What causes adversaries to escalate conflicts into costly, prolonged wars even when neither side wants to fight? And in the fog of war, what might help them break that cycle and find a path to peace? https://phys.org/news/2026-10-fog-war-game-based-boundaries.html Social Sciences Wed, 21 Oct 2026 16:00:13 EDT news711805381 Over the past 30 years, Swiss barn owls have become more reddish-brown and more heavily spotted. By analyzing the genomes of more than 3,000 birds, scientists at the University of Lausanne identified the genetic variants linked to these changes in plumage and revealed natural selection at work. Their findings, published in Nature Communications, show that evolution can happen rapidly in the wild. https://phys.org/news/2026-10-swiss-barn-owls-gradually.html Plants & Animals Wed, 21 Oct 2026 15:00:10 EDT news711803641 Bacteria and the viruses that infect them—known as phages—coexist in soils, oceans and living organisms. Scientists have long thought this coexistence reflects a microscopic version of an evolutionary arms race: As parasites and hosts continually adapt to one another, both evolve ways to survive. But a joint study by researchers at the University of Maryland and the University of Exeter shows different pathways to coexistence. https://phys.org/news/2026-10-scientists-migration-mechanism-enabling-bacteria.html Cell & Microbiology Wed, 21 Oct 2026 14:00:52 EDT news711792422 Keeping to warm climates throughout their 250-million-year history may have helped crocodiles and their relatives survive the asteroid that killed the dinosaurs, finds a new study led by UCL (University College London) researchers. https://phys.org/news/2026-10-climates-crocodiles-outlast-dinosaurs.html Evolution Wed, 21 Oct 2026 14:00:49 EDT news711792541 Whenever a cell divides, it has to split its chromosomes perfectly between two daughter cells, and even a single mistake can be disastrous. Now, researchers from Japan have found that one of the key structures that makes this possible takes a surprising shape: a hollow sphere. https://phys.org/news/2026-10-chromosome-anchors-hollow-shells-cell.html Cell & Microbiology Wed, 21 Oct 2026 14:00:19 EDT news711712921 Despite being known for more mundane uses such as sticking notes to refrigerators or keeping bags shut, magnetization is one of the most fundamental and useful properties of a material.

To build these networks, physicists need to devise strategies that allow distant particles to share quantum states, preserving them long enough to perform calculations or enable communication between devices. https://phys.org/news/2026-10-atomic-memory-distant-ions-entangled.html Optics & Photonics Wed, 21 Oct 2026 07:40:12 EDT news711706392 In the early 1980s, scientists observed an anomaly. Embedded within cell membranes, they identified ion channels with extraordinarily high conductance. These so-called "BK" (Big K, or Big Potassium) channels had roughly 10 times the unitary conductance (i.e., conductance per individual channel molecule) of other potassium channels, enabling much more efficient, rapid transport of potassium ions. And while later structural characterization explained how this happened, no one could understand why. That is, until now. https://phys.org/news/2026-10-current-calcium-longstanding-ion-channel.html Evolution Wed, 21 Oct 2026 05:00:06 EDT news711713221 For thousands of years, Indigenous peoples have passed down their traditions and culture through oral storytelling.
