New technique captures chemical reactions in a single living cell for the first time
Bioengineers at the University of California, Berkeley, have discovered a technique that for the first time enables the detection of biomolecules' dynamic reactions in a single living cell.
Biodiesel could reduce greenhouse gas emissions
A CSIRO report released today confirms that using pure biodiesel or blending biodiesel with standard fuel could reduce greenhouse gas emissions from the transport sector.
Catalyst-free chemistry makes self-healing materials more practical
A new catalyst-free, self-healing material system developed by researchers at the University of Illinois offers a far less expensive and far more practical way to repair composite materials used in structural applications ranging from airplane fuselages to wind-farm propeller blades.
Between water and rock -- a new science
Water chemistry and mineralogy are scientific fields that have been around long enough to develop extensive knowledge and technologies. The boundary of water and rock, however, is not a thin wet line but the huge new field of nanoparticle science.
Blue dye could hold the key to super processing power
A technique for controlling the magnetic properties of a commonly used blue dye could revolutionise computer processing power, according to research published recently in Advanced Materials.
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate.
Energy from abandoned oil reserves
Researchers from Newcastle University and Calgary University in Canada think they may have found a way of extracting more energy from the world's oil reserves.
New biochip could replace animal testing
With the cosmetics industry facing a European ban on animal testing in 2009, a newly developed biochip could provide the rapid analysis needed to insure that the chemicals in cosmetics are nontoxic to humans.
Metal foam has a good memory
In the world of commercial materials, lighter and cheaper is usually better, especially when those attributes are coupled with superior strength and special properties, such as a material's ability to remember its original shape after it's been deformed by a physical or magnetic force.
Explosives on a chip improve military detonators
Tiny copper structures with pores at both the nanometer and micron size scales could play a key role in the next generation of detonators used to improve the reliability, reduce the size and lower the cost of certain military munitions.

Hybrid semiconductors show zero thermal expansion; could lead to hardier electronics and optoelectronics
The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity — and not incidentally, ruin the chip. Thermal expansion can also separate semiconducting materials from the substrate, reduce performance through changes in the electronic structure of the material or warp the delicate structures that emit laser light.
Elevated carbon dioxide changes soil microbe mix below plants
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide (CO2) reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen. These changes could increase the availability of essential soil nutrients, thereby supporting increased plant growth and the plants' ability to "lock up," or sequester, excess carbon from the atmosphere.
Nylon reveals its antibiotic powers
Nylon, we know, is incredibly versatile, strong and resilient. Now, it may be possible to add antibiotic powers to the list of qualities for the wonder synthetic material.
Why don't we get cancer all the time?
The seemingly inefficient way our bodies replace worn-out cells is a defense against cancer, according to new research.
Smaller is stronger
As structures made of metal get smaller — as their dimensions approach the micrometer scale (millionths of a meter) or less — they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length. Many theories have been proposed to explain why smaller is stronger, but only recently has it become possible to see and record what's actually happening in tiny structures under stress.
Magnetic alloy with swiss cheese structure morphs shape
Researchers have turned a stubborn alloy into a shape-shifting foam by just giving it a little breathing room.
Materials' crystal properties illuminated by mathematical 'lighthouse'
A deeper fundamental understanding of complex materials may now be possible, thanks to a pair of Princeton scientists who have uncovered a new insight into how crystals form.
New buffer resists ph change, even as temperature drops
Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory samples to lose their efficacy as the samples are cooled. The research team, headed by chemistry professor Yi Lu, developed a method to formulate a buffer that maintains a desired pH at a range of low temperatures.
Helium isotopes point to new sources of geothermal energy
In a survey of the northern Basin and Range province of the western United States, geochemists Mack Kennedy of the Department of Energy's Lawrence Berkeley National Laboratory and Matthijs van Soest of Arizona State University have discovered a new tool for identifying potential geothermal energy resources.
Scientists develop low-cost, 'green' antimicrobial paint
Researchers at Rice University and the City College of New York (CCNY) have developed a low-cost, environmentally friendly technique for embedding antimicrobial silver nanoparticles into vegetable oil-based paints.

| Quotes | Ive always wanted to be a scientist. That way, I could get a bunch of grants and do research into whether money can really buy happiness.
Kyannke.
Ive always wanted to be somebody, but I see now I should have been more specific.
