U.S. government scientists say they have created a method of measuring the intrinsic conducting properties of ferroelectric materials. The researchers at the Center for Nanophase Materials Sciences at the U.S. Department of Energy's Oak Ridge National Laboratory in Tennessee say their achievement could lead to much smaller, faster and more powerful electronic devices. For years, the challenge has been to develop a nanoscale material that can act as a switch to store binary information, Peter...

Experts say 2009 already has been proved a dangerous year for lightning strikes in the United States and warn the worst may be yet to come. National Weather Service lightning expert John Jensenius said 11 people have been killed in the United States by lighning strikes just this month as the particularly dangerous summer months get under way, ABC News reported Monday. Last year was an exceptionally good year for not having fatalities. This year is starting out as an exceptionally bad year,...

Most people know to unplug computers to prevent lightning damage but some are injured by lightning using hardwired video games, a U.S. researcher says. Dr. Mary Ann Cooper, director of the lightning injury research program at the University of Illinois at Chicago, notes an increasing number of people injured indoors using Play Stations and other such video games. Cell phones, iPods and other wireless devices do not attract lightning but they may distract people from paying attention to the...

Electronic devices of the future could be smaller, faster, more powerful and consume less energy because of a discovery by researchers at the Department of Energy's Oak Ridge National Laboratory.The key to the finding, published in Science, involves a method to measure intrinsic conducting properties of ferroelectric materials, which for decades have held tremendous promise but have eluded experimental proof. Now, however, ORNL Wigner Fellow Peter Maksymovych and co-authors Stephen Jesse, Art...

U.S. scientists are using high-energy particles from space in an attempt to solve one of nature's mysteries -- how thunderstorms create lightning. Florida Institute of Technology researchers Joseph Dwyer and Hamid Rassoul, with Martin Uman from the University of Florida, have developed a technique to remotely measure thunderstorm electrical fields on the ground. They said by measuring small radio pulses made by cosmic-rays passing through the storms, they might be able to reconstruct the...

University of Leicester researchers have taken a step forward in helping to create a defence for earth's technologies "“from the constant threat of space weather.They have implemented a "double pulse" radar-operating mode on two radars, which form part of a global network of ground based coherent scatter radars called SuperDARN (Super Dual Auroral Radar Network).These radars allow observations of space weather, which can have devastating impacts for technologies on earth.James...

Experts say passenger jets are hit by lightning every 1,000 hours (on average twice a year) and the risk from the bolts of electricity continues to be an increasing problem, AFP reported. However, after the disappearance of an Air France jet in the Atlantic with the feared loss of 228 lives, technical experts say lightning alone could not have caused it to crash into the ocean. The A300-200 jet was likely hit by lightning as it passed through a violent storm on the flight from Rio de Janeiro...

Trying to find how thunderstorms create lightning Florida Institute of Technology researchers are trying to solve one of the great mysteries in nature: how thunderstorms make lightning. Because, in principle, lightning is a big spark it should behave like other sparks"”like the ones created when we touch a door knob on a dry day. Scientists have accumulated evidence, however, that lightning sometimes behaves in very un-spark-like ways. Lightning can start in regions of thunderstorms...

U.S. researchers say they have developed a technique using a silicon crystal as a type of nanoscale vice to squeeze another crystal into a more useful shape. The scientists led by Professor Darrell Schlom of Cornell University and Joseph Woicik of the National Institute of Standards and Technology said their accomplishment might lead to development of a new class of electronic devices that remember their last state even after power is turned off. Computers that could switch on instantly...

A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. Computers that could switch on instantly without the time-consuming process of "booting" an operating system is just one of the possibilities, according to a new paper by a team of researchers spanning four universities, two federal...

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
