NASA Says a Coming Wave of Extreme Solar Activity Could Threaten Technology Underpinning Human Civilization


Earth and space are about to come into contact in a way that's new to human history. To make preparations, authorities in Washington DC are holding a meeting: The Space Weather Enterprise Forum at the National Press Club on June 8th.

Many technologies of the 21st century are vulnerable to solar storms. Richard Fisher, head of NASA's Heliophysics Division, explains what it's all about:

"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has developed an unprecedented sensitivity to solar storms. The intersection of these two issues is what we're getting together to discuss".'

American Military Creating an Environmental Disaster in Afghan Countryside


The American military presence in Afghanistan consists of fleets of aircraft, helicopters, armored vehicles, weapons, equipment, troops and facilities. Since 2001, they have generated millions of kilograms of hazardous, toxic and radioactive wastes. The Kabul Press asks the simple question:

"What have the Americans done with all that waste?"

The answer is chilling in that virtually all of it appears to have been buried, burned or secretly disposed of into the air, soil, groundwater and surface waters of Afghanistan. While the Americans may begin to withdraw next year, the toxic chemicals they leave behind will continue to pollute for centuries. Any abandoned radioactive waste may stain the Afghan countryside for thousands of years. Afghanistan has been described in the past as the graveyard of foreign armies. Today, Afghanistan has a different title:

"Afghanistan is the toxic dumping ground for foreign armies".'

Radiation Therapy Harms the Brain, Causing Memory and Attention Problems

Radiation therapy for the treatment of brain tumors may lead to cognitive decline later in life, according to a study conducted by researchers from VU University Medical Centre in Amsterdam, Netherlands, and published in The Lancet Neurology.

Scientists have known for some time that radiation therapy can damage healthy brain tissue, but prior research found no immediate negative effects from the treatment. In the new study, researchers conducted brain function tests on 65 patients who had undergone treatment for low-grade glioma 12 years previously.'

Toxic link: the WHO and the IAEA

Fifty years ago, on 28 May 1959, the World Health Organisation's assembly voted into force an obscure but important agreement with the International Atomic Energy Agency – the United Nations "Atoms for Peace" organisation, founded just two years before in 1957. The effect of this agreement has been to give the IAEA an effective veto on any actions by the WHO that relate in any way to nuclear power – and so prevent the WHO from playing its proper role in investigating and warning of the dangers of nuclear radiation on human health.

Magnetic Shield For Spacefarers

Future astronauts could benefit from a magnetic "umbrella" that deflects harmful space radiation around their crew capsule, scientists say.
The super-fast charged particles that stream away from the Sun pose a significant threat to any long-duration mission, such as to the Moon or Mars.
But the research team says a spaceship equipped with a magnetic field generator could protect its occupants.
Lab tests are reported in the journal Plasma Physics and Controlled Fusion.
The approach mimics the protective field that envelops the Earth, known as the magnetosphere.

Mobile phone use 'raises children's risk of brain cancer fivefold'


Children and teenagers are five times more likely to get brain cancer if they use mobile phones, startling new research indicates.
The study, experts say, raises fears that today's young people may suffer an "epidemic" of the disease in later life. At least nine out of 10 British 16-year-olds have their own handset, as do more than 40 per cent of primary schoolchildren.
Yet investigating dangers to the young has been omitted from a massive £3.1m British investigation of the risks of cancer from using mobile phones, launched this year, even though the official Mobile Telecommunications and Health Research (MTHR) Programme – which is conducting it – admits that the issue is of the "highest priority".
Despite recommendations of an official report that the use of mobiles by children should be "minimised", the Government has done almost nothing to discourage it.
