- The smallest piece of ice reveals its true nature
06-21-2007 · EurekAlert!
Collaborative research between scientists in the UK and Germany (published in this week's Nature Materials) has led to a breakthrough in the understanding of the formation of ice. Dr Angelos Michaelides of the London Centre for Nanotechnology (formerly of the Fritz-Haber Institut der Max-Planck Gesellschaft in Berlin) and Professor Karina Morgenstern of the Leibniz University Hannover have combined experimental observations with theoretical modelling to reveal with unprecedented resolution the structures of the smallest pieces of ice that form on hydrophobic metal surfaces.

- Dental crowns reveal the diet of a species:
12-14-2006 · EurekAlert!
According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki's Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal's teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature.

- Time-lapse recordings reveal why IVF embryos are more likely to develop into twins
07-02-2007 · EurekAlert!
Evidence from time-lapse recordings of the formation of early embryos in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. The research presented at annual meeting of the European Society of Human Reproduction and Embryology, Monday, July 2, has shown that the culture in which the IVF embryos are formed is possibly responsible for the embryos dividing into twins.

- Undergraduate research shows leaderless honeybee organizing
06-11-2007 · EurekAlert!
A new finding by an undergraduate scientist and a senior bee researcher gives new insight on the organization of honeybee colonies, which exhibit behavior rivaling human cultures in social complexity. The study reveals that major colony management activities are directed anonymously by hive workers using a nonspecific signal that modulates worker and queen behavior, and may have implications important for understanding other complex phenomena, from brain activity to terrorist networks.
