- A Nature paper describes a DNA-origami rotary ratchet motor that generates ≈10 pN·nm of torque—about one-fifth of F1F0-ATPase—and dissipates ≈62 kBT s⁻¹, raising the question of whether the AC electric field used to drive it would disturb concurrent biological processes such as DNA synthesis.  
- The Internet Archive is seeking summary judgment in its federal lawsuit with major publishers over controlled digital lending, highlighting the tension between open access and copyright enforcement.  
- Rockwell’s “integrated brain plan” and an associated cognitive-confluence diagram were shared as large-scale visual roadmaps for whole-brain emulation and neurotechnology development.  
- A PMC paper on hippocampal prostheses shows that electrode-recorded “codes” from trained rats can be replayed to untrained rats, enabling them to perform memory tasks without prior learning.  
- Koniku’s “smell cyborg” chip couples 640 electrodes with 128 active and ~50 000 “hidden” cultured neurons to create autonomous olfactory biosensors, positioning the device as an early step toward general-purpose brain–computer interfaces.  
- A DALL·E 2 prompt-book (v1.01) was circulated as a practical guide for leveraging state-of-the-art text-to-image generation.
