TL;DR

AI Generated

A research team in California has used AI to design new genetic codes for viruses that successfully replicated and killed bacteria. This breakthrough represents the first generative design of complete genomes, potentially leading to new treatments and advancements in engineered cells. The AI's performance was unexpectedly good, generating viruses with new genes and different arrangements. While this is a significant step towards AI-designed life forms, viruses are not considered alive. The technology could have commercial applications, such as phage therapy for bacterial infections. However, there are concerns about potential misuse of AI in enhancing human pathogens.

DNA ‘cassette tape’ research hints at petabyte-scale cartridges and multi-century lifespan on paper — petabytes-per-meter density possible, but today it writes at kilobytes per hour

Researchers from SUSTech and Shanghai Jiao Tong University have created a DNA cassette tape drive that combines DNA storage with a physical tape-based medium, aiming for petabytes-per-meter density and multi-century lifespan. The system currently writes at kilobytes per hour, with a capacity of over half a terabyte per kilometer. While the prototype shows promise in durability and potential data storage, the slow read-write speeds hinder practical application. The DNA tape is encased in a protective shell for longevity, with estimated shelf life of over 300 years at room temperature. Despite challenges in scaling for commercial use, the project highlights the need for new data storage solutions beyond semiconductor-based memory.

MindsEye's sabotage mission is being slammed as dull and pointless

Build A Rocket Boy accuses individuals of sabotaging MindsEye's launch, spending over €1 million on damaging efforts. The studio integrates the controversy into a new in-game mission, Blacklist, to showcase evidence of sabotage to players. However, reports describe the mission as lackluster and failing to deliver a compelling narrative. Critics attribute the launch issues to internal problems, such as management and design decisions, casting doubt on the sabotage claims. The saga continues as MindsEye's post-launch turmoil unfolds.
