Isotopically Selected Co‐Doping of 121Sb and 123Sb Pairs in Silicon

Advanced Materials, Volume 38, Issue 18, 25 March 2026.
Pairs of 121Sb and 123Sb atoms are doped into silicon using single cluster implantation and found to reside substitutionally within the crystal lattice due to self‐annealing with a Sb‐to Sb separation of ≈2 nm. Molecular dynamics simulations reproduce the observed experimental results and single ion cluster detection efficiencies of 94% are ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Wing and Pappus Appendages Decrease Seed Terminal Velocity: A Meta‐Analysis

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This meta‐analysis integrated terminal velocity records for 1479 species from various sources and explored descriptive patterns by taxonomic group, seed dispersal vector, and seed appendage type. This study revealed that wing and pappus appendage decrease seed terminal velocity with a robust analysis using regression models to predict terminal velocity.

Physical Characteristics of Fast Roping in British Elite Law Enforcement Officers

European Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT Elite law enforcement and special forces operators around the world have a unique skill set, including some risky methods of entry into a scene of operation. With fast roping being actively utilized by this population, it is important to gain an understanding of the physical demands of the task.
