Homeostatic mini-intestines through scaffold-guided organoid morphogenesis

result in stochastically developing tissues with a closed, cystic architecture that restricts lifespan and size, limits experimental manipulation and prohibits homeostasis. Here, by using tissue engineering and the intrinsic self-organization properties of cells, we induce intestinal stem cells to form tube-shaped epithelia with an accessible lumen and a similar spatial arrangement of crypt- and villus-like domains to that in vivo. When connected to an external pumping system, the mini-gut tubes are perfusable; this allows the continuous removal of dead cells to prolong tissue lifespan by several weeks, and also enables the tubes to be colonized with microorganisms for modelling host–microorganism interactions. The mini-intestines include rare, specialized cell types that are seldom found in conventional organoids. They retain key physiological hallmarks of the intestine and have a notable capacity to regenerate. Our concept for extrinsically guiding the self-organization of stem cells into functional organoids-on-a-chip is broadly applicable and will enable the attainment of more physiologically relevant organoid shapes, sizes and functions.
Miniature gut tubes grown in vitro from mouse intestinal stem cells are perfusable, can be colonized with microorganisms and exhibit a similar arrangement and diversity of specialized cell types to intestines in vivo.

So Much More Than Art
Miniature canoes, houses and totems, and human figurines have been produced on the Northwest Coast since at least the sixteenth century. What has motivated Indigenous artists to produce these tiny artworks? Are they curios, toys, art, or something else? So Much More Than Art is a highly original exploration of this intricate cultural pursuit. Through case studies and conversations with contemporary Indigenous artists, Jack Davy uncovers the ways in which miniatures have functioned as crucial components of satirical opposition to colonial government, preservation of traditional techniques, and political and legal negotiation. This nuanced study of a hitherto misunderstood practice demonstrates the importance of miniaturization as a technique for communicating complex cultural ideas between generations and communities, and across the divide that separates Indigenous and settler societies. Most of all, So Much More Than Art is a testament to the cultural resilience of the Indigenous peoples of the Northwest Coast.

Miniature Mindfulness: Finding Spiritual Flow with Warhammer 40,000 Models
Warhammer 40,000 (40k) is the world’s most popular miniature wargame. The game is played with miniatures (small-scale figures made of hard plastic or other materials), which have usually been painted by each individual player. These player–painters typically spend hours in deep concentration painting the models. Drawing on interviews and journal entries from a six-month participant study of 14 painters, this paper explores whether miniature painters achieve a flow state, whether this creates a greater feeling of mindfulness, and how painting impacts their overall mental health. Results from this study indicate that miniature painting is meditative, meaningful, and positive for the participants’ mental health. Using the definition of flow outlined in Mihaly Csikszentmihalyi’s book Optimal Experience: Psychological Studies of Flow in Consciousness (1988), flow is a state of pleasure had when an individual concentrates on a specific task. Csikszentmihalyi, from his research on flow, notes that this state of mind involves both immersion and a sense of transcendence, where the individual temporarily loses a sense of self. This sense of loss of self was explored with an increased attention to the feeling of the body, and situated cognition has been further explored to understand how this connects to painting. While flow is regularly applied to videogame studies, less work has been carried out on this flow state during activities like miniature painting.

The Material Culture of Seventeenth- and Eighteenth-Century Dutch Dollhouses: Replication, Reproduction & Imitation
A number of collector’s cabinets known as pronk or luxury dollhouses were formed in the seventeenth and eighteenth centuries by women in the Netherlands. The present study examines the dollhouse cabinets as exemplars of material culture collections assembled by female collectors. Primary sources give outsized attention to the materiality of these structures, often noting types of substance, quality, and craft. Despite what appears to be a straightforward transcription of the domestic world in miniature, the dollhouses are a multifaceted intersection of authentic materials as well as clever imitations or substitutions. The dollhouse collections are themselves predicated on the notion of reproduction as they replicate the home in small scale. Documents from the period provide a rich source from which to probe the meanings invested in the materiality of these dollhouses as sources of wonder. Economic theory from the period sheds new light on the dollhouses as forums for imitation and novelty, concepts that inform the innovative nature of these collections as it intertwined with issues of multiples and miniaturization.

Dolls' houses : from the V&A Museum of Childhood
Published to accompany a new exhibition, Dolls' Houses presents specially commissioned photography that details the astonishing skill and craftsmanship required to create these homes in miniature scale. This book invites you to take a close-up look at the most interesting and historically significant examples of this absorbing craft, from the exquisite Nuremburg House of 1673, to the brightly coloured twentyfirst century Kaleidoscope House. From lavish country mansions to cozy suburban villas, it explores the houses' fascinating roles as both domestic teaching aids and records of contemporary lifestyle, and gives unique insight into the world of their owners.

Development and Improvement of a Piezoelectrically Driven Miniature Robot
In this paper, we proposed a miniature quadrupedal piezoelectric robot with a mass of 1.8 g and a body length of 4.6 cm. The robot adopts a novel spatial parallel mechanism as its transmission. Each leg of the robot has two degrees of freedom (DOFs): swing and lift. The trajectory necessary for walking is achieved by the appropriate phasing of these two DOFs. A new manufacturing method for piezoelectric actuators was developed. During the stacking process, discrete patterned PZT pieces are used to avoid dielectric failure caused by laser cutting. Copper-clad FR-4 is used as the solder pad instead of copper foil, making the connection between the pad and the actuator more reliable. The lift powertrain of the robot was modeled and the link length of the powertrain was optimized based on the model. The maximum output force of each leg can reach 26 mN under optimized design parameters, which is 1.38 times the required force for successful walking. The frequency response of the powertrain was measured and fitted to the second-order system, which enabled increased leg amplitudes near the powertrain resonance of approximately 70 Hz with adjusted drive signals. The maximum speed of the robot without load reached 48.66 cm/s (10.58 body lengths per second) and the payload capacity can reach 5.5 g (3.05 times its mass) near the powertrain resonance.
