A Magnetically Transformable Twisting Millirobot for Cargo Delivery at Low Reynolds Number
Advanced Intelligent Systems, EarlyView.Herein, a soft millirobot, TwistBot, that transforms from a flat shape to a helical shape to propel in fluids at low Reynolds number is reported. Its geometry is optimized by numerical simulation and validated by experiments to effectively propel and deliver solid cargos.

Intestinal Atresia in PPP1R12A‐Related Urogenital and Brain Malformation Syndrome
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT PPP1R12A‐related urogenital and brain malformation syndrome (UBMS) is a newly described disorder characterized by congenital anomalies primarily involving the urogenital system and the brain. We describe a preterm female neonate with multiple congenital anomalies, including type IIIb jejunal atresia, incomplete intestinal rotation, imperforate

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation [PDF]
, 2005 An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another.
