Evaluating vector competence for Yellow fever in the Caribbean

open access: yesNature Communications
The mosquito-borne disease, Yellow fever (YF), has been largely controlled via mass delivery of an effective vaccine and mosquito control interventions. However, there are warning signs that YF is re-emerging in both Sub-Saharan Africa and South America.

Flight of the Future: An Experimental Analysis of Event‐Based Vision for Online Perception Onboard Flapping‐Wing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
A thorough analysis of event‐based vision for flapping‐wing robots is presented, with emphasis on hardware integration, suitability under challenging flight conditions, and real‐time performance. Theoretical and experimental studies demonstrate how these sensors enable robust and efficient onboard perception for ornithopters, thereby advancing autonomy

Harnessing Discrete Differential Geometry: A Virtual Playground for the Bilayer Soft Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
A discrete differential geometry‐based framework is developed to model the mechanics of bilayer structures with asymmetric geometry and material properties. The simulations capture dynamic bending and contact interactions in soft robotic grasping, crawling, jumping, and swimming, demonstrating the framework's versatility for programmable shape morphing

Nanoparticles Functionalized with Polymer Brushes for Gene Delivery

open access: yesAdvanced NanoBiomed Research, EarlyView.
The engineering of the next generation gene delivery vectors requires the precise control of the architecture and physicochemical interactions controlling the transport, targeting, uptake, and release of nucleic acid materials to targeted cells. Polymer brush‐functionalized nanomaterials offer unprecedented control over such design and properties, and ...

Advancing Frontiers in Insect Vector Control

open access: yesAmerican Journal of Public Health and the Nations Health, 1950
INSECT control designed to prevent human disease has been carried on for only half a century-but this short epoch is characterized by an almost incredible range of technical, administrative, and organizational developments. It is regrettable that only a few of those believed to be important in advancing insect control as a public health practice can be

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, EarlyView.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
