The South Atlantic Anomaly, more commonly known as SAA is an occurrence that takes place due to something known as the Van Allen Radiation Belts. These Van Allen radiation belts are responsible for trapping radioactive particles near the coast of Brazil, which creates the SAA phenomenon.

However, one good thing about the South Atlantic Anomaly caused due to the naturally occurring Van Allen radiation belts is that, they do not cause any harm to humans and their bodies. The main effects of the SAA phenomenon are exhibited only in air crafts and air vessels which take that route while flying.

Comment: Despite the article's claim that Van Allen radiation belts do not cause any harm to humans and their bodies (and there is no way of knowing it for sure), there is a high chance that these belts carry serious implications for the Earth's climate.

From Chemtrails? Contrails? Strange Skies by Laura Knight-Jadczyk:
Comment: Regarding these layers of electromagnetism surrounding the Earth, in 1958 some things were done that may very well have a strong bearing on the conditions of our planet in the present day. I would like for you to think about this in respect of climate change, so-called "chem-trails" and HAARP.
"Between August and September of 1958, the US Navy exploded three fission type nuclear bombs 480 km above the South Atlantic Ocean, in the part of the lower Van Allen Belt closest to the earth's surface. In addition, two hydrogen bombs were detonated 160 km over Johnston Island in the Pacific. The military called this "the biggest scientific experiment ever undertaken." It was designed by the US Department of Defense and the US Atomic Energy Commission, under the code name Project Argus. The purpose appears to be to assess the impact of high altitude nuclear explosions on radio transmission and radar operations because of the electromagnetic pulse (EMP), and to increase understanding of the geomagnetic field and the behavior of the charged particles in it. This gigantic experiment created new (inner) magnetic radiation belts encompassing almost the whole earth, and injected sufficient electrons and other energetic particles into the ionosphere to cause world wide effects. The electrons traveled back and forth along magnetic force lines, causing an artificial "aurora" when striking the atmosphere near the North Pole. This was reported only much later, on August 13-20th of 1961 in Keesings Historisch Archief (K.H.A.). The report said that the US Military planned to create a "telecommunications shield in the ionosphere at 3,000 km height, by bringing into orbit 350,000 million copper needles, each 2-4 cm long [total weight 16 kg], forming a belt 10 km thick and 40 km wide, the needles spaced about 100 m apart." This was designed to replace the ionosphere "because telecommunications are impaired by magnetic storms and solar flares." The US planned to add to the number of copper needles if the experiment proved to be successful. This plan was strongly opposed by the International Union of Astronomers."
Then:
On July 9th, 1962, the US began a further series of experiments with the ionosphere. From their description: "one kiloton device, at a height of 60 km and one megaton and one multi-megaton, at several hundred kilometers height". (K.H.A., 29 June 1962).

These tests seriously disturbed the lower Van Allen Belt, substantially altering its shape and intensity. "In this experiment the inner Van Allen Belt will be practically destroyed for a period of time; particles from the Belt will be transported to the atmosphere. It is anticipated that the earth's magnetic field will be disturbed over long distances for several hours, preventing radio communication. The explosion in the inner radiation belt will create an artificial dome of polar light that will be visible from Los Angeles". (K.H.A. 11 May 1962).

This was the experiment which called forth the strong protest of the Queen's Astronomer, Sir Martin Ryle in the UK. On the 19th of July... NASA announced that as a consequence of the high altitude nuclear test of July 9th, a new radiation belt had been formed, stretching from a height of about 400 km to 1600 km; it can be seen as a temporary extension of the lower Van Allen Belt" (K.H.A. 5 August 1962).

"... Starfish made a much wider belt [than Project Argus] that extends from low altitude out past L=3 [i.e. three earth radiuses or about 13,000 km above the surface of the earth]."Later in 1962, the USSR undertook similar planetary experiments, creating three new radiation belts between 7,000 and 13,000 km above the earth. According to the Encyclopedia, the electron fluxes in the lower Van Allen Belt have changed markedly since the 1962 high-altitude nuclear explosions by the US and USSR, never returning to their former state. According to American scientists, it could take many hundreds of years for the Van Allen Belts to destabilize at their normal levels."
Keep in mind now that, while they are out there blowing up our atmosphere, they want to blame Global Warming on the masses of regular people!

The virus killed a third of the monkeys at the colony, but only seemed to cause cold-like symptoms in humans.
An outbreak of a monkey-killing cold virus is the first example of an adenovirus that can infect both monkeys and humans.

Since they were discovered in the 1950s, researchers have thought each adenovirus strain could infect only one species of animal. One species of adenovirus might be able to infect only a hamster while another might infect only a cat. This is the first example of an adenovirus infecting two different types of animals, in this case, titi monkeys and lab-worker humans.

"Now adenoviruses can be added to the list of pathogens that have the ability to cross species," study researcher Charles Chiu, director of the viral diagnostics center at the University of California, San Francisco, said in a statement.

Astronomers Find Spinning Neutron Star Tied to Mysterious Tail

A mysterious long X-ray tail spanning more than 4 light years across may be stretching away from a spinning neutron star, or pulsar, according to astronomers who discovered the event using NASA's Chandra X-ray Observatory.

The pulsar, named PSR J0357+3205, is located about 1,600 light years from Earth and was originally discovered by the Fermi Gamma Ray Space Telescope in 2009.

Astronomers calculate that the pulsar is about half a million years old, which makes it roughly middle-aged for this type of object.

Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation, which can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name.

Neutron star, as its name implies composed almost entirely of neutrons, is a type of stellar remnant resulting from the gravitational collapse of a massive star during a supernova event.

A study has found that large, marine-calving glaciers have the ability not only to shrink rapidly in response to global warming, but to grow at a remarkable pace during periods of global cooling.

The finding, by University at Buffalo geologists working in Greenland, stems from new research on Jakobshavn Isbrae, a tongue of ice extending out to sea from Greenland's west coast.

Through an analysis of adjacent lake sediments and plant fossils, the UB team determined that the glacier, which retreated about 40 kilometres inland between 1850 and 2010, expanded outward at a similar pace about 200 years ago, during a time of cooler temperatures known as the Little Ice Age.

"We know that Jakobshavn Isbrae has retreated at this incredible rate in recent years, and our study suggests that it advanced that fast, also," said Jason Briner, the associate professor of geology who led the research.

Comment: Now, imagine a sudden drop in global temperatures, due to external and cosmic related influences, then consider the following excerpts from Superluminal Communications:

February 22, 1997:
A: ...One change to occur in 21st Century is sudden glacial rebound, over Eurasia first, then North America. Ice ages develop much, much, much faster than thought.
March 18, 2000:
Q: You also made a remark once that ice ages occur much, much faster than people ever thought...
A: Yes.
Q: Do we need to invest in some mukluks and snowshoes?
A: ??
Q: Well, what I am trying to get at is: should we start stockpiling firewood?
A: Maybe.
Q: So, it could be that fast?
A: Oh yes, and faster when in response to global" warming."
Q: When you put "warming" in quotes, you obviously mean warming in more than just an ordinary sense? Is that correct?
A: And/or not really "warm."

"The skies over the Spanish island of La Palma offer many beauties, but on July 4th I witnessed something unusual: a ghostly green laser beam crossing the Milky Way," reports Jan Hattenbach from the Canary Islands. "I have learned that it was part of an experiment in quantum communication." Scroll past the laser for more information:

"Rupert Ursin of the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences explained to me that the laser was part of an inter-island quantum-cryptography experiment," says Hattenbach. "Physicists send entangled UV-photons from the Roque de los Muchachos observatory (ORM) on La Palma to the European Space Agency's Optical Ground Station 144 km away on the island of Tenerife. The goal is to demonstrate the feasibility of quantum communication over very long distances in space--e.g., to the International Space Station or other satellites.

A bioengineered tooth engrafted into the lower jaw of a mouse
A team of Japanese scientists have created complete tooth units by using mouse stem cells and successfully transplanted them into mice.

The tooth units, which also contain connective fibers and bones, were attached successfully to the lower jaw bones, and helped the rats to chew normally, researchers wrote in PLoS One.

As the first step, researchers isolated two types of stem cells from the molar teeth of mice and grew them in the laboratory.

The cells formed a tiny "tooth bud" within five days, which were then placed in a mold. The primary structures were then placed inside the body of the mouse until a complete tooth unit was formed.

"The bioengineered teeth were fully functional ... there was no trouble (with) biting and eating food after transplantation," wrote Masamitsu Oshima from the Research Institute for Science and Technology, Tokyo University of Science.

Company that built the first internet node hired

The company which built the first ever internet nodes back in the 1960s - and which gave the world the "@" symbol in email, among other things - has been hired by the US intelligence community to work on technology which could mimic "the brain's ability to make sense of large amounts of haphazard, partial information".

Back in the late 1960s, Boston-based BBN technologies was hired by the US military Advanced Research Projects Agency (later renamed DARPA) to develop the first nodes of the ARPAnet, which later became the internet we all know and love. DARPA's various successes for the military over the decades since have inspired the CIA and allied US intelligence agencies to start up their own version of the famous bureau, dubbed the Intelligence Advanced Research projects Agency (IARPA).

How to Design a Trial to Ensure You Don't Get the Result You Don't Want

Earlier this month I wrote a post that focused on a trial involving the cholesterol-reducing drug ezetimibe. Ezetimibe works in a different way to statins (the most commonly prescribed cholesterol-reducing medication). While statins block cholesterol's production in the liver, ezetimibe block its absorption from the gut.

When you add ezetimibe to a statin (there's a medication called Vytorin that includes both), you can surely get a stunning reduction in cholesterol numbers. The problem is, as I've been at pains to point out before, the effect drugs (or anything else) have on cholesterol is irrelevant - it's the impact they have on health, that counts. Trust me when I tell you if can lodge this fact in your head, you'll be way ahead of many doctors and researchers in your thinking.

Sun evaporates comet
© NASA / SDO / AIAThe Solar Dynamics Observatory AIA imager (observing in extreme ultraviolet light) actually spotted a sun-grazing comet as it disintegrated over about a 15-minute period on July 6, something never observed before. The angle of the comet's orbit brought it across the front half of the sun. Given the intense heat and radiation, the comet simply evaporated away. The comet was probably a member of the Kreutz sun-grazer family.
Satellite witnesses a 'sun-grazer' hit heat and disintegrate in 15 minutes

The death of a comet that plunged into the sun was captured on camera this month for the first time in history, scientists say.

The comet met its fiery demise on July 6 when it zoomed in from behind the sun and melted into oblivion as it crashed into the star. NASA's Solar Dynamics Observatory (SDO), a satellite orbiting Earth that studies the sun, witnessed the comet's death-blow.

One of the SDO spacecraft's high-definition imagers "actually spotted a sun-grazing comet as it disintegrated over about a 15-minute period July 6, 2011, something never observed before," SDO officials said.

Comets have been spotted near the sun before, but last week's object was the first to be observed in real-time as it disappeared.

"Given the intense heat and radiation, the comet simply evaporated away completely," SDO officials said.

Mouse experiment
Everyone has been tweeting this new paper, and I have to say, it's a doozy. I don't recommend that many papers, as most are fairly painful to read (though many papers are full of interesting facts, they don't teach scientists how to write), but if you can get your hands on this one, please do so.

The Intestinal Microbiota Affect Central Levels of Brain-Derived Neurotropic Factor and Behavior in Mice

Let's dive in. Ooh, I like the first part:
The intestinal microbiota is a vast ecosystem that shapes a wide variety of host functions, both within and outside the gastrointestinal tract.
Y'all may recall my previous article in which we have evidence that your commensal beasties, which make up 90% of your cells, also control a mouse's brain (and possibly yours.) And something like this paper and this experimental design excite me more than the endocannabinoid/rat paper I wrote about yesterday. I don't doubt that we probably have endocannabinoid receptors for corn oil (which may be activated by all kinds of fats) in our guts, or ones for sweets in our mouths, I'm just not sure what it means when isolated in that way via the sham-feeding and with creepy rat chow liquid diets that immediately drain out and dribble onto the rat cage in a gross gut slurry. However, we do have to keep in mind that these are rodents who diverged from the family tree many many many millions of years ago...
