Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Age and Huddling as Determinants of Metabolic Rate in Grasshopper Mice (Onychomys leucogaster) [PDF]
The metabolic rates of grasshopper mice (Onychomys leucogaster) were determined every third day from birth to adulthood. Metabolic rates were quantitated by measuring oxygen consumption in an open circuit system.

Timescale-invariant representation of acoustic communication signals by a bursting neuron [PDF]
Acoustic communication often involves complex sound motifs in which the relative durations of individual elements, but not their absolute durations, convey meaning.

Tyrosine kinase inhibition produces specific alterations in axon guidance in the grasshopper embryo [PDF]
Tyrosine kinase signaling pathways are essential for process outgrowth and guidance during nervous system development. We have examined the roles of tyrosine kinase activity in programming growth cone guidance decisions in an intact nervous system in ...

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Integrating species distribution models, genetics and morphology to infer species dynamics of New Zealand Phaulacridium grasshoppers : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]
Species comparison studies have used a number of different methods that can contribute to our understanding of processes that influence the differences and similarities observed between species.
