An invisible threat could change Britain's landscapes
People and farm animals are helping an invisible pollutant to change the types of plants that grow in Britain, particularly in remote and rural regions such as the Lake District. view more (2005-02-11)
Water and Nanoelectronics Will Mix to Create Ultra-Dense Memory Storage Devices, Researchers Say
Excessive moisture can typically wreak havoc on electronic devices, but now researchers have demonstrated that a little water can help create ultra-dense storage systems for computers and electronics. view more (2006-04-28)
Stunning finding: Compounds protect against cerebral palsy
Two compounds developed by Northwestern University chemists have been shown to be effective in pre-clinical trials in protecting against cerebral palsy, a condition caused by neurodegeneration that affects body movement and muscle coordination. view more (2009-02-25)
Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
Use of statins shows improvement in erectile performance of some men
Researchers at the University of Pennsylvania School of Medicine say preliminary results of a small study show promise in improving erectile dysfunction (ED) in men who had shown minimal reaction to Viagra. view more (2006-02-22)
Embryo's heartbeat drives blood stem cell formation
Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. view more (2009-05-14)
Organic solar power
Solar cells made from conventional semiconductor materials such as silicon are becoming increasingly common. By contrast, cells which use organic dyes or electrically conductive plastics are relatively unknown. At the Hanover Fair: prototypes of such cells and possible applications. ----------- If solar power is to be generated in the future on a... view more... (2002-04-16)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
Silica smart bombs deliver knock-out to bacteria
Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. view more (2008-02-26)
Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. view more (2008-09-24)
Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. view more (2007-09-28)
Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy. view more (2008-02-14)
Elevated arginase levels contribute to vascular eye disease such as diabetic retinopathy
Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy. view more (2009-08-18)
Portable and precise gas sensor could monitor pollution and detect disease
In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. view more (2009-09-21)
Military imagery analysis assistant
Friend or enemy - what kind of tank or ship can be seen in aerial or satellite photo? The RecceMan identification assistant, which helps recognize the most diverse objects quickly and accurately, is the first interactive image recognition system produced for the German army. view more (2001-12-03)
Researchers find new mechanism governing particle growth in nanocomposites
A research team from the Georgia Institute of Technology and Drexel University has discovered a surprising new mechanism by which polymer materials used in nanocomposites control the growth of particles. view more (2005-09-01)
Non Fire Yet But The Sensors Snap Into Action
Russian researchers offer a fundamentally new approach to the development of gas sensors for fire-prevention detecting devices. In contrast to already known ones, these sensors allow to detect unerringly fire occurrence at its earliest stage. However, this is not a single advantage of the innovation or a sole field of application. view more (2004-12-06)
More Than Meets the Eye: New Blue Light Nanocrystals
Berkeley Lab researchers have produced non-toxic magnesium oxide nanocrystals that efficiently emit blue light and could also play a role in long-term storage of carbon dioxide, a potential means of tempering the effects of global warming. view more (2009-07-22)
New technology shows promise against resistant staph infections
Scientists at Albert Einstein College of Medicine of Yeshiva University have combined their revolutionary new drug-delivery system with a powerful antimicrobial agent to treat potentially deadly drug-resistant staph infections in mice. view more (2009-05-01)
Sol-gel inks produce complex shapes with nanoscale features
New sol-gel inks developed by researchers at the University of Illinois can be printed into patterns to produce three-dimensional structures of metal oxides with nanoscale features. view more (2007-10-12)
