Light and sound -- the way forward for better medical imaging
Detection and treatment of tumours, diseased blood vessels and other soft-tissue conditions could be significantly improved, thanks to an innovative imaging system being developed that uses both light and sound. view more (2007-12-13)
New technique sheds light on Alzheimer’s and CJD
Researchers using laser light fired at proteins believe they could be close to identifying the molecular architecture that predisposes certain proteins to become ‘corrupted’ and misfold, causing diseases such as Parkinson’s, Alzheimer’s and the spongiform encaphalopathies, CJD, BSE and scrapie. A new technique, invented by... view more... (2000-11-16)
Theoretical blueprint for invisibility cloak reported
Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. view more (2006-05-26)
Team develops new metamaterial device
An engineered metamaterial proved it can function as a state-of-the-art device in the complex terahertz range of the electromagnetic spectrum, setting a standard of performance for modulating tiny waves of radiation, according to a team of researchers from Boston College, the Los Alamos and Sandia national laboratories, and Boston University. view more (2009-02-25)
'Flying Fish' unmanned aircraft takes off and lands on water
Flying fish were the inspiration for an unmanned seaplane with a 7-foot wingspan developed at the University of Michigan. The autonomous craft is believed to be the first seaplane that can initiate and perform its own takeoffs and landings on water. view more (2007-12-06)
Computer simulations strongly support new theory of Earth's core
Swedish researchers present in today's Web edition of the journal Science evidence that their theory about the core of the earth is correct. Among other applications, the findings may be of significance for our understanding of the cooling down of the earth, and of the stability of the earth's magnetic field. view more (2008-02-11)
The impact of its environment on a quantum computer
Scientists have discovered how the performance of a quantum computer can be affected by its surrounding environment. The study, published in the latest issue of the journal Science, will help engineers to better understand how to integrate quantum components into a standard office computer - moving us one step closer to a future of quantum... view more...

Caltech scientists offer new explanation for monsoon development
Geoscientists at the California Institute of Technology have come up with a new explanation for the formation of monsoons, proposing an overhaul of a theory about the cause of the seasonal pattern of heavy winds and rainfall that essentially had held firm for more than 300 years. view more (2008-07-22)
Penn Researchers Pinpoint the Brain Waves That Distinguish False Memories From Real Ones
For the first time, researchers at the University of Pennsylvania are able to pinpoint brain waves that distinguish true from false memories, providing a better understanding of how memory works and creating a new strategy to help epilepsy patients retain cognitive function. view more (2007-10-24)
St. Jude study solves mystery of mammalian ears
A 30-year scientific debate over how specialized cells in the inner ear amplify sound in mammals appears to have been settled more in favor of bouncing cell bodies rather than vibrating, hair-like cilia. view more (2007-07-30)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
Scientists report study results from 'stealth' tsunami that killed 600 in Java last summer
Though categorized as magnitude 7.8, the earthquake could scarcely be felt by beachgoers that afternoon. A low tide and wind-driven waves disguised the signs of receding water, so when the tsunami struck, it caught even lifeguards by surprise. view more (2007-06-19)
Opening Up the Dark Side of the Universe
Physicists in the UK are ready to start construction of a major part of an advanced new experiment, designed to search for elusive gravitational waves. They are already part of two experiments: the UK/German GEO 600 project and the US LIGO experiment (Laser Interferometer Gravitational-Wave Observatory), both in their commissioning phases. By... view more... (2003-09-10)
Huge waves from one storm slam coasts some 6000 km apart
Huge waves that struck Reunion Island and coastlines across Indonesia earlier this month all originated from the same storm that occurred south of Cape Town, South Africa, and were tracked across the entire Indian Ocean for some 10 000 kilometres over a nine-day period by ESA's Envisat satellite. view more (2007-05-31)
Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and vice-versa. view more (2008-02-27)
Large earthquakes may broadcast warnings, but is anyone tuning in to listen?
Like geological ninjas, earthquakes can strike without warning. But there may be a way to detect the footfalls of large earthquakes before they strike, alerting their potential victims a week or more in advance. A Stanford professor thinks a method to provide just such warnings may have been buried in the scientific literature for over 40 years. view more (2007-12-13)
LLNL research reveals how blast waves may cause human brain injury even without direct head impacts
New research on the effects of blast waves could lead to an enhanced understanding of head injuries and improved military helmet design. view more (2009-08-27)
Tycho's Remnant Provides Shocking Evidence for Cosmic Rays
Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. view more (2005-09-23)
Next generation cloaking device demonstrated
A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers has produced a new type of cloaking device, which is significantly more sophisticated at... view more...
