New Study Suggests Many Unknown Microbes in Soil
Metagenomic analysis of microbial biodiversity in soil samples suggest that non-bacterial species greatly outnumber bacterial species. This means the majority of microorganisms on the Earth remain undiscovered, according to new research. How Well Do Dogs See At Night?
Dogs see a lot better than humans do at night. Dogs have many adaptations for low-light vision. A larger pupil lets in more light. The center of the retina has more of the light-sensitive cells (rods), which work better in dim light than the color-detecting cones. Differences In Gene Usage Dramatically Change Bacteria's 'Lifestyles'
When and where a bacterium uses its DNA can be as important as what's in the DNA, according to researchers at Washington University School of Medicine in St. Louis. Scientists found significant differences in two bacterial organisms' use of a gene linked to processes that govern a form of antibiotic resistance. The distinction alters the bacteria's "lifestyles,"or their ability to survive in different environments. Elephants Imitate Sounds As A Form Of Social Communication
Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some birds, and bats. Holier Than Thou? Employees Who Believe They Are 'Ethical'Or 'Moral'Mi
A moral identity motivates behavior but accurate, ethical judgments are needed to set that behavior in the right direction, according to researchers who study business ethics. New Tech for Hyper Color TV

Carnegie Mellon University chemical engineers have a devised a new process that can improve the efficiency of ethanol production, a major component in making biofuels a significant part of the U.S. energy supply. Researchers Find Two Biomarkers With Potential To Predict Breast Cance
Expression of two different proteins taken from primary tumor biopsies is highly associated with spread of breast cancer to nearby lymph nodes, according to researchers who say this protein profile could help identify at an early stage those patients whose disease is likely to metastasize. Baby 'Planemos' Can Be Born As Twins
Astronomers are challenging an existing theoretical model and thrilling the astronomy community with their discovery of a seven-Jupiter-mass companion next to a planemo, or planetary mass object, only twice as heavy. Both objects have masses similar to those of extra-solar giant planets, usually found in orbit around a star. Unexpectedly, these bodies appear to circle each other.
