Cryobiology is the study of the effects of low temperatures on living organisms. This field explores how cells, tissues, and entire organisms respond to freezing and thawing processes. Researchers investigate the mechanisms that allow some organisms to survive extreme cold, such as certain species of frogs and tardigrades, which can endure freezing temperatures without damage. In addition to understanding survival strategies, cryobiology has practical applications in medicine and biotechnology. For example, it plays a crucial role in cryopreservation, a technique used to store cells, tissues, and organs at very low temperatures for future use. This method is essential for preserving sperm, eggs, and embryos in fertility treatments.
