• Bella moths use poison to attract mates: Scientists are closer to finding out how

    Researchers sequence the bella moth genome, which they used to pinpoint specific genes that may confer immunity to noxious alkaloids.

  • AI tool creates 'synthetic' images of cells for enhanced microscopy analysis
    on April 22, 2024 at 9:08 pm

    Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.

  • World's oases threatened by desertification, even as humans expand them
    on April 22, 2024 at 9:08 pm

    Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the past 25 years as water availability patterns changed and desertification encroaches on these wet refuges.

  • Eye-opener: Pupils enlarge when people focus on tasks
    on April 22, 2024 at 9:08 pm

    Normally, a person's pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person's pupils also dilate when they are concentrating on tasks. In particular, they found that the more a person's eyes dilated during the task, the better they did on tests measuring their working memory.

  • Liquid droplets shape how cells respond to change
    on April 22, 2024 at 7:21 pm

    New research has shown that cells regulate cAMP/PKA signaling by forming liquid droplets that segregate excess PKA catalytic subunits where they can do no harm. Some cancers may block the formation of liquid droplets, leading to hyperactive signaling and tumor formation.
