Survey of the general population in France identifies knowledge gaps in the perception of lung cancer
A prospective nationwide survey on perceptions of lung cancer in the general population of France highlights a need for increased public education on the benefits of lung cancer screening, the good survival rates of early-stage disease and the improved outcomes with new therapeutic strategies, including targeted-therapies.

Targeted next-generation sequencing reveals a high number of genomic mutations in advanced malignant
Next generation sequencing in malignant pleural mesothelioma tumors shows a complex mutational setting with a high number of genetic alterations in genes involved in DNA repair, cell survival and cell proliferation pathways. Increased accumulation of mutations correlates with early progression of the tumor and decreased survival.

Weigh-in once a week or you'll gain weight
Stepping on the scale is common among dieters but how does the frequency of weigh-ins impact weight? A new study showed that the more frequently dieters weighed themselves the more weight they lost, and if participants went more than a week without weighing themselves, they gained weight.

Lens-free microscope can detect cancer at cellular level
A lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes, has been developed by researchers. The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. It may prove especially useful in remote areas and in cases where large numbers of samples need to be examined quickly.

Multiple allergic reactions traced to single protein
A single protein has been identified as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, researchers say, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.

Scientists open new frontier of vast chemical 'space': As proof-of-principle, the team makes dozens of new chemical entities
Chemists have invented a powerful method for joining complex organic molecules that is extraordinarily robust and can be used to make pharmaceuticals, fabrics, dyes, plastics and other materials previously inaccessible to chemists.

Rx drugs, 'bath salts,' fake pot and laundry pods lead millions to call poison centers
National Poison Control Center data from 2012 show that poisonings from prescription drugs are the leading cause of injury death in the United States, and that poisonings from 'bath salts,' synthetic marijuana and laundry detergent pods are emerging threats to public health.

How breast cancer cells break free to spread in body
More than 90 percent of cancer-related deaths are caused by the spread of cancer cells from their primary tumor site to other areas of the body. A new study has identified how one important gene helps cancer cells break free from the primary tumor.
