The Journal of Rehabilitation Research and Development (JRRD) has compiled a compendium of articles describing advances in limb loss and prosthetics research published in 2004.

American Academy of Microbiology report proposes initiative to interpret genome data
While large-scale genomic sequencing technologies over the past decade have given scientists databases filled with the complete genomes of hundreds of organisms, not enough is being done to interpret all that data by assigning functions to sequenced genes (annotation), according to a report released today by the American Academy of Microbiology.

Brenner Children's Hospital named to NIH Pediatric Heart Network

Study shows drugs such as Vioxx and Celebrex were widely over-used long before recent problems
Before drugs such as Vioxx and Celebrex were connected to heart attacks, there was concern that these drugs were over-used, often by patients unlikely to benefit from this type of medication.

Timing is everything: First step in protein building revealed
Timing is everything, it seems, even in science. A team led by Johns Hopkins scientists has unraveled the first step in translating genetic information in order to build a protein, only to find that it's not one step but two.

More science and engineering doctoral degrees awarded in 2003
After a 1998 high, the number of science and engineering (S&E) doctorates awarded by U.S. institutions has been declining.

Evolution of classical polyandry: three steps to female emancipation
Emancipation Classical polyandry occurs when female breeds with several males who raise their offspring alone.

Queen's physicist first Canadian to win top Russian science prize
Queen's University Physics Professor Art McDonald is the first Canadian to win the prestigious international Bruno Pontecorvo Prize in elementary particle physics, Russia's top award in this field.

Severity of liver disease not a reliable indicator of quality of life
A new study on the determination of how livers are allocated for transplants examined the relationship between liver disease severity and quality of life, and found that the commonly used model for liver allocation is not a reliable indicator of general quality of life.

Revolutionary new medical treatments: International effort to steer around obstacles
Major developments in biotech, genomics and stem cell research now offer exciting and far-reaching new opportunities for health care in conditions ranging from Alzheimer's and Parkinson's disease to genetic disorders.

Microbiologist named National Associate of National Academies
The nation's premiere science advisory organization has bestowed its National Associate honor on University of California, Riverside Professor of Environmental Microbiology, Marylynn V.

Childcare provision is not geared to realities of modern working life
For most of the growing number of women who go out to work, organising childcare for young children is a highly complicated process in which the slightest disruption is likely to cause a crisis, according to new research sponsored by the ESRC.

Anti-bacterial additive widespread in U.S. waterways
Researchers at the Johns Hopkins Bloomberg School of Public Health estimate that many rivers and streams in the United States contain a toxic antimicrobial chemical.

DNA molecules used to assemble nanoparticles
University of Michigan researchers have developed a faster, more efficient way to produce a wide variety of nanoparticle drug delivery systems, using DNA molecules to bind the particles together.

Abused women less likely to be in stable relationships
Poor women who are physically or sexually abused at some point in their lives are less likely to maintain stable intimate relationships, according to a new study.

Molecular scale resolution achieved in polymer nanoimprinting technique
Scientists using molds derived from carbon nanotubes have approached the ultimate resolution -- defined by molecular scale dimensions -- in a widely used polymer nanoimprinting technique.

Vioxx went mostly to patients who didn't need it, Stanford researcher says
A new study shows that millions of people who had little risk of gastrointestinal bleeding ended up getting prescriptions for Vioxx, Celebrex and other medicines in their class, known as COX-2 inhibitors.
