Dream-Cubed Controllable Generative Modeling in Minecraft by Training on Billions of Cubes

When fresh data isn’t available, developers usually turn to “derived” data—either recycling the same text over multiple training rounds (multi-epoch repetition) or rewording it using AI (paraphrasing). To measure how well this works, the researchers introduced a concept called token effectiveness ($\eta$). Think of it as a value score: a completely fresh, original word gets a 1.0, while a repeated or reworded token might score lower depending on how useful it remains to the model.


We introduce, a new large-scale dataset and family of generative models for generating Minecraft worlds at block resolution. Our data comprises billions of high-quality and carefully-balanced cubes from procedurally generated Minecraft terrain and human-authored maps, which we use to study discrete and continuous 3D diffusion models for biome-conditioned chunk generation. When trained with our data, we show that both approaches can generate high-fidelity chunks of the game world, and that the discrete masked diffusion formulation gives us inpainting, outpaining, and user-defined block conditioned generation as a free byproduct of the training objective. This enables players and creators to mold the world around them by generating structures, terrain, and maps that are immediately editable and playable.

Why Minecraft?

Generative AI has made incredible progress in the fields of image, video, and text generation. Despite success in these modalities, the interactive 3D worlds of video games have received much less research attention. We aim to close this gap by releasing a dataset based on one of the most successful and popular video games, Minecraft.

Steam forum ClickFix attacks infect gamers with XMRig cryptominers

Steam discussion forums are being abused in ClickFix attacks that pretend to be fixes for game and computer problems but actually infect devices with cryptominers.

BleepingComputer learned of the campaign from a reader, who told us threat actors are creating random Steam accounts to post what appears to be helpful fixes for people’s posts about games crashing, lost inventory items, and other technical issues.

The threat actors reply to posts, telling other members to open PowerShell as an administrator and run a command to fix the issue. However, when executing the command, it quietly downloads an XMRig miner executable and launches it on the computer.

‘The mid2000s was the golden era of firstperson shooters’: David Szymanski, creator of Dusk and Iron Lung, discusses the games on his PC

David Szymanski, creator of Dusk and one of the chief architects of the retro FPS revival, grew up playing games like Lemmings and Oil’s Well on the family PC. Among these family favourites was a formative first-person game. But it probably isn’t the one you’d expect: “The most foundational one I can remember is playing Myst for the first time,” says the New Blood designer. “That was the first game I remember really getting super into—being able to enter another world and explore it in first-person.”

Initially a designer of short horror games, Szymanski’s breakout came in 2018 with Dusk, an homage to classic ’90s shooters like Doom and Quake. Following Dusk’s success, Szymanski returned to developing shorter games, including the hit submarine horror game Iron Lung, which was adapted into a movie by YouTuber Markiplier earlier this year.

Scientists invent new board games to reveal how we tackle the unknown

Playing board games can be fun, challenging, infuriating and a great way to pass the time. They can also help scientists understand how we solve new problems.

In a study published in the journal Nature, researchers created brand-new strategy games to see how players reason before tackling games they have no experience with. The goal of this research was to see how people react when they are thrown into an unfamiliar situation.

Most previous studies focused on how experts master games they already know or how massive supercomputers calculate millions of moves. What was missing was how everyday people reason about a game before they play it, which could provide insights into how we make quick decisions about situations we’ve never encountered before.

Dead Space creator and Call of Duty veteran Glen Schofield announces retirement: ‘I had a front row seat to one of the greatest creative explosions in history’

The blockbuster veteran said last year he might not make another game.

Biodegradation of polyethylene by the marine fungus Parengyodontium album

Year 2024 Marine fungus that eats plastic.


Plastic pollution in the marine realm is a severe environmental problem. Nevertheless, plastic may also serve as a potential carbon and energy source for microbes, yet the contribution of marine microbes, especially marine fungi to plastic degradation is not well constrained. We isolated the fungus Parengyodontium album from floating plastic debris in the North Pacific Subtropical Gyre and measured fungal-mediated mineralization rates (conversion to CO2) of polyethylene (PE) by applying stable isotope probing assays with 13 C-PE over 9 days of incubation. When the PE was pretreated with UV light, the biodegradation rate of the initially added PE was 0.044%/day. Furthermore, we traced the incorporation of PE-derived 13 C carbon into P. album biomass using nanoSIMS and fatty acid analysis.
