In their shapes, molecules of some bipolar metabolites resemble the so-called bola, a hunting weapon of the South American inhabitants, consisting of two heavy balls connected to each other by a long flexible cord. Herein, we discuss the structures and properties of these natural products (bola-like compounds or bolaamphiphiles), containing two polar terminal fragments and a non-polar chain (or chains) between them, from archaea, bacteria, and marine invertebrates. Additional modifications of core compounds of this class, for example, interchain and intrachain cyclization, hydroxylation, methylation, etc.

Microcontaminants (MCs) and microplastics (MPs) originating from the textile sector are today receiving a great deal of attention due to potential environmental concerns. Environmental pressures and impacts related to the textile system include not only the use of resources (, water) but also the release of a wide variety of pollutants. This review's main objective is to highlight the presence of textile MCs and MPs in water, in their full path from textile factories (from raw materials to the final product) to wastewater treatment plants (WWTPs), and finally to the receiving surface waters.

To date, various kinds of memristors have been proposed as artificial neurons and synapses for neuromorphic computing to overcome the so-called von Neumann bottleneck in conventional computing architectures. However, related working principles are mostly ascribed to randomly distributed conductive filaments or traps, which usually lead to high stochasticity and poor uniformity. In this work, a heterostructure with a two-dimensional WS monolayer and a ferroelectric PZT film were demonstrated for memristors and artificial synapses, triggered by in-plane ferroelectric polarization.

Median mandibular cyst is defined as an odontogenic cyst in a rare midline location. In spite of this definition, there have been two reports of a peculiar lesion, so-called "ciliated" median mandibular cyst associated with vital teeth, the origin of which cannot be explained in terms of odontogenic epithelium multipotentiality. We describe a thorough profile of an additional example.

All throughout the so-called "Global South", hundreds of millions of individuals from entire communities in the rural, poorer, or most peripheral areas are not officially recorded by the States they are citizens of or they habitually reside in. This is why several of such States are resorting to extensive and purportedly "universal" digital remote onboarding programs, pioneered by India's Aadhaar, whereby individuals are centrally recorded onto a public database with their identity (and possibly citizenship) confirmed. Whenever paper documents are obsolete, inaccurate, deteriorated, or inexistent, individuals may have their identity confirmed through an "introducer", who mediates between marginalised communities and central authorities and is entrusted by both with this delicate task.
