Cells, 2021 Mammals exhibit a tremendous amount of variation in sperm morphology and despite the acknowledgement of sperm structural diversity across taxa, its functional significance remains poorly understood. Of particular interest is the sperm of rodents.

Advanced Science, EarlyView.Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells
Advanced Science, EarlyView.BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

The Sperm Atlas: An open sperm morphology database
, 2023 Sperm morphology is an indicator of individual fertility potential. Population sustainability is dependent on the maintenance of fertility rates at a threshold below which collapse is inevitable. Thus, sperm morphology is a potential barometer for species viability and should be a ubiquitous measure used in conservation efforts.

Serum lipid profiles are associated with semen quality
Asian Journal of Andrology, 2017 We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were

Cryopreservation of common carp sperm [PDF]
, 2003 Experiments were carried out to investigate the effect of five extenders (sucrose, glucose, fructose, KCl and a saline carp sperm extender) and two cryoprotectants (dimethyl-sulfoxide (DMSO) and methanol) on the cryopreservation of common carp sperm ...

A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot
Advanced Science, EarlyView.Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...

Advanced Science, EarlyView.This study identifies that Grtp1 maintains germline redox homeostasis by interacting with PRDX1/4‐TXN to antagonize paternal reproductive aging. Growth hormone restores Grtp1 expression, rectifies aberrant sperm DNA methylation, and ameliorates intergenerational anxiety and social deficits, highlighting the GH‐GRTP1 axis as a promising intervention ...
