New study of political defections identifies 'personality type' prone to switch sides Posted: 23 Sep 2012 05:32 PM PDT A new study on political defections has identified an 'archetype' for someone who is likely to break political ranks.

Some deadly breast cancers share genetic features with ovarian tumors Posted: 23 Sep 2012 11:51 AM PDT The most comprehensive analysis yet of breast cancer shows that one of the most deadly subtypes is genetically more similar to ovarian tumors than to other breast cancers. The findings suggest that most basal-like breast tumors and ovarian tumors have similar genetic origins and potentially could be treated with the same drugs.

Researchers solve puzzle of B-cell lymphoma development Posted: 23 Sep 2012 11:51 AM PDT In germinal centers, immune cells learn to fight pathogens with high specificity. Researchers have now identified subpopulations of B cells at the germinal centers which express the proto-oncogene Myc (red). They showed that Myc is essential for the formation and maintenance of germinal centers. Their findings have implications for the pathogenesis of B-cell lymphomas.

Cancer research yields unexpected new way to produce nylon Posted: 23 Sep 2012 11:51 AM PDT In their quest for a cancer cure, researchers made a serendipitous discovery -- a molecule necessary for cheaper and greener ways to produce nylon. The finding arose from an intriguing notion that some of the genetic and chemical changes in cancer tumors might be harnessed for beneficial uses.

Genomic similarities between breast cancer and ovarian cancers revealed; Findings could aid new treatments Posted: 23 Sep 2012 11:50 AM PDT One subtype of breast cancer shares many genetic features with high-grade serous ovarian cancer, a cancer that is very difficult to treat, according to researchers. The findings suggest that the two cancers are of similar molecular origin, which may facilitate the comparison of therapeutic data for subtypes of breast and ovarian cancers.

Constraining world trade is unlikely to help the climate, study finds Posted: 23 Sep 2012 11:50 AM PDT From rubber dinghies to television sets: the emissions of greenhouse gases in countries like China are to a significant extent caused by the production of goods that are exported to Germany or the United States. But this doesn't necessarily mean that Western countries have relocated their emission-intensive industries and hence escape regulation for climate protection, according to a new study.

Cancer genome analysis of breast cancer: Team identifies genetic causes and similarity to ovarian cancer Posted: 23 Sep 2012 11:50 AM PDT A team of scientists with The Cancer Genome Atlas program reports their genetic characterization of 800 breast tumors, including finding some of the genetic causes of the most common forms of breast cancer, providing clues for new therapeutic targets, and identifying a molecular similarity between one sub-type of breast cancer and ovarian cancer.

Severe economic loss for European forest land expected by 2100 Posted: 23 Sep 2012 11:18 AM PDT By 2100 the climate change is expected to reduce the economic value of forest land by 14 to 50 percent, which equates to a potential damage of several hundred billion Euros unless effective countermeasures are taken. This is the conclusion of the first pan-European study on the economic effects of climate change on forest land.

New chemistry technique reproduces nature's elusive complexity Posted: 23 Sep 2012 11:18 AM PDT Scientists have shown how to synthesize in the laboratory an important set of natural compounds known as terpenes. The largest class of chemicals made by living organisms, terpenes are made within cells by some of the most complex chemical reactions found in biology.

Disparities exist in surgical management of thyroid cancer Posted: 23 Sep 2012 11:12 AM PDT A spectrum of disparities exist in the surgical management of well-differentiated thyroid cancer, according to new data.

Novel sequencing tools to play important role in understanding form of papillary thyroid cancer Posted: 23 Sep 2012 11:12 AM PDT Next-generation sequencing analyses of the follicular variant of papillary thyroid carcinoma may elucidate the biological underpinnings and clinical behavior of an increasingly common disease, according to new data.

New mouse model may provide insights into rare genetic syndrome Posted: 23 Sep 2012 11:12 AM PDT ew mouse models can help scientists study a rare disease, called SECISBP2 syndrome, that causes abnormal thyroid hormone metabolism, delayed bone maturation, as well as other abnormal characteristics that vary by individual, according to new data.

Screening for specific genetic mutations with fine needle aspirations could reduce need for thyroid surgery Posted: 23 Sep 2012 11:12 AM PDT Screening air-dried fine needle aspirations (FNA) for a panel of genetic mutations linked to follicular or papillary thyroid cancer could reduce the need for diagnostic thyroid surgery, according to new data.

Researchers develop editing toolkit for customizing zebrafish genomes Posted: 23 Sep 2012 11:12 AM PDT An international team of scientists has developed a highly-efficient means of editing zebrafish genomes for research purposes, eliminating a bottleneck that has stymied biomedical scientists from using the fish as a model for human disease.

Stratosphere targets deep sea to shape climate: North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss Posted: 23 Sep 2012 11:12 AM PDT A new study suggests something amazing: Periodic changes in winds high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate.
