In an advance in legume genomics, researchers from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences have produced the first gap-free, telomere-to-telomere (T2T) genome assemblies for two model Medicago species.
Prenatal molecular testing enables early detection of chromosomal and genetic disorders during pregnancy using advanced DNA-based techniques, improving outcomes through timely diagnosis and informed decision-making.
Scientists have discovered that a gene called MUC19, inherited from Denisovans through ancient interbreeding, may have played a vital role in helping Indigenous ancestors adapt as they migrated into the Americas. Found at unusually high frequencies in both modern and ancient populations, the gene likely provided immune advantages against new pathogens. This research highlights how archaic DNA, passed through both Denisovans and Neanderthals, enriched human genetic diversity in ways that still shape us today.
Denisovans, a mysterious human relative, left behind far more than a handful of fossils—they left genetic fingerprints in modern humans across the globe. Multiple interbreeding events with distinct Denisovan populations helped shape traits like high-altitude survival in Tibetans, cold-weather adaptation in Inuits, and enhanced immunity. Their influence spanned from Siberia to South America, and scientists are now uncovering how these genetic gifts transformed human evolution, even with such limited physical remains.
Arrow worms, or chaetognaths, are strange ocean predators that have puzzled scientists for more than a century. They have transparent, torpedo-shaped bodies, sharp grasping spines near their mouths, and sensory structures unlike those of any other animal group. Despite their distinctive look, their place on the evolutionary tree has long been a mystery.
Wild and captive birds are well known as possible carriers of numerous pathogens, and they have recently received scientific attention concerning human health. Mycoplasma spp. Infections have been detected in a variety of wild and captive bird species worldwide.
Cancer remains a leading cause of death globally, driven by complex genetic and molecular alterations. PTPN6, a key regulator of immune response and cell signaling, has shown potential in specific cancers, but its role across multiple cancer types, particularly solid tumors, remains underexplored.
Natural ecosystems are intricate webs where species can interact directly, like predators and prey, or influence one another through a chain of environmental effects. But can these indirect interactions be powerful enough to permanently alter a species' genetic makeup? According to researchers at the Institute of Organismic and Molecular Evolution at Johannes Gutenberg University Mainz (JGU), the answer is a definitive yes.
