Potential impacts of cable bacteria activity on hard-shelled benthic foraminifera: implications for their interpretation as bioindicators or paleoproxies [PDF]

Biogeosciences
Hard-shelled foraminifera are protists able to build a calcareous or agglutinated shell (called a “test”). Here we study the impact of sediment acidification on calcareous test preservation.

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Cable bacteria, living electrical conduits in the microbial world [PDF]

Proceedings of the National Academy of Sciences, 2019
Microorganisms spend their lives searching for chemical reactants that yield metabolically usable energy, one reactant providing electrons and the other accepting them in a redox reaction. In PNAS, Kjeldsen et al. (1) provide a comprehensive genomic and physiological analysis of bacteria that have evolved an ingenious solution to the persistent problem

Double Helix Structure for Stable Flexural Actuation in Soft Robotics

Advanced Intelligent Systems, EarlyView.
This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Electromicrobiological concentration cells are an overlooked potential energy conservation mechanism for subsurface microorganisms

Frontiers in Microbiology
Thermodynamics has predicted many different kinds of microbial metabolism by determining which pairs of electron acceptors and donors will react to produce an exergonic reaction (a negative net change in Gibbs free energy). In energy-limited environments,

Exosome‐mediated gut–brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives—A narrative review

Animal Models and Experimental Medicine, EarlyView.
The gut–brain axis is a bidirectional communication network between the intestines and brain, mediated by gut microbiota and exosomes, that regulates neuroinflammation, protein aggregation, and neuronal health processes central to neurodegenerative diseases.

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...
