#TIL In the 1950s, #scientists cooled hamsters/rats to near-freezing and used #microwave diathermy to revive them. Not quite “frozen mice in a microwave,” but still a wonderfully weird chapter in cryobiology history. 🐹❄️📡

A research echoed recently by a team from #germany #fau that succeeded in preserving #brain tissue through extreme deep #freezing
A VARIETY of cells and tissues of mammals survive for long periods at the temperature of ‘dry ice’ − 79° C., when frozen in media containing glycerol1. At the other extreme, Andjus's work on the whole animal shows that, by special methods of cooling and rewarming, rats can be revived from deep body temperatures of about + 0.5° C.2. We are now attempting to close the gap between these two lines of work (a) by increasing the size and complexity of the isolated tissue cooled to − 79° C., as, for example, by freezing a whole isolated organ3, and (b) by reducing the whole animal to a body temperature below zero. This communication deals with experiments on the second of these developments.

“Frozen Waves”
Photographer Jan Erik Waider is a master of capturing incredible landscape imagery. In these videos, he uses a drone to film waves in the Baltic Sea gently undulating polygonal slabs of ice on the ocean surface. The interplay of light, color, and motion looks almost surreal, but nature is better than we credit at making imagery too good to look away from. (Video and image credit: J.

A Fungus That Freezes Water
Although water can freeze below 0 degrees Celsius, it requires a little help–in the form of a nucleation site–to do so. Often temperatures must dip well below 0 degrees Celsius for droplets to become ice. But a new study shows that at least one fungus forms proteins that help the process along.
The proteins come from the Mortierellaceae fungal family, by way of a bacterial species some hundreds of thousands of years ago or more. In experiments, adding the fungal protein helped water freeze 10 or more degrees Celsius sooner than it otherwise would.
The authors note that there are many possible applications for this freezing additive; it could help preserve food or cells without requiring lower freezing temperatures that could damage delicate tissues. It could also serve as a cloud seeding chemical in place of toxic silver iodide particles. (Image and research credit: R. Eufemio et al.; via Gizmodo; see also V. Tech)
