Southern pines appear to grow and conserve water somewhat better in the carbon-dioxide-enriched atmosphere expected by mid-century, a Duke University study has found. However, any growth spurts appear to diminish over time, due at least in part to the kind of hot and dry weather that likely may become more common in the future. Thus, the researchers concluded, enhanced growth of pines may not constitute a long-term sink for human-produced carbon dioxide which might ameliorate global warming.
These findings of a growth ring and wood chemistry study will be described by Duke graduate student Ashley Ballantyne at 9 a.m. Eastern Time on Tuesday, Aug. 9, 2005, during the Ecological Society of Americas 2005 national meeting in Montreal.
Ballantyne, a fourth-year doctoral student in paleoclimatology at Dukes Nicholas School of the Environment and Earth Sciences, did his study with research associate Jeffrey Pippen at the Free-Air Carbon Dioxide Enrichment (FACE) experiment http://face.env.duke.edu/main.cfm.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
