Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

Advanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Targeting Adipose Tissue Function Protects Against Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
This study explores the role adipose tissue (AT) phenotypes have in determining cardiovascular outcomes in an obesity‐related heart failure with preserved ejection fraction (HFpEF) model. Pharmacological induction of thermogenesis promoted resilience to HFpEF‐induced remodeling of AT and conferred cardioprotection. Surgical and genetic models confirmed

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Tendon Organoids Enable Functional Tendon Rejuvenation Through ALKBH5‐Dependent RNA Demethylation

Advanced Science, EarlyView.
FT organoids reverse the aged phenotype of tendon cells, reinstating a fetal‐like state. This breakthrough establishes a potent cell source for tendon tissue engineering, effectively advancing regenerative medicine. ABSTRACT Adult tendon injuries pose a major clinical challenge due to limited self‐repair capacity, resulting in suboptimal regeneration ...
