Mon, 02 Jun 2008 How Enzyme Works: A Molecular Switch Turns On The Flame In "Nature"s Blowtorch". Uncontrolled reaction of organic compounds with oxygen is easy: we call it fire. But nature often needs to do oxidations very specifically, adding oxygen to a particular carbon atom in a complicated molecule without disturbing anything else. Usually, this job falls to an enzyme called cytochrome P450.more

Tue, 27 May 2008 Electron Traps That Compute. Physicists have used a semiconductor material to create superimposed quantum dots that "trap" single electrons. Not only can these dots be studied with lasers, their energy can be influenced as well. Another point: the state of one of the dots governs that of the other above it. This has taken the researchers another step closer to quantum computers.more

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
