Targeted next-generation sequencing reveals a high number of genomic mutations in advanced malignant

Science News Daily - December 17, 2014 - 5:15pm
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

Science News Daily - December 17, 2014 - 5:14pm
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.

Consumer loyalty driven by aesthetics over functionality

Science News Daily - December 17, 2014 - 5:14pm
Consumers' loyalty and passion for an automobile brand are driven more by appearance than practical concerns. Aesthetics that resonate on an emotional level are more responsible for brand loyalty than such factors as functionality and price, the study found.

Ultrafast imaging of complex systems in 3-D at near atomic resolution nears

Science News Daily - December 17, 2014 - 5:14pm
It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser pulses. One important step toward ultrafast imaging of samples with a single X-ray shot is understanding the interaction of extremely brilliant and intense X-ray pulses with the sample, including ionization rates.

Lens-free microscope can detect cancer at cellular level

Science News Daily - December 17, 2014 - 3:40pm
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.

Policy action urgently needed to protect Hawaii's dolphins

Science News Daily - December 17, 2014 - 3:40pm
Tourism is increasing pressure on Hawaii's spinner dolphins. A new study shows that long-proposed federal regulations to limit daytime access to bays where the dolphins rest are greatly needed, but local, community-based conservation measures tailored to each individual bay will speed their acceptance. A one-size-fits-all approach will not work, authors say.

New conversion process turns biomass 'waste' into lucrative chemical products

Science News Daily - December 17, 2014 - 3:40pm
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.
