Globally, a positive shift to renewable and sustainable bioenergy usage has been witnessed over the years. An ideal resource should contribute equally to bioeconomy, circular economy and sustainable development. One such less explored resource is an aquatic weed, Pontederia crassipes, commonly known as water hyacinth, which is documented as one of the major invasive aquatic weeds due to its rapid reproduction, capacity to deplete nutrients from water bodies, and adaptation to new habitats.

Chromosomal translocations leading to the fusion of tropomyosin receptor kinases (TRK) with diverse partner proteins have been identified as oncogenic drivers in many adult and pediatric cancers. While first-generation TRK kinase inhibitors, such as entrectinib and larotrectinib, have shown positive responses in TRK fusion-positive cancers, resistance mutations against these inhibitors in the kinase domain limit their efficacy. Second-generation inhibitors are in clinical evaluation, highlighting a need for novel therapeutic modalities to achieve durable suppression of the oncogenic activity of TRK fusions.

Unlabelled: Common activities of daily living naturally blend walking on level ground, stairs, and slopes. Predicting human locomotion behavior across these environments is critical for control design in lower-limb assistive devices. One approach to achieving this goal is to use feedforward simulation of conceptual gait models that capture the whole body dynamics of human locomotion.

Integrin α5β1 is crucial for cell attachment and migration in development and tissue regeneration, and α5β1 binding proteins can have considerable utility in regenerative medicine and next-generation therapeutics. We use computational protein design to create de novo α5β1-specific modulating miniprotein binders, called NeoNectins, that bind to and stabilize the open state of α5β1. When immobilized onto titanium surfaces and throughout 3D hydrogels, the NeoNectins outperform native fibronectin (FN) and RGD peptides in enhancing cell attachment and spreading, and NeoNectin-grafted titanium implants outperformed FN- and RGD-grafted implants in animal models in promoting tissue integration and bone growth.

Prolonged immobilization during long-range aeromedical evacuation (LAE) is vital for stabilizing patients with spinal fractures, spinal cord injuries, and traumatic brain injuries. However, pressure injuries are a significant risk during long periods of immobilization, as continuous high pressure on soft tissues can lead to ulceration. This paper introduces a novel adaptive spine board (ASB) overlay, an air-cell-based support surface, designed to optimize interface pressure redistribution during LAE.

Qubit frequency shifts, which often contain information about a target environment variable, are detected with Ramsey interference measurements. Unfortunately, the sensitivity of this protocol is limited by decoherence. We introduce a new protocol to enhance the sensitivity of a qubit frequency measurement in the presence of decoherence by applying a continuous drive to stabilize one component of the Bloch vector.

Droplet coalescence is ubiquitous in nature, and its regulation is significant in industrial processes and biomedical applications. While bare droplets suddenly coalesce in contact, the droplets covered with liquid-repellent particles to form "liquid marbles (LMs)" are not. Previously, the external stimuli-responsive breakage of the particle layer enables the regulation of the coalescence timing.
