Where unconscious memories form (December 17, 2010) -- A small area deep in the brain called the perirhinal cortex is critical for forming unconscious conceptual memories, researchers have found. ... > full story

Novel drug offers hope for early intervention in cystic fibrosis patients (December 17, 2010) -- Cystic fibrosis (CF) patients with normal to mildly impaired lung function may benefit from a new investigational drug designed to help prevent formation of the sticky mucus that is a hallmark of the disease, according to researchers involved in a phase 3 clinical trial of the drug. Called denufosol, the investigational medication can be given early in the CF disease process, and may help delay the progression of lung disease in these patients, the researchers found. ... > full story

Total lunar eclipse and winter solstice coincide on Dec. 21 (December 17, 2010) -- With frigid temperatures already blanketing much of the United States, the arrival of the winter solstice on Dec. 21 may not be an occasion many people feel like celebrating. But a dazzling total lunar eclipse to start the day might just raise a few chilled spirits. ... > full story

Ion channel responsible for pain identified (December 17, 2010) -- Neuroscience researchers conducting basic research on ion channels have demonstrated a process that could have a profound therapeutic impact on pain. ... > full story

Small islands in the Pacific: Duel between freshwater and sea water (December 17, 2010) -- It is said that the first refugees of climate change will come from the Pacific. In the midst of this ocean’s tropical regions are scattered 50,000 small islands, 8,000 of them inhabited. They are particularly vulnerable to the impacts of global warming. These effects include rising sea-water levels, drought and diminishing stocks of freshwater. ... > full story

Asthma disproportionately affects low-income populations (December 17, 2010) -- Almost 5 million Californians have been diagnosed with asthma, and those living in poverty suffer more severe consequences than those in higher income brackets, according to a new report. Low-income Californians with asthma experience more frequent symptoms, end up in the emergency room or hospital more often, and miss more days of work and school. The study calculates prevalence among adults and children in California counties. ... > full story

Mom's voice plays special role in activating newborn's brain (December 17, 2010) -- A mother's voice will preferentially activate the parts of the brain responsible for language learning, say researchers. The research team made the discovery after performing electrical recordings on the infants within the 24 hours following their birth. ... > full story

Gene information predicts survival time, possible new treatment options for lung-cancer patients (December 17, 2010) -- Researchers have discovered sets of genes active in cancer cells and normal tissue that predict survival time and potential new treatments for patients with non-small cell lung cancer. ... > full story

More than 100 new species described by California Academy of Sciences in 2010 (December 17, 2010) -- In an effort to address the critical need for data about the diversity of life on Earth, scientists from the California Academy of Sciences have spent the past year exploring some of the planet's most diverse habitats, searching for new species and creating comprehensive biodiversity maps. In 2010, they have added 113 new relatives to our family tree: 83 arthropods, 20 fishes, four corals, two sea slugs, two plants, one reptile, and one fossil mammal. ... > full story

Decades after childhood radiation, thyroid cancer a concern (December 17, 2010) -- When children are exposed to head and neck radiation, whether due to cancer treatment or multiple diagnostic CT scans, the result is an increased risk of thyroid cancer for the next 58 years or longer, according to new research. ... > full story

The birth of time: Quantum loops describe the evolution of the Universe (December 17, 2010) -- What was the Big Bang and what happened before it? Scientists have attempted to answer the question. Within the framework of loop quantum gravity they have put forward a new theoretical model, which might prove useful for validating hypotheses about events prior to the Big Bang. This achievement is one of the few models describing the full Einstein's theory and not merely its greatly simplified version. ... > full story
