'Dead zone' area shrinking, Texas A&M prof says
... extremely low. The dead zone has been studied and tracked since it was discovered 20 years ago, DiMarco says. "We need to do some further research to determine the specific mechanisms under which hypoxia is created, maintained, and ultimately dissipated," he believes. DiMarco will present his findings next ...Cardiac arrest may hinder ability to learn certain tasks
...er-wide tank to find the platform. The researchers tracked how long it took each mouse to reach the platform, as well as how fast and how many meters the animal swam during its search. By the end of this training phase, each mouse had learned where the platform was and could swim to it directly regardl...UCI scientists successfully target key HIV protein; breakthrough may lead to new drug therapies
...acterium), which provided a 'handle' that could be tracked by the researchers to determine whether Nef was binding to three cellular proteins, as is Nef's function. (Although Nef is able to bind well to the three proteins in the absence of the bacteriophage, the researchers used the bacteriophage simply as a...9/11 search-and-rescue dogs exhibit few effects from exposure to disaster sites
.... For the last three years, the Penn researchers tracked the health of dogs and handlers from the World Trade Center, the Pentagon and the Fresh Kills Landfill site on Staten Island, where debris from the World Trade Center was further searched. "Overall, the lack of clear adverse medical or behavi...IBD (Crohn's/ulcerative colitis) conference adds 18 speakers; APS meeting starts Thursday
... CCFA noted that a large HMO tracked IBD-related hospitalizations over six years and reported exactly the same rates for whites and blacks, 10.2 per 100,000 admissions. The hospitalization rates for Hispanics and Asians were lower at the HMO. Grisham said APS especia...New research shows air pollution can reduce children's lung function
...from 4th grade to 12th grade. The researchers also tracked levels of air pollutants like nitrogen dioxide, acid vapor, elemental carbon, and particulate matter in the 12 Southern California communities where the children lived. The study encompassed some of the most polluted areas in the greater Los Angeles ...... in situ hybridization techniques, the researchers tracked the levels of a number of growth-related genes. They were able to pinpoint BMP4 as a candidate for mediating growth, Chuong says. In humans, several BMPs play a role in enhancing the rates of cell division and growth and regulating major developmenta...Tiny collars fitted on youngest-ever tiger cubs

"Based on this principle, our lab is generating new biosensors that we hope will identify biomarkers associated with cancers of the lungs, brain and pancreas," Dmochowski said. "Over time, we'll be able to use MRI to detect aberrant protei...Endangered turtles' trek along ocean currents revealed by satellite
.... Starting in 1999 individual turtles were tracked using the CLS-run Argos system, based on radio-emitting tags whose position can be tracked worldwide to a maximum accuracy of 150 metres.

During the times the birds would normally be migrating, they slept about a third as much as usual and entered more quickly into RE...Traditional fishing destroys corals - new research

On one island, where scientists tracked the starfish population explosion over one year, healthy corals began to rapidly disappear and in space of one year the cover of algae increased from one fifth of the reef to over half.

The resulting strains are called Chromosome Substitution Strains (CCSs). They developed 22 CSSs of mice, one for each of the 21 chromosomes (including the two sex chrom...OHSU researchers discover possible connection between infant hormone exposure, obesity
...in mechanisms very early in life." OHSU scientists tracked development of neurons located in a region known as the arcuate nucleus of the hypothalamus (ARH). They found that brain circuits associated with the ARH were less developed in mutant mice that lack leptin when compared to normal mice.
