If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such antifreeze, living matter would suffer from frost damage and even death. Production of such antifreeze proteins is one of the major evolutionary routes taken by a variety of organisms, including fish,...

Alpha Galileo Foundation Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides Canadensis manages to withstand temperatures down to -30 degrees Celsius is reported by an international team of researchers led by Prof. Dr. Martina Havenith from the Department of Physical Chemistry II at the Ruhr-Universität in the journal PNAS. Together with American colleagues, the RUB-researchers...

Scientists have made an important step forward in their understanding of cryoprotectants "“ compounds that act as natural 'antifreeze' to protect drugs, food and tissues stored at sub-zero temperatures. Researchers from the Universities of Leeds and Illinois, and Columbia University in New York, studied a particular type of cryoprotectants known as osmolytes. They found that small osmolyte molecules are better at protecting proteins than larger ones. The findings, published in...

Researchers report that they are the first to show in molecular detail how one gene evolved two competing functions that eventually split up "“ via gene duplication "“ to pursue their separate destinies. The study, in the Proceedings of the National Academy of Sciences, validates a decades-old hypothesis about a key mechanism of evolution. The study also confirms the ancestry of a family of "antifreeze proteins" that helps the Antarctic eelpout survive in the frigid waters of the...

RUB chemists unmask natural antifreezeTogether with cooperation partners from the U.S., the researchers surrounding Prof. Dr. Martina Havenith (Physical Chemistry II of the RUB) describe their discovery in a so-termed Rapid Communication in the prestigious American chemistry journal, the Journal of the American Chemical Society (JACS). The journal's independent reviewers evaluated the work as one of the top 5% of all submissions.Better than household antifreezeTemperatures of minus 1.8 °...

KINGSTON, ON "“ The same antifreeze proteins that keep organisms from freezing in cold environments can also prevent ice from melting at warmer temperatures, according to a new Queen's University study. The study presents the first direct measurements of the superheating of ice crystals in antifreeze protein solutions. Superheated ice crystals can be stabilized above the melting point for hours, at a maximum temperature of about +0.5 degree Celsius. "You can hold the ice crystal at...

Scientists publish first direct measurements of 'superheating' phenomenon The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio University and Queen's University study published today in the Early Edition of the journal Proceedings of the National Academy of Sciences. Antifreeze proteins are found in insects, fish, bacteria and other organisms that need to survive in cold...

Scientists have identified a novel antifreeze molecule in a freeze-tolerant Alaska beetle able to survive temperatures below minus 100 degrees Fahrenheit. Unlike all previously described biological antifreezes that contain protein, this new molecule, called xylomannan, has little or no protein. It is composed of a sugar and a fatty acid and may exist in new places within the cells of organisms. "The most exciting part of this discovery is that this molecule is a whole new kind of antifreeze...

Water expands when it freezes. Anyone who has ever left a can of soda or bottle of water in the freezer too long has witnessed this first hand. So how do plants and animals survive severe temperatures? Insects exposed to subzero temperatures can adapt to the extreme climate to survive freezing temperatures, but until now, antifreeze molecules had not been isolated from freeze-tolerant animals. The NSF-supported study, published in the November 24 issue of Proceedings of the National Academy...
