Wearable device for early detection of common diabetes-related neurological condition Posted: 28 Jul 2014 06:44 AM PDT Thanks to a small, wearable device that can hang on a pair of eyeglasses, a common complication of diabetes may get caught sooner. Researchers have developed a pupillometer that scans the patient's eyes for early signs of diabetic autonomic neuropathy -- a condition that progressively affects the autonomic nerves controlling vital organs. This kind of early detection enables early treatment, leading to far better health outcomes for the patient.

Glow in space is evidence of a hot bubble in our galaxy Posted: 28 Jul 2014 06:44 AM PDT A recent study shows that the emission is dominated by the local hot bubble of gas -- 1 million degrees -- with, at most, 40 percent of emission originating within the solar system. The findings should put to rest the disagreement about the origin of the X-ray emission and confirm the existence of the local hot bubble.

Potential 'universal' blood test for cancer discovered Posted: 28 Jul 2014 06:44 AM PDT A simple blood test that can be used to diagnose whether people have cancer or not has been devised by researchers. The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Alternatively, it could be a useful aid for investigating patients who are suspected of having a cancer that is currently hard to diagnose.

Mutations from Venus, mutations from Mars: Genetics, Men and fertility problems Posted: 28 Jul 2014 06:44 AM PDT Researchers explain why genetic fertility problems can persist in a population. Some 15% of adults suffer from fertility problems, many of these due to genetic factors. This is something of a paradox: We might expect such genes, which reduce an individual's ability to reproduce, to disappear from the population. Research may now have solved this riddle. Not only can it explain the high rates of male fertility problems, it may open new avenues in understanding the causes of genetic diseases and their treatment.

Interfering with interferon Posted: 28 Jul 2014 06:44 AM PDT Using the body's natural virus killers to prevent and treat HIV infection has been problematic until now because of the strong inflammatory response these molecules can arouse as they get rid of the invaders. Now, research has demonstrated how suppressing the activity of these molecules -- interferons -- around the time of infection could have long-term implications for the course of the disease.

Building 'invisible' materials with light Posted: 28 Jul 2014 05:07 AM PDT A new technique which uses light like a needle to thread long chains of particles could help bring sci-fi concepts such as cloaking devices one step closer to reality.

New species of mayfly discovered in India Posted: 28 Jul 2014 05:05 AM PDT Scientists have discovered a new species of mayfly in the southern Western Ghats, a mountain range along the west coast of India. The larvae have light-brown heads with light-yellow antennae, and they grow to be about 4-5 millimeters in length. Adults are also about five millimeters long, and the males and females both lack hind wings.

Hepatitis C virus genotype 1 most prevalent worldwide Posted: 28 Jul 2014 05:05 AM PDT In one of the largest prevalence studies to date, researchers from the UK provide national, regional, and global genotype prevalence estimates for the hepatitis C virus. Findings indicate that genotype 1 is the most prevalent worldwide, with over 83 million patients infected of which one-third reside in East Asia.

Dinosaurs fell victim to perfect storm of events, study shows Posted: 28 Jul 2014 05:05 AM PDT Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. They found that in the few million years before a 10km-wide asteroid struck what is now Mexico, Earth was experiencing environmental upheaval. This included extensive volcanic activity, changing sea levels and varying temperatures. At this time, the dinosaurs' food chain was weakened by a lack of diversity among the large plant-eating dinosaurs on which others preyed.

New oral drug regimens cure hardest-to-treat hepatitis C infected patients, could improve treatment uptake Posted: 28 Jul 2014 05:04 AM PDT Two new pill-only antiviral drug regimens could provide shorter, more effective treatment options with fewer side effects for the majority of patients infected with hepatitis C, even those most difficult to treat, according to the results of two studies. Around 150 million people worldwide have chronic hepatitis C virus (HCV) infection, a condition that is a major cause of liver cirrhosis and liver cancer. In the USA, numbers of people with HCV-related liver failure and liver cancer are expected to treble by 2030 because of low treatment rates.

Lifestyle choices may affect long-term heart health of childhood cancer survivors Posted: 28 Jul 2014 05:04 AM PDT Following a healthy lifestyle may lower childhood cancer survivors' risk of developing the metabolic syndrome, a study shows. The findings indicate that children with cancer and adults who had cancer when they were children should receive information about how their lifestyle may influence their long-term health.
