New imaging method clarifies nutrient cycle
... atmosphere, both carbon and nitrogen. For decades biologists wondered how the organism could fix both elements, since carbon fixation associated with photosynthesis produces oxygen, while nitrogen fixing needs an oxygen-free environment. Previous studies have shown that some photosynthetic cells can differen...Bioinformatics-related methods are featured in Cold Spring Harbor Protocols

University of Oregon biologists studying a common ocean-dwelling worm have uncovered potentially fundamental insights into the evolutionary origin of genetic mechanisms, which when compromised in humans play a role in many forms of cancer. Their research, appearing in the July i...Loss of cell's 'antenna' linked to cancer's development
...iscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.
