Modulating the fatty acid composition of black soldier fly larvae via substrate fermentation.

Black soldier fly larvae (BSFL, Hermetia illucens) contain high amounts of proteins and essential amino acids and are therefore an appropriate feed source. However, they lack essential fatty acids (FAs), specifically ω-3 and ω-6, making them a less desirable feed choice for aquaculture. The aim of this study was to increase the ω-3 and ω-6 FA concentrations in BSFL by manipulating the FA composition in their rearing substrate.

Optimizing the Rheological and Textural Properties of Chapatti Enriched with House Crickets () Flour Using Hydrocolloids by an I-Optimal Design.

The fortification of food with edible insect flour can improve its nutrition profile, but also affect its techno-functional characteristics. In this study, an I-optimal design was applied to improve the rheological and textural properties of wheat flour chapatti containing 10% cricket () flour. More specifically, the impact and optimal addition of hydrocolloids (carboxymethyl cellulose, hydroxypropyl methylcellulose, guar gum and xanthan gum) and water content were studied.

Laboratory evidence of magnetic reconnection hampered in obliquely interacting flux tubes.

Magnetic reconnection can occur when two plasmas, having anti-parallel components of the magnetic field, encounter each other. In the reconnection plane, the anti-parallel component of the field is annihilated and its energy released in the plasma. Here, we investigate through laboratory experiments the reconnection between two flux tubes that are not strictly anti-parallel.

Enhancement of the Nonresonant Streaming Instability by Particle Collisions.

Streaming cosmic rays can power the exponential growth of a seed magnetic field by exciting a nonresonant instability that feeds on their bulk kinetic energy. By generating the necessary turbulent magnetic field, it is thought to play a key role in the confinement and acceleration of cosmic rays at shocks. In this Letter we present hybrid-particle-in-cell simulations of the nonresonant mode including Monte Carlo collisions, and investigate the interplay between the pressure anisotropies produced by the instability and particle collisions in the background plasma.
