(Phys.org) --Imagine a computer so efficient that it can recycle its own waste heat to produce electricity. While such an idea may seem far-fetched today, significant progress has already been made to realize these devic...

You see only what your mind wants you to see, and this exerts a profound influence on your behaviour (full text available to subscribers)     

A team of researchers have sequenced the genome of the Pinus taeda, commonly known as the loblolly pine, and found that the tree's genetic code -- seven times larger than a human's -- is the largest and the most complete...

Measuring circulating tumor cells -- the cells that spread cancer through the body -- may be a better predictor of patient survival than the prostate-specific antigen, new research indicates.

A new study that compares cold snare polypectomy with conventional polypectomy for the removal of small colorectal polyps in anticoagulated patients. The study showed that delayed bleeding requiring hemostasis (stoppage ...

Two studies are providing new insight into germline epidermal growth factor receptor T790M mutation in familial non-small cell lung cancer. The findings suggest the need for tailored approaches for early detection and tr...

As stem cells continue their gradual transition from the lab to the clinic, a research group has discovered a new way to make large concentrations of skeletal muscle cells and muscle progenitors from human stem cells. Th...

A new system for classifying periodontal disease has been devised based on the genetic signature of affected tissue, rather than on clinical signs and symptoms. The new classification system, the first of its kind, may a...

Homeless and vulnerably housed people who have suffered a traumatic brain injury at some point in their life are more likely to visit an emergency department, be arrested or incarcerated, or be victims of physical assaul...

Salivary biomarkers have been studied to help determine the presence, risk, and progression of periodontal disease. However, clinical translation of salivary biomarkers from bench to chairside requires studies that ident...

In 2009 and 2010 two different strains of the bacterium Listeria monocytogenes were found in traditional Austrian curd cheese known as 'Quargel'. 34 people were infected, and a total of 8 patients died. Experts analyzed ...

Switches that colorectal cancer cells use to migrate away from the primary tumor site and to invade neighboring tissue have been found by researchers. This migration is the first step in metastasis, the process by which ...

Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during emb...

Pancreatic cancer is often detected at a late stage, which results in poor prognosis and limited treatment options. Researchers have now developed a method that identifies the cancer's visible precursors with 97% certain...

A standard experimental model of concussion in rats causes substantial brain damage --- but no behavioral changes comparable to those seen in patients with concussion, reports a study. The results highlight the "disconne...

The same gene family that may have helped the human brain become larger and more complex than in any other animal also is linked to the severity of autism. The gene family is made up of over 270 copies of a segment of DN...

Cancer cells -- and not normal cells -- can be killed by eliminating either the FAS receptor, also known as CD95, or its binding component, CD95 ligand, scientists have demonstrated. The discovery seems counterintuitive ...

Depression and obesity have long been associated, but how they relate over time is less clear. New research shows that adolescent females who experience one of the disorders are at a greater risk for the other as they ge...

For the first time, scientists have solved the high-resolution structure of the molecular transporter TSPO, which introduces cholesterol into mitochondria. This protein also serves as a docking site for diagnostic marker...

Preterm children are at an increased risk of having general cognitive and mathematic problems, research has concluded. "Teachers should be aware of these children's problems and need to work on ways of math instruction t...

Women who are pregnant or trying to get pregnant and taking a folic acid supplement may be at risk of reducing their folate benefit through sun exposure, a new study has warned. Folic acid is a B vitamin that is very imp...

Dust produced by New Zealand glaciers may have contributed to cooling in the Southern Ocean during the last ice age, scientists say.
