Routine Use Of MRI Scans To Evaluate Breast Cancer ChallengedA new study suggests women with newly-diagnosed breast cancer who receive an MRI after their diagnosis face delays in starting treatment and are more likely to receive a mastectomy. The study also shows that despite lack of evidence of their benefit, the routine use of MRI scans in women newly diagnosed increased significantly between 2004 and 2005, and again in 2006.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 3:00 pm Valley Networks On Mars Formed During Long Period Of Episodic FloodingAncient features on the surface of Mars called valley networks may well have been carved by recurrent floods during a long period when the martian climate may have been much like that of some arid or semiarid regions on Earth. An alternative theory that the valleys were carved by catastrophic flooding over a relatively short time is not supported by the new results.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 3:00 pm Fluctuations In Serotonin Transport May Explain Winter BluesIn the first study of its kind in the living human brain, scientists have discovered greater levels of serotonin transporter in the brain in winter than in summer. These findings have important implications for understanding seasonal mood change in healthy people, vulnerability to seasonal affective disorders and the relationship of light exposure to mood.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 3:00 pm Urbanization Reconfigures Surface HydrologyWhat are the consequences of human-made tinkering with land cover and hydrology on surrounding native desert ecosystems and biodiversity? This question forms the backdrop for a case study published in the journal BioScience, which found that one of the most profound impacts of urbanization is the "reconfiguration of surface hydrology."Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 3:00 pm Putting The Squeeze On Nitrogen For High Energy MaterialsResearchers from the Carnegie Institution's Geophysical Laboratory report changes in the melting temperature of solid nitrogen at pressures up to 120 gigapascals and temperatures reaching 2,500° Kelvin. These results, plus observed changes in the structure of solid nitrogen at high pressures, could lead to new high energy nitrogen- or hydrogen-based fuels in the future. Hypothesized nitrogen polymers could form materials with higher energy content than any known non-nuclear material.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 3:00 pm Gene Therapy For Blindness Improves Vision, Safety Study IndicatesNo significant adverse effects were reported during a safety trial testing gene therapy on three patients with a type of hereditary blindness called Leber congenital amaurosis type 2.

However, after birth, their brain grew more quickly than it does for Homo sapiens and became larger too. Nevertheless, the individual lifespan ran just as slowly as it does for modern human beings.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 12:00 pm New Once-a-week Treatment For Type 2 Diabetes DevelopedResearchers have reported that a new once-weekly treatment for type 2 diabetes could replace the more common twice-daily injection.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 12:00 pm Early Phase Breast Cancer Study Suggests New Approach Can Re-sensitize TumorsWomen with hormone-receptor positive, metastatic breast cancer may take medications for years to help keep their cancer at bay, but when the tumor becomes resistant to anti-hormonal drugs, treatment with chemotherapy becomes the only option. But a new study may change this approach. Early data suggests a new treatment approach can "re-sensitize" the tumor, allowing anti-hormonal drugs to do their job once again.Source: ScienceDaily: Latest Science News | 9 Sep 2008 | 12:00 pm Early Warning System For Cardiac Patients For Home UseHeart disease is the number one cause of death in Europe and early diagnosis is essential to save lives.
