How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

open access: yesAdvanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

open access: yesAdvanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

open access: yesAdvanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Potential of Aedes aegypti populations in Madeira Island to transmit dengue and chikungunya viruses

open access: yesParasites & Vectors, 2018
Background Aedes spp. mosquitoes mainly transmit the arboviruses dengue virus (DENV) and chikungunya virus (CHIKV) in urban areas, causing a severe public health problem. In 2012–2013, a major dengue outbreak occurred on Madeira Island where the mosquito
