Cuttlefish Communicate Using Elaborate Arm Movements and Water Vibrations

2025-05-07
Cuttlefish Communicate Using Elaborate Arm Movements and Water Vibrations

Scientists have discovered that cuttlefish use distinct arm movements to communicate, employing a multi-sensory system involving both visual cues and water vibrations. Researchers identified four distinct arm gestures, combined with skin color changes, that appear to convey different meanings. Remarkably, cuttlefish seem to perceive these signals differently depending on their orientation, similar to how humans perceive faces. Furthermore, experiments revealed that cuttlefish can detect these signals through water movement, likely utilizing their lateral line and statocysts. This dual-channel communication system adds a new dimension to our understanding of cephalopod intelligence and animal communication.

Structured Errors in Rust: Weighing the Tradeoffs

2025-06-01

This article explores the advantages and disadvantages of using structured errors (e.g., with `thiserror`) versus `anyhow` in Rust applications. Based on experience maintaining a large Rust web server, the author argues that custom error types, while increasing code and maintenance overhead, offer significant benefits: clearly showing all potential failure modes of a function, improving code readability and review; creating more descriptive interfaces; avoiding redundant error messages; enforcing context addition; and allowing for extra data and functionality. However, drawbacks include increased code volume, naming challenges, maintenance overhead, and potential performance concerns. The author concludes that the trade-off should be assessed case-by-case, suggesting that in large applications, the advantages of structured errors may outweigh the costs.

In Defense of Adverbs: A Counterintuitive Approach to Writing

This article challenges the common writing advice to avoid adverbs. The author argues that adverbs are a valuable part of language and shouldn't be dismissed outright. The piece dissects the misconceptions surrounding adverb use, highlighting how adverbs can be precise and effective when used intentionally, rather than merely repeating information already conveyed. Using Denis Johnson's work as an example, the author demonstrates how adverbs contribute to unique style and character development. Ultimately, the article emphasizes the importance of practical principles over rigid rules in writing.

LHCb Observes New Antimatter Asymmetry

The LHCb experiment at the Large Hadron Collider has observed a new difference between matter and antimatter in baryons, marking the first observation of CP violation in this type of particle. This discovery is a significant step towards understanding the universe's matter-antimatter imbalance. While the observed CP violation aligns with the Standard Model, it's insufficient to explain the cosmic asymmetry, suggesting the existence of undiscovered particles or new physics beyond the Standard Model.

FCC Approves Verizon's $20B Frontier Acquisition After DEI Policy Drop

The FCC, led by Chairman Brendan Carr, approved Verizon's $20 billion acquisition of Frontier Communications after Verizon pledged to end its diversity, equity, and inclusion (DEI) policies. Carr hailed the move as a positive step for equal opportunity and the public interest. This approval comes as Paramount Global and Skydance Media's $8 billion merger remains pending, potentially due to DEI concerns. Carr previously indicated he would block mergers involving companies promoting DEI programs. The acquisition allows Verizon to upgrade Frontier's network in 25 states, potentially bringing fiber to over 1 million homes annually.

An Eight-Year-Old Polyomino Tiling Algorithm: Backtracking Search with Heuristics

2025-03-15

This article details an algorithm for solving the polyomino tiling problem. The core idea is to transform the geometric problem into a graph theory problem and use a backtracking search algorithm with various heuristics. First, the algorithm preprocesses to calculate all possible placements, constructing a bipartite graph representing all possibilities. Then, a backtracking search algorithm finds a subset of placements satisfying the conditions, optimized by heuristics such as prioritizing constrained grid points and splitting the grid. The algorithm demonstrates good generality and robustness in handling arbitrary grid shapes and polyomino sets. The author also discusses limitations and future improvements, such as transforming the problem into a SAT problem for solution.
