Venting when angry seems sensible. Conventional wisdom suggests expressing anger can help us quell it, like releasing steam from a pressure cooker. But this common metaphor is misleading, according to a new meta-analytic review. Researchers at Ohio State University analyzed 154 studies on anger, finding little evidence that venting helps. In some cases, it could increase anger. "I think it's really important to bust the myth that if you're angry you should blow off steam – get it off your chest," says senior author Brad Bushman, a communication scientist. "Venting anger might sound like a good idea, but there's not a shred of scientific evidence to support catharsis theory."

My Physiology teacher made my class go back in time, to the Paleozoic era, and we had to transform into animals to discover their everyday lives. I was a rat and had to eat earthworms the size of a garden hose. Then we went back to the present and had to rate our experience out of 20. I wrote 🤡/20.

Just finished a hellish week in my life studying for 2 quizzes and 1 exam. I think that one of the worst feelings in the world is studying until you drop, then finding out you got points off on a quiz because of a silly mistake.

Point is: I need to sleep more 😭

🧪The sodium-potassium pump🧬

Greetings, Tumblr community! 🧠💡 Let's engage in a comprehensive exploration of the sodium-potassium pump, dissecting its molecular intricacies and elucidating its critical role in cellular homeostasis.

Introduction:

The sodium-potassium pump, residing within the cellular membrane, is an adenosine triphosphate (ATP)-dependent transmembrane protein pivotal for maintaining ionic balance. Its primary function is to actively transport three sodium ions out of the cell while concurrently importing two potassium ions.

Functional Mechanism:

In terms of mechanistic precision, the sodium-potassium pump operates as an ATPase enzyme, utilizing the energy derived from ATP hydrolysis. This primary active transport process involves sequential conformational changes within the pump's structure.

The process commences with the binding of intracellular sodium ions to high-affinity sites on the pump. Subsequent phosphorylation, facilitated by ATP, induces conformational alterations that render the pump receptive to extracellular potassium ions. This triggers dephosphorylation, allowing potassium ions to be released intracellularly.

This orchestrated ion exchange serves to uphold the electrochemical gradient across the cellular membrane, establishing and preserving the resting membrane potential. In essence, the sodium-potassium pump is the architect of the delicate balance between sodium and potassium concentrations.

Physiological Significance:

The physiological ramifications of this meticulous ion transport extend to neuronal excitability and osmoregulation. By contributing to the establishment of the resting membrane potential, the pump plays a pivotal role in regulating action potentials and facilitating the propagation of nerve impulses.

Additionally, the pump actively participates in cellular volume control through osmoregulation. Its influence on water movement prevents cellular swelling or shrinkage, underscoring its significance in maintaining cellular integrity.

Scientists have discovered a 'secret passageway' in mice that connects the brain to the body's lymphatic system. The network of vessels appears to form an overlooked brain drainage system that plays a crucial role in maintaining the health and function of the central nervous system. If the findings extend to humans, it could fundamentally change how scientists understand the circulation of fluid that bathes the brain and spinal cord.

Touch is the sensory mode which integrates our experiences of the world and of ourselves. Even visual perceptions are fused and integrated into the haptic continuum of the self; my body remembers who I am and how I am located in the world. My body is truly the navel of my world, not in the sense of the viewing point of the central perspective, but as the very locus of reference, memory, imagination and integration. All the senses, including vision, are extensions of the tactile sense; the senses are specialisations of skin tissue, and all sensory experiences are modes of touching, and thus related to tactility. Our contact with the world takes place at the boundary line of the self through specialised parts of our enveloping membrane.
