Patients With Diabetes Need Better Advice About Home Glucose Monitoring

A new study calls for better advice about home blood glucose monitoring for patients with non-insulin dependent (type 2) diabetes. Some experts believe that daily self monitoring helps to control blood glucose levels and it is often recommended. But others believe that self monitoring is complex and inconvenient and can lead to feelings of frustration and guilt. As such, there is still no firm...

Discovery May Pave The Way For A New Class Of Diabetes Drugs

Scientists have determined the structure of a protein found in cells that shows potential as a target for the development of new drugs to treat diabetes. They described the structure of a protein—MitoNEET—that was previously identified as a site where diabetes drugs could operate. The discovery of the protein’s three-dimensional structure makes it possible to design small...

Income Inequality Associated With Overnourishment And Undernourishment In India

Researchers have examined the extent to which income inequality is predictive of the double nutritional burden of under-nutrition and over-nutrition in India. They found that people living in Indian states with high levels of income inequality experienced a greater risk of both under- and over-nutrition, even after adjusting for various demographic, economic and behavioral variables.

One Type Of Antioxidant May Not Be As Safe As Once Thought

According to new research an antioxidant commonly used in nutritional and body-building supplements can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen. This leads to pulmonary arterial hypertension, a serious condition characterized by high blood pressure in the arteries that carry blood to the lungs.


Exercise And Yoga Improves Quality Of Life In Women With Early-stage Breast Cancer

Two studies report that exercise and yoga can help maintain and in some cases improve quality of life in women with early-stage breast cancer. The first study found that resistance and aerobic exercise improved physical fitness, self-esteem and body composition, and that resistance exercise improved chemotherapy completion rates. The second study demonstrated that yoga was particularly beneficial...

First Ever 'Zero Emission' Antarctic Station

The first ever "zero emission" Antarctic research station, the Princess Elisabeth Station, was recently unveiled in Brussels, Belgium. Using specialized building design and materials, a passive heating system, an energy control system, energy efficient appliances, and sound insulation techniques, engineers from the International Polar Foundation and its technical partners have managed to take a...

Pillar Of Invisibility

While we are a long way off from the lightweight, high-performance, magical cloak of Harry Potter, Muggle physicists have been busy designing ways to make invisibility possible. A recent theoretical analysis of a column-shaped invisibility cloak, by a collaboration of researchers from Sweden and China, showed that a cloak made to ideal specifications could render an object (or wizard) hidden...

'Lucky Camera' Takes Sharpest Ever Images Of Stars

Astronomers from the California Institute of Technology and the University of Cambridge have developed a new camera that produces much more detailed pictures of stars and nebulae than even the Hubble Space Telescope, and it does all this from here on Earth. Until now, images from ground-based telescopes have been invariably blurred by Earth's atmosphere. Astronomers have developed a technique,...

Hurricane Forecast: Heightened Activity For Rest Of Season

Above-average hurricane activity is expected for the remaining three months of the hurricane season, the Colorado State University forecast team said September 4. The individual month of September and the two-month period of October-November are expected to experience five named storms each. In September, the forecast calls for four of the five storms to become hurricanes and two to become major...

Treating Depression May Improve Recovery Of Heart Rate Variability Following Coronary Syndromes

Patients with depression appear to have an impaired ability to recover their heart rate variability following acute coronary syndromes such as heart attack, a factor that could increase their risk of coronary death, according to a new report. However, patients who are treated with antidepressants or whose mood lifts may experience more of an improvement in heart rate variability than those who are...

COPD Not Just A Disease Of The Lungs

Chronic Obstructive Pulmonary Disease (COPD) can no longer be judged as only a disease of the lungs, say authors of an article in The Lancet. Researchers propose to add the term chronic systemic inflammatory syndrome to the diagnosis of COPD to reflect the frequent complex chronic comorbidities. The most common comorbidities associated with COPD are skeletal muscle abnormalities, high blood...

LCD Televisions May Soon Look Outdated: Field Emission Displays Promising

Although relatively new to the market, liquid crystal display (LCD) televisions soon may be obsolete, thanks to a new technique that allows nanotech devices to be mass-produced. It could move the television industry away from the LCD display to the superior field emission display (FED). FEDs use a large array of carbon nanotubes – the most efficient emitters known – to create a higher...

'Take The Stairs' Signs Work

What would it take to get you to use the stairs instead of the escalator at your local mall? A team of researchers has found that healthy messages printed on stair risers attract climbers and might even encourage them to descend the stairs later. The riser messages "Take the Stairs" and "7 Minutes of Stair Climbing Daily Protects Your Heart" increased climbing on the staircase by 190 percent and...

Overweight Toddlers And Those Not In Day Care At Risk For Iron Deficiency

Overweight toddlers and those not enrolled in day care are at high risk for iron deficiency, according to a new study. Based on data from a national survey of 1,641 toddlers, the study found that 20 percent of overweight toddlers were iron-deficient, compared to 8 percent of those at risk for being overweight, and 7 percent of normal-weight toddlers.

Parents' Perceptions Can Hamper Kids' Asthma Care, Study Finds

Researchers have new insight into why only half of all prescribed preventive asthma medications are actually taken daily as directed and so many kids needlessly suffer symptoms. Turns out, parents' beliefs about their children's medicines (fear of side effects or dependency, even doubt that the medicines are necessary) influence how consistently they administered the drugs.

Performance-based Pay For Teachers?

Teacher performance pay is a frequently discussed and controversial topic among kindergarten through 12th-grade educators. Recent findings by economics professors suggest that states and school districts in the United States begin developing programs that examine the effects of linking teacher pay to student achievement.

Pill Box Organizers Increase HIV Patients' Adherence And Improve Viral Suppression

Inexpensive pill box organizers are an easy, successful, and cost-effective tool to help patients take their medications as prescribed, according to a new study of low-income urban residents living with HIV infection. Incomplete adherence to HIV therapy is the most common cause of incomplete viral suppression, drug resistance, disease progression, and death among people living with HIV/AIDS.

'Lego-block' Galaxies Discovered In Early Universe

The NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a 100 to 1,000 times smaller than our Milky Way Galaxy.

Dinosaur To Birds: Height Or Flight?

Paleontologists have long theorized that miniaturization was one of the last stages in the long series of changes required in order for dinosaurs to make the evolutionary "leap" to take flight and so become what we call birds. New evidence from a tiny Mongolian dinosaur, however, may leave some current theories about the evolution of flight up in the air.
