Secret to indestructibility: stealing DNA

Washington (AFP) – The minuscule but nearly indestructible tardigrade gets a huge chunk of its genome from the DNA of foreign organisms, which scientists say may hold the key to its survival. Also known as water bears, or moss piglets due to their morphology, these micro animals live all across the world. They are usually 0.020 inches (0.5 millimeters) long and move very slowly and clumsily on their eight legs. These highly adaptable creatures can survive extreme temperatures. Even after being stuck in a freezer at -112 degrees Fahrenheit (-80 Celsius) for 10 years, it can start moving around again about 20 minutes after thawing. By sequencing these creatures’ genome, researchers from the University of North Carolina at Chapel Hill were surprised to find that 17.5 percent – […] Read More
