Estrogen activates critical lung genes to improve lung function following preterm birth
Estrogen may be a new postnatal therapy to improve lung function and other outcomes in preterm infants, researchers at UT Southwestern Medical Center have found in an animal study. view more (2009-03-12)
Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops
Deficiencies of micronutrients such as Iron and Zinc commonly limit plant growth and crop yields. Dartmouth Professor Mary Lou Guerinot is conducting research to better understand the mechanisms of micronutrient uptake, distribution and regulation. view more (2006-08-07)
Hypoxia training suppresses harmful cardiac nitric oxide production during heart attack
Researchers at the University of North Texas Health Science Center, Fort Worth, Texas have demonstrated that, contrary to prevailing dogma, hypoxia can be remarkably beneficial to the heart. These discoveries, to be reported in the June 2008 issue of Experimental Biology and Medicine, may lead to a new paradigm to protect hearts of patients at... view more... (2008-05-27)
A new hope for heavy metal contaminated soils
In the 1980s scientists began laboratory studies on metal hyperaccumulator plants, i.e. plants which accumulate exceptionally high concentrations of heavy metals in their above-ground biomass. This coincided with the recognition that a number of serious human diseases are the result of disruptions in metal homeostasis, for example Menke's disease,... view more... (2003-12-05)
Diabetes complications rooted in faulty cell repair
University of Florida researchers say primitive cells that act like molecular maintenance men-traveling throughout the body to repair damaged blood vessels-become too rigid to move in patients with diabetes, fueling the disease's vascular complications. view more (2006-01-26)
Purdue engineers create safer, more efficient nuclear fuel, model its performance
Purdue University nuclear engineers have developed an advanced nuclear fuel that could save millions of dollars annually by lasting longer and burning more efficiently than conventional fuels, and researchers also have created a mathematical model to further develop the technology. view more (2005-09-29)
Halting methane squanderlust
The pipes that rise from oil fields, topped with burning flames of natural gas, waste fossil fuels and dump carbon dioxide into the air. In new work, researchers have identified the structure of a catalytic material that can turn methane into a safe and easy-to-transport liquid. The insight lays the foundation for converting excess methane into a... view more... (2008-05-22)
Yale study: Not enough metals in earth to meet global demand
Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever, according to a study published in the Proceedings of the National Academy of Sciences. view more (2006-01-26)
Nano-cages 'fill up' with hydrogen
A "cagey" strategy to stack more hydrogen in nanoscale scaffoldings made of zinc-based boxes may yield a viable approach to storing hydrogen and, ultimately, replacing fossil fuels in future automobiles, according to new results from National Institute of Standards and Technology (NIST) researchers. view more (2005-12-02)
Breakthrough for the computer of tomorrow?
For the first time a material now exists that is not only a semiconductor but also exhibits exploitable magnetic properties at room temperature. Researchers at the Royal Institute of Technology (KTH) in Stockholm, Sweden, have taken the lead in an international race to find the technology of tomorrow. Today's computers process information using... view more... (2003-09-25)
Tiny Tubes and Rods Show Promise as Catalysts, Sunscreen
Scientists at the U.S. 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. view more (2007-09-11)
For the future hydrogen economy, a tiny, self-powered sensor
Hydrogen has been called "the fuel of the future." But the gas is invisible, odorless and explosive at high concentrations, posing a safety problem for hydrogen-powered cars, filling stations and other aspects of the so-called hydrogen economy. view more (2006-05-25)
Ovarian cancer responds to aspirin derivative with chemo
A new study using ovarian cancer cell lines shows promise in treating the deadly disease by combining the chemotherapy drug cisplatin with an aspirin-like compound to make recurrent cancer cells less resistant to the chemotherapy. view more (2006-02-16)
Looking deeply into polymer solar cells
Researchers from the Eindhoven University of Technology and the University of Ulm have made the first high-resolution 3D images of the inside of a polymer solar cell. view more (2009-09-14)
New beryllium reference material for occupational safety monitoring
Researchers at the National Institute of Standards and Technology (NIST), in collaboration with private industry and other government agencies, have produced a new reference material for beryllium. view more (2009-09-23)
New clues to how sex evolves
Sex is a boon to evolution; it allows genetic material from parents to recombine, giving rise to a unique new genome. But how did sex itself evolve\\\ view more (2006-12-05)
Nanomanufacturing: Systematic study of nanostructure growth yields production 'road map'
Researchers have taken an important step toward high-volume production of new nanometer-scale structures with the first systematic study of growth conditions that affect production of one-dimensional nanostructures from the optoelectronic material cadmium selenide (CdSe). view more (2005-11-01)
Widely used iron nanoparticles exhibit toxic effects on neuronal cells
Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions. view more (2007-03-29)
Researchers Reveal How Air Pollutant Helps Pregnant Women with Hypertension
Nitric oxide (NO) is best known as an air pollutant produced by vehicle emissions and power plants but for pregnant women it is a crucial compound required to avoid hypertension and pre-eclampsia. view more (2006-09-21)
Research helps understand factors that influence efficiency of organic-based devices
Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce more light. view more (2008-07-09)
