New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...ium-239, the hazardous isotope produced in nuclear power plants, he said. The bacteria Pseudomonas pavonaceae have evolved in the soil in which the potato pesticide 1, 3-dichloropropene is used and can grow on it as their only source of carbon and energy, the scientist said. The enzyme responsible for deg...

Plants reveal a secret and bring researchers nearer a cleaner future

Using sunlight to power our homes and offices is an unaccomplished dream d.... How far away are we then from using the sun to power our daily lives? Michael Haumann, the main author of the publication, asserts that "these are import...

Bone marrow stem cells may heal hearts even years after heart attacks

Researchers find ways to turn manure into power

... paved with fly-ash, a byproduct of the coal-fired power generating industry, and the other manure was from unpaved pens. The manure was composted and test results from the two showed a large difference for several constituents measured, especially ash content, Sweeten said. Ash, an unusable material as f...

UW-Madison scientists zero in on drugs' sweet spots

...simple new technique to manipulate the sugars that power many front-line drugs, a team of Wisconsin scientists has enhanced the antic-cancer properties of a digitalis, a drug commonly used to treat heart disease. Reporting the work in the Aug. 8 edition of the Proceedings of the National Academy of Scienc...

Fish and chips: A fast track to understanding blood development

...brings researchers a step closer to harnessing the power of stem cells for disease treatments. Every day, blood stem cells divide and differentiate to generate approximately 200 billion new blood cells in the bone marrow of adults. To maintain their numbers over time, blood stem cells also can divide and ...

Molecular trigger for Huntington's disease found

.... This abnormal gene activation damages the cells' power plants, called the mitochondria, and kills brain cells. The researchers also speculated that disturbances in p53 may also play a role in some forms of Parkinson's disease and amyotrophic lateral sclerosis, or Lou Gehrig's disease. Ironically, p53 i...

Vaccine targets tumors where they live

...oblem is that the T cells lose their tumor-killing power once they reach the environment surrounding the tumor. This happens because T cells decrease stimulatory molecules including one called B7.1. In a study appearing online on June 2 in advance of the print publication of the July 1 print issue of the ...
