CT Scans Emit Massive Doses of Radiation, Promote Cancer

(NaturalNews) A British government report has called for tighter regulation of private clinics that offer full-body computed tomography (CT) scans, saying that such scans expose patients to a massive and cancer-promoting blast of radiation.

Many private clinics offer full-body CT scans to patients who want to search for early indicators of heart disease or cancer. In the United Kingdom, such scans typically cost between £500 and £2,000 ($1,000-$4,000).

The new report by the Committee on the Medical Aspects of Radiation strongly advises that private clinics end this practice, and says that the government needs to better regulate the practice.

Full-body CT scans expose patients to approximately 100 times the radiation of a standard chest X-ray. Any radiation exposure is known to increase the risk of cancer, in particular, radiation in high doses. The report says that for every 2,000 people getting a full-body CT scan twice per year, one can be expected to contract a fatal cancer.

The Microwave Scream Inside Your Skull

The U.S. military bankrolled early development of a non-lethal microwave weapon that creates sound inside your head. But in the end, the gadget may be just as likely to wind up in shopping malls as on battlefields, as I report in New Scientist.

The project is known as MEDUSA – a contrived acronym for Mob Excess Deterrent Using Silent Audio. And it should not be confused with the Long Range Acoustic Device and similar gadgets which simply project sound. This one uses the so-called “microwave auditory effect”: a beam of microwaves is turned into sound by the interaction with your head. Nobody else can hear it unless they are in the beam as well.

The effect has long been a laboratory curiosity, with no application. But, over the years, the military has been intrigued. The idea (dubbed “the telepathic ray gun”) was mentioned in a 1998 US Army study, which turned up in a recent Freedom of Information Act document dump. Five years later, the Navy decided to put some R&D dollars into the project. Now, as I note on the New Scientist website, Dr. Lev Sadovnik of the Sierra Nevada Corporation has provided more details.

There are health risks, he notes. But the biggest issue from the microwave weapon is not the radiation. It’s the risk of brain damage from the high-intensity shockwave created by the microwave pulse. Clearly, much more research is needed on this effect at the sort of power levels that Dr. Sadovnik is proposing. But if it does prove hazardous, that does not mean an end to weapons research in this area: a device that delivered a lethal shockwave inside the target’s skull might make an effective death ray.

MIT group makes low-cost dish to tap solar energy

Photo

Spencer Ahrens, a 23-year-old mechanical engineer, was on MIT’s campus last week, holding a wooden plank, surrounded by onlookers.

Slowly, he turned that wooden plank before a series of mirrors that had been placed inside an aluminum frame, until the wood caught fire.

That was quite a moment, recalled Matthew Ritter, one of the onlookers.

“Let’s just say it was a small combustion for wood materials, but a giant explosion of solar energy,” he said.

Ahrens, Ritter and the other people who helped create the solar-powered dish that harnessed the sunlight that eventually burned the wood say they’ve just created the world’s most cost-efficient solar power system.

They also say these dishes may revolutionize global energy production.

“You can stick these things wherever there is a piece of sunlight, and power a home or an industrial plant,” said Ahrens, who just received his master’s degree from MIT.

Since January, he’s been working with Ritter, an Olin College student; Micah Sze, a recent graduate of MIT’s Sloan School of Management; University of California-Berkeley graduate and Broad Institute engineer Eva Markiewicz and MIT materials science student Anna Bershteyn.

Together, they built a 12-foot wide solar panel by piecing together lightweight aluminum tubes to make the frame. Inside, they arranged a series of mirrors and then attached a water-filled coil at the bottom of the frame.

When the frame is properly positioned, the mirrors will direct concentrated sunlight toward the coil.

As the water heats up, it is converted to steam, and that steam, the creators say, can be used to generate electricity to heat and cool homes and power machines.

They now say its design is so simple, it can be built and placed just about anywhere the sun shines.

“We made it by hand and transported the parts by car or by bike,” Ritter said.

The crew spent about $5,000 to build the dish, and according to MIT Sloan School of Management lecturer David Pelly, it is the cheapest way he’s seen to harness that much sun power.

“I’ve looked for years at a variety of solar approaches, and this is the cheapest I’ve seen,” he said.

Ahrens, Ritter and the others are now packing up and moving to California, where they plan to mass-produce the dishes, probably for less than it cost to build the first one.

Their new company is called RawSolar, and Ahrens said its possibilities are endless.

“The energy crisis affects so much of what we do,” Ahrens said. “It’s driving food prices and water problems and airline fares, and we are trying to work through these things in an environmentally and economically sustainable way.”

After all, he said, “Sunlight is free.”

Photographer Documents Secret Satellites — All 189 of Them


Artist Trevor Paglen’s time-exposure photographs show the streaks of light left by classified satellites.

BERKELEY, California — For most people, photographing something that isn’t there might be tough. Not so for Trevor Paglen.

His shots of 189 secret spy satellites are the subject of a new exhibit — despite the fact that, officially speaking, the satellites don’t exist. The Other Night Sky, on display at the University of California at Berkeley Art Museum through September 14, is only a small selection from the 1,500 astrophotographs Paglen has taken thus far.

In taking these photos, Paglen is trying to draw a metaphorical connection between modern government secrecy and the doctrine of the Catholic Church in Galileo’s time.

“What would it mean to find these secret moons in orbit around the earth in the same way that Galileo found these moons that shouldn’t exist in orbit around Jupiter?” Paglen says.

Satellites are just the latest in Paglen’s photography of supposedly nonexistent subjects. To date, he’s snapped haunting images of various military sites in the Nevada deserts, “torture taxis” (private planes that whisk people off to secret prisons without judicial oversight) and uniform patches from various top-secret military programs.

While all of Paglen’s projects are the result of meticulous research, he’s also the first to admit that his photos aren’t necessarily revelatory. That’s by design. Like the blurry abstractions of his super-telephoto images showing secret military installations in Nevada, the tiny blips of satellites streaking across the night sky in his new series of photos are meant more as reminders rather than as documentation.

The Microchip: Health, Privacy, Civil Rights And Freedom Under Siege

June 22, 2008
The Infinite Unknown

Introduction:

Governments will microchip…

…your animals as introduction, to have their foot in the door,

…prisoners so that they cannot so easily commit crimes anymore,

…your children so that they can be found if something “unexpected” happens to them,

…the rich so that they can be protected.

They sell this to the people like an insurance agent sells his products by using FEAR…

…and then the microchip will be mandatory for everybody.

Welcome to the New World Order and the Orwellian, Fascist, Police State.

PS: The Microchip is not just a transmitting device!

It is also a receiver, like your brain.

Now they can send frequencies, carrying information, directly to their selected target only!

This is a very effective way to control what you do, what you think, how you behave and it is also a nice way to control overpopulation.

How about taking out people like Ron Paul by causing a heart attack without leaving a trace of an assassination?

U.K. to Begin Microchipping Prisoners

Saturday, June 21, 2008
by: David Gutierrez

(NaturalNews) The British government is developing a plan to track current and former prisoners by means of microchips implanted under the skin, drawing intense criticism from probation officers and civil rights groups.

As a way to reduce prison crowding, many British prisoners are currently released under electronic monitoring, carried out by means of an ankle bracelet that transmits signals like those used by mobile phones.

Now the Ministry of Justice is exploring the possibility of injecting prisoners in the back of the arm with a radio frequency identification (RFID) chip that contains information about their name, address and criminal record. Such chips, which contain a built-in antenna, could be scanned by special readers. The implantation of RFID chips in luggage, pets and livestock has become increasingly popular in recent years.

In addition to monitoring incarcerated prisoners, the ministry hopes to use the chips on those who are on probation or other conditional release. By including a satellite uplink system in the chip, police would be able to use global positioning system (GPS) technology to track subjects’ exact locations at all times. According to advocates of such a measure, this could help keep sex offenders away from “forbidden” zones like schools.

Harry Fletcher, assistant general secretary of the National Association of Probation Officers, blasted the measure as degrading to the people chipped and of no benefit to probation officers.

“Knowing where offenders like pedophiles are does not mean you know what they are doing,” Fletcher said. “Treating people like pieces of meat does not seem to represent an improvement in the system to me.”

Shami Chakrabarti of the civil rights group Liberty had even stronger words:

“If the Home Office doesn’t understand why implanting a chip in someone is worse than an ankle bracelet, they don’t need a human-rights lawyer; they need a common-sense bypass.”

Quotes to contemplate on:

“If this were a dictatorship, it would be a heck of a lot easier, just so long as I’m the dictator.” – G. W. Bush

Who gives a flying fuck what the polls say,’ he screamed at a recent strategy meeting. ‘I’m the President and I’ll do whatever I goddamned please. They don’t know shit.’ – G. W. Bush

Stop throwing the Constitution in my face. It’s just a goddamned piece of paper! – G. W. Bush

Japanese Invent Car That Runs On Water

Source: Nikkei Business Publications

Genepax Co Ltd explained the technologies used in its new fuel cell system “Water Energy System (WES),” which uses water as a fuel and does not emit CO2.

The system can generate power just by supplying water and air to the fuel and air electrodes, respectively, the company said at the press conference, which took place June 12, 2008, at the Osaka Assembly Hall.

The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, the main feature of the new system is that it uses the company’s membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction.

Though the company did not reveal the details, it “succeeded in adopting a well-known process to produce hydrogen from water to the MEA,” said Hirasawa Kiyoshi, the company’s president. This process is allegedly similar to the mechanism that produces hydrogen by a reaction of metal hydride and water. But compared with the existing method, the new process is expected to produce hydrogen from water for longer time, the company said.

With the new process, the cell needs only water and air, eliminating the need for a hydrogen reformer and high-pressure hydrogen tank. Moreover, the MEA requires no special catalysts, and the required amount of rare metals such as platinum is almost the same as that of existing systems, Genepax said.

Unlike the direct methanol fuel cell (DMFC), which uses methanol as a fuel, the new system does not emit CO2. In addition, it is expected to have a longer life because catalyst degradation (poisoning) caused by CO does not occur on the fuel electrode side. As it has only been slightly more than a year since the company completed the prototype, it plans to collect more data on the product life.

At the conference, Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W. In the demonstration, the 120W fuel cell stack was first supplied with water by using a dry-cell battery operated pump. After power was generated, it was operated as a passive system with the pump turned off.

This time, the voltage of the fuel cell stack was 25-30V. Because the stack is composed of 40 cells connected in series, it is expected that the output per cell is 3W or higher, the voltage is about 0.5-0.7V, and the current is about 6-7A. The power density is likely to be not less than 30mW/cm2 because the reaction area of the cell is 10 x 10 cm.

Meanwhile, the 300W fuel cell system is an active system, which supplies water and air with a pump. In the demonstration, Genepax powered the TV and the lighting equipment with a lead-acid battery charged by using the system. In addition, the 300W system was mounted in the luggage room of a compact electric vehicle “Reva” manufactured by Takeoka Mini Car Products Co Ltd, and the vehicle was actually driven by the system.

Genepax initially planned to develop a 500W system, but failed to procure the materials for MEA in time and ended up in making a 300W system.

For the future, the company intends to provide 1kw-class generation systems for use in electric vehicles and houses. Instead of driving electric vehicles with this system alone, the company expects to use it as a generator to charge the secondary battery used in electric vehicles.

Although the production cost is currently about ¥2,000,000 (US$18,522), it can be reduced to ¥500,000 or lower if Genepax succeeds in mass production. The company believes that its fuel cell system can compete with residential solar cell systems if the cost can be reduced to this level.

American Inventor Presents an Answer to the World’s Water Crisis

Related article: Water crisis to be biggest world risk

(NaturalNews) Dean Kamen is not a new player in the innovator’s arena. He has been inventing and innovating ever since he dropped out of Worcester Polytechnic Institute in the 70’s. Since then, he invented such things as the insulin pump, a mobile dialysis system, and an all-terrain electric wheelchair called the iBot. His best-known invention is the Segway, a self-balancing, gyroscope-using, automatic-steering, scooter-like device that did not sell well in the U.S. but is expected to do better in Europe.

His newest invention could turn out to be world-changing. The term “revolutionary” comes to mind but may be too overused to express what this device could do for the world’s poor. It could save the lives of hundreds of millions of people in the third world. And it’s really quite simple. This invention answers the question — “How do you get drinkable water to the world’s thirsty?”

The Slingshot, A Revolutionary Water-Purifier

The invention, known as Slingshot, is basically a distiller. Distilling technology is not new. In fact, distillers have been around for decades. What makes this distiller unique is the low price and the large amount of water that can be produced. Other machines like the Slingshot can cost as much as $200,000 to $1 million. The Slingshot is expected to cost only $1,500. And it can filter 1,000 liters a day, using only 500 watts of electricity per hour. To put that into perspective, a toaster uses about 1,000 watts every time you make toast.

Possibly even more exciting than the cost-effectiveness and simplicity of the technology is its power. It can purify any source of moisture, whether ocean water, urine, or mud. And it does it all without filters, charcoal, or any other parts that must be replaced each time you use it.

The Slingshot has been slated for release within the next 12-18 months.

Saving Millions of Lives Every Year

“In the emerging world, in the under-developed world, a gallon of water is so precious that without it, you’re going to die,” says Kamen.

“In some places, the average amount of time per day spent looking for water that’s safe for their kids by women is four hours. And they carry this stuff, which weighs 62 pounds per cubic foot, four or five miles. And if it didn’t turn out to be the right stuff, or they put their hands in it and contaminated it, they spend the next day or two burying the babies.”

What will these women do with their extra 4 hours every day? How many families will be blessed by mothers who have the power to give water to their thirsty children? And with other inventions like the Merry-Go-Round power plant (see http://www.youtube.com/watch?v=uQu_Jppvzyk&eurl) , we may start to see our friends in the third-world finding a luxury that we have taken for granted for hundreds of years in the U.S. — fresh, drinkable water.

Pentagon OKs ‘brainwave binoculars’

THE Pentagon has approved $US6.7 million ($7m) to develop binoculars that would tap a user’s brainwaves to home in on threats.

Northrop Grumman Corporation said today it was leading an academic and industry consortium for the project, known as the Cognitive Technology Threat Warning System program, or CT2WS.

The plan featured a custom helmet equipped with electrodes placed on the scalp to record neural responses to the presence or absence of potential threats, Northrop said.

The brain’s input would “train the system’s algorithms, which will continue to be refined over time so that the warfighter is always presented with items of relevance to his mission”, the company said.

The contract was awarded by the Defence Advanced Projects Agency, or DARPA, a Pentagon arm that acts as a cradle of new technology for use by the US military.

The goal is to detect enemy forces and vehicles over 1-10km while surveying a 120deg or greater field of view, according to documents on DARPA’s website.

“At the same time we must look at the projected size, weight and power of the notional system to determine if the capabilities we are aiming for can be constrained into something fieldable by our military,” said DARPA spokeswoman Jan Walker.

Neither Northrop nor the military provided precise details on how the project might work if put into operation.

After the project’s initial 12-month, $US6.7m stage, DARPA has the option to extend the contract for two more phases to develop the subsystems and a final prototype of portable assemblies.

“A prototype is not a product, so if we are three years away from a prototype we might be five years or more away from a device that might be considered a product,” Ms Walker said.

Northrop Grumman said it was striving for “persistent surveillance” in the system to give early notice of any enemy “move-stop-move tactics”.

If and when deployed, such a system could play a role in such things as force protection, defeating roadside bombs, border surveillance and other advanced military and homeland defense applications, the company said.

Weapons lab develops world’s fastest computer dubbed Roadrunner

WASHINGTON – Scientists unveiled the world’s fastest supercomputer on Monday, a $100 million machine that for the first time has performed 1,000 trillion calculations per second in a sustained exercise.

The technology breakthrough was accomplished by engineers from the Los Alamos National Laboratory and the IBM Corp. on a computer to be used primarily on nuclear weapons work, including simulating nuclear explosions.

The computer, named Roadrunner, is twice as fast as IBM’s Blue Gene system at Lawrence Livermore National Laboratory, which itself is three times faster than any of the world’s other supercomputers, according to IBM.

“The computer is a speed demon. It will allow us to solve tremendous problems,” said Thomas D’Agostino, head of the National Nuclear Security Administration, which oversees nuclear weapons research and maintains the warhead stockpile.

The Future Is Now? Pretty Soon, at Least

Before we get to Ray Kurzweil’s plan for upgrading the “suboptimal software” in your brain, let me pass on some of the cheery news he brought to the World Science Festival last week in New York.

Do you have trouble sticking to a diet? Have patience. Within 10 years, Dr. Kurzweil explained, there will be a drug that lets you eat whatever you want without gaining weight.

Worried about greenhouse gas emissions? Have faith. Solar power may look terribly uneconomical at the moment, but with the exponential progress being made in nanoengineering, Dr. Kurzweil calculates that it’ll be cost-competitive with fossil fuels in just five years, and that within 20 years all our energy will come from clean sources.

Are you depressed by the prospect of dying? Well, if you can hang on another 15 years, your life expectancy will keep rising every year faster than you’re aging. And then, before the century is even half over, you can be around for the Singularity, that revolutionary transition when humans and/or machines start evolving into immortal beings with ever-improving software.

At least that’s Dr. Kurzweil’s calculation. It may sound too good to be true, but even his critics acknowledge he’s not your ordinary sci-fi fantasist. He is a futurist with a track record and enough credibility for the National Academy of Engineering to publish his sunny forecast for solar energy.

He makes his predictions using what he calls the Law of Accelerating Returns, a concept he illustrated at the festival with a history of his own inventions for the blind. In 1976, when he pioneered a device that could scan books and read them aloud, it was the size of a washing machine.

Two decades ago he predicted that “early in the 21st century” blind people would be able to read anything anywhere using a handheld device. In 2002 he narrowed the arrival date to 2008. On Thursday night at the festival, he pulled out a new gadget the size of a cellphone, and when he pointed it at the brochure for the science festival, it had no trouble reading the text aloud.

This invention, Dr. Kurzweil said, was no harder to anticipate than some of the predictions he made in the late 1980s, like the explosive growth of the Internet in the 1990s and a computer chess champion by 1998. (He was off by a year – Deep Blue’s chess victory came in 1997.)
