More nutritious, less toxic

Research led by Dartmouth scientists found that zooplankton fed high-quality, phosphorous-rich food end up with much lower concentrations of toxic methylmercury. The better-fed animals gained more weight relative to the amount of toxin they ingested, thus diluting the level of toxin in their tissues. The result suggests ways in which methylmercury and other toxins can be slowed in their passage up the aquatic food chain to fish and humans.

4. New chemistry approach promises less expensive drugs
   03-29-2007 · EurekAlert!
   With a newly discovered method of assembling organic molecules, chemists may have found a way to sidestep many of the expensive and hazardous barriers that stand in the way of drug development. The new approach allows scientists to synthesize molecules without employing toxic catalysts, and it also does not generate alternate versions of drug molecules that can damage the body, two perennial issues that plague the manufacturing process.

6. Study takes first look at toxic air pollution in urban parking garages, finds SUVs bigger polluters
   08-23-2007 · EurekAlert!
   The pollution produced by light trucks, SUVs and minivans is only half a percent higher than that produced by conventional cars, based on a recent study. But researchers say that this tiny difference becomes enormous when considering the number of light trucks moving along the nation's highways.

7. Researchers complete first clinical trial of Apatone for cancer treatment
   10-05-2007 · EurekAlert!
   In a significant advancement in the ongoing battle against cancer, a group of researchers from Summa Health System, IC-MedTech and other institutions have completed the first ever FDA-approved human clinical trial of Apatone. Demonstrating promising results, Apatone exploits a new strategy to selectively lower the level of compounds within tumor cells that assist in energy production and protect against chemotherapy. This non-toxic approach weakens and kills cancers in a novel way.

8. A vitamin B12 derivative could potentially be used to treat hypertension and heart disease
   11-23-2007 · EurekAlert!
   Nitric oxide is a very important regulator of blood pressure and blood flow to the heart and other organs. Several drugs such as nitroglycerin and sodium nitroprusside act by providing NO, but each of these drugs have drawbacks. Investigators at the University of California, San Diego have developed a drug that releases NO directly, which is unlikely to be toxic because it is a vitamin B12 derivative.

   02-16-2008 · EurekAlert!
   In his research, NOAA scientist Nat Scholz examines how pesticides that run off the land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system. These pesticides are widely used in the United States and their occurrence as mixtures in the food supply for humans may also pose an unexpected risk for people.

10. No magic tomato? Study breaks link between lycopene and prostate cancer prevention
    05-17-2007 · EurekAlert!
    Tomatoes might be nutritious and tasty, but don't count on them to prevent prostate cancer. In the May issue of Cancer Epidemiology, Biomarkers & Prevention, researchers based at the National Cancer Institute and Fred Hutchinson Cancer Research Center report that lycopene, an antioxidant predominately found in tomatoes, does not effectively prevent prostate cancer. In fact, the researchers noted an association between beta-carotene, an antioxidant related to lycopene, and an increased risk for aggressive prostate cancer.
