Wayne, here's the headline...Crystal power Palmtop Nuclear Fusion Device Invented By Michael Schirber LiveScience Staff Writer posted: 27 April 2005 01:00 pm ET The nuclear reaction that powers the Sun has been reproduced in a pocket-sized device, scientists announced today. Researchers have for years tried to harness nuclear fusion to power the world. But its cousin, nuclear fission -- the breaking apart of atoms -- is the only method so far commercially viable. The latest invention is not in the same league as efforts to build complex commercial reactors. The new device creates a relatively small number of reactions, and requires more energy to operate than it produces. The Real Deal (AP) - Previous claims of tabletop fusion have been met with skepticism and even derision by physicists. In one of the most notable cases, Dr. B. Stanley Pons of the University of Utah and Martin Fleischmann of Southampton University in England shocked the world in 1989 when they announced that they had achieved so-called cold fusion at room temperature. Their work was discredited after repeated attempts to reproduce it failed. Fusion experts noted that the new UCLA experiment is credible because, unlike the 1989 work, it did not violate basic principles of physics. "This doesn't have any controversy in it because they're using a tried and true method,'' said David Ruzic, professor of nuclear and plasma engineering at the University of Illinois at Urbana-Champaign. "There's no mystery in terms of the physics.'' -- Associated Press But the configuration is so small and simple that its creators think it may inspire unforeseen applications. "I certainly find it interesting that you can heat a cubic centimeter crystal in your hand, then plunge it in cold water and it will cause nuclear fusion," Seth Putterman from the University of California Los Angeles told LiveScience. Putterman's lay description greatly oversimplifies how the compact apparatus works. Specifically, Putterman and collaborators heat a pyroelectric crystal, lithium tantalite, from minus 30 degrees Fahrenheit to plus 45 in a matter of minutes. This generates an electrical charge -- 100,000 volts -- across the tiny crystal, which is housed in a chamber filled with deuterium gas, a heavy form of hydrogen. The high voltage is focused onto a needle-thin tip, which strips electrons from nearby deuterium nuclei and then accelerates them at a solid target containing deuterium. When two deuterium nuclei collide together at high speed, they fuse to form helium. The Sun also fuses atoms in thermonuclear reactions that create light and heat. The byproduct of the newly discovered lab reaction is a particle called the neutron. The scientists detect about 1,000 neutrons per second. Because neutrons are so penetrating, Putterman said that a hand-held neutron source might one-day be used to do geologic surveys or to look into cargo containers for nuclear devices. "Current neutron generators are extremely cumbersome," Putterman said. "They are about as big as a dentists X-ray machine, so you canÂt carry them into the field." Pyroelectric crystals could also provide a beam of ions for use as a microthruster in a miniature spacecraft. The research is described in the April 28 issue of the journal Nature.

Oh, all is forgiven, flyleft. I was joshing anyway, although I'd gladly forgo that particular event if not having kids meant I could - not my idea of entertainment! *chuckle* The joys of fibrobrain and pain meds and too little sleep... I just glanced back at the bit above where I said I wished the mammo tech had just taken the relevant parts off to do their thing with them and the King Missile song "Detachable P&n!s" popped into my head, although it was playing in my head as "Detachable B**bies". (Had to look that up, for some reason I thought it was Primus. Not quite my taste in music but I used to work with some chefs who played really weird stuff in the kitchen during prep time. They introduced me to They Might Be Giants - we always played "Minimum Wage" from the "Flood" album just before we opened for the day, synching turning the door key to the whipcrack - so I forgave them a lot.)

I believe that experiences are shaped by experiences themselves. Especially in the medical field, weather it be human or veterinarian. I have just had so many problems misdiagnosed by vets that I've lost count. I have a memorable one. My Shepherd/Lab, Tara, about 10 years old had an off smell. Not a dirty smell, just an off smell. I couldn't figure out what it was, my regular vet wasn't concerned, and my dermatology vet said not to worry. Weeks past, and the smell got worse, plus Tara's coat was appearing very oily. Then one day she started to bite herself severely trying to relieve itching. She was literally damaging herself trying to get relief. My regular vet consulted with dermatology vet, and they both agreed that the dog had "fox mites" even though there was no evidence of them. Treatments that lasted about three weeks took place. In the meantime, the situation was getting worse. By this time, Tara had chewed off at least half of her fur and had severe infections. I was sleeping with her on the floor to comfort her. Because I was so concerned, I took her into dermatology vet and left her for a day for observation. Again, vet said that medication was working (even though I could see that it wasn't) and that we should continue with the medication prescribed. The next day the situation took a drastic turn for the worse, and I decided I couldn't take it any more, and the dog was suffering. I was so desperate that I called the Pennsylvania Veterinary School and was ready to take her there from Maryland. They told me that the best dermatology vet to be treating her was the one I had. The day I decided that things just had to end, I located another dermatology vet. I took in Tara, and the vet came up with a completely different infection for a diagnosis. In short, the treatment was taking place for the wrong problem for at least three weeks, new vet fixed things, and Tara lived for another 4 years. This experience and others prior and after, have made me extremely cautious when it comes to what is being done to my pets. I have also learned that if there are multiple vets in a practice, things can take place to increase revenue that simply should not be allowed. But again, when we who do not have formal training, we take our pets to someone who we think we can trust to fix things. I have come to rely heavily on all advice, weather it could be wrong or right when health issues come up with my dogs. When I get all of the information I can find in front of me, I weigh my decision, consult with at least 2-3 other vets, and I alone have the final say, as to what is going to happen to my pets. Just a thought. SG

I ran out to my bank today to transfer some money to my daughter's account. She will have a large income tax return, but that is a couple of weeks away. She lives 800 miles away and is snow bound in Maryland. Their schools have been closed all week and she has not been able to go to her job. That affects her paycheck. I'm happy that I could loan her grocery, gasoline and rent money. The money arrived in her bank account about 15 minutes after I made the transfer, and she did not have to take her car out of its parking space. If she had moved it, her space would have been taken in a flash and she would have had no place to park when she returned home. Folks, it s big mess in Maryland. Snow plows have nowhere to push the snow, so they move it from pile to pile. Some side streets were blocked over night by snow piles left by the plow. (Hagerstown, MD)
