GM Corn 'Has Polluted Rivers Across the United States'

An insecticide used in genetically modified (GM) crops grown extensively in the United States and other parts of the world has leached into the water of the surrounding environment.

The insecticide is the product of a bacterial gene inserted into GM maize and other cereal crops to protect them against insects such as the European corn borer beetle. Scientists have detected the insecticide in a significant number of streams draining the great corn belt of the American mid-West.

The researchers detected the bacterial protein in the plant detritus that was washed off the corn fields into streams up to 500 metres away. They are not yet able to determine how significant this is in terms of the risk to either human health or the wider environment.

Drilling into a Volcano Aims to Help Predict Possible Catastrophe

Drilling into an active volcanic doesn't sound like the safest idea, but a plan to do so along a volcano near Naples, Italy, could help protect the city from a potentially catastrophic eruption.

Geologists will drill into the volcanic formation, called Campi Flegrei, early next month. The volcano, part of a larger volcanic arc that includes Mount Vesuvius, last erupted in 1538. The ground around the volcano, however, has been swelling for the past 40 years, stoking fears of an eruption that would threaten the roughly 1 million residents of Naples.

"The role of deep drilling at this area is then crucial," according to the drilling project description by the International Continental Scientific Drill Program (ICDP), which is planning the drilling study.

The drilling will let scientists pull out rocks that will allow them to trace the volcano's evolution, and predict its future.

Nuclear Weapons: 20 Facts They Don't Want You to Think About

Politicians and Their Armageddon Machines

Nuclear arsenals: who wants them? - A coterie of politicians.

Why do they want them? - For the illusion of power and to feed their egos.

How do they keep them? - By fostering a culture of fear.

How do they do that? - By positing a Threatening and Unknown Future.

There are 5 primary nuclear weapons states (and four others from proliferation). The politicians of these 5 nuclear states put the future of the citizens of all the other 187 states of the UN at risk as well as their own citizens because of their insistence in keeping their nuclear arsenals.

In no case have the citizens been asked if they want these arsenals.

The reason these politicians want these Armageddon weapons is because they believe it gives them stature and power; makes them players; gets their feet under the top table. For this perceived personal benefit they are prepared to put the survival of the human race at risk.

Nuclear arsenals are the ruthless tools of power-fixated individuals.

In order to keep their arsenals, these individuals must keep the citizens in ignorance. We have a vague dread of these things and what they can do. Humanity has a residual group memory of the unspeakable suffering of Hiroshima and Nagasaki. But this is very scary. We don't want to think about it. And that suits the power junkies just fine. Ignorance is power - for the junkies - but not the citizens.

Genetically Altered Salmon? It Doesn't Stop There

We've always played with our food - even before we knew about genes or how to change them.

For thousands of years, humans have practiced selective breeding - pairing the beefiest bull with the healthiest heifers to start a new herd. That concept was refined to develop plant hybridization and artificial insemination. Today we've got tastier corn on sturdier stalks, bigger turkeys and meatier cattle.

Now comes an Atlantic salmon that is genetically engineered to grow twice as fast as a regular salmon. If U.S. regulators approve it, the fish would be the first such scientifically altered animal to reach the dinner plate.

Scientists have already determined that it's safe to eat. They are weighing other factors, including environmental risks, after two days of intense hearings.

Are Tornadoes Increasing?

Few sights on Earth are as awe-inspiring (or terrifying) as that of a tornado spindling down from a storm-choked sky. So we feed our obsession. We flood the Internet with twister footage and headlines about peculiar vortices and rampaging storms.

It all leads to an inevitable question: Is tornadic activity increasing?

"There's no evidence that it is," says Joshua Wurman, president of the Center for Severe Weather Research. "If you look at the frequency of tornado reports in the U.S., they're going up every decade, but there's pretty good evidence that it's due to improved reporting efficiency."

Scientists call this a reporting effect, meaning that reports of a phenomenon increase but actual occurrences do not. Yes, it might seem like more trees are falling in the forest, but it's only because more people are there to hear them.

Northern Lights Becoming Rarer, Researchers Warn

The Northern Lights have petered out during the second half of the decade, becoming rarer than at any other time in more than a century, according to meteorologists.

The Aurora Borealis generally follows an 11-year "solar cycle" in which the frequency of the phenomena rises to a maximum and then tapers off into a minimum and then repeats the cycle.

According to researched at the Finnish Meteorological Institute, however, the solar minimum was officially in 2008, but has been "going on and on and on".

Noora Partamies, a researcher, said: "Only in the past half a year have we seen more activity, but we don't really know whether we're coming out of this minimum."

The Northern Lights, a blaze of colored patterns in the northern skies, are triggered by solar winds crashing into the earth and being drawn to the magnetic poles, wreaking havoc on electrons in the parts of the atmosphere known as the ionosphere and magnetosphere.

Drenched Mexico Hillside Collapses; At Least 7 Die

Oaxaca, Mexico - A hillside collapsed on hundreds of sleeping residents Tuesday in a rural Mexican community drenched for days by two major storms, killing at least seven and leaving at least 100 missing, disaster officials said.

The death toll could rise much higher in Santa Maria Tlahuitoltepec, a town about 130 miles (220 kilometers) southeast of Mexico City. Oaxaca state Civil Protection operations coordinator Luis Marin said 100 people were confirmed missing, but Oaxaca Gov. Ulises Ruiz told the Televisa television network 500 to 1,000 people could be buried.

At least 100 homes were buried, and residents who made it out have had no success in digging out their neighbors, said Donato Vargas, an official in Santa Maria de Tlahuitoltepec reached by a satellite telephone.

"We have been using a backhoe but there is a lot of mud. We can't even see the homes, we can't hear shouts, we can't hear anything," he said.

Hundreds Feared Dead After Landslide Buries Mexico Town

'We can't even see the homes,' survivor says; 8,000 people impacted, more slides feared

Hundreds of people were buried in their homes early Tuesday after a rain-soaked mountainside gave way in southwestern Mexico, officials said.

Donato Vargas, an official in Santa Maria Tlahuitoltepec reached by phone, said 500 people were missing and that 300 homes were buried after the slide around 4 a.m. local time.

"We were all sleeping and all I heard was a loud noise and when I left the house I saw that the hill had fallen," Vargas said.

"It has been difficult informing authorities because the roads are very bad and there isn't a good signal for our phone," Vargas said shortly before the call dropped.

Reached by the news agency AFP, Vargas added that "we fear that those missing are buried inside their homes because we've already searched nearby areas."
