Symmetry Is Related to Sexual Dimorphism in Faces: Data Across Culture and Species [PDF]
Summary Background Many animals both display and assess multiple signals. Two prominently studied traits are symmetry and sexual dimorphism, which, for many animals, are proposed cues to heritable fitness benefits.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Sexual Selection in a Brentid Weevil [PDF]
In most insects, differences between the sexes involve not only primary characters necessary for gamete production, copulation, and oviposition, but also sexual structures and behaviors involved in the acquisition of mates. The most striking of these secondary characters, such as exaggerated size, weaponry, or coloration, tend to occur in males, and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

The Handicap Principle in Sexual Selection [PDF]
The theory of the selection of epigamic color, structure and behavior was originally due to Darwin (1874) and was later elaborated by Fisher (1930) and by O'Donald (1962, 1963, 1967). It is well known and is discussed below. An alternative account of this type of sexual selection has been suggested recently by Zahavi (1975).

Pair‐wise comparison of the CellSearch and FETCH enrichment technologies for circulating tumor cells (CTCs) from metastatic breast, prostate, and small cell lung cancer patients shows an increased capture of CTCs using FETCH enrichment. The clinical implementation of circulating tumor cells (CTCs) as a predictive tool for therapy efficacy in the ...

Sexual selection protects against extinction [PDF]
Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring1. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of ...

Primate brain architecture and selection in relation to sex
Background Social and competitive demands often differ between the sexes in mammals. These differing demands should be expected to produce variation in the relative sizes of various brain structures.

The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
