  What If Neurons Could Regenerate? Imagine a world where your brain could heal and renew itself like your skin or liver. How would that change your life? Would you still be the same person, or would you evolve into someone entirely different? Let’s dive into this mind-bending idea together. The top image shows fluorescently labeled cells in the spinal cord of a zebrafish recovering one week after an injury, and the bottom image shows recovery four weeks after an injury. Researchers at Washington University School of Medicine in St. Louis describe the dramatic changes within nerve cells that make regeneration possible. Such findings could inspire the development of new therapies for spinal cord injuries in people.

Learning could become faster and more efficient, making knowledge ret...

TOKYO: Japan  has given the green light to a controversial research process involving implanting animals with human stem cells that could eventually help grow human organs for transplant inside animal hosts. The decision by the education and science ministry on Friday to revise its guidelines means Japanese researchers can now apply for permits to carry out studies employing the technique, a ministry official said. The process involves implanting embryonic animals, likely first pigs, with human “induced pluripotent stem” (iPS) cells, which can transform into the building blocks of any part of the body. The idea is for the iPS cells to grow into transplantable human organs inside the animal embryos. Japan had previously required researche rs to terminate animal embryos implanted with human cells after 14 days “due to ethical concerns over the vague line between human beings and animals,” the official said. The old regulations also prevented researchers from placing th...

Mind Meets Body: Unlocking the Secrets of Brain–Body Communication By Arya Bandyopadhyay | Exploring the Mind–Body Code Your body and brain are in constant dialogue. Far from being a one-way system, this relationship is dynamic and bidirectional—your brain listens, learns, and rewires itself based on feedback from the body. Understanding this intricate network opens doors to rethinking health, emotion, and disease. 1. The Brain Listens: Vagus Nerve & Organ Signals Illustration of the vagus nerve, highlighting its pathway and connection to vital organs, influencing the autonomic nervous system. Image Credits: advancedbrain.com Signals from organs like the gut and lungs reach the brain via the  vagus nerve . These inputs affect everything from immunity to emotion. Gut microbes, for example, help produce neurotransmitters that affect your mood. “Your second brain—the gut—has more power than you think.” 2.
