Membrane proteins are essential bio-macromolecules involved in numerous critical biological processes and serve as therapeutic targets for a wide range of modern pharmaceuticals. Small amphipathic molecules, called detergents or surfactants, are widely used for the isolation and structural characterization of these proteins. A key requirement for such studies is their ability to maintain membrane protein stability in aqueous solution, a task where conventional detergents often fall short.

Background: The identification of B-cell epitopes (BCEs) is fundamental to advancing epitope-based vaccine design, therapeutic antibody development, and diagnostics, such as in neglected tropical diseases caused by parasitic pathogens. However, the structural complexity of parasite antigens and the high cost of experimental validation present certain challenges. Advances in Artificial Intelligence (AI)-driven protein engineering, particularly through machine learning and deep learning, offer efficient solutions to enhance prediction accuracy and reduce experimental costs.

Alum sludge (AlS) has emerged as an effective adsorbent for anionic contaminants, with traditional activation methods like acid/base treatments and calcination employed to enhance its adsorption capacity. However, these approaches encounter significant drawbacks, including excessive waste generation, structural degradation, and limited efficacy for cationic contaminants. To overcome these challenges, this study proposes electrochemical activation as a sustainable method to enhance alum sludge adsorption performance by generating oxygen-containing functional groups (O-FGs) on its surface.

Membrane proteins play central roles in cell physiology and are the targets of over 50% of FDA-approved drugs. In the present study, we prepared single alkyl-chained triglucosides decorated with multiple pendants, designated multiple pendant-bearing glucosides (MPGs), to enhance membrane protein stability. The new detergents feature two and four pendants of varying size at the hydrophilic-lipophilic interfaces, designated MPG-Ds and MPG-Ts, respectively.

Achieving net-zero emissions by 2050 requires the development of effective negative emission techniques, including ocean-based approaches for CO sequestration. However, the implementation and testing of marine CO removal (mCDR) techniques such as ocean iron fertilization (OIF) or ocean alkalinity enhancement (OAE) face significant challenges. Herein, a novel self-operating electrochemical technology is presented that not only combines OIF and OAE, but also recovers hydrogen gas (H) from seawater, hence offering a promising solution for achieving quantifiable and transparent large-scale mCDR.
