Smokers have a 41% higher risk of suffering depression
The risk of suffering depression increases 41% in smokers, in comparison with non-smokers. This was the conclusion of a study undertaken with 8,556 participants by scientists of the University of Navarra, in collaboration with the University of Las Palmas de Gran Canaria and the Harvard School of Public Health (USA), and which demonstrates in a pioneering way the direct relationship between tobacco use and this disease.

Better regional monitoring of CO2 needed as global levels continue rising
Monitoring Earth's rising greenhouse gas levels will require a global data collection network 10 times larger than the one currently in place in order to quantify regional progress in emission reductions, according to a new research commentary by University of Colorado and NOAA researchers appearing in the April 25 issue of Science.

New lymphoma therapies targets diverse and difficult cancer
The fifth leading cause of cancer in the United States, lymphoma is made up of more than 40 rare and highly diverse diseases that target the body's lymphatic system. Lymphomas include both one of the fastest growing cancers -- Burkitt's lymphoma, which can double in size in as little as a day -- and one of the slowest, chronic lymphocytic leukemia (CLL).

Study shows positive findings in treating patients with advanced hepatitis C
The hepatitis C therapy peginterferon alfa-2b, when given as low-dose maintenance therapy, can prevent disease progression in certain patients who failed previous interferon-based hepatitis C therapies and have advanced liver disease, according to findings from a large, four-year study presented today at the 43rd annual meeting of the European Association for the Study of the Liver (EASL).

Desalination can boost US water supplies, but environmental research needed
Recent advances in technology have made removing salt from seawater and groundwater a realistic option for increasing water supplies in some parts of the U.S., and desalination will likely have a niche in meeting the nation's future water needs, says a new report from the National Research Council.

Cancer immunotherapy shows long-term promise in lung cancer
New, long-term results from a clinical trial presented today at the 1st European Lung Cancer Conference jointly organized by the European Society for Medical Oncology (ESMO) and the International Association of the Study of Lung Cancer (IASLC) show that MAGE-A3 ASCI (Antigen-Specific Cancer Immunotherapeutic), an immune-boosting treatment for lung cancer patients, reduces the risk of relapse after surgery -- to the same extent as chemotherapy but without the side-effects of chemotherapy.

Study breaks ground in revealing how neurons generate movement
When the eye tracks a bird's flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists.
