Algae could one day be major hydrogen fuel source
As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks. Scientists at U.S. Department of Energy's Argonne National Laboratory are answering that call by working to chemically manipulate algae for production of the next generation of renewable fuels – hydrogen gas.
DVDs and CD-ROMs that thwart global warming
Carbon dioxide removed from smokestack emissions in order to slow global warming in the future could become a valuable raw material for the production of DVDs, beverage bottles and other products made from polycarbonate plastics, chemists are reporting.
Newly discovered 'superinsulators' promise to transform materials research, electronics design
Superinsulation may sound like a marketing gimmick for a drafty attic or winter coat. But it is actually a newly discovered fundamental state of matter created by scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with several European institutions. This discovery opens new directions of inquiry in condensed matter physics and breaks ground for a new generation of microelectronics.
Researchers make breakthrough in creating gasoline from plant matter, with almost no carbon footprint
Researchers have made a breakthrough in the development of "green gasoline," a liquid identical to standard gasoline yet created from sustainable biomass sources like switchgrass and poplar trees.
Manufactured buckyballs don't harm microbes that clean the environment
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers.
Hydrogen storage in nanoparticles works
Dutch chemist Kees Baldé has demonstrated that hydrogen can be efficiently stored in nanoparticles. This allows hydrogen storage to be more easily used in mobile applications. Baldé discovered that 30 nanometre particles of the metal hydride sodium alanate make the favourable extraction and storage of hydrogen possible.
Popcorn-ball design doubles efficiency of dye-sensitized solar cells
A new approach is able to create a dramatic improvement in cheap solar cells now being developed in laboratories.
New technique yields more detailed picture of chromatin structure
University of Illinois researchers have developed a technique for imaging cells under an electron microscope that yields a sharper image of the structure of chromatin, the tightly wound bundle of genetic material and proteins that makes up the chromosomes.
Ceramic, heal thyself
A new computer simulation has revealed a self-healing behavior in a common ceramic that may lead to development of radiation-resistant materials for nuclear power plants and waste storage.
New source for biofuels discovered by researchers
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up.

Berkeley researchers find new details following the path of solar energy during photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. That's the promise of artificial versions of photosynthesis, the process by which green plants have been converting solar energy into electrochemical energy for millions of years. To get there, however, scientists need a far better understanding of how Nature does it, starting with the harvesting of sunlight and the transporting of this energy to electrochemical reaction centers.
Copper nanowires grown by new process create long-lasting displays
A new low-temperature, catalyst-free technique for growing copper nanowires has been developed by researchers at the University of Illinois. The copper nanowires could serve as interconnects in electronic device fabrication and as electron emitters in a television-like, very thin flat-panel display known as a field-emission display.
Boost for green plastics from plants
Australian researchers are a step closer to turning plants into 'biofactories' capable of producing oils which can be used to replace petrochemicals used to manufacture a range of products.
Microbes could boost world energy supply
British and Canadian scientists expect to begin trials to find out whether microbes can unlock the vast amount of energy trapped in the world's unrecoverable heavy oil deposits.
Diatoms discovered to remove phosphorus from oceans
Scientists at the Georgia Institute of Technology have discovered a new way that phosphorus is naturally removed from the oceans – it's stored in diatoms. The discovery opens up a new realm of research into an element that's used for reproduction, energy storage and structural materials in every organism. Its understanding is vital to the continued quest to understand the growth of the oceans.
Ponds found to take up carbon like world's oceans
Research led by Iowa State University limnologist, or lake scientist, John Downing finds that ponds around the globe could absorb as much carbon as the world's oceans.
Limitations of charcoal as an effective carbon sink
Fire-derived charcoal is thought to be an important carbon sink. However, a SLU paper in Science shows that charcoal promotes soil microbes and causes a large loss of soil carbon.
'Crispy noodle' chemistry could reduce carbon emissions
A new material developed in Manchester, which has a structure that resembles crispy noodles, could help reduce the amount of carbon dioxide being pumped out and drive the next generation of high-performance hydrogen cars.
Researchers tackling unsolved questions about protein structures
A University of Arizona research team is exploring the evolutionary origins of protein structures. Their findings will help people better understand how proteins evolved to carry out the instructions encoded in the genes of every living thing.
From coal dust to carbon credits
UNSW scientists have turned the ash waste from coal-fired power stations into a global environmental solution which promises to slash emissions in the carbon-hungry construction sector by at least 20 per cent.
