New Developments in "Artificial Photosynthesis"

03-27-2007 · Brookhaven National Laboratory

Scientists at Brookhaven are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.

New developments in 'artificial photosynthesis'
03-27-2007 · EurekAlert!
Scientists at Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a system that can produce methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy. Four Brookhaven chemists will discuss their research on this "artificial photosynthesis" at the 233rd National Meeting of the American Chemical Society.

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts
06-15-2007 · EurekAlert!
University of Pittsburgh School of Medicine investigators have engineered artificial blood vessels from muscle-derived stem cells and a biodegradable polymer that exhibit extensive remodeling and remain free of blockages when grafted into rats. This development has potentially significant implications for the treatment of heart and kidney diseases, where there is a critical need for new sources of blood vessels for vascular grafts.

First direct electric link between neurons and light-sensitive nanoparticle films created
02-27-2007 · EurekAlert!
The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan. The development opens the door to applying the unique properties of nanoparticles to a wide variety of light-stimulated nerve-signaling devices -- including the possible development of a nanoparticle-based artificial retina.

Location, location, location
10-24-2007 · EurekAlert!
As housing developments sprout across the United States, smart growth proponents have urged communities to cluster developments in concentrated pockets, instead of the more standard and familiar "sprawl." Now a study in this month’s Ecological Applications, a journal of the Ecological Society of America, finds that while cluster development is indeed much easier on the surrounding environment, the location of housing developments is key.

Researchers create artificial enzyme that mimics the body's internal engine
03-15-2007 · EurekAlert!
Cytochrome c oxidase (CcO) is the ultimate enzyme responsible for all aerobic life on Earth. It's also a crucial component of the cellular machinery that generates energy in our body. Now Stanford University scientists have built a new model of the enzyme's active site that could one day help researchers gain insights into the causes of cancer and other major diseases, and might even prove useful in the development of new forms of alternative energy.
