Scientists Break the Genetic Code for Diabetes in Greenland
New Danish genetics research explains the high incidence of type 2 diabetes in the Greenlandic population. The ground-breaking findings have just been published in the prestigious scientific journal Nature. A spectacular piece of detective work has mapped a special gene variant among Greenlanders which plays a particularly important role in the development of type 2 diabetes.

'Virtual Human' Shows that Stiff Arteries can Explain the Cause of High Blood Pressure
High blood pressure is highly age-related and affects more than 1 billion people worldwide. But doctors can't fully explain the cause of 90 per cent of all cases. A computer model of a "virtual human" suggests that stiff arteries alone are enough to cause high blood pressure.

New Sensor could Light the Way Forward in Low-Cost Medical Imaging
New research published in Nature's Scientific Reports, identifies a new type of light sensor that could allow medical and security imaging, via low cost cameras. The team of researchers from the University of Surrey have developed a new 'multispectral' light sensor that detects the full spectrum of light, from ultra-violet (UV), to visible and near infrared light.

Appeal of Well-Being Applications Often Short-Lived
According to a doctoral thesis by Research Scientist Kirsikka Kaipainen from VTT Technical Research Centre of Finland, online and mobile applications for stress management and healthy eating reach a large number of users but their appeal tends to be short-lived. Applications can contribute to improved well-being and provide support for behavioural changes as long as they are simple, attractive and easy to integrate into everyday life.

Mobile Phone Data Helps Combat Malaria
An international study led by the University of Southampton and the National Vector-borne Diseases Control Programme (NVDCP) in Namibia has used mobile phone data to help combat malaria more effectively. The study used anonymised mobile records to measure population movements within Namibia in Africa over the period of a year (2010-11).

Phase Contrast Improves Mammography
Phase contrast X-ray imaging has enabled researchers at ETH Zurich, the Paul Scherrer Institute (PSI) and the Kantonsspital Baden to perform mammographic imaging that allows greater precision in the assessment of breast cancer and its precursors. The technique could improve biopsy diagnostics and follow-up.

Electronic Nose Sniffs Out Prostate Cancer Using Urine Samples
We may soon be able to make easy and early diagnoses of prostate cancer by smell. Investigators in Finland have established that a novel noninvasive technique can detect prostate cancer using an electronic nose. In a proof of principle study, the eNose successfully discriminated between prostate cancer and benign prostatic hyperplasia (BPH) by "sniffing" urine headspace (the space directly above the urine sample). Results using the eNose are comparable to testing prostate specific antigen (PSA), reports the Journal of Urology®.
