Summary

Recent studies indicate that plastic aligners, such as Invisalign, release microplastic particles into the mouth due to factors like saliva, mechanical friction, and time. A 2025 PLOS One study found Invisalign released the fewest but smallest particles (12–23 μm), while a 2023 study showed all seven tested brands released microplastics within a week. Separately, the AI Security Institute (AISI) reports that frontier AI models' cyber attack capabilities, specifically their 80%-reliability cyber time horizon, doubled every 4.7 months since late 2024, accelerating from an 8-month doubling time in November 2025. Models like Claude Mythos Preview and GPT-5.5 have significantly surpassed this trend, achieving near-100% success rates on narrow cyber tasks with a 2.5M token limit. Palo Alto Networks confirms this shift, noting a 50% improvement in coding efficiency for latest frontier models, enabling autonomous operation and redefining the threat landscape with rapid vulnerability discovery, exploit chaining, compressed attack cycles, and an expanding unsupervised attack surface.

Key takeaway

For CTOs and VPs of Engineering assessing cybersecurity strategy, the rapid acceleration of AI cyber attack capabilities demands immediate re-evaluation of defense postures. Your organization must move beyond incremental security improvements to prepare for autonomous AI operators, focusing on proactive vulnerability discovery, sophisticated exploit chaining, and achieving single-digit Mean Time to Respond (MTTR) to mitigate risks from an expanding, unsupervised attack surface.

Key insights

AI cyber attack capabilities are doubling every 4-5 months, creating an urgent and evolving threat landscape.

Principles

Method

The AI Security Institute (AISI) measures AI cyber capability advancement by tracking the doubling time of frontier models' 80%-reliability cyber time horizon, using a 2.5M token limit on narrow cyber suites.
