If only the weeds would keep their genes to themselves
Family can be a blessing and a curse, and never more so than in the case of crop plants and their wild relatives. These wild and weedy relatives harbor unique and beneficial genes that may no longer be found in their cultivated siblings, but they also harbor genetic traits that farmers have intentionally selected against in their domesticated... view more...

New research finds surveys of larval-stage organisms effective for measuring marine biodiversity
There is a push to document the biodiversity of the world within 25 years. However, the magnitude of this challenge is not well known, especially when it comes to vast and often inaccessible marine environments. view more (2006-05-15)
Gene study supports single main migration across Bering Strait
Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America? view more (2007-11-27)
Bacteria 'Feed' on Earth's Ocean-Bottom Crust
Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature. view more (2008-05-29)
Researchers predict infinite genomes
Ever since the genomics revolution took off, scientists have been busily deciphering vast numbers of genomes. Cataloging. Analyzing. Comparing. Public databases hold 239 complete bacterial genomes alone. view more (2005-09-23)
Size and positioning of floral anthers facilitates pollen collection by bees
Unlike moths and butterflies that are often brilliantly colored to warn potential predators that they carry toxins, flowers and the fruits they produce have brilliant colors and unusual shapes because they want to attract the attention of pollinators and frugivores who will disperse their pollen and seed, thus guaranteeing the next generation. view more (2007-07-09)
Study finds unexpected bacterial diversity on human skin
The health of our skin - one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface. view more (2009-05-29)
A new look at the state of the oceans
The current condition of the oceans, their significance as the most important resource for the world's population, and their impact on the climate will be at the centre of discussion during the seminar 'A new look on the ocean' at the Euroscience Open Forum (ESOF 2006) in Munich. view more (2006-07-17)
WHAT FACTORS FAVOUR THE ECOLOGICAL DIVERSITY OBSERVED IN ATOLL LAGOONS ?
The first step in the investigation was the mapping by remote sensing techniques of more than two-thirds of the 76 atolls of the Tuamotu archipelago. High resolution maps, which did not exist before, were then established. Using the cartographic data thus gleaned alongside morphometric parameters picked out (size and shape of the lagoons, degree... view more... (1999-04-14)
Transport Behavior of E. coli Varies Depending on Manure Source
Escherichia coli is a commonly used indicator organism for detecting the presence of fecal contamination in drinking water supplies. view more (2009-03-10)
UT Knoxville professor finds unexpected key to flowering plants' diversity
What began with an off-the-cuff curiosity eventually led Joe Williams to hang from the limbs of a tree 80 feet above the soil of northeastern Australia. view more (2008-07-29)
Genetics used to prove linguistic theories
Most comparisons of language and inherited traits consider whether genetic patterns conform with expected relationships observed by linguists. view more (2005-11-07)
Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined. view more (2006-05-16)
New small RNAs found
Dr. Kathleen Collins and a graduate researcher in her lab at UC Berkeley have identified a second RNAi pathway in Tetrahymena thermophilia - introducing a heretofore unprecedented layer of complexity to small RNA biology in unicellular organisms. view more (2005-12-16)
A Genome May Reduce Your Carbon Footprint
With the costs of genome sequencing rapidly decreasing, and with the infrastructure now developed for almost anyone with access to a computer to cheaply store, access, and analyze sequence information, emphasis is increasingly being placed on ways to apply genome data to real world problems, including reducing dependency on fossil fuel. view more (2009-05-13)
Endemism in New Caledonia palms: prime role of climate in sustaining refugia
The flora of New Caledonia is one of the richest and most unusual on Earth. On an area of just 18 000 km_ more than 3500 species of vascular plants have been recorded -80% of which are endemic. The palms, with 36 endemic species, belonging to 16 genera- 15 of which are not found anywhere else- provide a good example of this exceptional flora. Most... view more... (2001-11-23)
Researchers invent system to control and quarantine worms attacking computer networks
A new anti-worm technology developed by Penn State researchers can not only identify and contain worms milliseconds after a cyber attack, but can also release the information if the quarantine turns out to be unwarranted. view more (2007-02-09)
Biodiversity hotspots, centres of endemicity, and the conservation of coral reefs
Coral reefs are renowned for their spectacularly high biodiversity, yet there is widespread concern for their future in the face of threats from land-clearing, over-fishing and global warming. A new study published in Ecology Letters by Australian scientists - Terry Hughes, David Bellwood and Sean Connolly has shown that biodiversity hotspots on... view more... (2002-10-30)
What makes someone your sister or brother? No easy question in 2005
Researchers delving into today's complicated range of family set-ups must recognise that 'brother and sister' relationships are now about far more than blood ties and living in the same home, warns a new study sponsored by the ESRC. view more (2005-05-17)
Taxonomy for the twenty-first century
PHILOSOPHICAL TRANSACTIONS B APRIL ISSUE Taxonomy for the twenty-first century - a theme compiled and edited by Charles Godfray & Sandy Knapp Taxonomy, the description and classification of living organisms, is a science that underpins many areas of current biology. Today it is confronted with both challenges and opportunities: the... view more... (2004-04-08)
