Actuation Strategies for Underwater Jet‐Propelled Soft Robots

open access: yesJournal of Field Robotics, Volume 43, Issue 6, Page 3868-3892, September 2026.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Self‐Organized Vascularized Human Liver Spheroids: Serum‐Free Culture Conditions and Use as Tissue Building Blocks

open access: yesSmall, Volume 22, Issue 49, 1 September 2026.
This approach addresses a major challenge in tissue engineering: creating larger, vascularized tissues. Microvascular networks in liver spheroids are developed through self‐organization mediated by mesenchymal stem cells. These spheroids are maintained in serum‐reduced or serum‐free medium and serve as building blocks to form planar tissue layers ...

Mitochondrial Haplotype Shapes the Trajectory of Ovarian Aging in Genetically Heterogeneous Rats

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Using genetically heterogeneous rats carrying divergent mitochondrial haplotypes on a randomized nuclear background, we show that mtDNA variation modifies the rate of ovarian aging. OKC‐HETW ovaries showed bioenergetic deficits, reduced mtDNA copy number, and impaired TFAM–mtDNA binding by 4 months of age, with early fibrosis and immune infiltration ...

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

open access: yesThe FEBS Journal, Volume 293, Issue 17, Page 5340-5362, September 2026.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,
