The increasing use of expensive medical imaging procedures in the US like positron emission tomography scans is being driven, in part, by patient decisions made after obtaining information from lay media and non-experts,...

Assessing the route to cancer on a case-by-case basis might make more sense than basing a patient's cancer treatment on commonly disrupted genes and pathways, a new study indicates. "This paper argues for the importance ...

The mental health conditions of most people who commit suicide remain undiagnosed, even though most visit a primary care provider or medical specialist in the year before they die. To help prevent suicides, health care p...

Bacteria have developed many different ways of smuggling their toxic cargo into cells. A new study has helped scientists discover how Tc toxins inject bacterial toxins. The discovery has wide-reaching potential impact, f...

A new strategy to tackle an aggressive subtype of ovarian cancer using a new nanoscale drug-delivery system designed to target specific cancer cells has been developed. A research team has devised a cluster of nanopartic...

A novel technique for detecting ALK rearrangements in non-small cell lung cancers (NSCLCs) has been developed that is more sensitive and easier to perform than currently available techniques. The technique can help enhan...

Routine testing with both fluorescent in situ hybridization and immunohistochemistry may enhance the detection of ALK-positive non-small cell lung cancer, new research suggests. Accurate determination of ALK-positive tum...

Engineered tissues like the ones used to create artificial skin need a scaffold for cells to grow on. Now a team of researchers has coaxed cells called fibroblasts into creating a scaffold that mimics the body's own inte...

Collecting and bleeding horseshoe crabs for biomedical purposes causes short-term changes in their behavior and physiology that could exacerbate the crabs' population decline in parts of the East Coast. Authors of a new ...

The millions of Americans living with more than one chronic disease are at high risk of poor health outcomes, and account for a disproportionate share of health care costs. A group of experts formed to address knowledge ...

In many cases the root of resistance to BRAF inhibitors may lie in a never-before-seen autophagy mechanism induced by the BRAF inhibitors vermurafenib and dabrafenib, new research indicates. Half of melanoma patients wit...

Cancer cells have long been known to have higher rates of the energy-generating metabolic pathway known as glycolysis. This enhanced glycolysis is thought to allow cancer cells to survive the oxygen-deficient conditions ...

In 2009, a new technology was developed that could elucidate the mystery behind cellular memory. Building on this technology, researchers have now identified 100 new molecular players that ensure cellular knowledge of ow...

A program of cognitive behavioral therapy that addresses both mood and diabetes self-care led to improved blood sugar control and produced faster relief of depression in patients with poorly-controlled type 2 diabetes. "...

Older parents frequently give help to their middle-aged offspring, and their perceptions about giving this help may affect their mental health, according to a team of researchers. The team's results suggest that parents ...

Defective blood coagulation is one of the leading causes of preventable death in patients who have suffered trauma or undergone surgery. Now, a new optical device requires only a few drops of blood and a few minutes to m...

New research shows that saturated fat builds more fat and less muscle than polyunsaturated fat. This is the first study on humans to show that the fat composition of food not only influences cholesterol levels in the blo...

"Gravity" is the Hollywood example of a real problem many space agencies are trying to deal with. Space junk, dead satellites and other debris pose a threat to current and future missions and the European Space Agency ha...
