Overview. Cell and molecular biology research cuts across all science disciplines in Space Biology, from understanding how single-celled organisms, such as protozoa, bacteria, and fungi respond to the conditions of spaceflight, to how all of the various cells in a complex tissue or organ work together to help an organism as a whole acclimate to ...
Apr 23, 2024 · At its 20 centers and facilities across the country – and the only National Laboratory in space – NASA studies Earth, including its climate, our Sun, and our solar system and beyond. We conduct research, testing, and development to advance aeronautics, including electric propulsion and supersonic flight. We develop and fund space ...

Apr 5, 2024 · Studying Cells in Space. Some aspects of life function differently in space, and biologists can learn a lot about how it impacts human health by studying cells grown in the microgravity environment, or weightlessness, of the International Space Station.
Experiments. Cell and Molecular Space Biology Researchers conduct experiments that help develop an understanding of the ways cells (or parts of cells) function and respond to spaceflight. Our studies examine DNA function and structure, cellular and molecular changes, phenotypic changes to organisms, as well as the ability of eukaryotic cells to ...
Space Biology, therefore, funds and conducts research that identifies and characterizes these molecular changes. This includes studies designed to determine how spaceflight alters gene expression at the levels of RNA, protein, and metabolite production in different cell types and tissues, and how these changes impact the organism’s overall ...
A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made.
Apr 19, 2024 · Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.
