Multiple sex chromosomes usually arise from chromosomal rearrangements which involve ancestral sex chromosomes. There is a fundamental condition to be met for their long-term fixation: the meiosis must function, leading to the stability of the emerged system, mainly concerning the segregation of the se...
depending also on the cutoff adopted for the initial magnetic spectrum. in the helical case, the quasi-conservation of the magnetic helicity implies, apart from logarithmic corrections and a factor proportional to the initial fractional helicity, power-like evolution laws equal to those in the non-...
To study the spatial interactions among cancer and non-cancer cells1, we here examined a cohort of 131 tumour sections from 78 cases across 6 cancer types by Visium spatial transcriptomics (ST). This was combined with 48 matched single-nucleus RNA sequen
Life is a chemical reaction. Three major transitions in early evolution are considered without recourse to a tree of life. The origin of prokaryotes required a steady supply of energy and electrons, probably in the form of molecular hydrogen stemming fro
The nutrient-rich tubers of the greater yam, Dioscorea alata L., provide food and income security for millions of people around the world. Despite its global importance, however, greater yam remains an orphan crop. Here, we address this resource gap by p

Syncarpea from the Big-bracted group (BB) and subgen. Kraniopsis from the BW group. The former is missing C. multinervosa, closely related to C. kousa Hance, and C. elliptica (Chun) Q. Y. Xiang & Bouf- ford, closely related to C. capitata Wall. Subgenus Kraniopsis consists of ...
the tribe Camelineae and the allohexaploidCamelina sativa(L.) Crantz. (2n = 40), also known as false or wild flax, German sesame, gold-of-pleasure, or linseed dodder [35,36,37]. This interest was restored due to biofuel or jet fuel potential of the oil from the seeds ofCamelina...
Further, he suggested that research should shift from more theoretical model-building work to empirical inquiries into actual changes in complexity offering several avenues for future research. Unfortunately, such a shift has not yet taken place. Rather, it seems that the interest among evolutionary ...
A decisive event in the evolution of mammals from synapsid reptiles was the modification of ventral thoracic–abdominal epidermal glands to form the mammary gland. The natural selection events that drove the process may have been the provision of certain immunological agents in dermal secretions of ...
