Water is the fundamental molecule for life on Earth. Thus, the search for hibernating life-forms in waterless environments is an important research topic for astrobiology. To date, however, the organizational patterns containing microbial life in extremely dry places, such as the deserts of Earth, the Dry Valleys of Antarctica, or Mars analog regolith, have been poorly characterized. Here, we r...

Mechanical robustness of the cell under different modes of stress and deformation is essential to its survival and function. Under tension, mechanical rigidity is provided by the cytoskeletal network; with increasing stress, this network stiffens, providing increased resistance to deformation. However, a cell must also resist compression, which will inevitably occur whenever cell volume is decr...

PAPER Alan Tunnacliff e et al. Intrinsically disordered proteins as molecular shields. The broad family of LEA proteins are intrinsically disordered proteins (IDPs) with several potential roles in desiccation tolerance, or anhydrobiosis, one of which is to limit desiccation-induced aggregation of cellular proteins. We show here that this activity, termed molecular shield function, is distinct f...

The glass transition in sugars is important for several reasons. First, sugar glasses are very effective materials for cryopreservation and anhydrobiosis. Second, biochemists commonly use sugars to suspend biomaterials in a glassy matrix for spectroscopic studies. Third, the glass transition in sugars is important in the food industry. The texture of candies or cookies mainly depends on the gla...

The broad family of LEA proteins are intrinsically disordered proteins (IDPs) with several potential roles in desiccation tolerance, or anhydrobiosis, one of which is to limit desiccation-induced aggregation of cellular proteins. We show here that this activity, termed molecular shield function, is distinct from that of a classical molecular chaperone, such as HSP70 - while HSP70 reduces aggreg...

Water is essential for all living systems, yet a number of meiofaunal organisms are able to withstand almost complete desiccation through state suspended animation called anhydrobiosis. Tardigrades especially unique in that many them can enter anhydrobiosis very short period time compared anhydrobiotic arthropods such as sleeping chronomid and artemia accumulate large amount disaccharide trehal...
