  • Japan To Restart Two Nuclear Reactors

    09/14/2014 8:52:30 PM PDT · by jonatron · 8 replies
    Japan’s nuclear watchdog has given the green light for two reactors to restart but the operator still has to persuade local communities they are safe. sendai-plant Widespread anti-nuclear sentiment has simmered in Japan ever since an earthquake and tsunami in March 2011 caused meltdowns at the Fukushima power plant, sparking the worst atomic disaster since Chernobyl. The country’s nuclear reactors were switched off after the catastrophe. Two reactors were briefly restarted last year but all of Japan’s nuclear plants are currently offline. The go-ahead from the Nuclear Regulatory Authority (NRA) for two reactors at the Sendai plant (pictured) in southern...
  • NASA: New "impossible" engine works, could change space travel forever

    Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why. Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be...

    Let me geek out on you (I love science) and explain to you the science (I love science) and why this had previously been confined to the pages of science fiction (I am a nerd; and oh Dear Sweet Bunsen-Burner Lighting Lord, do I love science). So it's a pretty firmly established principle that every act causes, and requires, an equal and opposite reaction. If I understand this right (did I mention I love science?), this means that any space vessel will have to carry with it an enormous amount of reaction mass. You can't -- we think, or thought...
  • Glyphosate ("Roundup") Responsible for Modern Human Diseases

    Entropy ^ | 4-18-2013 | Anthony Samsel and Stephanie Seneff
    Abstract: Glyphosate, the active ingredient in Roundup®, is the most popular herbicide used worldwide. The industry asserts it is minimally toxic to humans, but here we argue otherwise. Residues are found in the main foods of the Western diet, comprised primarily of sugar, corn, soy and wheat. Glyphosate's inhibition of cytochrome P450 (CYP) enzymes is an overlooked component of its toxicity to mammals. CYP enzymes play crucial roles in biology, one of which is to detoxify xenobiotics. Thus, glyphosate enhances the damaging effects of other food borne chemical residues and environmental toxins. Negative impact on the body is insidious and...

    Despite 50 years of research on high-power microwaves, the US military has yet to produce a usable weapon. For some Pentagon officials, the demonstration in October 2007 must have seemed like a dream come true — an opportunity to blast reporters with a beam of energy that causes searing pain. The event in Quantico, Virginia, was to be a rare public showing for the US Air Force's Active Denial System: a prototype non-lethal crowd-control weapon that emits a beam of microwaves at 95 gigahertz. Radiation at that frequency penetrates less than half a millimetre into the skin, so the beam...

    Want to participate in smacking down the criminal global banking cartel? Here’s how to do it. Sell the likely fraudulent SLV and GLD ETFs, cease participating in the fraudulent gold/silver futures markets, buy physical gold and silver, and buy gold/silver mining stocks. The good news is (1) This is a simple strategy; and (2) Buy wisely, and you will likely build significant wealth while participating in this strategy. The fraudulent immoral monetary system that bankers have imposed upon the world that steals money from savers and creditors and transfers wealth to governments, debtors and bankers can only be perpetuated by...

    The microwaves that cell phones emit can interact with human tissue in an entirely new way, says theoretical biologist at a government lab If there's one topic likely to generate spit-flecked ire, it is the controversy over the potential health threat posed by cell phone signals. That debate is likely to flare following the publication today of some new ideas on this topic from Bill Bruno, a theoretical biologist at Los Alamos National Laboratory in New Mexico.The big question is whether signals from cell phones or cell phone towers can damage biological tissue. On the one hand, there is a...

    Space War ^ | 2/11/2010 | Maria Callier/Air Force Office of Scientific Research
    Air Force Research Laboratory-funded researchers at the University of Michigan invented a new type of magnetron that may be used in defeating enemy electronics. A vital component of military radar systems since World War II, a magnetron is a kind of vacuum tube that serves as the frequency source in microwave ovens, radar systems, and other high-power microwave circuits. The newly devised technology--which is more compact, exhibits faster start-up, and demonstrates higher peak and average power than current devices--should enable higher-power, higher-frequency operation and, thus, improved potential for jamming and defeat of adversarial systems. While basic magnetron design has changed...

    EADS Astrium engineers are working on an orbital solar power concept that they think will be competitive with other technologies but safer to use. Solar power would be collected in space and beamed to Earth using high-power infrared lasers so the energy could be used in remote regions, areas hit by natural disasters and other places where terrestrial power is not readily available. Astrium Chief Technical Officer Robert Laine says the concept offers certain advantages compared to competing technologies such as microwaves—notably a much smaller health risk. The idea of using IR lasers for energy transmission has been around for...
  • Chip Implants Linked To Animal Tumors

    Ap via Yahoo ^ | Todd Lewan
    When the U.S. Food and Drug Administration approved implanting microchips in humans, the manufacturer said it would save lives, letting doctors scan the tiny transponders to access patients' medical records almost instantly. The FDA found "reasonable assurance" the device was safe, and a sub-agency even called it one of 2005's top "innovative technologies." But neither the company nor the regulators publicly mentioned this: A series of veterinary and toxicology studies, dating to the mid-1990s, stated that chip implants had "induced" malignant tumors in some lab mice and rats. "The transponders were the cause of the tumors," said Keith Johnson, a...

    Increasingly, physicists are constructing materials that bend light the “wrong” way, an optical trick that could lead to sharper-than-ever lenses or maybe even make objects disappear. Last October, scientists at Duke demonstrated a working cloaking device, hiding whatever was placed inside, although it worked only for microwaves. In the experiment, a beam of microwave light split in two as it flowed around a specially designed cylinder and then almost seamlessly merged back together on the other side. That meant that an object placed inside the cylinder was effectively invisible. No light waves bounced off the object, and someone looking at...

    HOUSTON - Congressman Nick Lampson, newly elected to the seat once held by former House Majority Leader Tom DeLay, underwent a procedure Friday to open up a partially blocked blood vessel, his spokeswoman said. Doctors at Christus St. John Hospital in suburban Houston performed the angioplasty on the 61-year-old Lampson and placed a stent in the vessel. Lampson was "conscious, alert and in good spirits throughout the procedure," spokeswoman Carrie Chess said in a statement. He was expected to be discharged Saturday. His wife, Susan Lampson, drove him to the hospital Thursday night because he started feeling sick during dinner....

    Home safety: The jarring truth BY DAVE BARRY Feb.6, 2005 (This classic Dave Barry column was originally published on Feb. 18,1990.) Today's Practical Homemaker Topic is: Useful Cooking Tips and Hints. Cooking is one of the major cultural achievements, along with golf, that separate human beings from animals. Animals don't cook. When they encounter something that might be food, they just snork it down. My editor's dog, Clementine, once ate aquarium gravel without even heating it up. Some scientists believe that ants might cook. The reasoning here is that if you look at the kinds of culinary treasures that worker...

    As the 21st century unfolds, radically different forms of air and space vehicles will replace the clunky machines of today, whisking passengers at ultra-high speed around the Earth and outward into space. Laboratories scattered around the world are delving into novel and exotic forms of propulsion. Breakthrough physics could well make possible ambitious human treks across interstellar distances. Work is underway to harness antimatter as a way to shave travel time to the Moon down to minutes, or between Earth and Mars to a day. Meanwhile, laser and microwave technology is rapidly advancing the idea of beaming people and payloads...

The way Thompson describes it, the "HPM" sound almost too good to be true: They "fry the sophisticated computers and electronic gear necessary to produce, protect store and deliver [chemical and biological] agents. The powerful elctromagnetic pulses can travel into deeply buried bunkers through ventilation shafts, plumbing and antennas. But unlike conventional explosives, they won't spew deadly agents into the air, where they could poison Iraqi civilians or advancing...
