- Sugars Killing Coral Reefs (11/09/06) - Bacterial growth, stimulated by the presence of simple sugars in untreated sewage and agricultural runoff, can now be added to the list of things contributing to the demise of coral reefs.
- Oceans Full of Microbes (09/01/06) - Researchers working on the International Census of Marine Microbes find microbial life in the ocean is far more diverse than ever imaged.
- Human Gut Microbes Sequenced (08/08/06) - If you're sitting in a room by yourself, don't think you're alone. You have the company of trillions of microbes living in your gut and other parts your body. And now, the genomes of the ones living in your gut have been sequenced via a metagenomics approach.
- Sputum Samples May Predict Lung Cancer (05/26/06) - A non-invasive test currently under investigation may be able to predict who will get lung cancer as much as 18 months before people show any other signs of the disease. And to do the test, all people have to do is provide a sputum sample.
- The Heart that Glows (4/27/06) - Genetically altered mice have hearts that glow green -- a feature that lets researchers study how cells communicate, and how the heart grows and develops.
- Does Soy Really Work? (3/17/06) - Soy helps lower cholesterol levels, but only when it is part of a whole heart-healthy diet plan. A study from the American Heart Association sheds light on the confusion.
- Ancient Swarm of Locusts Made Trans-Atlantic Trip (1/27/06) - Genetic detective work has revealed that various grasshopper species in North America are descended from the desert locust from Africa that migrated to the Americas between three to five million years ago. The research solves a number of mysteries about grasshoppers and locusts on both continents, according to Nathan Lovejoy, PhD, professor of life sciences at the University of Toronto.
- More Flu Viruses Around (11/29/05) - Genetic studies of the human influenza virus are changing the understanding of how fast and how frequently viruses mutate. New studies show that flu viruses swap genetic information far more frequently than was thought, and that there are more versions of flu than researchers suspected.
