The largest ever study of bird genetics redraws the avian evolutionary tree, challenges current classifications, alters our understanding of avian evolution, and provides a resource for future studies. Early Bird, centered at the Field Museum, examined DNA from all major living bird groups. Scientists built and analyzed a dataset of more than 32 kilobases of nuclear DNA sequences from 19 locations on the DNA of each of 169 species -- equivalent to a small genome project.

New research could help with the large-scale cultivation and manufacturing of oil-rich algae in oceans for biofuel. Algae are a diverse and simple group of organisms that live in or near water. Certain algal species are high in oil content that could be converted into such fuels as biodiesel, according researchers. Algae also have several environmentally-friendly advantages over corn or other plants used for biofuels, including not needing soil or fresh water to grow.

When fatigued individuals perceive a task as being achievable and worth doing, they increase their effort to make up for their diminished capability due to fatigue. As a result, blood pressure tends to rise and remain elevated until the task is completed or individuals stop trying because they think success is impossible or too difficult to be justified.
