Consciousness is the most intimate aspect of human existence—and the least understood. It is the silent observer behind every thought, emotion, and perception, yet it lacks precise definition. Despite centuries of philosophical studies and decades of scientific research, consciousness remains an enigma at the intersection of biology, physics, and philosophy. What Is Consciousness? At its simplest, consciousness can be described as subjective experience, the feeling of “what i

The brain is primarily isolated from the rest of the body, it is protected from the body’s immune system by blood brain barrier. The central nervous system (CNS) has its own specialised immune cells called microglia. These highly dynamic cells continuously survey the brain’s environment, immediately responding to injuries, infection and changes in neural activity. Microglia are also play important role in shaping brain development, maintaining neural circuits and influence

Induced pluripotent stem cells (iPSCs) represent one of the most transformative advances in modern biology. It was first reported by Shinya Yamanaka and colleagues in 2006. These iPSCs are adult (somatic) cells that have been genetically reprogrammed back into a pluripotent state-meaning they regain the ability to self-renew indefinitely and differentiate into virtually any cell type of the body. This discovery fundamentally changed the landscape of stem cell research. By byp

When. we think about the brain, neurons usually steal the spotlight. The fire action potential, transmit information and form the circuites underlying thought and behavior. Yet neurons make only about half of the brain's cells. The rest are glial cells and among them, astrocytes are arguably the most versatile and influential. Once dismissed as passive "support cells," astrocytes are now recognized as active regulators of brain development, signalling, metabolism, and disease
