A purple-pigmented (purple) rice seeds containing an anthocyanin, a major class of flavonoids, and their isogenic non-pigmented (white) seeds were exposed outside of the international space station (ISS) to evaluate the impact of anthocyanin on seed viability in space. The rice seeds were placed in sample plates at the exposed facility of ISS for 440 days, with the bottom layer seeds exposed to space radiation and the top layer seeds exposed to both solar light and space radiation. Though the seed weight of both purple and white seeds decreased after exposure to outer space, growth percentages after germination of purple and white seeds in the top layer were 55 and 15 %, respectively, compared to those in the bottom layer 100 and 70 %, respectively.

s: This study aimed to prepare a new separation medium, silane coupling agent KH570- modified halloysite nanotube (MPS-HNT) monolithic column, with excellent separation performance for small molecular compounds and macromolecular proteins. This was prepared using the principle of redox polymerization with modified HNTs as monomers. The optimal monomer proportion was obtained by optimizing the ratio of monomer, cross-linker, and pore-forming agent, which was evaluated using scanning electron microscopy, nitrogen adsorption, and mercury intrusion.

Objective: Reference intervals for hematologic and clinical chemistry values are useful when diagnosing a pathologic condition in animals. This study establishes relevant reference intervals for six species of wild birds that are frequently rescued at wildlife rescue centers in the Republic of Korea.
Methods: Forty-two Eurasian eagle owls (), 34 Oriental turtle doves (), 73 domestic pigeons (), 27 brown hawk-owls (), 76 common kestrels (), and 25 Eurasian magpies () were included in this study.
Feedback on Escape Behavior of Birds Under Different Hunger Pressure.

College of Life Sciences, Guizhou University Guiyang Guizhou China.
The risk of predation has always been a significant impact on wild birds. Birds, facing with limited energy, must balance their investment between foraging and vigilance. There were currently limited understandings of the vigilant behavior feedback of birds under different hunger pressure.

The aircraft can experience complex environments during the flight. For the random actions, the traditional Gaussian white noise assumption may not be sufficient to depict the realistic stochastic loads on the wing structures. Considering fluctuations with extreme conditions, Lévy noise is a better candidate describing the stochastic dynamical behaviors on the airfoil models.
