Singapore's National University of Science team has built the world's most accurate atomic clock using a single lutetium ion, losing only one second every 260 billion years. The breakthrough surpasses previous records held by Chinese and US researchers and could advance timekeeping standards and fundamental physics research.
An article documenting the implementation of Shamir's Secret Sharing (SSS) in Rust as a building block for Multi-Party Threshold Cryptography research. SSS uses polynomials to split secrets into shares such that any k of n parties can reconstruct the secret, but fewer than k parties learn nothing. The post explains the mathematical foundations and notes that real-world implementations use finite fields rather than integers to prevent information leakage.
Anthropic's Frontier Red Team analyzes GLM-5.3, an AI model from Zhipu AI that autonomously builds cyber exploits with capabilities matching Claude Mythos Preview. Unlike safeguarded US models, GLM-5.3 was released publicly without meaningful safeguards, allowing attackers to bypass them 64-100% of the time, significantly increasing malicious cyber capabilities while also benefiting defenders.
Anthropic's Frontier Red Team analyzed GLM-5.3, an AI model by Zhipu AI with strong autonomous cyber exploit capabilities released without meaningful safeguards. Unlike safeguarded Claude models, GLM-5.3's protections can be bypassed 64-100% of the time, significantly increasing capabilities available to malicious cyber actors, though these same capabilities also benefit defensive security work.
TrawlSec is a threat intelligence monitoring platform that automatically generates SOC 2, ISO 27001, and NIS2 compliance evidence by continuously matching vulnerability feeds to your assets, capturing reviewer dispositions, and producing audit-ready reports without manual reconstruction.
