And plant pathogens, ... Arpa Hudait conducted molecular simulations of protein interactions with water molecules to see how they affected the temperature of ice nucleation.

Ice Nucleation and Freezing Stress in Plants. The site of ice nucleation, as well as the temperature at which nucleation occurs, is a major determinant of the measure of freezing injury. Ice crystals ...

New research explores how proteins produced by a common fungus trigger ice nucleation at warm temperatures. ... PLANTS & ANIMALS. Long Shot Science Leads to Revised Age for Land-Animal Ancestor.

Overview of the two modes of ice nucleation. (A) Representative pathways through temperature-saturation phase space.In immersion freezing, supercooled water follows the line of water saturation as ...

ICE, ICE BABY Pseudomonas syringae bacteria can freeze water at above-freezing temperatures, so they’re often used to help make artificial snow for ski slopes. Mr. Green/Shutterstock Share this: ...

Ice nucleation in nature cannot occur from mildly supercooled bulk water. When liquid water is supercooled down to 20° below melting, the ice nucleation rate is slower than the rate corresponding to ...

Clouds affect Earth’s weather and climate in many ways. New research suggests that the presence of microplastic particles may affect weather and climate by producing clouds in conditions where ...

Scientists first spotted biological ice nucleation in the 1970s when studying the bacteria Pseudomonas syringae, a plant pathogen that causes multiple diseases in crops.

“Ice nucleation is one of the most common phenomena in the atmosphere,” says Valeria Molinero, a professor of physical and materials chemistry. “In the 1950s and 1960s, there was a surge of interest ...

Instead, ice crystals begin forming at tiny "nuclei" and spread throughout the body of water in a process called nucleation. Lower temperatures promote nucleation events and hence speed up the ...
