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
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
Computer game enabling users to contribute to scientific research about protein folding.
Computer game that allows users to help scientists understand life at the cellular level. Play by designing RNAs, tiny molecules at the hear of every cell. If you win the weekly competition, your RNA is synthesized and scored by how well it folds.

Nature Cell Biology, Published online: 08 September 2021; doi:10.1038/s41556-021-00732-8Zhu et al. report that, in response to growth signals, ERK undergoes TRIM15-mediated lysine-63-linked ubiquitination, which facilitates ERK interaction with MEK and therefore enhances ERK activity.

- Guiding microbes along their pathon September 24, 2021 at 3:35 pm
The interdisciplinary field of active matter physics investigates the principles behind the behavior and self-organization of living organisms. The goal is to reveal general principles that allow to describe and predict the performance of living matter and thereby support the development of novel technologies. Recently, the groups of Oliver Bäumchen and Marco Mazza from the MPIDS, the University of Bayreuth and the University of Loughborough in the UK published their results on the model […]
- When organoids meet coronaviruseson September 24, 2021 at 1:40 pm
Researchers from the group of Hans Clevers in collaboration with the group of Bart Haagmans (Erasmus MC) established an organoid biobank to search for the genes that are essential for the spreading of a SARS-CoV2 infection. Their study was published in Nature Communications on 17 September and highlights the usefulness of organoids for basic research into coronaviruses, as well as highlighting potential drug targets.

In most animals and plants, the life cycle of an individual begins with fertilization, when egg and sperm fuse to combine their genetic material. Together, they form the zygote, the first cell of an embryo that will eventually develop into a complex organism.
- When a chromosome is lost: How do human cells...on September 24, 2021 at 12:54 pm
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were unknown. This is where researchers at the Technical University of Kaiserslautern (TUK) came in. In collaboration with the European Molecular Biology Laboratory (EMBL) in Heidelberg and the Koblenz University of Applied Sciences to investigate the […]
- Dual action: RNA binding protein also binds DNA...on September 23, 2021 at 8:01 pm
Cancer is a devastating disease and is the second leading cause of death in the U.S. One of the hallmarks of cancer is genomic instability, or the tendency to accumulate mutations and damage to the DNA that leads to genome alterations during cell division. DNA mutations can arise from exposure to ultraviolet or X-ray radiation or from certain chemicals known as carcinogens; however, our cells have developed mechanisms to monitor and repair damaged DNA.
