Research effort seeks A's to gene expression Q's
...asurements of gene activity. But the technology is beset by large uncertainties and unexplained variability in measurement. One experiment using three different microarray systems to measure the same sample found that under the most stringent criteria the three agreed on only four out of 275 genes identifi...No small feat: First ever gene therapy success for muscular dystrophy achieved
...ied approaches for muscular dystrophy, it has been beset with uniquely difficult hurdles. The genes to replace those that are defective in CMD are larger than most, so it has not been possible to apply the same methods successfully used for delivering other types of genes. And because CMD affects all muscl......giants that roamed Earth 75 million years ago were beset by stomach worms. The evidence was found in an exceptionally well preserved duck-billed dinosaur dug from the rocks of the Judith River Formation near Malta, Mont. Assistant Professor Karen Chin of CU-Boulder's geological sciences department and f...New study warns against linking ethnic identity to breast cancer genes
...east cancer mutations with Ashkenazi Jews has been beset by methodological problems that cast doubt on the use of ethnicity as the basis for genetic research on disease. "The linking of Ashkenazi Jews to a deadly disease raises serious scientific and social concerns," said co-author Sheila M.

... tradeoff. But it is precisely these ants that are beset by parasitoid flies which lay their eggs specifically on these types of ant, eventually causing a gruesome death by decapitation. When the target ants see the flies hovering around, they run away and are unable to effectively defend resources. Using ...New weather, old pipes challenge nation's water supply
...predictable weather conditions produce floods that beset the nation, a Michigan State University water expert says. The nation needs better ways to monitor the safety of drinking water, Joan Rose, MSU's Nowlin Chair in water research, told the American Association for the Advancement of Science annual me...AAAS panel will focus on the impact of livestock production on the planet
...at intensive and extensive forms of production are beset with a range of different problems. In "intensive systems," animals are contained and feed is brought to them. "Extensive systems" generally refer to grazing animals that live off the land. "Extensive livestock production plays a critical role in l...Massive herds of animals found to still exist in Southern Sudan

The significance of this find and the critical juncture we are seeing in the development of Southern Sudan require an intensified effort in the area of natural resource conservation, particularly wildlife, said Brian DSil......d as a replacement for bone grafting, which can be beset by problems which include a short supply of host bone, chronic post-operative pain, and an increased risk of infection.
