Tiny particles could solve billion-dollar problem

...llions of dollars. The Department of Defense alone estimates the cost of bringing its 1,400 TCE-contaminated sites into EPA compliance at more than $5 billion. The typical approach to getting rid of TCE involves pumping polluted groundwater to the surface, where it can be exposed to chemical catalysts or micr...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

...ces cost and time factors drastically. Gao’s group estimates thatthe new technology will be about one hundred times more cost- andtime-efficient than current technologies.With this discovery, Gao and her colleagues have developed a technologywith the potential to make complete functioning organisms that canpro...

New Clues Add 40,000 Years to Age of Human Species

... ago, say the researchers, an age that agrees with estimates from genetic studies for the age of the last, common Homo sapiens ancestor, and reinforcing evidence that most of human history transpired in Africa. The study was funded by the National Science Foundation, the L. S. B. Leakey Foundation, the Nati...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...onal Institute of Dental and Craniofacial Research estimates 80 percent of adult Americans have some form of periodontal disease, their symptoms ranging from mild gum irritation to complete tooth loss. People with periodontal disease also are at increased risk of stroke and heart attack, and the disease makes...

US life expectancy about to decline, researchers say

...torical trends, but the authors conclude that such estimates fail to consider the obesity epidemic. Olshansky ...f-life-lost due to obesity and combining that with estimates of the prevalence of obesity in younger generations, the authors were able to illustrate that in the...

Cricket's finicky mating behavior boosts biodiversity

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

...is no public registry of animal researchers, Welch estimates that there may be as many as 12,000 academic and private animal imaging labs in the world and that more than 200 may do small animal PET routinely. Through small animal imaging research, Welch and his researchers gained more of an understanding abou...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

...cess “more predictable and less costly.?The latest estimates put the cost of bringing a new product to market at $1.6 billion to $1.8 billion. UF researchers are working on an approach known as PK/PD, which combines principles of pharmacokinetics, or an analysis of drug concentrations in the body, and pharmac...

Researchers find new genes necessary to make embryo

...n of genes, the researchers almost double previous estimates of how many genes are required to make an embryo. Their study focused on the genes expressed by the mother and imparted to the egg, ready to be used during the earliest stages after fertilization. They discovered over 150 additional genes required to...

New Estimates For The Causes Of Child Deaths Worldwide

The most accurate estimates of the causes of child deaths to date, published i... and ongoing studies in 2000 to 2003 to obtain new estimates for mortality by cause in children younger than age 5 years. They found the four communicable diseas...

Test for early detection of prostate cancer shows promise

...found in American men. The American Cancer Society estimates that there will be approximately 232,090 new cases of prostate cancer in the United States in 2005, and 30,350 men will die of this disease. Funding for the study was provided by Tessera Inc. Other authors on the report are Barbara Paul, Rajiv Dhir,...

Study: 'homemade' gene expression technology unreliable

...effects of drugs and chemicals," said Spencer, who estimates there are "hundreds, if not thousands" of laboratories around the country using DNA microarrays. Microarray platforms came into widespread use about five years ago. Pioneers in the field constructed their own gene chips, but these have now been repl...

New World founders small in number

...New World at around 14,000 years ago. Though Hey's estimates are more recent, they also indicate a high probability at this time period. With this new approach, researchers will be able to explore this and many other questions to fill in the details of the first American immigration. Citation: Hey J (2005) On...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...nsive than treating normal infections, and the WHO estimates the total cost of treating all hospital-borne antibiotic resistant bacterial infections is around $10 billion a year. Worse, with modern rapid transit and world travel, multiple drug-resistant bacteria could potentially spread beyond the isolated con...

This research is part of Food Animal Production, an ARS National Program (#101) described on the World Wide Web at www.nps.ars.usda.gov. Harvey D. Blackburn and Ph...

$5.1 billion would save 6 million children

...ymakers, donors and governments will use our price estimates to strengthen their health systems. If they don't, 16,000 children will continue to die each day as a result," said Jennifer Bryce, EdD, lead author of the study. This study follows a series of articles by Black, Bryce and their colleagues, publishe...

Fragile US vaccine system needs improvement despite dramatic gains in health over past century

...lability of vaccines for children. The most recent estimates (2000) of the cost to develop a new vaccine range from $110 million to $802 million, and five vaccines recently reviewed by the National Vaccine Advisory Committee took from two to twenty-one years from Phase I clinical trials to licensing. Safety c...

Late peak may have prevented severe flu season from becoming worse

...ACTrackerTM, an online tool that provides national estimates of hospital and drug utilization approximately 45 days after the end of each month, making the estimates the most timely and current of their kind. In the 2004-2005 flu season, daily CAP discharges peaked...

Scripps research scientists identify infertility molecule

...se. The American Society for Reproductive Medicine estimates that the cause of infertility remains a mystery in about 20 percent of all cases. One issue may be that once a woman's egg is fertilized and made into an embryo, it must descend to the womb and implant there, where it will grow into a fetus. But the...

Malaria killing a million a year

The report estimates that 350 million to 500 million people worldwide contract malaria per year, up somewhat from the estimate of 300 million to 500 million cases annually that WHO has been using since 2001. "Current methods do not allow for a more precise estimate, giv...
