| Protein links liver cancer with obesity, alcoholism, hepatitis Posted: 19 Dec 2013 04:59 PM PST A new study identifies an unexpected molecular link between liver cancer, cellular stress, and risk factors for developing this cancer – obesity, alcoholism, and viral hepatitis.  |
| Renegades of cell biology: Why K-Ras gene mutations prove so deadly in cancer Posted: 19 Dec 2013 09:59 AM PST Cells with a mutation in the gene called K-Ras —- found in close to 30 percent of all cancers, but mostly those with worst prognosis, such as pancreatic cancer, colon cancer, and lung cancer -— subvert the normal mechanisms of cell death.  |
| Modern caterpillars feed at higher temperatures in response to climate change Posted: 19 Dec 2013 06:35 AM PST Caterpillars of two species of butterflies in Colorado and California have evolved to feed rapidly at higher and at a broader range of temperatures in the past 40 years, suggesting that they are evolving quickly to cope with a hotter, more variable climate.  |
| Norway's quest to discover all of its native species Posted: 19 Dec 2013 05:27 AM PST More than a thousand new species –- nearly one-quarter of which are new to science -– have been discovered in Norway since a unique effort to find and name all of the country's species began in 2009.  |
