National Laboratories Press Release PHILADELPHIA April 7, 2003 — Throwing its hat into the ring of machines that offer the possibility of achieving controlled nuclear fusion, Sandia National Laboratories’ Z machine has created a hot dense plasma that produces thermonuclear neutrons, Sandia researchers announced today at a news conference at the April meeting of the American Physical Society in Philadelphia. The neutrons emanate from fusion reactions within a BB-sized deuterium capsule placed within the target of the huge machine. Compressing hot dense plasmas that produce neutrons is an important step toward realizing ignition, the level at which the fusion reaction becomes self-sustaining. The amount of energy a larger successor to Z could bring to bear offers the still-later possibility of high-yield fusion — the state in which much more energy is released than is needed to provoke the reaction initially to occur. The excess energy could be used for applications such as the generation of electricity, said Tom Mehlhorn, a project leader on the machine. Z causes reactions to occur neither by confining low density plasmas in dimensionally huge magnetic fields, as do tokomaks, nor by focusing intense laser beams on or around a target, as in laser fusion, but simply through the application of huge pulses of electricity applied with very sophisticated timing. The pulse creates an intense magnetic field that crushes tungsten wires into a foam cylinder to produce X-rays. The X-ray energy, striking the surface of the target capsule embedded in the cylinder, produces a shock wave that compresses the deuterium within the capsule, fusing enough deuterium to produce neutrons. "Pulsed power electrical systems have always been energy-rich but power-poor," said Ray Leeper, a Sandia manager. "That is, we can deliver a lot of energy, but it wasn’t clear we could concentrate it on a small enough area to create fusion. Now it seems clear we can do that." A partial confirmation of the result came about when theoretical predictions and lab outcomes were determined to be of the same order of magnitude. Predictions and measurements of the neutron yield were both of the order of 10 billion neutrons. The predicted neutron yield depends on the ion density temperature and volume. Those quantities were independently confirmed by X-ray spectroscopy measurements. Neutron pulses were observed as early as last summer but researchers were wary that the output was produced by interactions between the target and ions generated by Z’s processes, rather than within the capsule itself. Ion-generated neutrons were not the point of the experiment, since they would not scale up into a high-yield event in any later, more powerful version of Z. But a series of experiments completed in late March demonstrated that the production was within the capsule itself. To show this, researchers inserted xenon gas within the capsule. The gas prevented the capsule from getting hot during compression. Thus, the neutron yield dropped dramatically, as predicted. The action takes place within a container the size of a pencil eraser, called a hohlraum, at the center of the Z machine, itself a circular device about 120 feet in diameter. Sandia researchers Jim Bailey and Gordon Chandler led the experimental team and Steve Slutz performed theoretical calculations. Sandian Carlos Ruiz and Gary Cooper of the University of New Mexico performed the neutron measurements. Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000. With main facilities in Albuquerque, N.M., and Livermore, Calif., Sandia has major research and development responsibilities in national security, energy and environmental technologies, and economic competitiveness.

| Syria Next US Target for 'Regime Change' |
| By
Toby Harnden Belfast April 8, 2003 (Telegraph UK) - One of the main subjects on the agenda of the Belfast summit yesterday was Syria, the Pentagon's next likely target for "regime change" amid suspicions it allowed Saddam Hussein to transfer weapons of mass destruction within its borders. Although President George W Bush did not include Syria in his "axis of evil" of Iran, Iraq and North Korea in January 2001, since then American officials say they have seen growing evidence of support for terrorism by Damascus. American officials stress, however, that regime change can be achieved without military action. There are strong hopes in Washington for a popular revolution in Iran by democratic opposition groups inspired by what has happened in Iraq. President Bashar Assad, Syria's leader, has led Arab opposition to the Iraq war, stating that he hoped Saddam would remain in power. Donald Rumsfeld, the US Defense Secretary, recently accused Syria of providing military equipment to Saddam. Some US officials are also convinced that Mr. Assad has actively collaborated with Saddam and agreed to take weapons, including Scud missiles, from him so they would not be discovered in Iraq by United Nations inspectors. "Significant equipment, assets and perhaps even expertise was transferred, the first signs of which appeared in August or September 2002," a Bush administration official told The Telegraph. "It is quite possible that Iraqi nuclear scientists went to Syria and that Saddam's regime may retain part of its army there." Increasingly tough rhetoric from the Bush administration had made little fundamental difference to the Syrians, he added. "They behave only slightly when they're scared to death but the change is only limited and tactical." Satellite photographs revealed heavily guarded convoys moving from Iraq to Syria last year. "Put it this way, they wouldn't have needed that kind of security to move cattle." The official said that there were also well-founded fears that Iraq and Libya had also been co-operating and that weapons proliferation in the Middle East was one of the major problems facing the world. Colonel Gaddafi's regime was "scary close" to developing a nuclear weapon, he said. In December, Ariel Sharon, the Israeli prime minister, said: "We are certain that Iraq has recently moved chemical or biological weapons into Syria." This claim was subsequently investigated by John Bolton, US under-secretary of state for arms control and a prominent hawk in the Bush administration. Israeli sources said Mr. Bolton told Mr. Sharon that war with Iraq would force Syria and Libya to "come off the fence". When asked by The Telegraph last week whether Saddam had exported some of his weapons to Syria, Paul Wolfowitz, the US deputy defense secretary said: "We just don't know." There is firm resistance within the US State Department to Mr. Rumsfeld's hardline stance on Syria with many officials arguing, like their British counterparts, that Syria can be a partner in the war against terrorism if it is given encouragement rather than being threatened. Richard Murphy, US Assistant Secretary of State for Near Eastern Affairs from 1983 to 1989, said he did not believe armed conflict with Syria was on the immediate horizon. "Talk of a broader military conflict with Syria does not represent a decision taken by American policy makers. This is the view among the neo-conservatives, some of whom are in the administration. There's a perception that the time has come to spread democracy in the Middle East. Their view is that the US paid heavily on September 11 for having not stood by its principles in dealing with autocracies in the Middle East." But neo-conservatives, former Democrats with socially liberal views but a hawkish and ambitious vision of the use of American power abroad, include Mr Wolfowitz and Mr. Bolton and enjoy growing influence within the White House. |

Fire Wooden Bullets at Oakland Protesters By MARTHA MENDOZA AP National Writer OAKLAND April 7,
2003 (AP) - Police opened fire with non-lethal projectiles at an anti-war
protest at the Port of Oakland on Monday, injuring at least a dozen
demonstrators and six longshoremen standing nearby. "This is a level of injury as high as I've seen anywhere since Seattle in 1999," she said. About 200 of the
port demonstrators later marched to the federal building in Oakland,
blocking a street and chanting: "Out of the office and into the
streets! U.S. out of the Middle East!" They were joined by Oakland
City Council members Jane Bruner and Jean Quan. "I was
standing as far back as I could," said longshoremen Kevin Wilson.
"It was very scary. All of that force wasn't necessary." He said a union
arbitrator was evaluating the situation, trying to determine whether the
longshoremen should cross the protesters' picket line and go to work, when
police started firing. Sisters Ardeth Platte, 66, Jackie Hudson, 68, and Carol Gilbert, 55, were arrested for breaking into a Minuteman III missile silo site on Colorado's northeastern plains Oct. 6. They were charged with interfering with the nation's defense and causing property damage of more than $1,000. The nuns are peace
activists and have said they were compelled to act as war with Iraq moved
closer and because the United States has never promised not to use nuclear
weapons. Their defense lawyers argued the nuns' action was symbolic and
never jeopardized national security. The women entered
the Minuteman III missile silo as part of a symbolic disarmament, reading
Bible verses about pounding swords into plowshares and singing hymns,
Gerash said during the trial. They pounded on the 110-ton concrete lid
with hammers. Television footage
showed one protester attached to the bow of the ship and unfurling a
"No War" banner, while another hooked on to the stern after two
small boats carrying protesters broke through a water police cordon. NJ Residents

| Elephants Liberate Herd of Antelope! |
| Empangeni,
Zululand April 8, 2003 (SAPA) - A conservation team were left baffled when
11 elephants arrived at their camp in Empangeni to rescue a herd of
antelope who were being held in a boma. Conservationist Lawrence Anthony said on Tuesday that a private game capture company had been working on the Thula Thula Exclusive Private Game Reserve capturing antelope that were to be relocated for a breeding programme. Shortly before relocation the antelope were being housed in a boma enclosure. The team were settling in for the night when a herd of 11 elephants approached the boma, he said. "The herd circled the enclosure while the capture team watched warily, thinking the herd were after lucerne being used to feed the antelope," Lawrence said. "This went on for quite a while until the herd seemed to back off from the boma perimeter fence." The herd's matriarch, named Nana, approached the enclosure gates and began tampering with the metal latches holding the gates closed. She carefully undid all the latches with her trunk, swung the gate open and stood back with her herd. "At this stage the onlookers realized this was not a mission for free food, but actually a rescue," said Lawrence. The herd watched the antelope leave the boma and dart off before they walked off into the night. Thula Thula resident Ecologist Brendon Whittington-Jones said: "Elephant are naturally inquisitive, but this behavior is certainly most unusual and cannot be explained in scientific terms". |
| Ernest Hemingway and Marlene Dietrich? |
| By
Greg Frost BOSTON April 7, 2003 (Reuters) - Thirty letters written by author Ernest Hemingway to screen siren Marlene Dietrich along with several early drafts of his stories and poems have been donated to the John F. Kennedy Library and Museum, the library announced on Monday. Deborah Leff, director of the library in Boston, called the donation a "rich addition" to the center, which is already home to 95 percent of Hemingway's manuscripts and correspondence. Library staff acknowledged that they only learned of the documents' existence within the past few years. "Here are two of the most iconic figures of the 20th century -- one of the great American writers and one of the great actresses, both of them larger than life -- and shared among them are these extraordinary, intimate and loving letters," Leff told Reuters. The documents, which were given to the library by Dietrich's daughter, Maria Riva, will be made public in 2007. Riva has kept them since her mother died in Paris in 1992. Peter Riva, Maria's son, has seen the letters and said they depict a relationship of sincere "camaraderie" that was more than friendship but fell short of an all-out physical romance. "You read these letters and you come to understand that theirs was a relationship of firm, fast friendship based on an experience of the world they lived in," he said. "They could bare their souls in a way that was unusual then, and probably still is today." Riva, a literary agent based in New York state, said his grandmother and the Nobel and Pulitzer prizewinning author never escalated their relationship to the height of physical love, but they nonetheless felt great passion for one another. "Marlene was this firm, independent, capable human being who just happened to be a beautiful woman, (and) Hemingway brought to the table the ability to celebrate and understand women in a way that she thought was the right way," he said. "He knew how women ticked." 'BREAKS YOUR HEART' Hemingway once said about Dietrich: "If she had nothing more than her voice she could break your heart with it. But she has that beautiful body and the timeless loveliness of her face. It makes no difference how she breaks your heart if she is there to mend it." Born in 1901, Dietrich became the quintessential blonde bombshell. She struggled through the roaring 1920s in local theaters as a singer and small-time actress before her breakthrough as a vamp in the movie "The Blue Angel" in 1930. Hemingway became the second most-translated author in English after Agatha Christie with masterpieces such as "The Sun Also Rises," "For Whom the Bell Tolls," "A Farewell to Arms," and "The Old Man and the Sea," which led to a Nobel Prize in the early 1950s. Like his characters who exhibited grace under fire, he gained a reputation for drinking and womanizing (he married four times) and became a larger-than-life expatriate on the frontlines of battlefields and bullfighting rings. He committed suicide at age 61. The donation comprises 30 letters, cards and other documents that both Hemingway and his wife, Mary, wrote to Dietrich from 1949 to 1959. They were mailed from Idaho, Kenya, Italy, and other disparate postmarks. Apart from the correspondence, the donation also includes drafts of three Hemingway stories -- "Across the River and Into the Trees," "The Good Lion," and "The Story of the Faithful Bull" -- and two Hemingway poems, "First Poem to Mary in London" and "Poem to Mary." Peter Riva said it is believed that the other half of the correspondence -- Dietrich's letters to Hemingway -- may still be in Cuba, where the author lived for several years. An effort is under way to bring more of the author's property back to the United States from the communist Caribbean island nation. |
| Unlocking Prime Numbers |
| By
Dr David Whitehouse BBC News Science Editor Germany April 4, 2003 (BBC) - A pair of mathematicians has made a breakthrough in understanding so-called prime numbers, numbers that can only be divided by themselves and one. Other mathematicians have described the advance as the most important in the field in decades. It was made by Dan Goldston, of San Jose State University, and Cem Yildirim, of Bogazici University in Istanbul, Turkey. It has just been announced at a conference in Germany on Algorithmic Number Theory. The advance is related to an idea called the twin prime conjecture. This idea, still unproved, is that there are an infinite number of pairs of prime numbers that differ only by two. "Neither of us ever expected to get particularly good results by this method. It's actually completely amazing to me," says Goldston. Commenting on the breakthrough, Hugh Montgomery, a mathematician at the University of Michigan in Ann Arbor, US, says that Goldston has really broken a barrier. Primes have always fascinated mankind. The third century BC Greek mathematician Eratosthenes developed a way to find the prime numbers. Over the years, mathematicians such as Pierre de Fermat in the 17th Century, Georg Riemann in the 19th Century and Godfrey Hardy in the 20th have advanced our understanding of these strange numbers. One of the important things about primes is that they are the building blocks of the integers - whole numbers. Primes can be multiplied to obtain all of the other integers. A curious observation is that primes occur in twins with a surprising regularity. For example: 11 and 13; 17 and 19; 29 and 31; 41 and 43; 59 and 61. Just as with single
primes, the frequency of twin primes decreases as one gets to larger
numbers. But do they completely fizzle out beyond some very large number?
That is the big question. Around a trillion, for instance, only about one
in every 28 numbers is a prime. Or rather, he approached the dilemma by first tackling a more manageable piece of the problem. He asked if it was possible to find prime numbers that might not be twins, but that were much closer together than average? After many years of study, he was able to show it was. According to Brian
Conrey, of the American Institute of Mathematics, the way Goldston went
about solving the problem was just as important as the result. |
| Democrats Criticize Bush Forest Plan |
| WASHINGTON
April 8, 2003 (Reuters) — The Bush administration should drop proposed
rules to streamline forest management because the changes would reward the
U.S. timber industry while damaging pristine wilderness and wildlife
habitat, 107 Democratic members of the House of Representatives said
Monday. In a letter to President Bush, the Democrats said the administration wanted to remove public participation in forest planning and ease rules designed to protect 192 million acres of national forests. "We are deeply disturbed by the scope and breadth of recent initiatives undertaken by your Administration to transform national forest policy," the letter said. Lawmakers said proposed changes to the National Forest Management Act and National Environmental Protection Act were nothing more than "radical proposals" that give the U.S. Forest Service more power to change forest policy with little public input. "The cumulative effect of these Administration proposals would be to significantly lower environmental standards for our national forests to a level far below what is now required for other public lands," said Rep. Nick Rahall, a West Virginia Democrat who signed the letter. "The U.S. Forest Service would be much less accountable to the public, or the judiciary, regarding commercial logging and other land-use decisions," he said. The letter was also signed by Rep. John Dingell of Michigan, the ranking Democrat on the House Energy and Commerce committee. The Bush administration said the proposed forest rules were not intended to boost access to forests by large timber companies, but were needed to remove some unnecessary and cumbersome environmental requirements that slow down efforts to protect forests. Among the rules proposed by the administration include the "Healthy Forests Initiative" that would trim some environmental regulations in 10 million acres (4 million hectares) of fire-prone forests to speed the removal of dangerous underbrush and dead trees that serve as fuel in spreading wildfires. And in November, the administration unveiled a plan it said would "cut out red tape" and reduce court appeals that have muddled forest policy by giving local forest managers greater control over commercial activities in 155 federal forests. Both proposals have yet to be approved by Congress. |
| Chimps and Gorillas Critically Endangered! |
| Wildlife
Conservation Society Press Release NEW YORK April 6, 2003 - Scientists from the New York-based Wildlife Conservation Society, Princeton University and other organizations have reported in the latest issue of the journal Nature that a dramatic decline of gorillas and chimpanzees is taking place in western equatorial Africa, the last stronghold for great apes on the continent. Ravaged first by a wave of commercial hunting, and more recently by an outbreak of the deadly Ebola virus, gorillas and chimpanzees could be pushed to the brink of extinction during the next decade without immediate protective measures, scientists warn. Looking at populations in the central African nation of Gabon, which still retains 80 percent of its forest cover, scientists discovered a 56 percent drop in chimpanzee and gorilla numbers had taken place between 1983 and 2000. Such a decline justifies that both species should be reclassified from "endangered" to "critically endangered" according to World Conservation Union criteria, the authors of the study say. "This is a catastrophic decline of great apes in an area that contains the bulk of the world's remaining populations. If chimps and gorillas continue to disappear at the current rate, our closest relatives will be confined to a few small pockets in a matter of years," said the paper's lead author, Dr. Peter Walsh, a WCS biologist based at Princeton University. "If chimpanzees and gorillas are in trouble in Gabon, an area known for its pristine, unbroken forests, than we have a species-wide crisis on our hands when it comes to saving these animals," said WCS conservationist Dr. Lee White, who has worked in Gabon for the past decade. Dr. Walsh and his colleagues say that aggressive investments in Ebola prevention, law enforcement and protected area management are needed to ensure the survival of these two species. The head of WCS's Field Veterinary Program, Dr. William Karesh, says that experts agree that expanded field research on Ebola transmission in wildlife populations is urgently needed, as current knowledge is inadequate to intervene effectively in the epidemic. More support is also required to fight the wave of ape poaching that has followed the intrusion of mechanized logging into once remote areas. Scientists believe the great ape decline is not restricted to Gabon. Neighboring Republic of Congo and other countries in the region have higher human densities and worse deforestation than Gabon. An outbreak of Ebola hemorrhagic fever in Gabon nearly a decade ago may have wiped out tens of thousands of gorillas and chimps. The disease has emerged again more recently in Gabon and the Congo with gorillas and chimpanzees rapidly dying. Scientists also
suspect that widespread civil unrest in Democratic Republic of Congo has
caused further declines among gorillas and chimps in that region. |

Angel Coming Back? With Giles and Spike? By FLAtRich Hollywood April 8, 2003 (eXoNews) - The rumor mills are at it again, and we're all a part of that so why not? First there was the Superman-tied rumor that Angel would return in the fall. An informant to Dark Horizons claimed this was the reason David Boreanaz was not tagged by Warners to don the red cape for the upcoming three-picture Superman deal. That one was kinda crushed when the WB announced six shows would return next fall and Angel was not among them. The WB announcement was about "early renewals", though, so Angel fans were undeterred. Now Kristin, E! Online's mistress of word of mouth, says the prospect of Buffy cast actors jumping to Angel has the WB "very excited." Kristen supplies quotes from James Marsters and Anthony Stewart Head saying they may show up on Angel next season. That, of course, leads again to the yet unfounded conclusion that Angel's return is a sure thing. Unfounded because
ratings are everything and, despite a slight rise since Angel was assigned
the WB's Wednesday at 9PM slot, Angel still averages far lower ratings
than Smallville and the other WB headliners who were renewed. Even with the Buffy
era coming to an end, fans should take solace in the overall success of
genre entertainment on TV and in the movies this year. It's a Golden Age
