Scientists mapped non-canonical non-B DNA motifs across the human genome and six ape reference genomes (via the Telomere-to-Telomere project) using long-read sequencing, uncovering enriched motifs in satellite DNA and suggesting these alternative DNA shapes influence replication, transcription, genome stability, and potentially disease.
Mechanical engineer Mark Rober explores the concept of compliant mechanisms, which are single structures that combine the frame, spring mechanism, and trigger of a device. Collaborating with Brigham Young University, Rober designed an ant-sized blaster gun using compliant mechanisms and released the STL files for 3D printing. The design was further scaled down using carbon nanotubes and even self-assembled using DNA structures. While the practical applications are uncertain, compliant mechanisms hold potential for advancements in medical science and miniaturization.
