How do tardigrades survive without water?

Post by Nahid#13 »

The discovery focuses on a newly discovered mechanism that kicks in when dehydration sets in, protecting cells from dying due to mechanical stress. Also known as water bears, microscopic tardigrades are renowned for their resilience to all kinds of extreme conditions, and the more we learn about them, the more impressive their survival skills seem. The research details how tardigrades use DNA clouds and fluorescent shields to protect against various types of radiation. They are also known to go into limbo to survive the boiling and freezing temperatures and crushing pressures of the ocean floor. Studies even suggest that they survived.

The team studied cytoplasmic high-temperature soluble (CAHS) proteins, which recent studies have shown are activated in tardigrades once dehydration begins. Exploring their role further, the team found that in dehydrated tardigrade cells, the proteins combine to form a gel-like network of protective fibers that help the cells maintain their shape when the water content drops.

When the tardigrade cells have been rehydrated, the process reverses - the filaments slowly retract to avoid mechanical stress in the cell. CAHS proteins form gel-like fibers in response to dehydration While water is essential to all life as we know it, some tardigrades can live without it potentially for decades , said study author Takayasu Kaneda. The trick is how their cells deal with this stress during the dehydration process. It is believed that when the water leaves the cell, some type of protein must help the cell maintain its physical strength to avoid collapsing. After testing several different types, we found that CAHS proteins, unique to tardigrades, are responsible for protecting their cells from dehydration.
