Increased risk of developing lung cancer after radiotherapy for breast cancer
Women who have radiotherapy for breast cancer have a small but significantly increased risk of subsequently developing a primary lung tumor, and now research has shown that this risk increases with the amount of radiation absorbed by the tissue.

Researchers find arid areas absorb unexpected amounts of atmospheric carbon
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere.

Scaffolding protein promotes growth and metastases of epithelial ovarian cancer
Researchers from Fox Chase Cancer Center have shown that NEDD9, a scaffolding protein responsible for regulating signaling pathways in the cell, promotes the growth and spread of epithelial ovarian cancer.

Blood test could provide rapid, accurate method of detecting solid cancers
A blood sample could one day be enough to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient's body and responses to treatment.

Self-assembled superlattices create molecular machines with 'hinges' and 'gears'
A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.

Circumcision could prevent prostate cancer... if it's performed after the age of 35
Researchers at the University of Montreal and the Institut National de la Recherche Scientifique-Institut-Armand-Frappier have shown that men circumcised after the age of 35 were 45 percent less at risk of later developing prostate cancer than uncircumcised men.

Gene sequencing project discovers mutations tied to deadly brain tumors in young children
The St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project has identified new mutations in pediatric brain tumors known as high-grade gliomas, which most often occur in the youngest patients.

Researchers find that renal cancer cells thrive when put in the right environment and supported by a specific enzyme
Tumor cells are picky about where they live. In the wrong environment, they fail to reach their potential.

Friedreich's ataxia -- an effective gene therapy in an animal model
The team led by Helene Puccio, director of research for Inserm at the Institute of Genetics and Molecular and Cellular Biology in close collaboration with Patrick Aubourg's team has demonstrated, in the mice, the efficacy of gene therapy for treating the heart disease associated with Friedreich's ataxia, a rare hereditary neurodegenerative disorder.

Six months hormone therapy in addition to radiotherapy improves prostate cancer survival
Men with prostate cancer that is small and confined to the prostate gland but that is at risk of growing and spreading, do better if they are treated with radiotherapy combined with androgen deprivation therapy, which lowers their levels of the male hormone, testosterone, according to new research to be presented at the 33rd conference of the European Society for Radiotherapy and Oncology in Vienna.

Smoking visibility mapped for the first time
The visibility of smoking in city streets has for the first time anywhere been mapped, in new research from the University of Otago, Wellington, New Zealand.

Groundbreaking optical device could enhance optical information processing, computers
At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface.

Non-invasive imaging instead of repeated biopsy in active monitoring of prostate cancer
A University of Colorado Cancer Center study being presented today at the American Association for Cancer Research Annual Meeting 2014 describes a novel method to 'manipulate the lipid metabolism in the cancer cell to trick them to use more radiolabeled glucose, the basis of PET scanning.'

Sweden has 2-3 times as many adolescents and young adults with type 1 diabetes as previously thought; Findings have potential implications for other high-income countries
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that Sweden -- the country already thought to have the second highest prevalence of type 1 diabetes in the world -- could have 2-3 times more adolescents and young adults with type 1 diabetes than previously estimated.

Scripps Research Institute scientists provide new grasp of soft touch
A study led by scientists at the Scripps Research Institute has helped solve a long-standing mystery about the sense of touch.

Scientists find potential drug targets in deadly pediatric brain tumors
Researchers studying a rare, always fatal brain tumor in children have found several molecular alterations that drive the cancer, according to a new study from scientists at Dana-Farber/Boston Children's Cancer and Blood Disorders Center and McGill University.

Columbia scientists identify key cells in touch sensation
In a study published in the April 6 online edition of the journal Nature, a team of Columbia University Medical Center researchers led by Ellen Lumpkin, Ph.D., associate professor of somatosensory biology, solve an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures.

Field study shows why food quality will suffer with rising CO2
Climate change is hitting home -- in the pantry, this time.

Amino acid fingerprints revealed in new study
Stuart Lindsay and his colleagues at Arizona State University's Biodesign Institute have taken a major step toward the sequencing of proteins, demonstrating the accurate identification of amino acids, by briefly pinning each in a narrow junction between a pair of flanking electrodes and measuring a characteristic chain of current spikes passing through successive amino acid molecules.

One in 3 intensive care survivors develop depression that manifests as physical symptoms
A third of intensive care patients develop depression that typically manifests as physical, or somatic, symptoms such as weakness, appetite change, and fatigue, rather than psychological symptoms, according to one of the largest studies to investigate the mental health and functional outcomes of survivors of critical care, published in The Lancet Respiratory Medicine. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
