Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

open access: yesExperimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

A Recent Reacceleration of the Local Bubble Revealed by Kinematics of Young Star Associations

open access: yesThe Astrophysical Journal Letters
The low-density region of the interstellar medium where the Sun is located is known as the Local Bubble, a cavity filled with high-temperature and low-density plasma that may be created by a series of supernova (SN) explosions over the past 14 Myr ...

Not All Missing Data are Equal: Choosing the Right Imputation Method for Binary Datasets

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 8, Page 4661-4676, December 2026.
ABSTRACT Missing binary predictors are common in reliability, quality control, and industrial decision systems, yet imputation methods are often chosen by convenience rather than evidence. We conduct a Monte Carlo study comparing mode substitution, sequential hot‐deck, missForest, MICE, and KNN with three neighbourhood sizes under MCAR, MAR, and MNAR ...

Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 10, October 2026.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

A Ticklish Affair: Tickling Impacts Play Features in Bonobos

open access: yesAmerican Journal of Primatology, Volume 88, Issue 10, October 2026.
The image sequences show two mother–offspring tickling interactions in bonobos. (a) A female tickles her son's belly with her hands; he shows a full play face and grasps her finger in a play shelter response. (b) A female tickles her daughter with her mouth; the infant shows a full play face. ABSTRACT Heavy tickling has been reported only in humans and

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1105-1125, October 2026.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

“APPROXIMATE” WIGGLE-MATCH DATING APPLIED TO EARLY AMERICAN MUSEUM OBJECTS

open access: yesRadiocarbon
ABSTRACTWiggle-match dating of tree-ring sequences is particularly promising for achieving high-resolution dating across periods with reversals and plateaus in the calibration curve, such as the entire post-Columbian period of North American history. Here we describe a modified procedure for wiggle-match dating that facilitates precise dating of wooden

Physical controls dominate stream metabolism and carbon cycling over nutrients and stoichiometry

open access: yesLimnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Streams process and transport vast carbon quantities along the aquatic continuum. The balance between processing and downstream export is governed by metabolism, which in turn is regulated by distinct physicochemical controls that vary through space and time.

Yes, and…, Yet: Improvising With Literacy Play to Unsettle a Stuck Place in Science of Reading Classrooms

open access: yesReading Research Quarterly, Volume 61, Issue 4, October/November/December 2026.
ABSTRACT Time for literacy play in early childhood and elementary classrooms is decreasing as Science of Reading mandates require more curricular space. This conceptual paper draws on Scollon's mediated discourse theory to reconceptualize learning to read as a “stuck place”, held in place decade after decade by recurrent mechanisms of discursive ...
