Emerging Intracellular Electrical Phenomena: Implications for Paradigm Shifts in Biological Chemistry Research

Summary of the article  The human body depends on electrical charges for many biological processes, including brain activity and nerve impulses. Previously, it was believed that cellular membranes were necessary to create an electrical charge imbalance. However, recent research from Stanford University has shown that a similar electrical imbalance can exist between microdroplets of water and air. Now, researchers from Duke University have discovered that these types of electric fields also exist within and around biological condensates, a type of cellular structure. These structures form compartments inside the cell without needing the physical boundary of a membrane. The researchers discovered that when environmental conditions are right, a previously unknown phenomenon occurs in these biological condensates, which creates a redox reaction that produces tiny amounts of hydrogen peroxide. This discovery could change the way researchers think about biological chemistry and provide a clu

Air pollution and its health consequences

Follow @OmEnigma  Air pollution is the changing of the natural features of the atmosphere by any chemical, physical, or biological factor in either the indoor or outdoor environment. These chemical, physical or the biological ingredients responsible for the change in natural quality of air are air pollutants. Common causes of air pollutants include smoke from motor vehicles, industrial operations, household combustion appliances, and forest fires. Particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide are pollutants of great public health concern. Indoor and outdoor air pollution are significant contributors to morbidity and mortality because they cause respiratory and other illnesses. Multiple and situation-specific sources contribute to air pollution. Residential energy use for heating and cooking, transportation, power production, agriculture/waste incineration, and industry are the main causes of outdoor pollution. Key sources of ambient air pollution ca
