Out of Africa-Bacteria, as well
When man made his way out of Africa some 60,000 years ago to populate the world, he was not alone: He was accompanied by the bacterium Helicobacter pylori, which causes gastritis in many people today. view more (2007-02-15)
Emphasis on conifer forests places multiple species at risk
The traditional emphasis on dense, fast-growing, conifer-dominated forests in the Pacific Northwest raises questions about the health of dozens of animal species that depend on shrubs, herbs and broad-leaf trees, a new analysis by Oregon State University and the U.S. Geological Survey suggests. view more (2007-08-24)
Geographic isolation drives the evolution of a hot springs microbe
Sulfolobus islandicus, a microbe that can live in boiling acid, is offering up its secrets to researchers hardy enough to capture it from the volcanic hot springs where it thrives. view more (2009-05-28)
Different coat color may not mean different species for lemurs
Researchers have found that lemurs suspected to belong to different species because of their strikingly different coat colors, are not only genetically alike, but belong to the same species. view more (2006-11-16)
ESA's Medspiration project branches out to support biodiversity
Maps of the sea surface temperature around Galapagos Islands and Cocos Island in the Pacific Ocean are being produced daily and are available online in full resolution in near-real time as part of the Medspiration project, an ESA-funded effort to represent the most reliable temperature of the seas on a global basis. view more (2007-03-20)
Longest study finds reef fish need longer break
In the longest running study on how fish populations in coral reef systems recover from heavy exploitation, researchers from the Wildlife Conservation Society (WCS) and others have found that the fish can recover, but they need lots of time - decades in some cases. view more (2007-07-12)
Iowa State professor's research shows Midwest forests losing diversity, complexity
Forests in the nation's Upper Midwest have changed greatly since the time of the early settlers. And more changes may be coming. view more (2007-10-17)
Antibiotics take toll on beneficial microbes in gut
It's common knowledge that a protective navy of bacteria normally floats in our intestinal tracts. Antibiotics at least temporarily disturb the normal balance. view more (2009-06-19)
Genomics throws species definition in question for microbes
Until a decade ago, scientists categorized microorganisms almost exclusively by their physical characteristics: how they looked, what they ate, and the by-products they produced. view more (2007-03-27)
Thousands of Crop Varieties from Four Corners of the World Depart for Arctic Seed Vault
At the end of January, more than 200,000 crop varieties from Asia, Africa, Latin America and the Middle East-drawn from vast seed collections maintained by the Consultative Group on International Agricultural Research (CGIAR)-will be shipped to a remote island near the Arctic Circle, where they will be stored in the Svalbard Global Seed Vault... view more...

Ancient DNA provides clues to the evolution of social behavior
A rare Patagonian rodent known as the colonial tuco-tuco fascinates biologists because it seems to defy all odds. This threatened species has so little genetic diversity that the slightest whiff of climate change or disease should have wiped it off the face of the earth long ago. view more (2006-04-21)
Researchers find demand for cosmetic and surgical procedures in dermatologic surgery rising rapidly
Researchers from Boston University School of Medicine (BUSM) and the Laser and Skin Cancer Center of Indiana, (Carmel, Indiana), found that there has been a dramatic increase in the number of procedures performed and patient demand for dermatologic health care since 2000. view more (2009-10-06)
Plant fossils give first real picture of earliest Neotropical rainforests
A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago. view more (2009-10-16)
International research centre moves a step closer
The University of Sunderland has received more than £500,000 to help create its International Photography Research Centre. view more (2004-09-27)
MIT: Oceans are a major gene swap-meet for plankton
New evidence from open sea experiments shows there's a constant shuffling of genetic endowments going on among tiny plankton, and the "coinage" they use seems to be a flood of viruses, MIT scientists report. view more (2006-03-24)
New study finds that sharing genetic resources key to adaptation to climate change in Africa
As rapidly rising temperatures in Africa threaten to scorch local varieties of maize and other food staples, the food security of many Africans will depend on farmers in one country gaining access to climatically suitable varieties now being cultivated in other African nations, and beyond. view more (2009-06-18)
Misclassified for centuries, medicinal leeches found to be 3 distinct species
Genetic research has revealed that commercially available medicinal leeches used around the world in biomedical research and postoperative care have been misclassified for centuries. view more (2007-04-12)
Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. view more (2007-03-29)
Cracking the egg
Sexual reproduction is not necessarily sexy (especially when scientists start analyzing it), but it is fascinating. As we all know, the basics entail bringing together an egg and a sperm, a whole lot of cell division and growth, and sooner or later a young organism that carries a mix of genes from both parents. view more (2006-10-04)
Frozen hair holds secrets of Yellowstone grizzlies
Locks of hair from more than 400 grizzly bears are stored at Montana State University, waiting to tell the tale of genetic diversity in the Yellowstone Ecosystem. view more (2007-12-19)
