Introduction Biological cells and machine learning systems might seem worlds apart—one is the foundation of life, the other a product of human engineering. Yet, when you dig deeper, there are striking similarities in how they evolve, adapt, and function. Both systems process vast amounts of information, respond to their environments, and improve over time through…

To draw an analogy between transcription factors in the epigenetic process and the attention mechanism in large language models (LLMs), let’s break down both concepts in plain English and connect them in a way that’s easy to grasp. The analogy will help illustrate how transcription factors “decide” which genes to focus on, much like how…

Introduction Epigenetics is the study of how gene expression is regulated without altering the DNA sequence itself. It’s like a set of instructions layered on top of our genetic code, dictating which genes are turned on or off, when, and where. These instructions are critical for everything from cell development to how organisms respond to…

Blockchain mining is the process by which transactions are verified and added to a blockchain, primarily in proof-of-work (PoW) systems like Bitcoin. It involves computational work to solve a cryptographic puzzle, ensuring the security and integrity of the blockchain. A key component of this process is finding the nonce, a number that miners adjust to…

The interstellar comet 3I/ATLAS (C/2025 N1), discovered on July 1, 2025, by the NASA-funded ATLAS telescope in Río Hurtado, Chile, is the third confirmed interstellar object to pass through our solar system, following 1I/ʻOumuamua (2017) and 2I/Borisov (2019). Here’s the most current information based on available data up to July 28, 2025: Key Characteristics Orbital…

In the vast archives of astronomical photography lies a mystery that challenges our understanding of what might exist in the skies above Earth. A team of international researchers has undertaken an extraordinary investigation, examining thousands of photographic plates taken in the 1950s—before humanity launched its first artificial satellite—to search for evidence of unidentified objects near…
