Venus Aerospace raises $91M to build its ‘detonation’ rocket engine

A Texas startup has raised $91m to build a rocket engine most of the industry once wrote off as too hard. Venus Aerospace announced a $91m Series B to develop its Rotating Detonation Rocket Engine, or [...]

Magnetars drag spacetime to power superluminous supernovae

Frame-dragging may explain an odd pattern seen in the brightest supernovae. [...]

Black hole mergers put limits on star-destroying supernovae

Pair instability supernovae create a "mass gap" in black holes. [...]

Four AI agents coordinating in real time outperformed Claude Opus 4.8 on enterprise coding tasks

As enterprise codebases grow, AI agents tasked with analyzing them are buckling under the weight of long-horizon tasks that require multiple interactions and tool calls. Dividing the work among a team [...]

Attackers scale deception with AI. Defenders need truth at machine speed.

Presented by SplunkAI has changed the economics of cyber deception.An attacker can now generate thousands of convincing phishing lures, fake identities, and tailored pretexts before a defender finishe [...]

Stanford's DeLM cuts multi-agent task costs 50% — without a central orchestrator

One of the assumptions behind today’s AI frameworks is that agents require a “boss” at the center; this orchestrator runs the show, routes requests, and makes sure the whole system doesn’t des [...]

Is Anthropic 'nerfing' Claude? Users increasingly report performance degradation as leaders push back

A growing number of developers and AI power users are taking to social media to accuse Anthropic of degrading the performance of Claude Opus 4.6 and Claude Code — intentionally or as an outcome of c [...]
