A "slurp" says more than ten beeps
Natural warning sounds may be the future in airplanes and perhaps in cars as well. A "slurp" when fuel is low works better than a monotonous beeping sound. In a dissertation at The Royal Institute of Technology (KTH) in Sweden, Pernilla Ulfvengren has studied how warning sounds function,... view more (2003-12-18)

Study examines association between type of genetic characteristics and cancer
Persons with a certain type of homozygosity (having two identical copies of the same gene, one inherited from each parent), may have a greater predisposition to cancer, according to a study in the March 26 issue of JAMA.   view more (2008-03-26)

US satellite protection scheme could affect global communications
A proposed US system to protect satellites from solar storms or high-altitude nuclear detonations could cause side-effects that lead to radio communication blackouts, according to new research.   view more (2006-08-15)

Hair-sized lens helps look in blood vessels
A tiny measurement system that incorporates a lens as thick as two human hairs has been developed by researchers to investigate the force exerted on the wall of an artery as blood whooshes past. In a research paper published today in the Institute of Physics publication Journal of Micromechanics... view more (2002-03-20)

New Technology Could Transform Every Train into A High Speed Cracked Rail Detector
Researchers in the University of Warwick's Department of Physics have developed a novel non-contact method of using ultrasound to detect and measure cracks and flaws in rail track - particularly gauge corner cracking - that has the potential to simply be attached to a normal passenger or freight... view more (2004-07-05)

Diamonds key to a sparkling listening experience
Music lovers could be in for the ultimate listening experience, thanks to a new range of speakers containing parts made of diamond, writes Marina Murphy in the Chemistry & Industry magazine. The unique properties of diamond make the speakers less susceptible to distortion and thus provide a... view more (2005-02-18)

It whistles; change in pitch tells all in this new sonic gas analyzer
Penn State researchers have developed a prototype sonic gas analyzer that automatically and continuously tracks the concentration of a gas in an air/gas mixture based on changes in pitch.   view more (2005-10-20)

Prototype terahertz imager promises biochem advances
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new imaging system that detects naturally occurring terahertz radiation with unprecedented sensitivity and resolution.   view more (2008-04-16)

Chalmers first with integrated receiver for high frequency applications
As the first research group in the world, researchers at Chalmers have succeeded in combining a receiver for high frequencies with an antenna on a small chip.   view more (2007-11-29)

Chips for future multimedia radio systems
Millions of people surf the Internet, and their number is constantly increasing. But users regularly have to contend with bottlenecks when trying to access the net, or long periods of waiting while downloading sophisticated multimedia applications, such as video sequences for home learning. Radio... view more (1999-09-03)

No link between high blood pressure and headaches
Severe headaches are not a sign of high blood pressure, as is commonly thought, finds research in the Journal of Neurology Neurosurgery and Psychiatry. If anything, high blood pressure seems to reduce the risk of these headaches, the study shows.   view more (2002-03-21)

Research uncovers the social dynamics of yellow jackets
Michael Goodisman could be called the Maury Povich of the yellow jacket world. In his laboratory, Goodisman determines the paternity of yellow jackets to study family dynamics within a colony. Even though only one family lives within a colony, each yellow jacket queen mates with several males,... view more (2008-02-19)

Circuit board materials may like it hot (or not)
Electrical circuits may act differently in Arizona than they do in Alaska—potentially affecting the performance of computers and other electronics. A new technique identifies and quantifies an important cause of this temperature sensitivity.   view more (2006-06-09)

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... view more (2003-07-01)

Boston university researchers develop new model of ice volume change based on Earth's orbit
Through dated geological records scientists have known for decades that variations in the Earth's orbit around the sun — subtle changes in the distance between the two — control ice ages.   view more (2006-06-23)

Sound investment: A new mathematical method provides a better way to analyze noise
Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound.   view more (2006-07-27)

Mysterious energy burst stuns astronomers
In a shock finding, astronomers using CSIRO's Parkes telescope have detected a huge burst of radio energy from the distant universe that could open up a new field in astrophysics.   view more (2007-09-28)

UK Childhood Blindness More Common Than Previously Thought (p 1359)
Increased ethnic diversity and greater survival of low-birthweight babies is contributing to a higher proportion of children becoming visually impaired or blind, according to authors of a UK study in this week's issue of THE LANCET. The study also highlights how childhood visual impairment is... view more (2003-10-22)

Link between a sleep-related breathing disorder and increased heart rate variability
A sleep-related breathing disorder, common in heart failure, increases one's heart rate variability. Further, central sleep apnea (CSA) and obstructive sleep apnea (OSA) produce different patterns of heart rate variability, which are likely to reflect the different pathophysiological mechanisms... view more (2007-11-01)

Geologists Discover New Way of Estimating Size and Frequency of Meteorite Impacts
Scientists have developed a new way of determining the size and frequency of meteorites that have collided with Earth.   view more (2008-04-14)

Radio Frequency tagging for preventing theft and tracking stocks
Tagging individual items with barely noticeable disposable electronic circuits that can be detected with a radio wave scanner is becoming increasingly common, with over 4 billion circuits sold last year. There are many applications where tags are currently in use. Manufacturers and distributors use... view more (2003-06-03)

Genes and the environment contribute differently to drinking among young adolescents
A 2001/2002 report by the World Health Organization found that, among young people in western countries who began drinking before 16 years of age, the average age of initiation was 12 years of age.   view more (2008-05-06)

Cloud radar -- predicting the weather more accurately
The weather. It's the one topic of conversation that unites Britain - umbrella or sun cream? Now scientists at the Science and Technology Facilities Council have developed a system that measures the individual layers of cloud above us which will make answering the all-important weather questions... view more (2008-09-25)

Researchers bridge the 'terahertz gap' with new tunable metamaterial
A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered by a team of researchers from Boston College, Los Alamos National Laboratory and Boston University.   view more (2008-04-16)

Weather, waves and wireless: Super strength signalling
A new study from the University of Leicester has discovered a particular window of time when mobile signals and radio waves are 'super strength' - allowing them to be clearer and travel greater distances, potentially interfering with other systems.   view more (2008-05-19)
