Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

A Soft Robotic Jellyfish with Decoupled Actuators for Agile 3D Locomotion
This study presents a soft robotic jellyfish featuring a functionally decoupled actuation architecture. By separating propulsion, steering, and vertical regulation into independent modules, the robot overcomes conventional coupled‐motion limitations. Utilizing a passive‐valve‐based differential drag strategy and lateral water jets, it achieves agile 3D

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

3D‐Printed Shark‐Inspired Soft–Hard Hybrid Underwater Robot With Buoyancy Control and Onboard Vision
A fully self‐contained shark‐inspired underwater robot is developed using 3D‐printed soft–hard hybrid structures, servo‐driven propulsion, and pump‐based buoyancy control. The platform achieves three‐dimensional locomotion and onboard vision‐based target tracking, offering a reproducible and accessible framework for biomimetic underwater robot research.

Electrostatic Actuation Induces Competing Adhesion and Vibration Regimes at Fingertip Contact
Electric fields modulate fingertip–surface contact to create artificial touch sensations. The mechanisms underlying electrostatic friction, however, remain unclear. Direct imaging and friction measurements under oscillating electric fields showed that adhesion dominates at high frequencies, while vibration contributes substantially at the lower ...

Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups
Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Racism and racial disparities in firearm violence: A scoping review
Abstract Firearm violence (i.e., interpersonal, police firearm violence) disproportionately affects racially minoritized communities. Researchers recently shifted their focus from race to racism to better understand the factors that contribute to racial disparities in firearm violence.
