Gold is weird. It's one of the few metals that doesn’t really oxidize. Even silver and copper—from the same column of the periodic table—form weak oxides. Naively, you might expect that gold would tarnish just like silver. Gold also sits right next to platinum, but it has none of that metal’s catalytic properties. Then came gold nanoparticles that acted like catalysts, and we were confused by their apparent willingness to take part in chemical reactions. Now, a pair of scientists has explained that gold’s inertness isn’t inherent to the atom but rather to the surfaces that gold crystals form.
The scientific community has a plan for achieving fusion power. It involves getting a better understanding of how to control fusion in a tokamak-style reactor using the currently under construction ITER reactor, and then using that knowledge to build DEMO-style plants.
People often speak metaphorically of the heartbeat or pulse of a city, but according to the authors of a new paper published in the Proceedings of the National Academy of Sciences, cities do indeed have an "urban pulse"—an indication of urban "metabolic activity" that can be measured to suss out telltale patterns. And those patterns could help inform future public policy around urban planning. The precise definition of urbanization has shifted over the centuries. Zhe Zhu of the University of Connecticut and his fellow authors adopted a broad version for their study.

Researchers have analyzed a high-severity vulnerability in Linux that’s able to escalate untrusted users to root by exploiting a bug you don't often see: a single errant character inside the kernel. The vulnerability, tracked as CVE-2026-23111, is located in nf_tables, a subsystem of the Linux kernel that provides packet filtering capabilities.
Paramount Skydance is accusing Netflix of maintaining a campaign against its proposed acquisition of Warner Bros. Discovery (WBD). In a June 5 letter (PDF) addressed to Jared A. Hughes, acting section chief of the Media, Entertainment, and Communications Section of the US Department of Justice's (DOJ's) Antitrust Division, and A. Maya Kahn, a trial attorney for the Antitrust Division, and first reported on by Politico today, Paramount chief legal officer Makan Delrahim accused Netflix of trying to influence stakeholders about the merger.

Bleaching has devastated reefs around the world, raising fears of an irreversible shift. Yet new interventions have revealed that corals can be remarkably resilient if we can give them enough help to recover
