Miniaturized multi-sensor loggers provide new insight into year-round flight behaviour of small trans-Sahara avian migrants

Movement Ecology, 2018
Background Over the past decade, the miniaturisation of animal borne tags such as geolocators and GPS-transmitters has revolutionized our knowledge of the whereabouts of migratory species.

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

Flight muscle mitochondria are robust against endurance flight damage in blackpoll warblers Setophaga striata

Journal of Avian Biology
Migratory birds are physiologically challenged by intense exercise while fasting during flights that may last hours to days. Exercise‐induced oxidative stress could compromise flight performance by inducing mitochondrial dysfunction in the flight muscle.

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

Advanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Drone noise differs by flight maneuver and model: implications for animal surveys

Drone Systems and Applications
Drones are becoming a common tool for animal monitoring; however, sound emitted from drones may disturb animals and bias survey results. Understanding noise levels produced by different flight maneuvers, altitudes (i.e., above ground level (AGL)), and ...

Field Experiments With a Wind Tunnel on the Flight Speed of Some West African Mosquitoes (Diptera: Culicidae) [PDF]

, 1981
An open wind tunnel, down which air was blown from over a bait animal, was used in the field in the Gambia to measure the flight speed of host-seeking mosquitoes. Insects were trapped on an electrocuting grid fitted halfway up the tunnel. As the speed of

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...
