Scientists have recently identified a fascinating new form of water ice known as Plastic Ice-7, a high-pressure phase with unique properties. Unlike regular ice, this form remains structurally stable under extreme conditions but exhibits an unusual “plastic” behavior, where water molecules move in a disordered yet solid state. Plastic Ice-VII (Ice-7p) is a newly discovered […]

“Dark oxygen” refers to the production of oxygen in deep-sea environments without the involvement of sunlight or photosynthesis. Traditionally, oxygen generation has been attributed to photosynthetic organisms like plants and algae that require sunlight. However, recent discoveries have unveiled alternative mechanisms operating in the ocean’s depths. Recent Discoveries: Abyssal Seafloor Observations: In mid-2024, scientists detected […]

Electrostatics is the branch of physics that deals with the study of electric charges at rest. It focuses on the forces, fields, and potentials associated with static electric charges. Electric Charge Electric charge is a fundamental property of matter that governs the interaction between particles through electromagnetic forces. It is responsible for electric and magnetic […]
