A novel heart failure symptom in advanced heart failure patients has been identified by cardiologists: shortness of breath while bending over, such as when putting on shoes. The condition, which cardiologists named "bend...

Engineering researchers have developed a new, stretchable antenna that can be incorporated into wearable technologies, such as health monitoring devices. The researchers wanted to develop an antenna that could be stretch...

Sifting flu-related tweets can help track the illness at the local level, not just on a national scale, researchers have found. The finding is important because key decisions on how to prepare for and treat a flurry of f...

A new and innovative computing machine is currently attracting a great deal of attention in specialist circles. A team under the leadership of Matthias Troyer, a professor at ETH Zurich, has now confirmed that the machin...

Body temperature is elevated endogenously in relapsing-remitting multiple sclerosis and linked to worse fatigue, researchers have demonstrated for the first time. "We found that body temperature was elevated among patien...

Using genomic analysis to study cancer in dogs can help develop new therapies for humans with cancer, according to a proof-of-concept study underway. Pure-breed dogs, whose genetics have been standardized by hundreds of ...

The health benefits of eating dark chocolate have been extolled for centuries, but the exact reason has remained a mystery -- until now. Researchers reported that certain bacteria in the stomach gobble the chocolate and ...

When a heart gets damaged, such as during a major heart attack, there's no easy fix. But scientists working on a way to repair the vital organ have now engineered tissue that closely mimics natural heart muscle that beat...

In 2012, researchers determined a considerable added benefit for ipilimumab in pretreated patients. However, there were no suitable data for non-pretreated patients. Since the treatment effects presented by the manufactu...

Duke engineers have devised a way to improve the efficiency of lithotripsy--the demolition of kidney stones using focused shock waves. After decades of research, all it took was cutting a groove near the perimeter of the...

Demand for MRI is growing to help diagnose certain diseases and conditions, but due to the strong magnetic forces they usually aren't recommended for patients with implanted cardiac devices. Researchers are now investiga...

Infrared motion-capture technology used in video games is making its way to hospital rooms, where researchers hope to learn new ways to prevent falls among hospital patients. The device looks like a thin black box. The s...

Surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter have been discovered by a team of researchers. These ultra-tiny but ultra-bright nanoprobes should be a ...

Engineers have reversed a decades-long trend of decreasing efficiency in lithotripsy machines by designing simple modifications to shock wave lenses. The incidence of kidney stones in the United States has more than doub...

Youngsters exposed to methamphetamine before birth had increased cognitive problems at age 7.5 years, highlighting the need for early intervention to improve academic outcomes and reduce the potential for negative behavi...

Lingering stress from major disasters can damage health years later, according to a new study that found a three-fold spike in heart attacks continued in New Orleans six years after Hurricane Katrina. Researchers also fo...

As some countries and companies roll out new rules to limit animal testing in pharmaceutical products designed for people, scientists are stepping in with a new way to test therapeutic drug candidates and determine drug ...

A bacterial infection can throw off the equilibrium between two key proteins in the lungs and put patients at risk for a highly lethal acute lung injury, researchers report. Bacteria can alter a single amino acid in the ...

Archaeologists have found the oldest complete example in the world of a human with metastatic cancer in a 3,000 year-old skeleton. The skeleton of the young adult male was found in a tomb in modern Sudan in 2013 and date...

A shot of Jose Cuervo probably isn't what first comes to mind when considering ways to combat obesity and type 2 diabetes. But new research finds that a certain sugar found in tequila could lower blood glucose levels in ...
