taurids peaked around Nov. 5, and the Northern Taurids peak around Nov. 12. Each produces only a handful of meteors per hour, but NASA says an occasional bright fireball can make the wait worthwhile.

By studying a real fish swimming among virtual fish, researchers uncover the rules that a fish follows when schooling. The results suggest that schooling fish focus on a single influential neighbor.

Color map of cosmic microwave background temperature around stacked galaxy clusters, drawn as a circle split down the middle by a dashed vertical line. The left half is shaded blue and the right half red, over a faint blue and red background. A small curved arrow at the bottom marks rotation around the dashed line.

When the dense helium cores of two red giants collide, the merger could produce high-energy neutrinos, finds a study in Physical Review D. IceCube could expect about one such neutrino from a single merger up to 180,000 light years away.

Simulation of two colliding red giant cores. A turbulent cloud of glowing gas fills the frame against a dark background, shading from dark red at the edges through orange to a white-hot center, where two small black circles sit side by side.

Congratulations again to Francis Halzen, winner of the 2026 @NobelPrize in Physics. Physical Review Letters published two key IceCube Collaboration studies behind this prize.

Swipe through 15 years of #NobelPrize-winning research that appeared in PRL.
Title slide reading "A Snapshot of PRL's Nobel Legacy" with a swirling blue and green particle image inside an oval frame, and "Swipe for discoveries through the years" below it with a forward-arrow icon. Two entries are shown: “2026, High-Energy Astrophysical Neutrinos,” illustrated with a vibrant 3D visualization showing colorful vertical columns made of stacked spheres glowing in yellow, orange, red, and green against a white background, citing PRL 111 021103 (2013) and PRL 113 101101 (2014). “2025, Macroscopic Quantum Tunneling,” illustrated with a schematic of an apparatus with a Pt-195 NMR thermometer, citing PRL 53 1260 (1984), PRL 55 1543 (1985), and PRL 55 1908 (1985).Four Nobel-linked discoveries: “2023, Attosecond Pulses,” illustrated with a diagram of a wave packet and two green V-shaped curves, one straight and one tilted, with pink spheres above, citing PRL 42 1127 (1979), PRL 48 1814 (1982), PRL 73 2180 (1994), PRL 77 1234 (1996), and PRL 81 297 (1998). “2022, Quantum Nonlocality,” illustrated with a schematic of a photon entanglement experiment using polarizing beam splitters and detectors, citing PRL 23 880 (1969), PRL 28 938 (1972), PRL 47 460 (1981), PRL 49 91 & 1804 (1982), PRL 71 4287 (1993), PRL 80 3891 (1998), and PRL 81 1345 (1999). “2021, Complex Systems,” illustrated with a grid of green dots with arrows showing a disordered spin system, citing PRL 43 1754 (1979), PRL 50 1946 (1983), PRL 52 1156 (1984), PRL 109 205501 (2012), and PRL 127 038001 (2021). “2020, Black Hole Formation,” illustrated with an artist's rendering of warped spacetime around a glowing blue sphere, citing PRL 10 66 (1963) and PRL 14 57 (1965).
