The biological impacts of the Fukushima nuclear accident on the pale grass blue butterfly
TLDR
It is concluded that artificial radionuclides from the Fukushima Nuclear Power Plant caused physiological and genetic damage to the pale grass blue Zizeeria maha, a common lycaenid butterfly in Japan.

TLDR
Wing-wide elemental patterns of various nymphalid butterflies are examined and it is confirmed that wing-wide color patterns are composed of the border, central, and basal symmetry systems.
Phenotypic plasticity in the range-margin population of the lycaenid butterfly Zizeeria maha
TLDR
The results support the notion that the outbreak of the modified phenotypes in the recent range-margin population was primed by the revelation of plastic phenotype in response to temperature stress and by the subsequent genetic process in the previous range- margin population, followed by migration and temporal establishment of genetically unstable founders in the recently range margins.
The Fukushima nuclear accident and the pale grass blue butterfly: evaluating biological effects of long-term low-dose exposures
TLDR
The pale grass blue butterfly Zizeeria maha is vulnerable to long-term low-dose internal and external exposures; however, insect cells are known to be resistant to short-term high-dose irradiation.
Availability of short amino acid sequences in proteins
TLDR
Frequency distributions of all possible combinatorial sets of three, four, and five amino acids have been examined in the nonredundant protein database, suggesting that information on three‐dimensional structures and functions of proteins exists in the context of connections of short constituent sequences, and that proteins are composed of evolutionarily selected constituent sequences which are reflected in their availability differences in the database.
Word Decoding of Protein Amino Acid Sequences with Availability Analysis: A Linguistic Approach
TLDR
This study confirmed that the English language highly likely follows Zipf's law, a special case of power law, and found that the rank-frequency plot of SCSs in proteins exhibits a similar distribution when low-rank tails are excluded.
Color-Pattern Analysis of Eyespots in Butterfly Wings: A Critical Examination of Morphogen Gradient Models

TLDR
Results indicate that each eyespot ring has independence and flexibility to a certain degree, which is less consistent with the single-morphogen model.
Odorant receptor expression in the mouse cerebral cortex.
TLDR
Data showed that at least a few odorant receptors are expressed not only in olfactory sensory neurons but also in pyramidal neurons in the cerebral cortex, possibly playing an important role either in chemical detection of exogenous or endogenous ligands or in a developmental process such as axon guidance and target recognition.
