Overcoming Transmission Barriers: A Dual‐Functional Adhesive Hydrogel for Direct Monkeypox Virus Neutralization and Wound Healing

Advanced Science, EarlyView.
MPXV infection leads to persistent viral replication and severe local inflammation, while existing treatments cannot simultaneously remove viruses and repair injured tissue. This study constructs Polymer@mPDA@Gel hydrogel via a two‐step hierarchical assembly method: mPDA anchors photothermal polymers to form antiviral photothermal subunits, which are ...

Community structure and dietary pathways for invertebrates on intertidal coral reef flats

, 2015
Intertidal reef flats cover extensive inshore areas of coral reef ecosystems but their contribution to coral reef food webs remains largely unknown.

Toward Material‐Specific Peptides From in Silico Guided Peptide Engineering to Target PET in the Presence of PS

Advanced Science, EarlyView.
This work presents a computational–experimental strategy to engineer material‐binding peptides toward polymer specificity. Molecular dynamics simulations identified residues driving polystyrene binding, enabling targeted substitutions that greatly reduced polystyrene affinity while preserving PET binding.

Predicting missing links in food webs using stacked models and species traits

Nature Communications
Networks are a powerful way to represent the complexity of large ecological systems. However, most ecological networks, such as food webs, contain only partial lists of species interactions.

Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

Advanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Spatial aspects of food webs

, 2005
Spatial distributions of trophic interactions define the spatial heterogeneity of food webs and differences between local and macroecological food webs.

Hydraulic Pressure‐Programmed Molecular Transport in Tough Hydrogels

Advanced Science, EarlyView.
Hydraulic pressure is introduced as a programmable parameter for regulating molecular transport in tough hydrogel membranes. Reversing the pressure direction accelerates or slows transport, tuning characteristic transport times over a 65‐fold range while achieving molecular separation and controlled delivery.

Bioaccumulation of mercury in invertebrate food webs of Canadian Rocky Mountain streams

, 2016
Methylmercury (MeHg) is a contaminant of concern because of its ability to biomagnify in aquatic food webs, resulting in potentially harmful concentrations in higher consumers.

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Nanoplastics rewire freshwater food webs

Communications Earth & Environment
The accelerating use of plastics worldwide is of societal concern, especially as plastics fragment into smaller, micro- and nano-sized particles. Of particular importance is the effects on aquatic ecosystems since a major part of the nanoplastics ...
