Changing ecosystems throw scientists mega-challenges

Accelerating environmental changes have presented humanity with some significant scientific and engineering challenges, according to the new National Science Foundation (NSF) report, Pathways to the Future: Complex Environmental Systems: Synthesis for Earth, Life and Society in the 21st Century. . Among the changes the report cites are rapid shifts in climate and ecosystems, the degradation of fr...

The nude mouse tale: Omega-3 fats save the life of a terminal cancer patient

Ron Pardini is not a medical doctor. Yet he is seen as a hero by his cancer-stricken neighbor, "D.H." Pardini helped the 78-year-old after D.H. was diagnosed with terminal lung cancer. . .. The cancerous tumors found in D.H.'s lungs have shrunk to 10 percent of what they were in 2000, accord...

Researchers create pigs that produce heart-healthy omega-3 fatty acids

In diverse ecosystems, packed with wildly different species, evolution whizzes along. As different species accumulate mutations, some adapt particularly well to their environment and prosper. It happens in marine sediments, mountain forests ?and, as a new study illustrates, in precancerous tumors, too. . In a study published online today in Nature Genetics, Carlo Maley, Ph.D., a researcher at The...

Evidence for omega 3 fats less conclusive than we thought, say experts

A study published online by the BMJ today doesn't find evidence of a clear benefit of omega 3 fats on health. . .. .. Researchers analy...

Innovative method for creating a human cytomegalovirus vaccine outlined

Each year, about 40,000 children are born infected with human cytomegalovirus, or CMV, and about 8,000 of these children suffer permanent disabilities due to the virus ?almost one an hour. These disabilities can include hearing loss, vision loss, mental disability, a lack of coordination, and seizures. According to the Centers for Disease Control and Prevention, CMV is as common a cause of seriou...

LIAI scientists make important finding on cytomegalovirus transmission

Researchers at the La Jolla Institute for Allergy & Immunology have shown that cytomegalovirus (CMV) in the salivary glands can be reduced ?and in some cases eliminated ?through the use of antibodies to enhance the disease-fighting power of the immune system. The research team’s findings, based on controlled laboratory studies of mice, may also have implications for other chronic virus infec...

Cytomegalovirus exacerbates atherosclerosis through an autoimmune mechanism

. Atherosclerosis is the main cause of morbidity and mortality worldwide. Classic risk factors including smoking, diabetes, hypertension and high cholesterol levels are known to play a pivotal role in the pathogenesis of the disease that also recognises a genetic influence. However, it is well known that acute cardiovascular events may happen without the presence of the me...
