Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge
Advanced Materials Technologies, EarlyView.This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Supplemental Thyroid Hormones and Hatchability of Turkey Eggs
Poultry Science, 1985 Fertile turkey eggs were injected with thyroid hormones to test the effects of exogenous hormones on hatchability. Physiological doses of thyroxine (T4) and triiodothyronine (T3) of 50 and 25 ng, respectively, injected at setting, depressed hatchability.

Weight and Hatchability of Turkey Eggs
Poultry Science, 1938 Abstract EGGS from turkeys whose eggs averaged from 84–89 grams in weight, about the modal egg weight for the material reported, were reported by Marble and Margolf (1936) to have higher hatchability than eggs from females whose eggs averaged less than 84 or more than 89 grams.

Advanced Science, EarlyView.This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

The Effect of Broiler Breeder Strain and Parent Flock Age on Hatchability and Fertile Hatchability
International Journal of Poultry Science, 2010 The effect of genetic strain (Ross 308; Cobb 500) and parent flock age (Ross at 32 and 36 weeks; Cobb at 26 and 44 weeks of age) on hatchability, fertile hatchability, Egg Weight Loss (EWL) and egg break out analysis were examined. At each flock age, 300 eggs from each treatment group were incubated.

Effect of Mercurial Ointment on Hatchability
Poultry Science, 1933 Abstract A CONVENIENT method of ridding hens of body lice is the application of mercurial or blue ointment, a method advocated by Pearl, Surface, and Curtis (1915). The ointment is applied by rubbing three pieces, about the size of a small pea, one underneath each wing and the vent.

Advanced Science, EarlyView.We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Relationship Between Age, Fecundity and Hatchability
Poultry Science, 1934 Abstract AS WAS so aptly stated by Jull (1932) “the inheritance of the ability to lay well over a period of years is of immense practical importance and is deserving of much more consideration than it has received up to the present.” If the trait of continued high egg production through several years (longevity) can be bred into a flock, just to that
