Gertzman, executive vice president for research and development at the Musculoskeletal Transplant Foundation. Other scientists have attempted to invoke a similar reaction in dead bone by infusing tissue-grow...

Different microarray systems more alike than previously thought

...if the technology changes or people make different choices in their platform." When the study began roughly two years ago, microarray platforms were an exciting technology in the medical and biological sciences, but comparisons of results from different platforms had proved inconsistent. Previous studies in...

A puzzle piece found in unraveling the wiring of the brain

...at is required for nerve cells to make appropriate choices of targets on which to act. The Sec15 protein is part of a protein complex (the exocyst) which is known to be required for secretion (or exocytosis) of vesicular compartments in yeast. Vesicular compartments are small organelles that transport prote...

Evolution of taste receptor may have shaped human sensitivity to toxic compounds

... It is widely believed that behavioral and dietary choices may have reduced the importance of such chemical perception in higher primates, and particularly in humans. In new work, researchers including Nicole Soranzo of University College London and Bernd Bufe of the German Institute of Human Nutrition have...

Bumblebees copy one another when contending with unfamiliar flowers

...choose flowers entirely alone but instead copy the choices of other bees. The new findings suggest that bees adjust their behavior when dealing with flowers of unfamiliar plant species. The observations are reported in the June 21 issue of Current Biology in a new paper by Elli Leadbeater and Lars Chittka o...

Expanding forests darken the outlook for butterflies, study shows

...ns in the Canadian Rockies are stifling the mating choices of butterflies in the region, say University of Alberta researchers. Smaller and less abundant alpine meadows--largely the result of human activities--are diminishing the alpine butterfly gene pool, creating a pattern that could lead to the butterfl...

Emerging staph strains found to be increasingly deadly and deceptive

...because of antibiotic resistance, which limits the choices for treatment. But the situation can become more serious with the newer community-acquired strains, says Dr. DeLeo. "We do not know why cases of community-acquired MRSA infections are increasing, let alone how they flourish," he says. But scientists ...

Plants, too, have ways to manage freeloaders

"We may have bred this ability out of our crops." Simms and her colleagues, including D. Lee Taylor, a former UC Berkeley post-...

Study finds that nutritionally enhanced rice reduces iron deficiency

... vegetables and meat, but, for the very poor, such choices are simply not possible and so they depend predominantly on staple foods to stave off day-to-day hunger. This is especially true in isolated rural areas where under-resourced and overstretched public health systems struggle to improve the overall nu...
