@Gargron How about quickly adding quoting so they won’t have an excuse to not join?

Wow, scientists have figured out a way to read brain signals to reproduce what the subject is seeing! https://www.biorxiv.org/content/10.1101/2022.11.18.517004v2

  High-resolution image reconstruction with latent diffusion models from human brain activity
  
  Reconstructing visual experiences from human brain activity offers a unique way to understand how the brain represents the world, and to interpret the connection between computer vision models and our visual system. While deep generative models have recently been employed for this task, reconstructing realistic images with high semantic fidelity is still a challenging problem. Here, we propose a new method based on a diffusion model (DM) to reconstruct images from human brain activity obtained via functional magnetic resonance imaging (fMRI). More specifically, we rely on a latent diffusion model (LDM) termed Stable Diffusion. This model reduces the computational cost of DMs, while preserving their high generative performance. We also characterize the inner mechanisms of the LDM by studying how its different components (such as the latent vector of image Z, conditioning inputs C, and different elements of the denoising U-Net) relate to distinct brain functions. We show that our proposed method can reconstruct high-resolution images with high fidelity in straight-forward fashion, without the need for any additional training and fine-tuning of complex deep-learning models. We also provide a quantitative interpretation of different LDM components from a neuroscientific perspective. Overall, our study proposes a promising method for reconstructing images from human brain activity, and provides a new framework for understanding DMs. Please check out our webpage at . ### Competing Interest Statement The authors have declared no competing interest.

@jimcarroll Don’t forget to look up metamaterials, which are object structures that mimic properties of other materials. That could be as important as the base materials themselves. Here’s one story we wrote on them a few years ago: https://www.fabbaloo.com/2018/01/more-on-3d-printed-metamaterials-a-lot-more

  Last week we posted a story about metamaterials, but it seems there is far more to the story.

  Text to 3D: The Massive Implications of Luma AI's Imagine 3D Technology « Fabbaloo
  
  This week Luma AI announced a new 3D model generation technology, that while crude today, will ultimately dominate in the future.
