FDG PET detects thyroid cancer better than conventional imaging
FDG PET detected recurrent cancer 50% more often than did conventional imaging in persons suffering from thyroid cancer who had indications that their cancer had recurred, according to results of a study published in the October issue of The Journal of Nuclear Medicine.

Scientists image material that could improve MRI technologies
Using a technique similar to the magnetic resonance imaging (MRI) widely applied by hospitals for medical diagnosis but at a resolution 10,000 times greater, physicists at Northwestern University have gained insights into a high-temperature superconductor that might one day benefit hospital MRI technologies and the patients who rely on them.

Iron-deficient children at risk for higher blood lead levels, finds researchers at UC Berkeley
Researchers from UC Berkeley and the California Department of Health Services found that young children who were iron-deficient had significantly higher blood lead levels than children with normal blood iron levels.

University of Florida researchers laser mapping WTC, Pentagon sites
Faculty and students in the University of Florida's civil and coastal engineering department are part of a multi-agency collaborative effort to use an entirely new technique to get detailed pictures of the World Trade Center and the Pentagon that relies on both airborne laser swath mapping, or ALSM, and ground-based scanning laser technology.

The acoustics of laughter
Studying laughter episodes in young adults watching funny video clips, Vanderbilt and Cornell researchers have made several surprising findings about these outbursts of merriment.

Georgetown research uncovers new mechanism for suppressing HIV
Laboratory studies at Georgetown University Medical Center have shown that Peptide-T -- a synthetic compound of amino acids -- can suppress the human immunodeficiency virus (HIV) by preventing the virus from entering healthy human cells.

NIH funds biomedical research infrastructure networks
The National Institutes of Health (NIH) announced today that it has awarded 24 grants, totaling approximately $45 million, to biomedical research institutions located in states that have not fully participated in NIH grant funding in the past.

Lessons for the future from 'most thorough' analysis of Foot and Mouth epidemic yet
A new analysis of the spread of Britain's Foot and Mouth disease epidemic shows that extended culling programmes were essential for bringing the epidemic under control.

Scientists build case for 'haplotype' map of human genome, find new gene for Crohn's disease
In companion papers, researchers report findings that set the stage for the next steps in the Human Genome Project--mapping and identifying all the genes that predispose us to common diseases.

Researchers pinpoint cause of deadly blood-clotting disorder
HHMI researchers have determined the cause of a potentially deadly inherited blood-clotting disorder that can lead to kidney failure or stroke.

Cardiac hormone level indicates increased risk of death, progression of heart failure, researchers report
Researchers at UT Southwestern Medical Center at Dallas have found that elevated levels of a cardiac hormone is predictive of an increased risk of death or heart failure in patients with complications of coronary artery disease.

Say two prayers and call me in the morning
A recent study at Saint Louis University found that although most physicians agree there is a link between religion and healing, only 8 percent discuss spirituality with their patients in detail.

Drop of 30 percent in use of animals in some chemical tests could be quickly achieved through use of cells, US says
U.S. scientists are reducing the number of rodents in chemical safety testing to a fraction of the 50 to 200 animals used in the old LD50 test for toxicity, but the use of human or animal cell lines could reduce the number of animals further.

Deadly copper disease in infants targeted
Cells in the placenta, brain and intestine are linked to Menkes' disease in babies, researchers at the Texas Agricultural Experiment Station discovered.

The flowering of a new industry
As water quality, pollution and salinity threaten traditional crops along the Murray, Australia's largest river, research scientists are developing Australian native flowers as a sustainable crop for floriculture.

Northwestern researcher discovers second gene for Lou Gehrig's Disease
A second gene mutation that causes an inherited form of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, has been identified by Teepu Siddique, M.D., the Northwestern University researcher who, with collaborators from Massachusetts General Hospital, discovered the first ALS gene (ALS1) in 1993. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
