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

Wed, 17/12/2014 - 10:15pm
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

Wed, 17/12/2014 - 10:14pm
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

Wed, 17/12/2014 - 10:14pm
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

Wed, 17/12/2014 - 10:14pm
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.

Satellites measure increase of Sun's energy absorbed in the Arctic

Wed, 17/12/2014 - 8:41pm
NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 -- a trend that aligns with the steady decrease in Arctic sea ice during the same period.

Satellite sees holiday lights brighten cities

Wed, 17/12/2014 - 8:40pm
Even from space, holidays shine bright. With a new look at daily data scientists have identified how patterns in nighttime light intensity change during major holiday seasons -- Christmas and New Year's in the United States and the holy month of Ramadan in the Middle East.

Lens-free microscope can detect cancer at cellular level

Wed, 17/12/2014 - 8:40pm
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.

Surprising theorists, stars within middle-aged clusters are of similar age

Wed, 17/12/2014 - 8:40pm
An examination of middle-aged star clusters reveals an unexpectedly narrow age range among their stars, suggesting that large groups of stars evolve differently than previously understood.

Policy action urgently needed to protect Hawaii's dolphins

Wed, 17/12/2014 - 8:40pm
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

Wed, 17/12/2014 - 8:40pm
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.

Colorado River Delta greener after engineered pulse of water

Wed, 17/12/2014 - 7:11pm
The engineered spring flood that brought water to previously dry reaches of the lower Colorado River and its delta resulted in greener vegetation, the germination of new vegetation along the river and a temporary rise in the water table, according to new results from the binational team of scientists studying the water's effects.

Ancient, hydrogen-rich waters deep underground around the world: Waters could support isolated life

Wed, 17/12/2014 - 7:11pm
A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometers beneath Earth's surface in rock fractures in Canada, South Africa and Scandinavia. Common in Precambrian Shield rocks -- the oldest rocks on Earth -- the ancient waters have a chemistry similar to that found near deep sea vents, suggesting these waters can support microbes living in isolation from the surface.

Multiple allergic reactions traced to single protein

Wed, 17/12/2014 - 7:10pm
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.
