Automated Shear Strength Characterization at Micro Scales Based on a Microrobotic System
MicromachinesMechanical properties are critical for characterizing and fabricating advanced materials. While current characterization methods are well-established for the nanoscale and larger millimeter-scale, a significant gap exists in automated testing at the ...

Metalens‐Enabled Twisted Chromatic Dispersion
Advanced Physics Research, EarlyView.We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

CHROMOSOME MICROMANIPULATION [PDF]
The Journal of Cell Biology, 1969 Kinetochore reorientation is the critical process ensuring normal chromosome distribution. Reorientation has been studied in living grasshopper spermatocytes, in which bivalents with both chromosomes oriented to the same pole (unipolar orientation) occur but are unstable: sooner or later one chromosome reorients, the stable, bipolar orientation results,

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

SmartBot, EarlyView.Ionogels dynamically and functionally couple ionic liquids with polymer networks, enabling multiscale programmable deformation and motion under electrical, magnetic, optical, thermal, humidity, and chemical stimuli. This article systematically elucidates the constituent components, structural design, and multiscale actuation mechanisms of ionogel ...

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.ART‐conceived monochorionic twin pregnancies are associated with a higher burden of maternal complications compared with spontaneous conception. While fetal and neonatal outcomes did not differ significantly between groups after adjustment for relevant confounders, ART‐conceived pregnancies showed higher point estimates for several adverse outcomes ...

Immune involvement in neuropsychiatric disorders: Insights from single‐cell transcriptomic studies
Psychiatry and Clinical Neurosciences, EarlyView.Neuropsychiatric disorders pose profound challenges to both research and treatment, largely due to their clinical heterogeneity and the limited understanding of their underlying biological mechanisms. While bulk RNA sequencing (bulk RNA‐seq) has been widely used to study gene expression, it cannot resolve cell‐type‐specific signals or detect rare ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.Food puzzles significantly increased food engagement time in captive golden‐headed lion tamarins (Leontopithecus chrysomelas), with individuals spending three times longer foraging compared to standard food bowls. Grooming and activity levels showed no short‐term changes, though patterns varied across enclosures. These findings highlight puzzle feeders
