Cold is hot in evolution — UBC researchers debunk belief species evolve faster in tropics
University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates. view more (2007-03-16)
Scientists use lasers to measure changes to tropical forests
New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. view more (2009-01-26)
New bacteria contaminate hairspray
Scientists in Japan have discovered a new species of bacteria that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology. view more (2008-03-10)
Ecological globalization
Ecosystems are constantly exchanging materials through the movement of air in the atmosphere, the flow of water in rivers and the migration of animals across the landscape. view more (2008-06-02)
CT angiography highly accurate, multicenter trials show
Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2007-11-27)
Biodiversity and resilience of coral reefs
With over 3000 fish species, Indo-Pacific coral reefs represent one of the most diverse ecosystems on the globe. It is easy to assume that the loss of one or two species from these systems would have little impact. However, in an article in the April issue of Ecology Letters, Bellwood and colleagues document major changes in Indo-Pacific coral... view more... (2003-04-08)
Holy Guacamole: NC State Researcher Tracks Invasive Beetle Threatening Florida's Avocados
A researcher at North Carolina State University is tracking the movement of the Redbay Ambrosia beetle, an invasive insect that, if it spreads to southeast Florida, may severely affect the production of avocados, a $15 million to $30 million industry in the state. view more (2009-02-05)
Assessing levies for accidental by-catch, say researchers, could generate money to protect threatened species
Fishing industry lines accidentally catch so many seabirds and turtles that their populations are being threatened. One solution offered by a Cornell researcher and an Australian government scientist is to assess fines when threatened species are caught and killed. view more (2007-07-19)
Researchers at Vanderbilt-Ingram Cancer Center uncover clue to explain invasive brain tumors
Researchers at the Vanderbilt-Ingram Cancer Center have uncovered a clue to explain the invasive nature of an aggressive kind of brain tumor called glioblastoma multiforme, or gliomas. view more (2006-01-12)
Invasive sea squirts persist on Georges Bank
For the fourth consecutive year, federal and university researchers have surveyed two areas on Georges Bank where an invasive colonial sea squirt continues to thrive on the gravel bottom. view more (2006-09-21)
In Large-Scale Study, NC State Scientists Show Landscape Corridors Promote Plant Diversity By Preventing Species Loss
Landscape corridors - thin strips of habitat that connect isolated patches of habitat - are lifelines for native plants that live in the connected patches and therefore are a useful tool for conserving biodiversity. view more (2006-09-01)
Lemurs' fur color may not define species
Different coat colour might not correspond to different species for nocturnal lemurs. In a study published today in the open access journal BMC Evolutionary Biology, researchers find that lemurs that appeared to belong to different species because they have strikingly different coat colours, are in fact genetically related and belong to the same... view more...

Animals that seem identical may be completely different species
Animals that seem identical may belong to completely different species. This is the conclusion of researchers at the University of Gothenburg, Sweden, who have used DNA analyses to discover that one of our most common segmented worms is actually two types of worm. The result is one of many suggesting that the variety of species on the earth could... view more... (2009-04-23)
Although more older women receive breast-conserving therapy, gaps in treatment exist
According to a new study published in the October issue of the Journal of the American College of Surgeons, although breast-conserving surgery (BCS), commonly known as lumpectomy, is increasingly being used to treat older women with nonmetastatic invasive breast cancer, there are still significant socioeconomic and geographic disparities in the... view more...

Worldwide distribution of cervical cancer virus is consistent with vaccine targets
The variety of human papilloma viruses that cause invasive cervical cancer cases worldwide are largely consistent across continents, according to a new study from the University of North Carolina at Chapel Hill. view more (2007-08-02)
Sharks in danger
There are 370 species of shark, each with their own particular habitats and behaviours. Most sharks are slow to reproduce and do not have large numbers of young. They are therefore particularly sensitive to predation or large losses. Caught as accidental by-catch (estimated at 3000 per day), sharks are also fished for their fins (for food),... view more...

Report Documents the Risks of Giant Invasive Snakes in the U.S.
Five giant non-native snake species would pose high risks to the health of ecosystems in the United States should they become established here, according to a U.S. Geological Survey (USGS) report released today. view more (2009-10-14)
Chemical come-on successfully lures love-sick lampreys to traps
A synthetic chemical version of what male sea lampreys use to attract spawning females can lure them into traps and foil the mating process of the destructive invasive species, according to Michigan State University scientists. view more (2009-01-22)
New species of diatom discovered
In the latest issue of Diatom Research, the scientists describe a new species of diatom, Hannaea superiorensis, found primarily in Lake Superior view more (2005-12-05)
Mayo Clinic study finds increased risk of pneumococcal disease in asthma patients
Mayo Clinic research shows adults with asthma are at increased risk of serious pneumococcal disease caused by Streptococcus pneumoniae, the most common bacteria causing middle ear infections and community acquired pneumonia. view more (2008-12-22)
