1. 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.

3. Embryo fossils reveal animal complexity 10 million years before Cambrian Explosion
   10-12-2006 · EurekAlert!
   Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science.

4. DNA analysis reveals rapid population shift among Pleistocene cave bears
   02-19-2007 · EurekAlert!
   Studying DNA obtained from teeth of ancient cave bears, researchers have been able to identify a shift in a particular population of the bears inhabiting a European valley in the late Pleistocene era. The findings illustrate the ability of DNA sequence analysis to reveal aspects of animal population dynamics in the distant past and potentially illuminate the influence of human migrations in animal population changes.

5. Scientists reveal structure of gateways to gene control
   03-28-2007 · EurekAlert!
   The first complete high-resolution map of structures that control how genes are packaged and regulated throughout an entire genome has been compiled by Penn State scientists. The research suggests how certain nucleosomes control whether a gene's function can be turned on. The study reveals an intimate relationship between the architecture of nucleosomes and the underlying DNA sequences they regulate, including a critical gateway that must be unlocked before a gene can be transcribed.

9. Origins of life
   11-17-2006 · EurekAlert!
   The origin of life lies in unique ocean reefs, and Rosenstiel School scientists have developed an approach to help investigate them better. An article published in Geology this month reveals how Dr. Miriam Andres' stromatolite investigation -- the first of its kind -- has begun to "fingerprint" ancient microbial pathways, increasing the understanding of how these reef-like structures form and offering a new way to explore the origins of these living records.

10. Massive project reveals shortcomings of modern genome analysis
    11-07-2007 · EurekAlert!
    The sequencing and comparison of 12 fruit fly genomes -- the result of a massive collaboration of hundreds of scientists from more than 100 institutions in 16 countries -- has thrust forward researchers' understanding of fruit flies, a popular animal model in science. But even human genome biologists may want to take note: The project also has revealed considerable flaws in the way they identify genes.
