Study of atomic movement may influence design of pharmaceuticals
Chemists at the University of Liverpool have designed a unique structure to capture the movement of atoms which may impact on future designs of pharmaceuticals.
From farm waste to fuel tanks
Using corncob waste as a starting material, researchers have created carbon briquettes with complex nanopores capable of storing natural gas at an unprecedented density of 180 times their own volume and at one seventh the pressure of conventional natural gas tanks.
Unique tomatoes tops in disease-fighting antioxidants
Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use.
New insights into high-temperature superconductors
Scientists at the Carnegie Institution's Geophysical Laboratory in collaboration with a physicist at the Chinese University of Hong Kong have discovered that two different physical parameters —pressure and the substitution of different isotopes of oxygen (isotopes are different forms of an element) —have a similar effect on electronic properties of mysterious materials called high-temperature superconductors.
Scientists invent real-life 'tricorder' for chemical analysis
Purdue University researchers have created a handheld sensing system its creators liken to Star Trek's "tricorder" used to analyze the chemical components of alien worlds. But the system could have down-to-earth applications, such as testing foods for dangerous bacterial contaminants including salmonella, which was recently found in a popular brand of peanut butter.
Catalyst breakthrough boosts hydrogen fuel cells
Researchers at the U.S. Department of Energy's Argonne National Laboratory have discovered new information on the behavior of nano-engineered platinum surfaces – information that may bring polymer electrolyte membrane fuel cells for hydrogen-powered vehicles another step closer to full development.
Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
Antifreeze or "ice structuring" proteins – found in some fish, insects, plants, fungi and bacteria – attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. Scientists have been puzzled, however, about why some ice structuring proteins, such as those found in the spruce budworm, are more active than others.
How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in.
Transported black carbon a significant player in pacific ocean climate
More than three-quarters of the particulate pollution known as black carbon transported at high altitudes over the West Coast during spring is from Asian sources, according to a research team led by Professor V. Ramanathan at Scripps Institution of Oceanography, UC San Diego.
Hydrogel particles pave way for new bedside diagnostics
MIT researchers have created an inexpensive method to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample--a technology that could make possible the development of low-cost clinical bedside diagnostics.

Mechanics meets chemistry in new ways to manipulate matter
The inventors of self-healing plastic have come up with another invention: a new way of doing chemistry.
Mit biologists solve vitamin puzzle
Solving a mystery that has puzzled scientists for decades, MIT and Harvard researchers have discovered the final piece of the synthesis pathway of vitamin B12--the only vitamin synthesized exclusively by microorganisms.
Ice created in nanoseconds by sandias z machine
Sandia's huge Z machine, which generates temperatures hotter than the sun, has turned water to ice in nanoseconds.
Rna enzyme structure offers a glimpse into the origins of life
Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules. Their results provide insight into what may have been the first self-replicating molecule to arise billions of years ago on the evolutionary path toward the emergence of life.
Chemists strike gold with new gold catalysts
A University of California, Berkeley, chemist has found a mother lode of new and unique gold-catalyzed reactions by applying Einstein's theory of relativity to the rare and precious metal.
Nanotubes could improve thermal management in electronics
As the electronics industry continues to churn out smaller and slimmer portable devices, manufacturers have been challenged to find new ways to combat the persistent problem of thermal management. New research published in the March 19 issue of Applied Physics Letters suggests that carbon nanotubes may soon be integrated into ever-shrinking cell phones, digital audio players, and personal digital assistants to help ensure the equipment does not overheat, malfunction, or fail.
Seeking the next kevlar
A team of University of Pennsylvania and Rice University researchers have added a significant new step to the creation of materials fortified by single-walled carbon nanotubes, or SWNTs, resulting in a nylon polymer composite with greater strength and toughness and opening the door for researchers to broadly improve the mechanical properties of such composites at the molecular level.
Technique creates metal memory and could lead to vanishing dents
Crumpled kitchen foil that lays flat for reuse. Bent bumpers that straighten overnight. Dents in car doors that disappear when heated with a hairdryer. These and other physical feats may become possible with a technique to make memory metals discovered by researchers at the University of Illinois.
Scientists unlock physical, chemical secrets of plutonium
Researchers at Rutgers, The State University of New Jersey, have unlocked some of the physical and chemical secrets of plutonium, an element known for its use in atomic weapons and power plant fuel. While the complex nuclear characteristics of plutonium are well-known, it has properties as a metal or a chemical compound that have often left scientists scratching their heads.
Organic lighting research burns bright
The long, challenging technological march from the low-power light bulb Thomas Edison invented to the ultimate in a bright and energy-efficient lighting device may reach fruition in work led by the two ASU researchers.
