Nap Pods
Nap pods also known as sleep pods, napping pods or nap capsules are special types of structures or chairs, often used in corporate/ workplace environments, hospitals and universities, that allow people to nap. Users use the pods to take private sleep breaks, often aided by technology and ambient features. Nap pods have emerged in corporate environments, hospitals, universities, airports and other public places. Their supposed efficacy is rooted in research that suggests that 20-minute naps could reduce signs of fatigue, boost energy levels, improve focus, boost productivity, improve mood, enhance learning, reduce stress and reduce the risk of cardiovascular disease.

Vertebrate Cutaneous Sensory Corpuscles
Vertebrate cutaneous sensory corpuscles are specialized sensory nerve formations located in the skin of all vertebrates and responsible for tactile sensation. Functionally, they are mechanoreceptors transducing external mechanical stimuli into electrical signals which will be later led to the Central Nervous System. The afferent innervation of vertebrate skin is supplied by nerve fibers (Aβ, Aδ, C) which are originated from peripheral neurons localized in the dorsal root ganglia (DRG). Aβ nerve fibers end at the dermis level forming several morphotypes of sensory corpuscles with capacity of detecting different stimuli: Merkel cell–neurite complexes, Ruffini corpuscles, Meissner’s corpuscles and Pacinian corpuscles are present in the glabrous skin; while pilo-neural complexes are found in hairy skin. The structure of sensory corpuscles is formed by an axon, non-myelinating Schwann-like cells, a capsule of endoneurial and/or perineurial origin and extracelullar matrix molecules.  The vertebrate skin contains sensory corpuscles that are receptors for different qualities of mechanosensitivity like light brush, touch, pressure, stretch or vibration. These specialized sensory organs are linked anatomically and functionally to mechanosensory neurons, which function as low-threshold mechanoreceptors connected to peripheral skin through Aβ nerve fibers. Furthermore, low-threshold mechanoreceptors associated with Aδ and C nerve fibers have been identified in hairy skin. The process of mechanotransduction requires the conversion of a mechanical stimulus into electrical signals (action potentials) through the activation of mechanosensible ion channels present both in the axon and the periaxonal cells of sensory corpuscles (i.e., Schwann-, endoneurial- and perineurial-related cells). Most of those putative ion channels belong to the degenerin/epithelial sodium channel (especially the family of acid-sensing ion channels), the transient receptor potential channel superfamilies, and the Piezo family.

Cook-Medley Hostility Scale
The Cook-Medley Hostility Scale (Ho) is a standard in psychology designed to measure an individual's personality and temperament, specifically degrees of hostility. Initially developed as a scale for the Minnesota Multiphasic Personality Inventory (MMPI), scores from the hostility scale represent the individual's disposition towards cynicism and chronic hate. Scores from the scale have been used by studies as a predictor of the measured individual's risk of developing certain health problems as well as the success of their interpersonal relationships. Published by Walter W. Cook and Donald M. Medley in 1954, the scale has found extensive applications in defining hostility and aggression as a potential factor contributing to health and mortality. The scale's validity and reliability as a diagnosis, however, is still considered with a certain degree of controversy.

Fundamentalism
Fundamentalism usually has a religious connotation that indicates unwavering attachment to a set of irreducible beliefs. However, fundamentalism has come to be applied to a tendency among certain groups – mainly, although not exclusively, in religion – that is characterized by a markedly strict literalism as it is applied to certain specific scriptures, dogmas, or ideologies, and a strong sense of the importance of maintaining ingroup and outgroup distinctions, leading to an emphasis on purity and the desire to return to a previous ideal from which advocates believe members have strayed. Rejection of diversity of opinion as applied to these established "fundamentals" and their accepted interpretation within the group often results from this tendency. Depending upon the context, the label "fundamentalism" can be a pejorative rather than a neutral characterization, similar to the ways that calling political perspectives "right-wing" or "left-wing" can have negative connotations.

Chronic Vestibular Syndromes including PPPD and MdDS
Overall, the clinical spectrum of vestibular migraine (VM) is broad, with patients describing a range of dizziness symptoms, accompanying symptoms and duration of attacks. When dizziness symptoms become more prolonged, they merge with other chronic vestibular syndromes such as persistent postural-perceptual dizziness (PPPD) and mal de débarquement syndrome (MdDS).

ARP2/3 Complex-Driven Actin Polymerization in RSV Infection
Respiratory syncytial virus (RSV) is the leading viral agent causing bronchiolitis and pneumonia in children under five years old worldwide. The RSV infection cycle starts with macropinocytosis-based entry into the host airway epithelial cell membrane, followed by virus transcription, replication, assembly, budding, and spread. It is not surprising that the host actin cytoskeleton contributes to different stages of the RSV replication cycle. RSV modulates actin-related protein 2/3 (ARP2/3) complex-driven actin polymerization for a robust filopodia induction on the infected lung epithelial A549 cells, which contributes to the virus’s budding, and cell-to-cell spread.

Photoprotection of Vanilla Orchid
Vanilla orchid is a shade-loving plant that is very sensitive to high radiation. We found that blue light treatment can induce photoacclimation and enhances vanilla orchid acquired photoprotection. Blue light induces chloroplast avoidance, increases antioxidant enzyme activities, and enhances photosynthesis rate when vanilla orchid is exposed to high light stress. This study found that acclimating vanilla orchid with blue light before transplantation to the field might eliminate photoinhibition and enhance vanilla growth and production.

Spousal Privilege
In the common law, spousal privilege (also called marital privilege or husband-wife privilege) is a term used in the law of evidence to describe two separate privileges that apply to spouses: the spousal communications privilege and the spousal testimonial privilege. Both types of privilege are based on the policy of encouraging spousal harmony and preventing spouses from having to condemn, or be condemned by, their spouses: the spousal communications privilege or confidences privilege is a form of privileged communication that protects the contents of confidential communications between spouses during their marriage from testimonial disclosure, while spousal testimonial privilege (also called spousal incompetency and spousal immunity) protects the individual holding the privilege from being called to testify in proceedings relating to his/her spouse. However, the spousal privileges have their roots in the legal fiction that a husband and wife were one person.

Human Satellite DNA Families
Going back to the 1960s, the discovery and classification of three clearly distinguishable human genomic DNA fractions in CsSO4 gradients established the identity of the corresponding classical satellite DNAs I, II, and III. More precisely, a set of repetitive sequences with analogous buoyant densities was found to compose each gradient fraction. These DNA fractions presented a characteristic inter-sequence heterogeneity, which led to a new classification in 1987, as a prime family of simple repeats was identified for each fraction. The three families were described as satellite DNA families I, II, and III and were first reported to be present in all acrocentric chromosomes, as well as in chromosomes 3 and 4. Additionally, the centromeric alpha (α) satellite DNA family was also identified and described, soon becoming the most intensively studied human satDNA sequence. Later on, gamma (γ) and beta (β) satellites were likewise found among the diverse families of human satellite DNAs.

Supercritical Antisolvent Technique for the Preparation of Nanocatalysts
In an era where sustainability is becoming the main driving force for research and development, supercritical fluids-based techniques are presented as a very efficient alternative technology to conventional extraction, purification, and recrystallization processes. Supercritical antisolvent (SAS) precipitation is a novel technique that can replace liquid antisolvent precipitation techniques. Additionally, through the optimization of precipitation operating conditions, morphology, particle size, and particle size distribution of nanoparticles can be controlled. As an antisolvent, supercritical carbon dioxide (scCO2) is far more sustainable than its conventional liquid counterparts; not only does it have a critical point (304 K and 73.8 bar) on its phase diagram that allows for the precipitation processes to be developed so close to room temperature, but also its recovery and, consequently, the precipitated solute purification stage is considerably simpler. This technique can be used efficiently for preparing nanocatalysts to be used in biodiesel production processes.
