The LEGO Sauron’s Helmet and Barad-dur sets, both designed for adult collectors, offer very different experiences within Tolkien’s world. The helmet is a striking display piece focused on iconic symbolism, while Barad-dur is a larger, more interactive build meant for extended enjoyment.

Adapting the World’s Greatest Detective for the screen is challenging, and currently, Batman: The Animated Series does a better job of getting it right than any film has.
![Robust principal component analysis successfully recovers underlying low-rank plus sparse structure in synthetic matrices of size 100x80 with high probability, achieving a recovery success rate consistently exceeding 99.9% as quantified by a normalized reconstruction error of less than [latex]10^{-3}[/latex] across 10,000 independent trials.](https://arxiv.org/html/2601.21333v1/x4.png)
New research establishes rigorous guarantees for finding optimal solutions in robust principal component analysis, even when dealing with challenging, non-convex problems.

This month’s PlayStation Plus free games have been available to download since January 6th. They are Epic Mickey: Rebrushed, Need for Speed Unbound, and Core Keeper.

It’s difficult to measure the full impact, but PlayStation has undoubtedly been a major force in building the gaming community.
