Traditional fishing destroys corals - new research
...in the more lightly-fished areas. Although experts say the world's coral reefs are disappearing as fast as its rainforests, until now little has been known about how fishing disturbs the reefs' ecosystems. Project leader Dr Nick Polunin, of Newcastle University's School of Marine Sciences and Technology...Fat cells heal skull defects in mice, Stanford research shows
... from fat tissue can repair skull defects in mice, say researchers at Stanford University Medical Center. Because this type of healing process does not depend on the use of embryonic stem cells or gene therapy, it may one day allow doctors to use a patient's own unmodified cells as building blocks to hea...Children's eating patterns show 'striking' changes in two decades
...1973-74 to 52 percent in 1993-94. The researchers say they found "no associations between meal patterns and overweight status in children." They add that further research is needed to better understand the impact of dietary intakes on the increasing numbers of children who are overweight and at risk fo...Kinase backgrounder: Iressa discovery part of major kinase project at Dana-Farber

"Of course we'd ultimately like to say archaea caused disease, but it's a horse-and-cart problem right now because we haven't shown that the archaea come before the disease," Relman said. In the future, he noted, they will collect specimens repeatedly from the same spot in the subgingival...Is that plant a tortoise or a hare? Answer predicts its response to environmental change
..." Twenty years later, Reich and his colleagues can say that plants like hares and tortoises are found in every ecosystem, and so plants from boreal forest, rainforest, desert and everywhere else can be compared. For example, "hares" like aspen and birch are better able to use resources when conditions ge...The Hunter's Breath tells a story of adventure and discovery in Antarctica
