Prognostic factors identified for peripheral squamous cell carcinomas of the lung
A better survival outcome is associated with low blood levels of squamous cell carcinoma antigen, or absence of tumor invasion either into the space between the lungs and chest wall or into blood vessels of individuals with a peripheral squamous cell carcinoma, a type of non-small cell lung cancer.

Climate change caused by ocean, not just atmosphere, new Rutgers study finds
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. Read about a Rutgers study published in Science that reveals another equally important factor in regulating the earth's climate.

NASA identifies ice cloud above cruising altitude on Titan
NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles.

Some like it loud
Species of poison frogs that utilize bright warning coloration as protection from predators are more likely to develop louder, more complex calls than relatives that rely on camouflage. New research indicates that because these visual cues establish certain species as unsavory prey, they are free to make noisy calls in plain sight and better attract possible mates.

Law of the Sea authorizes animal tagging research without nations' consent
Scientists who study migratory marine animals can rarely predict where the animals' paths will lead. In a new paper, Duke researchers argue that coastal nations don't have precedent under the law of the sea to require scientists to seek advance permission to remotely track tagged animals who may enter their waters. Requiring advance consent undermines the goals of the law, which is meant to encourage scientific research for conservation of marine animals.

New study finds options for climate change policy are well characterized
Policy options for climate change risk management are straightforward and have well understood strengths and weaknesses, according to a new study by the American Meteorological Society Policy Program.

New hope for drug discovery in African sleeping sickness
The neglected tropical disease affects tens of thousands of people and is mostly fatal. Now, new research co-​​authored by Northeastern chemistry professor Michael Pollastri has identified hundreds of chemical compounds that could lead to a cure.

Clues to genetics of congenital heart defects emerge from Down syndrome study
The largest genetic study of congenital heart defects in individuals with Down syndrome found a connection to rare, large genetic deletions affecting cilia.

New findings will improve the sex lives of women with back problems
Newly published findings from the University of Waterloo are giving women with bad backs renewed hope for better sex lives. The findings -- part of the first-ever study to document how the spine moves during sex -- outline which sex positions are best for women suffering from different types of low-back pain. The new recommendations follow on the heels of comparable guidelines for men released last month.

New compounds reduce debilitating inflammation
Six Case Western Reserve scientists are part of an international team that has discovered two compounds that show promise in decreasing inflammation associated with diseases such as ulcerative colitis, arthritis and multiple sclerosis. The compounds, dubbed OD36 and OD38, appear to curtail inflammation-triggering signals from RIPK2. RIPK2 is an enzyme that activates high-energy molecules to prompt the immune system to respond with inflammation. The findings of this research appear in the Journal of Biological Chemistry.
