Paying peer reviewers Interview with @danielgorelick.bsky.social about @biologyopen.bsky.social Fast & Fair trial in which peer reviewers were paid £220/review Spoiler: it works - fast, high quality reviews www.nature.com/articles/d41...
nature.com
Why paying peer reviewers works, according to a journal’s editor-in-chief
A biology journal that paid peer reviewers found that the approach cut the time to a first editorial decision by 85% and maintained high-quality reviews.

Further confirmation that high AMH and AFC do not always mean oocyte quality. On the other hand, better ovarian reserve parameters could lead to higher number of mature oocytes, which is associated with higher live birth rates. Fertility is a delicate balance between quality and quantity!!!!!

Wenli Fan et al. leverage conditional mouse knockouts to explore the link between placental problems and congenital heart defects, showing that SLC25A1 regulates trophoblast differentiation and placental development to safeguard embryonic heart formation. 🐭🫀 bit.ly/4g372OU #DevBio
Working model of the impact of Slc25a1 deficiency on placental and embryonic cardiac development. In the normal placenta (left), SLC25A1 facilitates the transport of citrate from mitochondria to the cytoplasm. Citrate is converted into acetyl-CoA, which is essential for maintaining H3K27ac and promoting the differentiation of trophoblast cells. Trophoblast cells secrete PSG proteins, supporting normal placental and embryonic heart development. In the absence of Slc25a1 (right), citrate cannot be transported from mitochondria to the cytoplasm, resulting in a reduction in acetyl-CoA levels. This leads to reduced deposition of H3K27ac at the promoter and enhancer regions of key factors involved in trophoblast differentiation and Psg genes, thereby affecting the expression levels of these genes and causing abnormal placental development, which in turn leads to conotruncal defects and thinner ventricular walls in mouse embryonic hearts.
