Scientists have recently reconstructed the ancestral karyotype of the banana family, revealing how chromosome numbers decreased stepwise from 17 to 9–11 over evolutionary time. The study was led by scientists from the South China Botanical Garden (SCBG) of the Chinese Academy of Sciences (CAS), in collaboration with researchers from Sichuan University and other institutions. The findings were published in Current Biology.

Wind farms have received heat in recent years for their potential to harm wildlife, a notable issue in western North America where some farms are located near populations of protected Bald Eagles (Haliaeetus leucocephalus) and Golden Eagles (Aquila chrysaetos). A new study published in the Journal of Raptor Research titled “Behavioral Responses of Large Soaring Raptors to Audio Deterrents at Commercial Wind-Energy Facilities in the Western USA” found that outfitting turbines with devices that emit warning sounds to approaching raptors can effectively reduce the number of collisions, and therefore deaths, at wind energy sites. For large soaring birds like eagles, hawks, and vultures, this is an especially valuable finding and offers a positive development for a long-standing conservation challenge. 

A recent review in the Chinese Medical Journal highlights how tryptophan metabolism regulates female reproductive health via three pathways—kynurenine, serotonin, and indole. These pathways influence ovarian function, immune regulation, and pregnancy outcomes. The review also proposes potential interventions including diet and microbiota modulation, while noting more research is needed for precise mechanisms and clinical applications.

A large scale study of nearly 700 species reveals the evolutionary relationships and history of Neogastropoda, a diverse group of marine snails. The findings provide new evidence for their single origin, identify four new families and reveal a previously undetected burst of diversification in the early Cenozoic.
