Scientists at the US Department of Energy's Brookhaven National Laboratory provide further evidence that a drug known as D-cycloserine could play a role in helping to extinguish the craving behaviors associated with drug addiction. Their study found that mice treated with D-cycloserine were less likely to spend time in an environment where they had previously been trained to expect cocaine than mice treated with a placebo.

Kyle Cranmer, a former Goldhaber Distinguished Fellow and a current guest scientist at the US Department of Energy's Brookhaven National Laboratory was among 58 researchers honored in Washington, D.C., today as recipients of the prestigious Presidential Early Career Award for Scientists and Engineers.

A brain-imaging study of genetically obese rats conducted at the US Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine -- a brain chemical associated with reward, pleasure, movement, and motivation -- plays a role in obesity. The scientists found that genetically obese rats had lower levels of dopamine D2 receptors than lean rats. They also demonstrated that restricting food intake can increase the number of D2 receptors, partially attenuating a normal decline associated with aging.

Scientists at the US Department of Energy's Brookhaven National Laboratory have developed a method for correlating the results of microscopic imaging techniques in a way that could lead to improved understanding, diagnosis and possibly treatment of a variety of disease conditions, including Alzheimer's disease.

Based in part on protein structures determined at the National Synchrotron Light Source at the US Department of Energy's Brookhaven National Laboratory, scientists at the University of Utah have developed new peptides that appear to be significantly more effective at blocking HIV's entry into cells than other drugs in their class. These peptides are sufficiently potent to begin preclinical studies as a new class of agents for the prevention and treatment of HIV/AIDS.

A team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory have overcome a major obstacle for using refractive lenses to focus X-rays. This method will allow the efficient focusing of X-rays down to extremely small spots and is an important breakthrough in the development of a new, world-leading light source facility that promises advances in nanoscience, energy, biology and materials research.

Scientists at the US Department of Energy's Brookhaven National Laboratory have developed a new method for controlling the self-assembly of nanometer and micrometer-sized particles. The method, based on designed DNA shells that coat a particle's surface, can be used to manipulate the structure -- and therefore the properties and potential uses -- of numerous materials that may be of interest to industry.

Scientists at the US Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. The methods and new titanium oxide materials may lead to improved catalysts for hydrogen production, more efficient solar cells, and more protective sunscreens.

Using DNA, researchers at the US Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. Mathew Maye, a chemist in Brookhaven's newly opened Center for Functional Nanomaterials, will present the latest findings in this field at the 234th National Meeting of the American Chemical Society.

In an effort to develop alternative energy sources such as fuel cells and solar fuel from "artificial" photosynthesis, scientists at the US Department of Energy's Brookhaven National Laboratory are taking a detailed look at electrons. Understanding and controlling the movement of electrons through individual molecules could allow for new and improved energy technologies. Three Brookhaven chemists will discuss their most recent findings in this field at the 234th National Meeting of the American Chemical Society.
