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.

Scientists have discovered that a certain clone of Borrelia burgdorferi, the spirochete that causes Lyme disease, appears to be the most common strain causing Lyme disease in North America and Europe, and may account for the increase in cases for the past 20 years.
Huge Genome-scale Phylogenetic Study Of Birds Rewrites Evolutionary Tree-of-life

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 Fossils Of Extremely Primitive 4-Legged Creatures Close The Gap Between Fish And Land Animals

New exquisitely preserved fossils from Latvia cast light on a key event in our own evolutionary history, when our ancestors left the water and ventured onto land. Scientists have reconstructed parts of the animal and explain the transformation in the new issue of Nature.
Nanotubes Could Help Study Retrovirus Transmission Between Human Cells

Naturally occurring nanotubes may serve as tunnels that protect retroviruses and bacteria as they infect healthy cells. The unexpected shielding may explain why vaccines fare poorly against some invaders. Researchers now have formed similar nanotubes that could be used to duplicate the phenomenon.

During the past 15 years, the global cocoa industry has confronted a trio of devastating fungal diseases that cost growers an estimated $700 million in losses annually. Now scientists at the Agricultural Research Service (ARS) Subtropical Horticultural Research Station (SHRS) in Miami, Fla., are developing productive cacao (Theobroma cacao) trees resistant to these diseases: witches' broom, frosty pod and black pod.

Quotes:
I'm afraid I'm being an awful nuisance.
You can be confident and secure and know that you do a good job at what you do. But you don't know to be arrogant about it.
If you don't learn to laugh at trouble, you won't have anything to laugh at when you're old.
