X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

... molecular changes in the powerful muscles as they lengthen and shorten to drive the wings back and forth 200 times each second. “At the molecular level, the insect’s flight muscle and a human heart are remarkably similar,?Maughan said. “We biologists have always been amazed by how hard these muscles work. N...

Chemical 'band-aid' prevents heart failure in mice with muscular dystrophy

...cytes in dystrophin-deficient mice don't relax and lengthen as readily as cardiac myocytes in normal mice. They are stiffer than normal heart muscle cells, and vulnerable to damage when stretched. "That's where poloxamer 188 comes in," Metzger adds. "It assists the heart to be more compliant during the relax...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

...ue to raise temperatures in the region and further lengthen the snow-free period each year. Since the early 1960s, scientists have identified "hotspots" of slowly increasing average summer temperatures in the Arctic, from 0.15 degrees Celsius to about 2 degrees Celsius for an average increase of 1.2 degree...

New antifreeze protein found in fleas may allow longer storage of transplant organs

...y snow fleas by Queen's University researchers may lengthen the shelf life of human organs for transplantation. Drs. Laurie Graham and Peter Davies, from the Department of Biochemistry, found that the potent protein produced by the fleas to protect themselves against freezing is capable of inhibiting ice gro...

Human trial proves ricin vaccine safe, induces neutralizing antibodies; further tests planned

...e vaccine with an adjuvant, a formulation that may lengthen the time the vaccine is effective. An adjuvant, such as alum, is an ingredient that enhances the immune response of a stand-alone vaccine. Other common vaccines, such as tetanus, are typically administered with an adjuvant and can confer immunity for...

New fMRI technology making brain tumor surgery safer

...s.? The need for electrical stimulation also can lengthen a surgical procedure by 30 to 60 minutes. While neurosurgeons make the transition to the fMRI-assisted navigation technology, they are continuing to perform brain stimulation to double-check for accuracy. Thus far, Dr. McPherson said, the double c...

New test for most virulent HPV strains under study
