DNA analysis of the Dragon Man skull has confirmed it as a Denisovan, providing the first clear physical link to this elusive human species and revealing their physical traits, geographic range, and genetic influence on modern humans, especially in Asia.
Scientists from ARS and University of Florida have made a genetic discovery that could accelerate the development of hybrid citrus trees tolerant to citrus greening disease and capable of producing orange-like fruit ideal for juice production. The discovery involves identifying a master gene and creating a DNA marker for it, enabling breeders to screen seedlings for desired flavor profiles at an early stage. This research represents a significant step in citrus breeding and could serve as a model for other crop improvement programs.
A study led by researchers at ETH Zurich used young bulls to investigate genes active in different reproductive tissues, discovering a large number of genes associated with fertility in bulls that are likely relevant to male fertility in humans. The findings could lead to better diagnostics for identifying genes and variants in breeding bulls, benefiting livestock breeders by minimizing financial losses from failed artificial inseminations. The research also sheds light on the importance of using suitable animal models for male fertility studies, as bulls provide a unique opportunity for comprehensive analysis compared to human subjects.
Scientists have discovered a new species of protist, Oligohymenophorea sp. PL0344, in a pond at Oxford University Parks, which has a unique divergence in its genetic code. Unlike other organisms, this protist translates the stop codons TAA and TAG into two different amino acids, breaking the previously known rules of gene translation. The discovery could inspire future genetic discoveries and highlights the variability and complexity of protists.
