Technology 101: The Illusive Blue LED – From Myth to Reality

Blue LED light emitting diodes Electrical Electricity Computing

The blue , a pivotal innovation in lighting , was developed in the early 1990s by Shuji Nakamura, along with Isamu Akasaki and Hiroshi Amano. This invention was significant enough to earn them the Nobel Prize in Physics in 2014. Blue LEDs are essential because they have a higher gap, allowing for the production of blue , which, when combined with red and green LEDs, can create white light. This advancement has led to energy-efficient lighting solutions that are revolutionizing industries and consumer products worldwide. Photo by panumas nikhomkhai

Health 101: Strategies for Boosting Weak Immune System Naturally

Immune System Health Virus

Lymphocytes are a vital component of the , classified as a type of white blood cell. They are primarily responsible for the body’s immune response to foreign invaders such as viruses and bacteria. There are three main types of lymphocytes: B cells, T cells, and natural killer (NK) cells, each with a unique role in detecting and responding to pathogens. B cells produce antibodies, T cells can directly kill infected cells or help other immune cells, and NK cells are involved in the destruction of cancer cells and virus-infected cells.
