Achieving microecological balance is a complex environmental challenge. This is because the equilibrium of microecological systems necessitates both the eradication of harmful microorganisms and preservation of the beneficial ones. Conventional materials predominantly target the elimination of pathogenic microorganisms and often neglect the protection of advantageous microbial species.

Using ab initio based molecular dynamics and electronic structure calculations, we show that Zn impurities in hydrated amorphous calcium carbonate (ACC) have a much lower coordination number than other divalent impurities due to covalent interactions between the 3d Zn shell and the oxygen atoms of the carbonate and water groups. The local structure around Zn in ACC, including the predicted low coordination number, is confirmed by X-ray absorption spectroscopy of synthetic Zn-bearing ACC. The strong Zn-O chemical interaction leads to substantial water dissociation and slightly disrupts the hydrogen bonding network.

Background: Current guidelines for screening glucose dysregulation (GD) in patients with transfusion-dependent thalassemia (TDT) recommend an annual 2-hour oral glucose tolerance test (OGTT) starting at the age of 10 years.
Objective: Assessment of adherence to OGTT screening in patients with TDT.
Methods: A questionnaire was distributed to 18 Thalassemia Centers in 10 different countries, targeting factors influencing adherence to annual OGTT screening in specialized multidisciplinary pediatric and adult TDT units and identifying strategies to improve adherence to OGTT in TDT patients.

With the rapid expansion of wireless networks, the deployment and long-term maintenance of distributed microwave terminals have become increasingly challenging. To address these issues, we present a bio-inspired microwave system to constitute passive and maintenance-free wireless networks. Drawing inspiration from vertebrate skeletons and skins, we employ stimuli-responsive polymer with tunable stiffness to support and protect sensitive electromagnetic structures, and synthesize self-healable skin-like polymer for system encapsulation.

Although locomotor CPGs have been extensively characterized, it remains unknown how the neuronal populations composing them interact to generate adaptive rhythms. We explored the non-linear cooperation dynamics among the three main populations of ipsilaterally projecting spinal CPG neurons - V1, V2a, V2b neurons - in scratch reflex rhythmogenesis.
