Electronic cigarettes facilitate smoking cessation, new evidence shows

Do electronic cigarettes help smokers to quit? Yes, but… Researchers found that while nicotine containing electronic cigarettes were more effective than electronic cigarettes without nicotine (placebo) in helping smokers kick the habit, the results need to be confirmed by more studies.

Combining images, genetic data proves gene loss behind aggressive ovarian cancers

Loss of a gene called PTEN triggers some cases of an aggressive form of ovarian cancer, called high-grade serous ovarian cancer, researchers have demonstrated. In a revolutionary approach, the researchers made the discovery by combining images from cancer samples with genetic data. Show More Summary

New study outlines research priorities to improve the care of women with female genital mutilation

Further evidence on how to improve the care of women living with Female Genital Mutilation (FGM) is urgently needed, suggests a new study. A new study reviews existing evidence and key knowledge gaps in the clinical care of women with FGM. Show More Summary

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 in PLOS ONE 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. read more

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

DENVER - Next generation sequencing in malignant pleural mesothelioma (MPM) 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. read more

A survey of the general population in France identifies knowledge gaps in the perception of lung cancer

DENVER - 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. read more

An Alien Water World --"Could It be Habitable?" Asks MIT Team

Nearly 2,000 planets beyond our solar system have been identified to date. Whether any of these exoplanets are hospitable to life depends on a number of criteria. Among these, scientists have thought, is a planet's obliquity the angle of its...

High fitness level reduces chance of developing hypertension

People with the highest fitness levels are less likely to develop hypertension, according to new research in the Journal of the American Heart Association. "If you're exercising and you're fit, your chances of developing hypertension are much less than someone else who has the same characteristics but isn't fit," said Mouaz H. Show More Summary

Airline pilots can be exposed to cockpit radiation similar to tanning beds

Airline pilots can be exposed to the same amount of UV-A radiation as that from a tanning bed session because airplane windshields do not completely block UV-A radiation, according to a research letter published online by JAMA Dermatology. Airplane windshields are commonly made of polycarbonate plastic or multilayer composite glass. Show More Summary

Despite risks, benzodiazepine use highest in older people

Prescription use of benzodiazepines--a widely used class of sedative and anti-anxiety medications--increases steadily with age, despite the known risks for older people, according to a comprehensive analysis of benzodiazepine prescribing in the United States. Show More Summary

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

ARGONNE, Ill. - 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 (XFEL) pulses. One important step toward ultrafast imagingShow More Summary

Spider's web weaves way to advanced networks and displays

CHESTNUT HILL, MA (Dec. 17, 2014) - The next generation of light-manipulating networks may take their lead from designs inspired by spiders and leaves, according to a new report from two Boston College physicists and colleagues at South China Normal University. read more

Health coaching paired with gym membership works best for obese people with mental illness

LEBANON, NH - A health promotion program, called In SHAPE, specifically designed for people with serious mental illness, produced more fit participants and significant weight loss than a control group where participants only received a gym membership. read more

Consumer loyalty driven by aesthetics over functionality

When designing a new car, manufacturers might try to attract consumers with more horsepower, increased fuel efficiency or a lower price point. But new research from San Francisco State University shows consumers' loyalty and passion for an automobile brand are driven more by appearance. Show More Summary

New Photos Released From Rosetta Comet Landing Mission

SAN FRANCISCO—The Rosetta mission to comet 67P/Churyumov-Gerasimenko has released more images of the comet, including the first picture snapped by the Philae lander after its first bounce. The team discussed the images today, here at the American Geophysical Union meeting. Show More Summary

'Sugar-coated' microcapsule eliminates toxic punch of experimental anti-cancer drug

Johns Hopkins researchers have developed a sugar-based molecular microcapsule that eliminates the toxicity of an anticancer agent developed a decade ago at Johns Hopkins, called 3-bromopyruvate, or 3BrPA, in studies of mice with implants of human pancreatic cancer tissue. Show More Summary

Switching to spintronics

In a development that holds promise for future magnetic memory and logic devices, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and Cornell University successfully used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature.

Genetic mutation found to cause ovarian failure

Premature ovarian failure, also known as primary ovarian insufficiency (POI), affects 1% of all women worldwide. In most cases, the exact cause of the condition, which is often associated with infertility, is difficult to determine. read more

Hump Day Hilarity – model the bouncing ball

Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit like watching a ball bouncing down a rocky hillside. You can predict some aspects of it behaviour but not others. You can predict it will…

'Perfect storm' quenching star formation around a supermassive black hole

High-energy jets powered by supermassive black holes can blast away a galaxy's star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones. read more
