cell : a small usually microscopic mass of protoplasm bounded externally by a semipermeable membrane, usually including one or more nuclei and various other organelles with their products, capable alone or interacting with other cells of performing all the fundamental functions of life, and forming the smallest structural unit of living matter capable of functioning independently — Webster

OneLook, Free Dictionary, Wiktionary


Cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are often called the “building blocks of life”. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Organisms can be classified as unicellular (consisting of a single cell; including bacteria) or multicellular (including plants and animals). While the number of cells in plants and animals varies from species to species, humans contain more than 10 trillion cells. Most plant and animal cells are visible only under a microscope, with dimensions between 1 and 100 micrometres. — Wikipedia

Cell biology (also called cytology) is a branch of biology that studies the structure and function of the cell, which is the basic unit of life. Cell biology is concerned with the physiological properties, metabolic processes, signaling pathways, life cycle, chemical composition and interactions of the cell with their environment. This is done both on a microscopic and molecular level as it encompasses prokaryotic cells and eukaryotic cells. Knowing the components of cells and how cells work is fundamental to all biological sciences; it is also essential for research in bio-medical fields such as cancer, and other diseases. Research in cell biology is closely related to genetics, biochemistry, molecular biology, immunology, and developmental biology. — Wikipedia

    on September 30, 2022 at 1:38 pm

    The study of blastoids, a research model of an early embryo derived from stem cells rather than from a father's sperm or a mother's egg, offers great hope for researchers investigating why pregnancies are lost at an early stage, what causes birth defects, and other topics related to early human development. Their use potentially avoids the challenges of scarcity and potential ethical problems of using actual embryos for the same sort of research.

    The researchers from the Institute of Microbiology of the Chinese Academy of Sciences have developed a miniaturized bionic ocean-battery, a bio-solar cell that converts light into electricity, by mimicking the basic ecological structure of marine microbial ecosystems. This study was published in Nature Communications.

    The neurohormone oxytocin is well-known for promoting social bonds and generating pleasurable feelings, for example from art, exercise, or sex. But the hormone has many other functions, such as the regulation of lactation and uterine contractions in females, and the regulation of ejaculation, sperm transport, and testosterone production in males.

  • 'Mystery gene' matures the skeleton of the cell
    on September 29, 2022 at 6:00 pm

    "I'm a professional pin-in-a-haystack seeker," geneticist Thijn Brummelkamp responds when asked why he excels at tracking down proteins and genes that other people did not find, despite the fact that some have managed to remain elusive for as long as 40 years.

  • New bacterial species discovered in the intestine
    on September 29, 2022 at 5:24 pm

    Whether plant, animal or human, living organisms are colonized by a multitude of bacteria. Research findings in recent years show that bacteria not only co-exist with their host, but form mutual interactions in the form of a symbiosis that can benefit both the bacterium and the host.

    Nature Cell Biology, Published online: 27 September 2022; doi:10.1038/s41556-022-01004-9Cellular senescence induced by DNA replication and telomere attrition contributes to organ dysfunction, inflammation and impaired immunity. A study reveals that antigen-presenting cells provide telomeric DNA to CD4+ T cells in synaptic contact, which enables the suspension of senescence, T cell expansion and long-lived immunity.
