    Article: 25 min

    A study by biologists and neuroscientists suggests that even simple networks of biomolecules, like gene regulatory networks (GRNs), can display agency and self-like behavior. This revelation could lead to novel ways of treating health conditions with fewer side effects and provide insights into the origins of life and consciousness.

    This research could lead to more targeted and less invasive medical treatments, potentially reducing the side effects of medications and improving patient outcomes.
    • Biologists have been investigating where cognition shows up outside the brain, finding surprising abilities like learning and memory in organisms as simple as slime molds and single-celled organisms.
    • GRNs can learn features of their environment through associative learning, similar to Pavlov's dogs. This could allow for reduced side effects from medicines or triggering powerful medicine effects with less harmful substances.
    • The study suggests that agency itself might drive evolution towards more complex forms of life, as parts come together to form new levels of control and cooperation.

    Discussion (13):

    The comment thread discusses the science fiction novel 'Blood Music' by Greg Bear, with opinions on its unique progression and high regard. There is also a debate about an article regarding Pavlov's dog experiment and criticism of modern journalism.
