  • Plants sacrifice 'daughters' to survive chilly weather
    on June 23, 2017 at 12:50 pm

    Plants adopt different strategies to survive the changing temperatures of their natural environments. This is most evident in temperate regions where forest trees shed their leaves to conserve energy during the cold season. In a new study, a team of plant biologists found that some plants may selectively kill part of their roots to survive under cold weather conditions. […]

  • Protein mingling under blue light
    on June 23, 2017 at 12:50 pm

    One of the current challenges in biology is to understand rapidly-changing phenomena. Interestingly, only a small fraction of them is due to proteins acting in isolation, the majority of biological events are regulated by proteins acting together in clusters. Researchers have developed a new tool, called "CRY2clust", to trigger protein cluster formation in response to blue light. This new technique has a much faster response rate and higher sensitivity to light than existent methods. […]

  • How pheromones trigger female sexual behavior
    on June 22, 2017 at 6:31 pm

    A new study showed how a male pheromone in mice enhances sexual behaviors in females -- and how it may enhance a different behavior, aggression, in males -- by identifying distinct neural circuits and neurons that generate a particular behavioral response to specific chemical signals. The findings point to a model for further investigating how sex-specific innate behaviors in living things are controlled. […]

  • How eggs got their shapes
    on June 22, 2017 at 6:30 pm

    The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery. Now, an international team of scientists took a quantitative approach to that question and found that adaptations for flight may have been critical drivers of egg-shape variation in birds. […]

  • UV-sensing protein in brain of marine annelid zooplankton
    on June 22, 2017 at 4:20 pm

    Larvae of a marine ragworm Platynereis dumerilii have been studied as a zooplankton model, and possess photoreceptor cells in the brain to regulate circadian swimming behavior. This study revealed that a photoreceptive protein in the brain photoreceptor cells is UV (ultra-violet) sensitive. Since avoidance of UV irradiation is a major cause of a large-scale daily movement of zooplankton, the UV sensor in the brain would be important for physiology and ecology of the zooplankton model. […]

  • Cells in fish's spinal discs repair themselves
    on June 22, 2017 at 4:20 pm

    A unique repair mechanism has been discovered in the developing backbone of zebrafish that could give insight into why spinal discs of longer-lived organisms like humans degenerate with age. The repair mechanism protects fluid-filled cells of the notochord, the precursor of the spine, from mechanical stress. Notochord cells eventually form the gelatinous center of intervertebral discs, the structures that often degenerate with age to cause back and neck pain. […]
