Drop In Cancer Deaths Tied Primarily To Gains In Behavior And Screening - Behavior change and improvements in screening have contributed equally and substantially to the 13 percent decline in cancer mortality rates, according to new research. Cancer treatment after diagnosis has also contributed to the decline, although this is less of a factor than behavioral changes and screening.... Why We Remember Important Things And Forget Trivia: Neuron's Synapses Remodel Themselves - Where would we be without our ability to remember important information or, for that matter, to forget irrelevant details? Thanks to the flexibility of the nerve cell's communication units, called synapses, we are good at both. Up to now, only the receiving side of a synapse was believed to play an active role in this reorganization of the brain, which is thought to underlie our ability to learn but also to forget. An incorrect assumption, as scientists can now show.... Vaccine Against Multiple Sclerosis? Mouse Experiment Yields Promising Results - Researchers in Germany have succeeded in vaccinating mice with specially treated, autologous immune cells and preventing them from developing encephalitis, which is similar to multiple sclerosis in humans....

Antioxidants Are Unlikely To Prevent Aging, Study Suggests - Diets and beauty products which claim to have anti-oxidant properties are unlikely to prevent aging, according to new research. Scientists in England say this is because a key 50-year-old theory about the causes of aging is wrong.... Genomic Signature Of Colon Cancer May Individualize Treatment - Researchers have developed a model for predicting risk of recurrence in early stage colon cancer patients, and have used the model to also predict sensitivity to chemotherapy and targeted therapy regimens.... Climate Clues In Southern Ocean: Ocean Currents Surprisingly Resistant To Intensifying Winds - The Antarctic Circumpolar Current is the current system with the largest volume transport in the world ocean. Between 40° and 60°S strong westerlies move about 140 million cubic meters of water per second around the Antarctic continent (this is about five times the transport of the Gulf Stream). Vertical motions associated with this current have been responsible for transporting a substantial fraction of the anthropogenic carbon dioxide emissions from the atmosphere to the deep ocean, thereby effectively damping the rate of global warming.... Pros And Cons Of Gastric Bypass Surgery For Severe Obesity - Severely obese patients who underwent two different gastric bypass techniques had lost up to 31 per cent of their Body Mass Index (BMI) after four years, with no deaths reported among the 50 study subjects, according to an article in the British Journal of Surgery.... Scientists And Fishermen Join Forces To Track Celtic Sea Cod - A joint project between the Irish fishing industry and scientists to track stocks of cod in the Celtic Sea is starting to yield interesting results.

The project is designed to study the growth and migration of both the inshore juvenile component and the offshore adult spawning component of the stock.... Do You Know You're Having A Stroke? - A majority of stroke patients don't think they're having a stroke -- and as a result -- delay seeking treatment until their condition worsens.... Disappearing Superconductivity Reappears -- In 2-D - Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor -- but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.... Eating Eggs When Pregnant Affects Breast Cancer In Offspring - A stunning discovery based on epigenetics (the inheritance of propensities acquired in the womb) reveals that consuming choline -- a nutrient found in eggs and other foods -- during pregnancy may significantly affect breast cancer outcomes for a mother's offspring. This finding is the first to link choline consumption during pregnancy to breast cancer. It also is the first to identify possible choline-related genetic changes that affect breast cancer survival rates. The 'genetic impact' of a pregnant woman's diet has a profound effect on her child....
