Professor working on practical cloaking device (w/ Video)
(PhysOrg.com) -- A physicist at the University of St Andrews hopes to make major advances in the 'tantalising' field of invisibility in the next two years. Professor Ulf Leonhardt, who...
Dark Energy's Demise? New Theory Doesn't Use the Force
The repulsive force thought to explain why the universe's expansion is speeding up may not be necessary, according to a new model that says the acceleration is just an illusion.
Gold nanoparticles detect cancer
Ultrasensitive detection platform uses nanoparticles to measure levels of cancer biomarkers
Scientists use self-assembled DNA scaffolding to build tiny circuit boards
Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Centre have developed a new technique to orient and position self-assembled DNA shapes and patterns - or 'DNA...
New DNA Test Uses Nanotechnology To Find Early Signs Of Cancer
Using tiny crystals called quantum dots, researchers have developed a highly sensitive test to look for DNA attachments that often are early warning signs of cancer.
Aquatic Worm Holds The Key to New Bone-Setting Glue
Creating an adhesive that can bond together bones has long presented researchers with some sticky problems. Many glues will not adhere to slick, wet surfaces, and those that do still tend to dissolve...
Plastic semiconductor is created
SEATTLE, Aug. 18 (UPI) -- U.S. scientists say they have created an organic polymer semiconductor that transports both positive and negative charges.
Confined electrons live longer
Electrons that are trapped in very small structures of only a few nanometer, demonstrate fascinating features. These could be useful for novel computers or semiconductor lasers. Researchers from the University...
Nanocapsules used for drug delivery
PITTSBURGH, Aug. 18 (UPI) -- University of Pittsburgh scientists say they have created nanoscale devices for drug or imaging agent delivery and to enhance oxygen sensors.
Researcher says microchannels could advance tissue engineering methods
Utilising fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A and M University, has created...
Chemist creates trapping technique for nanoparticles
(PhysOrg.com) -- A chemist at the University of Wisconsin-Milwaukee (UWM) has developed a kind of invisible fence for trapping and controlling particles as small as a single virus or large...
Imaging the inner workings of single molecules
With $20 million over five years from the National Science Foundation, UC Irvine scientists hope to become the first ever to make real-time videos of single molecules in action -...
UGA, UPR grant license for long-persistence glow materials, in any color
The University of Georgia Research Foundation, Inc. (UGARF) and the University of Puerto Rico have granted an international, non-exclusive license for a portfolio of glow-in-the-dark pigments that can be designed...
New low emission coal technology will provide double power, reduce costs and help the environment
(PhysOrg.com) -- A University of Queensland researcher has successfully completed a lab-scale test on a new technology which has the potential to revolutionise the way the world views and uses...
Good Vibrations Generate Electricity
Relying on the piezoelectric effect, a new device harvests energy from tiny vibrations.
Tiny robots get a grip on nanotubes
(PhysOrg.com) -- How do you handle the tiny components needed for constructing nanoscale devices? A European consortium has built two microrobotic demonstrators that can automatically pick up and install carbon...
Vanquishing infinity
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have...
New material for nanoscale computer chips
Nanochemists from the Chinese Academy of Sciences and Nano-Science Centre, Department of Chemistry at University of Copenhagen have developed nanoscale electric contacts out of organic and inorganic nanowires. In the...
English Wikipedia hosts three millionth article
The English version of user-generated online encylopedia Wikipedia hosted its three millionth article on Monday -- an entry about a Norwegian actress.
Molten Proteins: Surface-modified liquid protein with liquid-crystalline properties
(PhysOrg.com) -- Proteins are solids. When heated they do not melt; instead, they decompose or sublime directly to the gas phase at low pressures. They cannot be converted into a...
Profiling The Scent Of Death
Solid-phase microextraction coupled with gas chromatography/mass spectrometry captures chemical profiles of decomposition.
Arabic chemists from the 'Golden Age' given long overdue credit
You've heard of Louis Pasteur and George Washington Carver, no doubt. And probably Joseph Priestley, one of the founders of modern chemistry. Names like Antoine Lavoisier, John Dalton, and Amadeo...
DNA 'organises itself' on silicon
Researchers have shown that engineered, self-organising DNA chunks could be used to build smaller, faster computers.
Smoke-spewing Trabant poised for rebirth as electric car
Once the much-mocked symbol of drab communist East Germany, Trabant cars are revving up for a dramatic rebirth as electric cars -- 20 years after they drove through the fallen...
Nanotubes promise ultra-small wearable oxygen sensors
Tiny personal oxygen sensors could make working in submarines and space shuttles safer
Catalyst free carbon-carbon bond formation
Researchers develop a simple, one-pot reaction to create carbon-carbon bonds at a carbonyl group without a metal catalyst
Physicists Make Crystal-Liquid Interface Visible For First Time
Researchers have captured the first images of what's actually happening in the fuzzy area of the crystal-liquid interface. Their lab's data make the waves between the two states of matter,...
New study: Up to 90 percent of US paper money contains traces of cocaine
WASHINGTON, Aug. 16, 2009 -- You probably have cocaine in your wallet, purse, or pocket. Sound unlikely or outrageous? Think again!
