Bacteria, plants, insects, or even fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, a German–Israeli research team has confirmed that these proteins also possess an unusual second property: at low temperatures, they can promote rather than inhibit the growth of ice crystals. The study brought together researchers from Bielefeld University, the Hebrew University of Jerusalem, and the Weizmann Institute of Science in Rehovot (Israel). It is being published today (07.03.2019) in the ‘Journal of Physical Chemistry Letters’.[Weiterlesen]
