Latest Electrical phenomena Stories
Astronauts aboard the International Space Station recently filmed what is among the most spectacular night imagery ever taken from space of the United States.
The heart’s inner workings are mysterious, perhaps even more so with a new finding. Engineers at the University of Washington have discovered an electrical property in arteries not seen before in mammalian tissues.
Graphene, the ultra-durable carbon material that holds promise for a range of applications, has yet another trick up its single-atom-thick sleeve.
TAU researchers predict "sprites" in the atmospheres of Jupiter, Saturn, and Venus.
For the first time, engineering researchers have been able to watch in real time the nanoscale process of a ferroelectric memory bit switching between the 0 and 1 states.
Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin-Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.
Part of human fascination with space is the chance to look back at our own planet from afar. The unique vantage from the International Space Station affords a vista both breathtaking and scientifically illuminating.
A team at Princeton University has developed a four-inch transparent magic carpet.
Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices.
Crystals and ceramics pale when compared to a material researchers at Oak Ridge National Laboratory discovered that has 10 times their piezoelectric effect, making it suitable for perhaps hundreds of everyday uses.
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...
