Evolutionary biology research techniques predict cancer

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. more  

UC Davis study shows grape seed extract may be effective in reducing blood pressure

Grape seed extract lowered the blood pressure of patients who participated in a UC Davis study of the benefits of the supplement on people with high blood pressure. more

'Custom' nanoparticles could improve cancer diagnosis and treatment

Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles. Designed at the molecular level to attack specific types of cancer without affecting healthy cells, the nanoparticles also have the potential to reduce side effects associated with chemotherapy, the researchers say. Their study was described today at the 231st national meeting of the American Chemical Society, the world’s largest scientific society. more  

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

Researchers report they have created pigs that produce omega-3 fatty acids, which are known to improve heart function and help reduce the risks for heart disease, representing the first cloned transgenic livestock in the world that can make the beneficial compound. The research could be a boost to both farmers and health-conscious consumers seeking an alternative and safer source of omega-3 fatty acids. Currently, the only way for humans to realize the benefits of omega-3 fatty acids is by taking dietary supplements or by eating certain types of fish that may also contain high levels of mercury. more

Penn study shows smokers assume false sense of safety from ads for low nicotine Quest® cigarettes 

A study by researchers at the Transdisciplinary Tobacco Use Research Center of the University of Pennsylvania School of Medicine found that many smokers make false inferences about the safety of new low nicotine Quest® cigarettes. This research appears in the March issue of Psychology of Addictive Behaviors. more

10-year federal flu vaccination program could save more than 6,500 lives  

To increase influenza vaccinations rates among the elderly – those ages 65 and over who are at high risk for influenza-related mortality – the federal government could consider borrowing a page from the pharmaceutical companies' prescription drug advertising campaigns. more

Method for avoiding sudden death

Sudden death is a health problem with a rate of one in every thousand inhabitants per annum. The crisis appears suddenly, although the prompt application – within a period of a few minutes – of an elecrtical discharge from a defibrillator – makes the difference between life and death. Persons with a high risk of suffering sudden death have an internal automatic defibrillator (IAD) implanted. more
