Scientists have developed a rapid new blood test which may help predict the likelihood of a heart attack. The research published in Nature Medicine shows how a new science called Metabonomics can be used to test for coronary artery disease, using minimally invasive procedures. The test, which only needs a few drops of blood, measures the magnetic properties of molecules in blood using high frequency radio waves, which are then analysed using an advanced computer programme capable of detecting abnormal patterns of signals associated with heart disease.
Scientists have averted the onset of neurodegenerative disease in fruit flies by administering medication to flies genetically predisposed to a disorder akin to Parkinson’s disease. The result suggests a new approach to the treatment of human disorders including Parkinson’s and Alzheimer’s diseases. Parkinson’s disease is the second most common human neurodegenerative disorder, characterized by tremors, postural rigidity and progressive deterioration of dopaminergic neurons in specific areas of the brain. Despite the evolutionary gulf separating humans and fruit flies, neurotoxicity unfolds in a similar manner in both species.
