Your Social Media Feed Is Built to Agree with You. What If It Didn’t?
The feedback loop is an essential component of the architecture of the social media echo chamber: a space where familiar ideas are amplified, dissenting voices fade, and beliefs can harden rather than evolve. A new study points to algorithm design as a potential way to reduce echo chambers—and polarization—online.

On Plum Island, DOE Trains Utilities, Protection Teams to Defend the Grid
Plum Island, just off New York’s northeastern coast, is a sparsely populated outpost with a century-long legacy, stretching back to the Spanish-American War, of playing an important role in helping protect the nation. More recently, scientists have used Plum Island to research lethal pathogens – threatening both humans and farm animals — for which there is no vaccines or treatment. Now, the island hosts exercises which train power companies, industry experts, and government officials to respond to disruptive cyberattacks.

Hacking the Grid: How Digital Sabotage Turns Infrastructure into a Weapon
The darkness that swept over the Venezuelan capital in the predawn hours of Jan. 3, 2026, signaled a profound shift in the nature of modern conflict: the convergence of physical and cyber warfare. The blackout was the result of a precise and invisible manipulation of the industrial control systems that manage the flow of electricity. This synchronization of traditional military action with advanced cyber warfare represents a new chapter in international conflict, one where lines of computer code that manipulate critical infrastructure are among the most potent weapons.

AI-enabled Intrusions: What Anthropic’s Disclosure Really Means
Last week, AI company Anthropic reported with ‘high confidence’ that a Chinese state-sponsored hacking group had weaponized Anthropic’s own AI tools to run a largely automated cyberattack on several technology firms and government agencies. The September operation is the first publicly known case of an AI system conducting target reconnaissance with only minimal human direction.
