CORVALLIS, Ore. – A large, global move to produce more energy from forest biomass may be possible and already is beginning in some places, but scientists say in a new analysis that such large-scale bioenergy production from forest biomass is unsustainable and will increase greenhouse gas emissions.

A new genre of electric power-generating stations could supply electricity for more than a half billion people by tapping just one-tenth of the global potential of a little-known energy source that exists where rivers flow into the ocean, a new analysis has concluded. A report on the process — which requires no fuel, is sustainable and releases no carbon dioxide (the main greenhouse gas) — appears in ACS' journal Environmental Science & Technology.
In this week's PLoS Medicine, Luis Montaner from the Wistar Institute, Philadelphia, USA and colleagues retrospectively apply a potential capacity-saving CD4 count model to a cohort of HIV-infected patients on antiretroviral therapy. The study's findings suggest that the model could be used to optimize laboratory capacity in settings where resources are limited.
In wealthy countries, antiretroviral therapy (ART) has transformed AIDS into an often-manageable chronic condition, as patients can receive both the therapeutics and the constant monitoring that ensures the therapies remain effective. Developing nations, however, frequently need to balance expansion of treatment access versus the economic resources to sustain the routine blood testing that ART requires. At a time when global funding commitments for AIDS therapy programs are being cut, there is a great need to find new strategies to maximize available resources.
HOUSTON – (April 17, 2012) – Forests of carbon nanotubes are an efficient alternative for platinum electrodes in dye-sensitized solar cells (DSC), according to new research by collaborators at Rice University and Tsinghua University.
The public and press can see the latest progress in a unique, ongoing electromobility research project during the international trade fair MobiliTec, which takes place April 23-27 at the Hannover Messe. Embodied in a sleek, Colani-designed tractor-trailer that looks more like a spaceship than a truck, the project "Diesel Reloaded" aims to demonstrate how paradigm shifts in automotive, energy, and information technologies can help to address major societal trends and needs. The research group, based at the Technische Universitaet Muenchen, is led by Prof. Dr.
Two years ago this week, oil began streaming from the seafloor into the Gulf of Mexico following the explosion of the Deepwater Horizon platform. All told, the disaster cost 11 lives, released 4.9 million barrels of crude oil, and caused still unspecified impacts to marine life and the Gulf economy.

EAST LANSING, Mich. — Far too many K-12 students have inadequate writing skills, and the current efforts to improve instruction in the United States may be more challenging than anticipated, research from Michigan State University shows.
According to an initial sample of seven states, the existing standards for teaching writing vary widely in comparison to a new set of common standards that are in the process of being implemented by most states.
For Immediate Release – April 17, 2012 - (Toronto) People with an opioid addiction had the highest risk of death when compared with rates for alcohol and other drugs, according to a new study by the Centre for Addiction and Mental Health (CAMH).
(Santa Barbara, Calif. –) A new quantum mechanical-based biosensor designed by a team at University of California, Santa Barbara offers tremendous potential for detecting biomolecules at ultra-low concentrations, from instant point-of-care disease diagnostics, to detection of trace substances for forensics and security.
Overall, 17% of children in the United States are obese, and in inner-city neighborhoods, the prevalence is as high as 25%. While poor diets and physical inactivity are the main culprits, there is new evidence that air pollution can play a role.
Researchers at Rice University and Penn State University have discovered that adding a dash of boron to carbon while creating nanotubes turns them into solid, spongy, reusable blocks that have an astounding ability to absorb oil spilled in water.
That's one of a range of potential innovations for the material created in a single step. The team found for the first time that boron puts kinks and elbows into the nanotubes as they grow and promotes the formation of covalent bonds, which give the sponges their robust qualities.
New research from North Carolina State University shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter (PM) and nitrogen oxides (NOx) – pollutants that have significant human health and environmental impacts.
