Texas A&M Researchers Examine How Viruses Destroy Bacteria
Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria. Texas A&M University researchers are exploring how hungry viruses, armed with transformer-like weapons, attack bacteria, which may aid in the treatment of bacterial infections. view more (2009-11-19)
First Bose-Einstein condensation of strontium
In an international first, scientists from the Institute of Quantum Optics and Quantum Information (IQOQI) produced a Bose-Einstein condensate of the alkaline-earth element strontium, thus narrowly winning an international competition between many first-rate scientific groups view more (2009-11-10)
PTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. view more (2009-11-06)
A new explanation of 'Asian paradox'
Although Helicobacter pylori (H. pylori) has been classified as a class I (or definite) carcinogen by World Health Organization (WHO), the controversy as to why only a minority of infected patients develop gastric cancer still remains. view more (2009-10-29)
Research Continues on Secure, Mobile, Quantum Communications

Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Berkeley researchers create first hyperlens for sound waves
Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based... view more...

Loss of tumor supressor gene essential to transforming benign nerve tumors into cancers
Researchers at UCLA's Jonsson Comprehensive Cancer Center showed for the first time that the loss or decreased expression of the tumor suppressor gene PTEN plays a central role in the malignant transformation of benign nerve tumors called neurofibromas into a malignant and extremely deadly form of sarcoma. view more (2009-10-13)
Police sketch artist evolves

Anemic Patients With MDS Gain Long-Term Benefits From Erythropoietin and Myeloid Growth Factor Hormones
Myelodysplastic syndromes (MDS), a group of blood disorders that can lead to acute myeloid leukemia (AML) in some patients, often cause severe anemia (when the body lacks a sufficient number of functional red blood cells). view more (2009-09-18)
Optics made to measure
If you are in the business of developing high-speed electronic components, it pays not to lose sight of the electrons. To keep track of them you will need to use dedicated optical elements, such as those now on offer from UltraFast Innovations GmbH. view more (2009-09-17)
Light at the speed of a bicycle and much more
The speed of light, 300 million metres per second, was long thought an immutable constant and has defined our understanding of matter and energy but recent research in the area of optics and photonics is proving that we can manipulate light to some ingenious and hugely lucrative ends. view more (2009-09-09)
Open wide and say 'zap'
A group of researchers in Australia and Taiwan has developed a new way to analyze the health of human teeth using lasers. view more (2009-08-19)
A new cloaking method
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures... view more... (2009-08-17)
Storm clouds over Titan
Taking advantage of advanced techniques to correct distortions caused by Earth's atmosphere, astronomers used the NSF-supported Gemini Observatory to capture the first images of clouds over the tropics of Titan, Saturn's largest moon. view more (2009-08-13)
Beyond the looking glass
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. view more (2009-08-13)
UCF scientists control living cells with light; advances could enhance stem cells' power
University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. view more (2009-08-12)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
