- A new 3-D-printed prosthetic “Third Thumb” project was shared, demonstrating an extra opposable digit controlled by pressure sensors under the user’s feet (http://www.daniclodedesign.com/thethirdthumb).  
- A pre-print on bioRxiv titled “Response to Editas: Unexpected mutations after CRISPR-Cas9 editing in vivo” was circulated, raising concerns about off-target genomic alterations observed in live-animal CRISPR experiments.  
- Discussion of single-molecule DNA-replication studies revealed that replication forks stop unpredictably and can restart at speeds varying ten-fold, challenging prior assumptions about uniform processivity.  
- A BBC News article on high-resolution diffusion-MRI mapping of human brain wiring was linked, showcasing new connectome-level imaging data.  
- A Hacker News thread featuring a close-up real-time visualization of DNA replication was shared, highlighting stochastic pausing and variable polymerase speeds.
