Comment This paper's main contribution (Score 4, Informative) 26

Existing methods for coherence-based quantum key distribution rely on ultra-stable optical cavities and cryogenic photon detectors, which limit scalability and practical deployment.

This study replaces that setup with a non-cryogenic, scalable system using off-band phase stabilization and commercial telecom infrastructure, yet still achieves 254 km secure key distribution, effectively doubling the practical distance for real-world QKD (according to the authors).

I tried to find out what they are going to do exactly, and this is the only relevant part of their statement:
"Today we’re announcing Mechanize, a startup focused on developing virtual work environments, benchmarks, and training data that will enable the full automation of the economy.
We will achieve this by creating simulated environments and evaluations that capture the full scope of what people do at their jobs. This includes using a computer, completing long-horizon tasks that lack clear criteria for success, coordinating with others, and reprioritizing in the face of obstacles and interruptions."

Due to their isotopic similarity to terrestrial rocks across a range of elements, the meteorite group that is thought to best represent Earth's building blocks is the enstatite chondrites (ECs)... Here, we explore the amount of hydrogen in ECs as well as the phase that may carry this element using sulfur X-ray absorption near edge structure (S-XANES) spectroscopy. We find that hydrogen bonded to sulfur is prevalent throughout the meteorite, with fine matrix containing on average almost 10 times more H-S than chondrule mesostasis. Moreover, the concentration of the H-S bond is linked to the abundance of micrometre-scale pyrrhotite (Fe1-xS, 0 x 0.125). This sulfide can sacrificially catalyse a reaction with H2 from the disk at high temperatures to create H2S, which could be dissolved in adjoining molten silicate-rich material. Upon rapid cooling, this assemblage would form pyrrhotite encased in submicron silicate-rich glass that carries trapped H2S.

These findings indicate that hydrogen is present in ECs in higher concentrations than previously considered and could suggest that this element may have a systematic, rather than stochastic, origin on our planet.

> The academic publisher Sage Publications has retracted studies used by a Texas judge in a ruling that would suspend federal approval of the abortion pill mifepristone. The retractions, Sage said, were based on unreliable data and conflicts of interest around the authors’ ties to the anti-abortion movement.
