Soil fertility limits forests capacity to absorb excess CO2.

...forest response to atmospheric CO2. "Trees can sustain increases in biomass only as long as they find enough water and nutrients in their ecosystems," Ellsworth said. "I don't think we can assume existing forests, with their fertility limitations, will completely offset rising CO2 without soil amendment...

Amazon rainforest could be unsustainable within a decade

...push the rainforests past the point where they can sustain themselves a lot sooner than many people think. The other key tropical rainforests are in the Congo River Basin in Africa and Southeast Asia. To use the two-million-square-mile Amazon River Basin as an example, Alcock said his model shows that if...

Vaccination following spinal cord injury: Innovative Weizmann Institute approach limits paralysis

...e United States alone, approximately 10,000 people sustain a spinal cord injury each year. More than half of these injuries are classified as incomplete, or partial, meaning that some nerve fibers survived the initial trauma. If the surviving tissue could be protected against secondary degeneration, this wou...

UNC scientists develop new way to calculate stability of proteins

...ction of a protein depends on the fact that it can sustain the same structure over an extended period of time," Carter said. "Thus, for purposes of drug design, the whole area of protein engineering is highly dependent on knowing the contributing factors that make a protein stable." Getting to know a prote...

Yale researchers develop first microarray chip for complete analysis of proteins

...which interacts with other proteins to develop and sustain cell life. Prior to the Yale scientists' discovery, studying proteins on a large, nearly complete scale had never been done, and many scientists believed it was not possible.

Scientists identify cells necessary for tumor angiogenesis

...roteins, Id1 and Id3, are necessary to support and sustain tumor angiogenesis. In this study, Id-deficient mice were transplanted with bone marrow cells from donor wild-type mice (normal mice) that were marked with a protein (B-galactosidase+), which allows them to turn blue when stained with a specific dye...

UMass researchers find environment on Earth that mimics Mars geochemically and supports ancient life form

...here is no sunlight. So, if there is life, it must sustain itself with alternative energy sources. This study demonstrates, for the first time, that certain microorganisms can thrive in the absence of sunlight by using hydrogen gas released from deep in the Earths surface as their energy source.
