  • Team reports on the occurrence of antibiotic resistance genes in the western Qinghai Lake basin
    on March 21, 2024 at 9:25 pm

    Antibiotic resistance genes (ARGs) have been widely detected in water, sediment, gut and even the phycosphere of algae. In strong anthropogenic activity areas, antibiotic resistance caused by ARGs can pose a significant threat to human health. Despite the numerous published studies on the occurrence and distribution of ARGs in these areas, there is a dearth of literature on the presence and dispersal of ARGs in remote and pristine environments with limited antibiotic usage.

  • Improving root senescence recognition with a new semantic segmentation model
    on March 21, 2024 at 9:22 pm

    Roots play a vital role in plant health, adapting to environmental changes and indicating crop growth. However, studying root senescence is challenging due to difficulties in obtaining clear in situ root images. Traditional methods are limited, and while in situ cultivation and advanced imaging techniques offer some solutions, they face issues such as high costs and low image quality. Recent advances in deep learning, particularly semantic segmentation models like SegNet and UNet, have improved root identification but still require further optimization.

    on March 21, 2024 at 8:36 pm

    Plants have an extremely high capacity to adapt to their environment. When the seeds of pea sprouts left over from cooking are soaked in water, the sprouts and leaves grow back. Associate Professor Kondo Yuki of Kobe University's Graduate School of Science has focused his research on vascular bundles, which are essential for environmental adaptation.

  • Seven billion newly hatched chicks are killed every year—but a ban is not the solution, says study
    on March 21, 2024 at 8:36 pm

    With Easter just around the corner, we are surrounded by a ubiquity of eggs and adorable yellow chicks that symbolize life and resurrection. In stark contrast is the fact that around seven billion male layer chicks, are shredded or gassed alive by the egg industry every year, just hours after they hatch. Male chicks of course cannot lay eggs, and they are furthermore not worth fattening up like broilers, due to decades of specialized breeding toward either egg laying or meat production—but not both.

  • In a first, team identifies mysterious exporter for brassinosteroid plant hormone
    on March 21, 2024 at 7:54 pm

    When you are reading this article, there are multiple hormones working diligently inside your body to stabilize your health status. Just as in human beings, it is impossible for plants to grow and reproduce without being regulated by phytohormones. One of the phytohormones is the brassinosteroid (BR) hormone, also named as the sixth phytohormone.

  • As we age, our cells are less likely to express longer genes
    on March 21, 2024 at 7:53 pm

    Aging may be less about specific 'aging genes' and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers. A decline in the expression of long genes with age has been observed in a wide range of animals, from worms to humans, in various human cell and tissue types, and also in individuals with neurodegenerative disease. Mouse experiments show that the phenomenon can be mitigated via known anti-aging factors, including dietary restriction.
