Report highlights change in Canada's forests

... competition. The report also focuses on important advances in forest management in 2005?006 as governments sought to balance environmental, economic and social factors affecting Canada's forests. "The future health of the forest industry will depend on how well we care for this resource, how efficient we ar...

UCSD study reveals how plants respond to elevated carbon dioxide

...ity of California, San Diego have made significant advances toward understanding the mechanism plants use to regulate their carbon dioxide intake. The study, published in the May 1 early on-line edition of the journal Proceedings of the National Academy of Sciences, shows how the level of carbon dioxide in ...

Melatonin improves mood in winter depression

...ients is bright light exposure, which causes phase advances when scheduled in the morning. Because patients know when they are exposed to bright light, however, there is a considerable placebo response associated with it. Melatonin can also cause phase advances, but it has to be taken in the afternoon. The Le...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

...r unavailable to atmospheric processes. Dramatic advances in understanding how these plankton work have developed in the past few years with the availability of new genomic data. The scientists searched genome fragments of these plankton, looking for specific gene sequences that would show how the plankton ...

Gut reaction: Researchers define the colon's genome

...lants, such as apples and carrots. The new study advances the growing field of metagenomics, or the study of many genomes found in a given ecosystem. Scientists at TIGR and elsewhere have recently scooped up whole environmental samples, from soil to sea, to study the diverse genomes contained within them. T...

New study calculates millions of years saved in lives of AIDS patients

... those years into "eras" corresponding to specific advances in AIDS care, and then used the simulation model to determine per-person survival time for each era, compared to the absence of treatment. The results: Per-person survival increased by three months in 1989-92 and then by two years in 1993-95; both e...

Study defines effective microbicide design for HIV/AIDS prevention

...livery system and applicators." However, he added, advances made through continued research on new and better drugs should not be discounted. In addition to their role in drug delivery, microbicide formulations can act as physical barriers or filters to slow HIV's passage from semen into body tissues, Geonn...

Embryos exposed in 3-D

Biofuels researcher searches for new sources

...y, said in a recent email that rapid technological advances in the production of such cellulosic ethanol are contributing to its tremendous potential as an easy-to-use fuel in conventional vehicles. How best to bring that tremendous potential to Montana is just what Chen and his collaborators are researchin...

Speeding the search for elusive chromosomal errors

...telomeres, at the end of each chromosome. Recent advances in diagnostic gene chips, used by Dr. Shaikh's team, allow more precise analysis of very small DNA alterations throughout all of a patient's chromosomes. Gene Chips Detect Tiny Structural Defects in Genomic Diseases Conditions that originate in a...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

Somerville presented his talk, "Bioenergy: The 21st Century Challenge to Plant Biolog...

Brain-computer link lets paralyzed patients convert thoughts into actions

...ges using assistive software. "We believe these advances could ultimately enable a paralyzed person to control communication devices, medical devices, computer-controlled robotics, wheel chairs ?and even their own limbs," said Cyberkinetics's Surgenor. "As a physician," said Harvard's Leigh R. Hochberg,...

New GI technologies improve internal organ visualization

...nimally-invasive techniques represents significant advances in the practice of medicine. In this study, researchers review the technical challenges and potential value of an endoscopic ultrasound (EUS)-guided angiography. Endoscopic ultrasonography is the practice of using an ultrasound transducer at the t...

On the track of tiny larvae, a new model elucidates connections in marine ecology

...ugh tiny larvae are impossible to follow directly, advances in modeling ocean currents have made it possible to predict larval movements. However, until now it has remained difficult to test these movement predictions in the field by comparing the model to data from population genetic studies. The new work...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

Critical advances in medicine and environmental protection promise to emerge from a new method for biochemical analysis of fluids developed by an international science team led in part by Arizona State University researchers. Called "digital magnetofluidics," it pro...
