Value of services performed by insects tops $57 billion in US

...million a year. And these are "very conservative" estimates that probably represent only a fraction of the true value, reports Losey, associate professor of entomology at Cornell. This analysis of the economic value of these insect services is the first analysis of its type, said Losey, who co-authored the s...

...om the condition. The U.S. Alzheimer's Association estimates that by 2025, over 22 million people worldwide will be afflicted. According to a report commissioned by the U.S. Alzheimer's Association, AD costs American businesses approximately US$61 billion a year. That price tag includes US$24.6 billion for di...

Cincinnati surgeons report new treatment for often-fatal injury

...edition of Annals of Vascular Surgery. Dr. Giglia estimates that 80 to 90 percent of the patients who suffer this injury--known as blunt thoracic aortic trauma--die before ever reaching a hospital. The aorta is the main artery that carries oxygenated blood from the heart to be distributed throughout the body...

Scientists find Antarctic ozone hole to recover later than expected

...hole area." For the first time, a model combines estimates of future Antarctic chlorine and bromine levels based on current amounts as captured from NASA satellite observations, NOAA ground-level observations, NCAR airplane-based observations, with anticipated future emissions, the time it takes for the tran...

NASA study solves ocean plant mystery

...ction for this "iron-effect" decreases scientists' estimates of how much carbon ocean plants photosynthesize for the region by roughly two billion tons. This figure represents a tremendous amount of carbon that remains in the atmosphere that scientists previously thought were being removed. The results about...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...ans experience heartburn at least once a month and estimates are that more than 15 million suffer from it daily. For the great majority of those sufferers, Gerson's recent findings could free them from the bonds of dietary self-denial. She is considering doing studies of her own to learn more about what effect...

Study reveals how ADHD drugs work in brain

...ncentrate. The National Institute of Mental Health estimates that 2 million children in the U.S. suffer from the condition, with between 30 to 70 percent of them continuing to exhibit symptoms in their adult years. Despite public anxiety over the treatment of a behavioral condition with pharmacological drugs,...

New genetic test for breast cancer

...d on or off in the tumor. This genetic assessment estimates a patient's risk of recurrence more precisely than standard clinical characteristics, such as tumor size and grade. It also helps predict whether a patient will benefit from chemotherapy. "This test yields what is called a recurrence score. For a...

Bird flu study highlights need to vaccinate flocks effectively

...ls are usually much lower than this. The new study estimates that protection levels of more than 95 per cent would be needed to guard against silent spread. The study, funded by the Department of Environment, Food and Rural Affairs, suggests that the most effective way of tackling silent spread of the diseas...

NHGRI announces latest sequencing targets

...be fully sequenced, genomic information will allow estimates of future disease risk for individuals, as well as improve prevention, diagnosis and treatment. Projects given the highest priority will use large-scale sequencing over the next few years to identify the genes responsible for dozens of...

New findings offer more complete view of breast cancer gene mutations in US population

...population-based study are compatible with earlier estimates made by extrapolating from smaller studies. However, we found a slightly lower frequency of BRCA1 mutations and a higher frequency of BRCA2 mutations," said the study's other lead investigator, Kathleen Malone, Ph.D., Member of the Public Health Scie...

How healthy is that marsh? Biologists count parasites

... The results proved encouraging as the video-based estimates of the bird community were in close agreement with those from the snail-trematode analysis. "The more birds there were at a site, the more parasites," Hechinger said. "The more kinds of birds, the more kinds of trematodes, just as we predicted." He...

...protection, and so on--supports human welfare, and estimates its value in economic terms. Now, Costanza and his colleagues at UVM's Gund Institute for Ecological Economics have launched a project to solve a central problem that this young science faces: creating a fast way for policy-makers to understand the...

Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters

...eral days. Despite massive clean-up efforts, Short estimates about six miles of shoreline is still affected by the spill and as much as 100 tons of oil lingers in the Sound. In their study, Short and his colleagues found significant amounts of Exxon Valdez oil buried in sand and silt that only becomes dry du...

NYU algorithm enhances ability to detect cancer genes

...rogresses to an advanced stage. The NYU algorithm estimates the location of tumor suppressor genes by analyzing segmental deletions in the genomes from cancer patients and the spatial relation of the deleted segments to any specific genomic interval. Since the gene-chip consists of many "probes"--each one cha...

The American Cancer Society estimates that 18,510 new cases of primary livercancer and bile duct cancer will be diagnosed in the United States during2006, and around 16,200 people will die of liver cancer. Studies in mice by Zhi Yuan and his team at Nankai University, China, revealed th...
