Killer Electrons In Space Are Now Less Mysterious

A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding. 'Killer' electrons are highly energetic, negatively charged particles found in near-Earth space. They can critically, and even permanently, damage satellites in orbit, including telecommunication satellites, and pose a hazard to astronauts.

Several theories have been formulated in the past to explain the origin of killer electrons, and many uncoordinated observations have already been performed. Recently, scientists got a boost in their understanding of this hazardous phenomenon. This was possible thanks to a unique set of data, collected simultaneously, by a global armada of ground and space observatories during the recovery phase of a large geomagnetic storm.

Surprise: U.S. Electronic Voting Systems Fail Security Tests!

Electronic voting systems are yet an other tool being used by pathocrats to implement total control over everyone and everything. If you needed any more proof then here it is.

The night watchman

Most nights, as the southern hemisphere sleeps, Rob McNaught is awake and on guard. He's part of an international team of astronomers scanning the skies for Near Earth Objects (NEOs), such as asteroids and comets, that could pose a threat to our planet. Scientists believe that large objects colliding with the Earth in the past may have had cataclysmic effects, wreaking destruction at the point of impact, altering global climate patterns and causing mass extinctions. Working with colleagues at the University of Arizona, McNaught has discovered or co-discovered more than 30 comets and thousands of asteroids from his base at Siding Spring in outback New South Wales. So far none of the NEOs appear to be an immediate threat. But very rarely, one of these space travellers does pass close to our planet with spectacular results.

Comment: For more information, read the SOTT focus article: Forget About Global Warming: We're One Step From Extinction! to understand what is really coming our way. Preparations could be underway to prepare for the future, yet, the Pathocrats ruling the planet continue to funnel resources into widespread genocide. Rest assured that their own contingency plans are in place, however.

'Bizarre' new bacterium ID'd at Yellowstone

The wonderland of Yellowstone National Park has yielded a new marvel - an unusual bacterium that converts light to energy.

The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth.

"This thing was just bizarre," David M. Ward, a professor of microbial studies at Montana State University, said of the bacterium.

Heart and Soul are located in Cassiopeia

Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805 and visible above on the right, has a shape reminiscent of a classical heart symbol.

Cheap microphones listen for landmines

Landmines lurking in former combat zones could be uncovered just by listening for them.

A major obstacle to clearing mines in poorer countries is the cost. In one method, mine clearers beam a low-frequency sound wave into the ground - which gently vibrates any buried mines - along with a radar beam. When the radar beam bounces off any vibrating mines it is reflected back at a different frequency. The problem is that radar sensors cost hundreds of dollars.

Retina Minibrain: The Movies in Our Eyes

The retina processes information much more than anyone has ever imagined, sending a dozen different movies to the brain

At early stages of visual processing the world is divided into neurons that signal increases, and others that signal decreases in contrast at each point in visual space. Subsequent to that division in activity, these two signal paths begin to interact, and they inhibit each other at every single stage of visual processing from retina to visual cortex. This fascinating "crossover inhibition" takes many forms....feedback, feed forward, feed across. It also serves many important signal processing functions including common mode rejection, non-linearity correction, drift compensation, and noise reduction. Our lab is studying the neural circuitry that mediates this crossover interaction in an attempt to learn the secrets embodied in this treasure trove of highly sophisticated biological technology.

Taiwanese star-gazer discovers comet

It was so faint amid the star-freckled blackness that professional star-gazer Lin Chi-sheng missed it as he photographed the heavens from Lulin Observatory, Nantou County, earlier this month.

Luckily, Lin's camera, recording time-lapse images of space through the observatory's telescope, didn't miss it -- a mighty chunk of ice and rock "a few kilometers" in diameter and hurtling toward Earth: "Asteroid C/2007-N3."

US: Wild weather forces farmers to adapt

Around the world, extreme climatic conditions are forcing farmers to rethink current cropping system strategies. To maximize crop production in the face of variable temperatures and precipitation, scientists say farmers may want to adopt a system in which crop sequencing decisions are based upon weather patterns and management goals each year. However, before making the change to a more adaptable cropping systems strategy, researchers say it's important to understand how short-term crop sequencing decisions affect key agronomic and environmental attributes.

From 2002-2005, a team of researchers at the USDA-ARS Northern Great Plains Research Laboratory in Mandan, North Dakota investigated crop sequencing effects of 10 crops in a region known for its variable climate. The researchers report their findings as a series of six papers in the July-August 2007 issue of Agronomy Journal. The results from the study were originally presented at the 2005 ASA-CSSA-SSSA annual meeting.

Origin And Evolution Of Saturn Rings Explained

Russian scientist suggests a hypothesis, allowing satisfying description for mechanisms of origin and evolution of Saturn rings and, possibly, other circular structures of the Solar system.

Saturn rings could have appeared after "switching on" of giant planet's magnetic field as a result of interaction between superconducting particles of the protoplanetary cloud and magnetic field.
