Some unique asexual species persist over time and contradict the consensus that sex is a prerequisite for long-term evolutionary survival. How they escape the dead-end fate remains enigmatic. Here, we generated a haplotype-resolved genome assembly on the basis of a single individual and collected genomic data from worldwide populations of the parthenogenetic diploid oribatid mite to identify signatures of persistence without sex.

Despite numerous studies on the rise and fall of terrestrial megafauna in the late Quaternary, knowledge about marine megafauna from this period remains limited. In this study, we performed radiocarbon dating and partial mitochondrial DNA sequencing from the skeletal remains of three species of small odontocetes (Pacific white-sided dolphins, Dall's porpoises and harbour porpoises) excavated from prehistoric archaeological sites around the Japanese shore dating back to 8500-1000 years ago (ya). Pacific white-sided dolphins that habituated the eastern coast of Hokkaido around 2000 ya belonged to different maternal groups than those from over 5000 ya and today.

Fibromyalgia (FM) is a common chronic pain with no established treatment. Acupuncture is an expected treatment for FM though a diagnosis of FM tends to be delayed, and the advantage is still unclear in early-phase intervention with acupuncture treatment for FM. A 51-year-old woman with panic disorder presented with a four-month history of whole-body pain and was diagnosed with FM.

The genus is widely distributed, primarily in East Asia. is located at the northern limit of this genus distribution, and understanding changes in its distribution is crucial for understanding the evolution of plants in this region, as well as their relationship with geological history and climate change. Moreover, the classification of sect.

The Japanese Archipelago consists of a series of isolated yet interconnected islands off the Eurasian continent. The linear topography of the archipelago presents a unique biogeographic context for the dispersal of organisms from the continent. In this study, mitochondrial DNA (mtDNA) and single-nucleotide polymorphism (SNP) variation were employed to elucidate the dispersal history of the Japanese clouded butterfly (Parnassius glacialis) across the Japanese Archipelago, including the northern island (Hokkaido), the main island (Honshu), and Shikoku Island.
