| First diagnostic test for Alzheimer's and Parkinson's disease on the horizon |
| A new blood test that can give an early diagnosis of neurodegenerative disease and distinguish between Parkinson’s and Alzheimer’s disease could be launched this summer, reports Marina Murphy in SCI’s Chemistry & Industry magazine. |

| APPETITE MAY BE HARD-WIRED |
| For those who struggle to lose weight, the problem might lie in their brains, not their stomachs. Researchers have found that our natural appetite could be built into our brains just after birth, and may then be set for the rest of our lives. |

| A NEW HYPOTHESIS ABOUT ALZHEIMER'S DISEASE |
| A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. |

| EYE MOVEMENT STUDIES TO HELP DIAGNOSE MENTAL ILLNESS |
| Researchers at the University of Illinois at Chicago are studying subtle abnormalities in eye movements that may one day be used to diagnose psychiatric disease. |

| SARS: LESSONS FROM THE ANIMAL KINGDOM |
| The SARS virus probably originated in animals and may have lost the ability to infect its original host - increasing the possibility it can be eliminated in humans, says a U.S. virus expert. But an animal origin also has implications for the spread of the disease. |
|
| BLOOD TEST FOR LUNG CANCER MAY BE POSSIBLE |
| A blood test that can detect one of the forms of lung cancer before it takes hold may become possible following new Russian research. |
|
| TIME FOR NEEDLE-FREE DIABETES MANAGEMENT |
| Diabetics are one step closer to blood-free glucose testing, with new developments to a wrist device that can 'suck' fluid through the skin presented to a British conference this week.
Professor Richard Guy and colleagues, from the University of Geneva in Switzerland, announced a new calibration method for the device, called 'GlucoWatch'. |
|
| NEW MEDICAL SYSTEM FOR COLON CANCER SCREENING |
| With funding from the Office of Naval Research (ONR) and other agencies, Professor Arie Kaufman, Chair and Leading Professor at the State University of New York (SUNY) Stony Brook Computer Science Department, has developed an innovative procedure called Virtual Colonoscopy. It is an accurate, cost-effective, fast, non-invasive, patient-comfortable procedure for screening of colon polyps, the precursor of cancer. In contrast, conventional colonoscopy is invasive with a risk of puncturing the colon and requires that the patient be sedated. |

| SENSOR, MOLECULAR DEVICE DEVELOPMENT FOCUS OF NSF FUNDED RESEARCH |
| Two Virginia Tech research projects -- to develop new sensors for detecting pathogens and DNA, and to improve molecular devices in electronic applications -- received Nanoscale Exploratory Research (NER) grants from the National Science Foundation (NSF). |
|
| RESEARCHERS DISTINGUISH NEW TYPE OF LEUKEMIA |
| Researchers who have studied the activity of thousands of genes in a drug-resistant form of childhood leukemia are now proposing that the disease be called mixed-lineage leukemia (MLL) because it is a distinct disease, and not a subtype of the more prevalent acute lymphoblastic leukemia (ALL). |

| GROWING WIRES IN WATER |
| US researchers have discovered a new way to grow microscopic electrical wires in water, and soon hope to be plugging into living cells. |
|
| BLOOD TEST FOR ALL CANCERS |
| A simple blood test which may allow the early detection of all forms of cancer has been developed by an Australian research team.
Similar to a cholesterol test, the 'C-Test' will be evaluated in a clinical trial in New South Wales, Victoria and the Australian Capital Territory over the next 12 months. It is based on scientific work by the John Curtin School of Medical Research at the Australian National University. |

| IIT DEVELOPS TECHNOLOGY THAT MAY HELP DOCTORS IDENTIFY BLOOD PATHOGENS FASTER |
| Students at Illinois Institute of Technology have developed a unique sensing technology that will allow doctors to detect and identify pathogens in the blood much faster than conventional lab tests can. The sensing device, known as an electronic nose, is an array of small sensors that can detect gases given off by microscopic organisms including bacteria that can infect the blood such as e. coli and staphylococcus bacteria. The sensors are linked to a computer that can analyze the gas signature and compare it to signatures from known pathogens. |

| KINSEY STUDY FINDS ADVERSE SEXUAL, EMOTIONAL SIDE EFFECTS OF BIRTH CONTROL PILLS RELATED TO DISCONTINUATION |
| The birth control pill can have significant adverse effects on sexuality and mood in some women, increasing the likelihood of early discontinuation, according to a study by the Kinsey Institute for Research in Sex, Gender and Reproduction at Indiana University. Results of the study will be reported in the July issue of the journal Contraception. |
