Thu, 22 May 2008 Scientists Develop Way To Predict Properties Of Light Nuclei. Scientists have spent 70 years trying to predict the properties of nuclei, but have had to settle for approximate models because computational techniques were not equal to the task. Scientists at U.S. Department of Energy"s Argonne National Laboratory have learned to compute what happens when nuclei collide.more

Wed, 07 May 2008 Researchers Find Way To Make Tumor Cells Easier To Destroy. Radiation oncology researchers found that tumors have a built-in mechanism that protects them from heat damage and most likely decreases the benefit of hyperthermia and radiation as a combined therapy. By interfering with that protection, the researchers have shown that tumor cells grown in culture can be made more sensitive to hyperthermia-enhanced radiation therapy.more

Tue, 22 Apr 2008 Water Needed To Produce Various Types Of Energy. It is easy to overlook that most of the energy we consume daily, such as electricity or natural gas, is produced with the help of a dwindling resource -- fresh water. Scientists are researching the water-efficiency of some of the most common energy sources and power generating methods.more

Tue, 15 Apr 2008 Scientists Find A Surprise When They Look For What Binds In Superconductivity. For more than 20 years since the discovery of high-temperature superconductivity, scientists have been debating the underlying physical mechanism for this exotic phenomenon. Now, provocative results yielded by two years of experiments carried out at Princeton University have a group of scientists saying that high-temperature superconductivity does not hinge on a magical glue binding electrons together. The secret to superconductivity, they say, may rest instead on the ability of electrons to take advantage of their natural repulsion in a complex situation.more
