Whispering bats are 100 times louder than previously thought
Annemarie Surlykke from the University of Southern Denmark is fascinated by echolocation. She really wants to know how it works. Surlykke equates the ultrasound cries that bats use for echolocation with the beam of light from a torch: you won't see much with the light from a small bulb but you could see several hundred metres with a powerful beam. view more (2008-12-12)
New treatment finds success treating tiniest lung tumors
Patients with metastatic cancer tumors in their lungs are much more likely to live disease-free if they have an experimental treatment involving shaped-beam radiosurgery rather that conventional treatment. view more (2006-11-09)
The sweet smell of nano-success
Materials scientists at Lehigh University and catalyst chemists at Cardiff University have uncovered secrets of the "nanoworld" that promise to lead to cleaner methods of producing, among other things, spices and perfumes. view more (2006-01-30)
Laser Instead Of A Diamond Saw
St. Petersburg physicists have developed a plant that allows to cut sapphire crystals into almost ideally smooth plates being fractions of millimeter thick. The approach suggested by the researchers fundamentally differs from the traditional one. They suggest that sapphire should not be sawn by a saw, but split by laser. view more (2004-10-22)
Putting the heat on components
Europe's most modern facility for testing large, heat-resistant components used in fusion devices is now in operation at Max-Planck-Institut für Plasmapyhsik (IPP) in Garching near Munich. The special feature of GLADIS (Garching Large Divertor Sample Test Facility): The heat test facility is suitable for investigating not only small samples... view more... (2005-02-16)
ORNL, Protein Discovery researchers collaborate on high-profile paper
A paper that outlines a new method to use a beam of light to trap protein molecules and make them dance in space has earned a place in the Proceedings of the National Academy of Sciences Early Edition. view more (2006-04-13)
EU Support for Two Projects Coordinated by DESY
The European Commission selected two projects coordinated by the DESY research center in Hamburg for support within its sixth Framework Programme. Among all the competitors for the much-coveted development funds, the projects "EUROFEL" and "EUROTeV" were ranked first and second, respectively, in the referees' evaluation. From... view more...

Tunable semiconductors possible with hot new material called graphene
Today's transistors and light emitting diodes (LED) are based on silicon and gallium arsenide semiconductors, which have fixed electronic and optical properties. view more (2009-06-11)
Boston physicists celebrate first beam for Large Hadron Collider
Scientists today sent the first beam of protons zooming at nearly the speed of light around the 17-mile Large Hadron Collider. The LHC, located at the CERN laboratory near Geneva, Switzerland, is the world's most powerful particle accelerator. view more (2008-09-10)
New hybrid microscope probes nano-electronics
A new form of scanning microscopy that simultaneously reveals physical and electronic profiles of metal nanostructures has been demonstrated at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and University of Colorado at Boulder. view more (2006-10-30)
Researchers develop foundation for circuitry and devices based on graphite
Graphite, the material that gives pencils their marking ability, could be the basis for a new class of nanometer-scale electronic devices that have the attractive properties of carbon nanotubes - but could be produced using established microelectronics manufacturing techniques. view more (2006-03-15)
With double frequency to deeper blue
Light transports data at high speed over fibre-optic networks. Light measures and creates images of large and small objects in scanners and microscopes. Light writes information onto all sorts of recording media and surfaces. The best-quality light is produced by lasers, which have meanwhile become an indispensable tool - not only in medicine and... view more... (2003-07-01)
Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme. view more (2006-04-06)
Ytterbium's Broken Symmetry
Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame. view more (2009-07-23)
Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins. Like a line of silent ballet dancers, long-chain... view more... (2004-05-14)
Researcher solve one mystery of high-temperature superconductors
Unlike low-temperature superconductors, which are metals, high-temperature superconductors are insulators in their normal state. This has puzzled scientists, because half of the electron states are empty. view more (2005-11-29)
Hormone therapy for prostate cancer patients with heart conditions linked to increased death risk
Men with coronary artery disease-induced congestive heart failure or heart attack who receive hormone therapy before or along with radiation therapy for treatment of prostate cancer have an associated increased risk of death. view more (2009-08-26)
Nanotube flickering reveals single-molecule rendezvous
In the quantum world, photons and electrons dance, bump and carry out transactions that govern everything we see in the world around us. view more (2007-06-08)
Cloudy day won't rain on laser communications
Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds. view more (2006-11-13)
Molecular Anatomy of Influenza Virus Detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes influenza. view more (2007-01-02)
