Radio Frequencies Help Burn Salt Water

By David Templeton, Pittsburgh Post-Gazette
Tue, 11 Sep 2007, 11:41AM

ERIE, Pa. - An Erie cancer researcher has found a way to burn salt water, a novel invention that is being touted by one chemist as the "most remarkable" water science discovery in a century.

John Kanzius happened upon the discovery accidentally when he tried to desalinate seawater with a radio-frequency generator he developed to treat cancer. He discovered that as long as the salt water was exposed to the radio frequencies, it would burn.

The discovery has scientists excited by the prospect of using salt water, the most abundant resource on earth, as a fuel.

Rustum Roy, a Penn State University chemist, has held demonstrations at his State College lab to confirm his own observations.

The radio frequencies act to weaken the bonds between the elements that make up salt water, releasing the hydrogen, Roy said. Once ignited, the hydrogen will burn as long as it is exposed to the frequencies, he said.

The discovery is "the most remarkable in water science in 100 years," Roy said.

"This is the most abundant element in the world. It is everywhere," Roy said. "Seeing it burn gives me the chills."

Roy will meet this week with officials from the Department of Energy and the Department of Defense to try to obtain research funding.

The scientists want to find out whether the energy output from the burning hydrogen — which reached a heat of more than 3,000 degrees Fahrenheit — would be enough to power a car or other heavy machinery.

"We will get our ideas together and check this out and see where it leads," Roy said. "The potential is huge."

Gene 'controls body fat levels'

BBC News
9/11/07

A single gene can keep in check the tendency to pile on fat, scientists have shown.

The University of Texas team manipulated the gene, called adipose, to alter the amount of fat tissue laid down by fruit flies, worms and mice.

If the same effect could be achieved in humans, which also carry the gene, it is hoped it could lead to new ways to fight obesity and diabetes.

The study is published in the journal Cell Metabolism.

Lead researcher Dr Jonathan Graff said: "From worms to mammals, this gene controls fat formation.

"It could explain why so many people struggle to lose weight, and suggests an entirely new direction for developing medical treatments that address the current epidemic of diabetes and obesity.

"Maybe if you could affect this gene, even just a little bit, you might have a beneficial effect on fat."

The adipose gene was discovered in fat fruit flies more than 50 years ago, but scientists had not pinned down its exact role.

The Texas team used several methods to turn the gene on and off at different stages of the animals' lives and in various parts of their bodies.

Their work suggested that the gene acts as a high-level master switch that tells the body whether to accumulate or burn fat.

Health impact

Mice with experimentally increased adipose activity ate as much or more than normal mice.

However, they were leaner, had diabetes-resistant fat cells, and were better able to control insulin and blood-sugar metabolism.

In contrast, animals with reduced adipose activity were fatter and less healthy, and had diabetes.

The researchers also showed that gene activity could be turned up or down, not just on or off.

Dr Graff said this increased the potential to manipulate its effect to treat obesity.

The next step will be to probe further the exact mechanisms by which the gene exerts its control.

Dr David Haslam, clinical director of the National Obesity Forum, warned that it could take many years to develop genetic treatments for obesity.

In the meantime, he said, the only way to tackle the problem effectively was to encourage people to eat healthily and take exercise.

"I don't want patients coming to me saying: 'It's not what I eat, it's all in my genes'," he said.

"Don't give my patients another excuse to be victims."

Surprise Strategy: Bees Smother Enemies

Charles Q. Choi
LiveScience.com
Mon Sep 17, 12:55 PM ET

Cyprian honeybees don't smother their enemies with kindness—they just smother them to death, research now reveals.

This novel strategy has never been seen before in insects, "and probably in all animal species," apidologist Gerard Arnold at the National Center of Scientific Research in France, told LiveScience.

Cyprian honeybees (Apis mellifera cypria) do possess stingers to defend themselves. However, their archenemy, the Oriental hornet (Vespa orientalis), is protected from such attacks by their hard body armor. The predatory hornets tend to attack bee colonies en masse in the middle of the autumn, explained researcher Alexandros Papachristoforou of Aristotle University of Thessaloniki, Greece.

Previous studies revealed Asian honeybees can kill hornets by completely engulfing them, making the predators die from the heat inside the ball of bees—a strategy dubbed "thermo-balling."

However, Oriental hornets are theoretically resistant to thermo-balling, adapted as they are to the hot and dry climate of Cyprus. Although the heat inside a thermo-ball can reach 111 degrees F (44 degrees C), the heat-resistant Oriental hornet only keels over at temperatures of 122 degrees F (50 degrees C) or more.

Now scientists find Cyprian honeybees can kill hornets by suffocating them, a strategy the researchers have dubbed "asphyxia-balling."

"The domestic bee has never ceased surprising us," Arnold said. "Under stressful conditions, honeybees can develop remarkable mechanisms in order to survive."

The scientists collected live insects from Cyprus and took them back in their hand luggage for study in their labs. "Knowing that the hornets could somehow destroy the cage that you have trapped them" was "a very funny and uncomfortable situation," Papachristoforou recalled.

Hornets normally breathe via small openings in their sides called spiracles. These are covered by structures known as tergites.

In their experiments, the researchers saw that bees mob the guts of hornets, covering the spiracles. To see if the bees killed the hornets using smothering, the scientists held open the tergites of some hornets with tiny plastic blocks. They found bees took twice as long to kill such modified hornets—roughly two hours instead of one.

"To kill the high-temperature-tolerant hornet, Cyprian honeybees have developed an alternate strategy to thermo-balling and stinging," Papachristoforou said. "They appear to have identified the hornets' 'Achilles heel' by asphyxiating the predator."

Papachristoforou, Arnold and their colleagues will detail their findings in the Sept. 18 issue of the journal Current Biology.

Life growing in Chernobyl
There has been an exciting new biological discovery inside the tomb of the Chernobyl reactor. Like out of some B-grade sci fi movie, a robot sent into the reactor discovered a thick coat of black slime growing on the walls. Since it is highly radioactive in there, scientists didn’t expect to find anything living, let alone thriving. The robot was instructed to obtain samples of the slime, which it did, and upon examination…the slime was even more amazing than was thought at first glance.

This slime, a collection of several fungi actually, was more than just surviving in a radioactive environment, it was actually using gamma radiation as a food source. Samples of these fungi grew significantly faster when exposed to gamma radiation at 500 times the normal background radiation level. The fungi appear to use melanin, a chemical found in human skin as well, in the same fashion as plants use chlorophyll. That is to say, the melanin molecule gets struck by a gamma ray and its chemistry is altered. This is an amazing discovery, no one had even suspected that something like this was possible.

Aside from its novelty value, this discovery leads to some interesting speculation and potential research. Humans have melanin molecules in their skin cells, does this mean that humans are getting some of their energy from radiation? This also implies there could be organisms living in space where ionizing radiation is plentiful. I’ve always been a big panspermia proponent, the idea that life did not originate on Earth but is actually common in the cosmos. Organisms that can live in space certainly gives more credence to this idea.

Possibly this could also be used to create plants or mushrooms that could grow in space, serving as a food source for space travellers. Maybe these fungi could be modified and used somehow to clean up radiation contaminated environments. There’s quite a few of those, in fact the disposal of radioactive waste is still a huge and unsolved problem. Now the fungi couldn’t actually eat the radioactive isotopes, I’m not saying that, but if they can live in radioactive environments they might be used to somehow scour out or concentrate the radioactive isotopes in such a way as to facilitate their clean up.

Imagine, there’s fallout from a nuclear accident and what do the guys in suits do? They show up, spray mushroom spores over everything, and a few weeks later the mushrooms are harvested and disposed of while the contaminated area is now radiation free. It would certainly be useful, the picture at the top shows the still abandoned town of Priyat, Ukraine. It was built to house the workers at the Chernobyl nuclear power plant, and was evacuated within hours of the accident.

An excellent story about the Chernobyl disaster and Pripyat is at the Ghost Town link. Just be aware that, no, Elana didn’t actually ride her motorcycle through the radiation contaminated zone, that was poetic license on her part. (Motorcycle enthusiasts have motorcycled across Europe hoping to duplicate her tour, only to be told by the guards that that motorcycles are not allowed in the contaminated zone.) The pictures and descriptions are accurate though, some of the images are incredibly poignant. Just think, a whole town where the inhabitants fled without warning, leaving all of their possessions behind.

Fortunately the Chernobyl reactor was an old and unsafe design, only one other reactor in the world was built the same way. It was right here in Berkeley, a research reactor built on campus in the fifties. It was sagely decided to quietly shut it down after Chernobyl; while it couldn’t have had an accident on the scale of Chernobyl, the locals were a little concerned anyhow. In fact it was a block away from my favourite burrito place, yikes.

Germs taken to space come back deadlier

By RANDOLPH E. SCHMID, AP Science Writer
September 24, 2007

It sounds like the plot for a scary B-movie: Germs go into space on a rocket and come back stronger and deadlier than ever. Except, it really happened.

The germ: Salmonella, best known as a culprit of food poisoning. The trip: Space Shuttle STS-115, September 2006. The reason: Scientists wanted to see how space travel affects germs, so they took some along — carefully wrapped — for the ride. The result: Mice fed the space germs were three times more likely to get sick and died quicker than others fed identical germs that had remained behind on Earth.

"Wherever humans go, microbes go, you can't sterilize humans. Wherever we go, under the oceans or orbiting the earth, the microbes go with us, and it's important that we understand ... how they're going to change," explained Cheryl Nickerson, an associate professor at the Center for Infectious Diseases and Vaccinology at Arizona State University.

Nickerson added, in a telephone interview, that learning more about changes in germs has the potential to lead to novel new countermeasures for infectious disease.

She reports the results of the salmonella study in Tuesday's edition of Proceedings of the National Academy of Sciences.

The researchers placed identical strains of salmonella in containers and sent one into space aboard the shuttle, while the second was kept on Earth, under similar temperature conditions to the one in space.

After the shuttle returned, mice were given varying oral doses of the salmonella and then were watched.

After 25 days, 40 percent of the mice given the Earth-bound salmonella were still alive, compared with just 10 percent of those dosed with the germs from space. And the researchers found it took about one-third as much of the space germs to kill half the mice, compared with the germs that had been on Earth.

The researchers found 167 genes had changed in the salmonella that went to space.

Why?

"That's the 64 million dollar question," Nickerson said. "We do not know with 100 percent certainty what the mechanism is of space flight that's inducing these changes."

However, they think it's a force called fluid shear.

"Being cultured in microgravity means the force of the liquid passing over the cells is low." The cells "are responding not to microgravity, but indirectly to microgravity in the low fluid shear effects."

"There are areas in the body which are low shear, such as the gastrointestinal tract, where, obviously, salmonella finds itself," she went on. "So, it's clear this is an environment not just relevant to space flight, but to conditions here on Earth, including in the infected host."

She said it is an example of a response to a changed environment.

"These bugs can sense where they are by changes in their environment. The minute they sense a different environment, they change their genetic machinery so they can survive," she said.

The research was supported by the National Aeronautics and Space Administration, Louisiana Board of Regents, Arizona Proteomics Consortium, National Institute of Environmental Health Sciences, Southwest Environmental Health Sciences Center, National Institutes of Health and the University of Arizona.

Lack of sleep may be deadly, research shows

REUTERS
September 24, 2007 06:39:50 AM PST

People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released on Monday.

Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.

A 17-year analysis of 10,000 government workers showed those who cut their sleeping from seven hours a night to five or less faced a 1.7-fold increased risk in mortality from all causes and more than double the risk of cardiovascular death.

The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.

A third of the population of the UK and over 40 percent in the U.S. regularly sleep less than five hours a night, so it is not a trivial problem," he said in a telephone interview.

he current pressures in society to cut out sleep, in order to squeeze in more, may not be a good idea -- particularly if you go below five hours."

Previous research has highlighted the potential health risks of shift work and disrupted sleep. But the study by Cappuccio and colleagues, which was supported by British government and U.S. funding, is the first to link duration of sleep and mortality rates.

The study looked at sleep patterns of participants aged 35-55 years at two points in their lives -- 1985-88 and 1992-93 -- and then tracked their mortality rates until 2004.

The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.

The correlation with cardiovascular risk in those who slept less in the 1990s than in the 1980s was clear but, curiously, there was also a higher mortality rate in people who increased their sleeping to more than nine hours.

In this case, however, there was no cardiovascular link and Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.

"In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health," he said.

Baloney. Not the unsafe part, that is true. The Soviet design was flawed, just like their economic system. Take that Gene. :loser:

All 104 plants in the US were built in the opposite way of Chernobyl, which was built to produce bombs. You can read about it if you want. Wiki is wrong about so much, that I don't bother to even look at their pages. I don't know what they will say.

http://www.world-nuclear.org/info/chernobyl/inf07.html

http://users.owt.com/smsrpm/Chernobyl/RBMKvsLWR.html

We have had 3 accidents in the US, two of which ended up being near misses in the same plant, Davis-Besse. Three Mile Island melted down for the same reason as other accidents, people. Ours are built to stop the reaction when the cooling system is lost. Davis-Besse had an operator shut down(he wasn't supposed to), but our designs shut the reaction down, and are contained. Three Mile Island had an ongoing problem, and the operators didn't deal with it properly for over two hours. This allowed the reactor to overheat, and led to that melt down.

Anyway, how many coal miners died this week?

Bird Makes Longest Non-Stop Flight

Andrea Thompson
LiveScience Staff Writer
LiveScience.com, 10/01/07

She just flew in from New Zealand and boy are her wings tired.

Early last month, a female Bar-tailed Godwit, a type of shorebird, completed an epic journey from New Zealand to Alaska and back, a trip that included the longest flight ever recorded for a land bird, according to the U.S. Geological Survey (USGS).

The bird logged a flight that lasted for more than eight days and covered a distance of 7,200 miles, the equivalent of flying roundtrip between New York and San Francisco twice. The USGS tracked the migrating bird and its travel mates via satellite.

Bar-tailed Godwits (Limosa lapponica) spend their summers breeding in western and northern Alaska, and in the fall gather on the Alaska Peninsula to make the long flight across the Pacific Ocean to their winter homes in New Zealand and southeastern Australia.

The 18,000-mile (29,000-kilometer) roundtrip journey is the longest known non-stop migration for any shorebird species, though the birds sometimes fly it in several legs.

The conservation status of Bar-tailed Godwits is listed as of High Concern in the United States, mostly because of the birds' low population size (there are only an estimated 100,000 to 150,000 breeding birds in Alaska) and habitat threats to some of their migratory stop-overs in Asia.

New duck-billed dinosaur found in Utah

By BROCK VERGAKIS
Associated Press Writer
10/03/07

The duck-billed dinosaur was one of the world's most imposing herbivores with as many as 800 teeth and a body that could help it knock down trees. Utah scientists have discovered one near the Arizona border that's even more threatening.

"It really is like the Arnold Schwarzenegger of dinosaurs — it's all pumped up," said Scott Sampson, curator of the Utah Museum of Natural History.

The newly named Gryposaurus monumentensis, or hook-beaked lizard from the monument, was discovered in the Grand Staircase-Escalante National Monument in 2002 by a Pennsylvania furniture maker who volunteered to work at the site. Details about the dinosaur, including its name, were published in the Oct. 3 edition of Zoological Journal of the Linnean Society.

At least 30 feet long and 10 feet tall with a robust jaw and thick bones, the 75-million-year-old animal was like a duck-billed dinosaur on steroids, said paleontologist Terry Gates.

"It's basically the Cretaceous version of a weed-whacker," he said. "You have a very formidable herbivore."

Although paleontologists said Wednesday that the dinosaur could eat just about any plant it wanted, scientists still aren't sure what it dined on.

Southern Utah is a rocky desert with few trees today, but it was a much different place 75 million years ago. At the time, North America was divided down the middle by an ocean and southern Utah looked similar to Louisiana, Gates said.

"It's very humid and wet, with lots of ponds and lots of rivers and creeks flowing through it. It was very lush," he said.

The area was a haven for dinosaurs. Gryposaurus monumentensis is one of several new species found in Grand Staircase in recent years.

"I knew this thing would be an important piece of a much larger puzzle we're trying to solve. Grand Staircase is one of the last untapped treasure troves," Sampson said.

The discovery of new species, including Gryposaurus monumentensis, will help scientists understand more about what the earth was like millions of years ago, he said.

Sampson said duck-billed dinosaurs can be found throughout the northwestern part of North America, just like many other animals such as deer. But he said scientists don't find different species of deer close together as they have with the duck-billed dinosaur. The new version of the dinosaur has a smaller skull that allowed it to apply more force to what it was eating.

"By shortening the skull, you can get more power per bite. The shrinking of the skull and the robustness of the jaw and snout all lead me to think this guy was made to eat," Gates said.

However, the duck-billed dinosaur's teeth and size would not have been much of a defense against area predators such as the tyrannosaur. Scientists also aren't sure if the new dinosaur was a loner or traveled in herds for protection because so few skeletal remains have been found.

It's one of several questions scientists are hoping to answer, along with how and why different species of the duck-billed dinosaur developed.

"To find an animal so closely related to something up in Montana and so close by, we would've expected it to be same type of Gryposaurus. The fact it isn't raises some eyebrows," he said.

"This animal, it answered a number of questions. It also poses a number of others."

Secrets of 1957 Sputnik launch revealed

By VLADIMIR ISACHENKOV
Associated Press Writer
Mon Oct 1, 2007

When Sputnik took off 50 years ago, the world gazed at the heavens in awe and apprehension, watching what seemed like the unveiling of a sustained Soviet effort to conquer space and score a stunning Cold War triumph.

But 50 years later, it emerges that the momentous launch was far from being part of a well-planned strategy to demonstrate communist superiority over the West. Instead, the first artificial satellite in space was a spur-of-the-moment gamble driven by the dream of one scientist, whose team scrounged a rocket, slapped together a satellite and persuaded a dubious Kremlin to open the space age.

And that winking light that crowds around the globe gathered to watch in the night sky? Not Sputnik at all, as it turns out, but just the second stage of its booster rocket, according to Boris Chertok, one of the founders of the Soviet space program.

In a series of interviews in recent days with The Associated Press, Chertok and other veterans told the little-known story of how Sputnik was launched, and what an unlikely achievement it turned out to be.

Chertok couldn't whisper a word about the project through much of his lifetime. His name, and that of Sergei Korolyov, the chief scientist, were a state secret. Today, at age 95 and talking to a small group of reporters in Moscow, Chertok can finally give full voice to his pride at the pivotal role he played in the history of space exploration.

"Each of these first rockets was like a beloved woman for us," he said. "We were in love with every rocket, we desperately wanted it to blast off successfully. We would give our hearts and souls to see it flying."

This very rational exuberance, and Korolyov's determination, were the key to Sputnik's success.

So was happenstance.

As described by the former scientists, the world's first orbiter was born out of a very different Soviet program: the frantic development of a rocket capable of striking the United States with a hydrogen bomb.

Because there was no telling how heavy the warhead would be, its R-7 ballistic missile was built with thrust to spare — "much more powerful than anything the Americans had," Georgy Grechko, a rocket engineer and cosmonaut, told AP.

The towering R-7's high thrust and payload capacity, unmatched at the time, just happened to make it the perfect vehicle to launch an object into orbit — something never done before.

Without the looming nuclear threat, Russian scientists say, Sputnik would probably have gotten off the ground much later.

"The key reason behind the emergence of Sputnik was the Cold War atmosphere and our race against the Americans," Chertok said. "The military missile was the main thing we were thinking of at the moment."

When the warhead project hit a snag, Korolyov, the father of the Soviet space program, seized the opportunity.

Korolyov, both visionary scientist and iron-willed manager, pressed the Kremlin to let him launch a satellite. The U.S. was already planning such a move in 1958, he pointed out, as part of the International Geophysical Year.

But while the government gave approval in January 1956, the military brass wanted to keep the missile for the bomb program, Grechko, 76, said in an interview. "They treated the satellite as a toy, a silly fantasy of Korolyov."

The U.S. had its own satellite program, Grechko said. "The Americans proudly called their project 'Vanguard,' but found themselves behind us."

The Soviet Union already had a full-fledged scientific satellite in development, but it would take too long to complete, Korolyov knew. So he ordered his team to quickly sketch a primitive orbiter. It was called PS-1, for "Prosteishiy Sputnik" — the Simplest Satellite.

Grechko, who calculated the trajectory for the first satellite's launch, said he and other young engineers tried to persuade Korolyov to pack Sputnik with some scientific instruments. Korolyov refused, saying there was no time.

"If Korolyov had listened to us and started putting more equipment on board, the Americans could have opened the space era," Grechko said.

The satellite, weighing just 184 pounds, was built in less than three months. Soviet designers built a pressurized sphere of polished aluminum alloy with two radio transmitters and four antennas. An earlier satellite project envisaged a cone shape, but Korolyov preferred the sphere.

"The Earth is a sphere, and its first satellite also must have a spherical shape," Chertok, a longtime deputy of Korolyov, recalled him saying.

Sputnik's surface was polished to perfection to better deflect the sun's rays and avoid overheating.

The launch was first scheduled for Oct. 6. But Korolyov suspected that the U.S. might be planning a launch a day earlier. The KGB was asked to check, and reported turning up nothing.

Korolyov was taking no chances. He immediately canceled some last-minute tests and moved up the launch by two days, to Oct. 4, 1957.

"Better than anyone else Korolyov understood how important it was to open the space era," Grechko said. "The Earth had just one moon for a billion years and suddenly it would have another, artificial moon!"

Soon after blastoff from the arid steppes of the Soviet Republic of Kazakhstan, the satellite sent out what would be the world's most famous beep. But the engineers on the ground didn't immediately grasp its importance.

"At that moment we couldn't fully understand what we had done," Chertok recalled. "We felt ecstatic about it only later, when the entire world ran amok. Only four or five days later did we realize that it was a turning point in the history of civilization."

Immediately after the launch, Korolyov called Soviet leader Nikita Khrushchev to report the success. Khrushchev's son, Sergei, who was alongside his father at the moment, recalled that they listened to the satellite's beep-beep and went to bed.

Sergei Khrushchev said that at first they saw the Sputnik's launch as simply one in a series of Soviet technological achievements, like a new passenger jet or the first atomic power plant.

"All of us — Korolyov's men, people in the government, Khrushchev and myself — saw that as just yet another accomplishment showing that the Soviet economy and science were on the right track," the younger Khrushchev, now a senior fellow at Brown University's Watson Institute for International Studies, said in a telephone interview.

The first official Soviet report of Sputnik's launch was brief and buried deep in Pravda, the Communist Party daily. Only two days later did it offer a banner headline, quoting the avalanche of foreign praise.

Pravda also published a description of Sputnik's orbit to help people watch it pass. The article failed to mention that the light seen moving across the sky was the spent booster rocket's second stage, which was in roughly same orbit, Chertok said.

The tiny orbiter was invisible to the naked eye.

Excited by the global furor, Khrushchev ordered Korolyov immediately to launch a new satellite, this time, to mark the Nov. 7 anniversary of the 1917 Bolshevik Revolution.

"We didn't believe that you would outpace the Americans with your satellite, but you did it. Now you should launch something new by Nov. 7," Korolyov quoted Khrushchev telling him, according to Grechko.

Working round-the-clock, Korolyov and his team built another spacecraft in less than a month. On Nov. 3, they launched Sputnik 2, which weighed 1,118 pounds. It carried the world's first living payload, a mongrel dog named Laika, in its tiny pressurized cabin.

The dog died of the heat after a week, drawing protests from animal-lovers. But the flight proved that a living being could survive in space, paving the way for human flight.

The first Sputnik beeped for three weeks and spent about three months in orbit before burning up in the atmosphere. It circled Earth more than 1,400 times, at just under 100 minutes an orbit.

For Korolyov there was bitterness as well as triumph. He was never mentioned in any contemporary accounts of the launch, and his key role was known to only a few officials and space designers.

Leonid Sedov, a member of the Soviet Academy of Sciences with no connection to space program, was erroneously touted in the West as the Father of Sputnik. Korolyov, meanwhile, was only allowed to publish his non-sensitive research under the pseudonym "Professor K. Sergeyev."

Khrushchev rejected the Nobel committee's offer to nominate Korolyov for a prize, insisting that it was the achievement of "the entire Soviet people."

Sergei Khrushchev said his father thought singling out Korolyov would anger other rocket designers and hamper the missile and space programs.

"These people were like actors; they would all have been madly jealous at Korolyov," he said. "I think my father's decision was psychologically correct. But, of course, Sergei Korolyov felt deeply hurt."

Korolyov's daughter, Natalia, recalled in a book that the veil of secrecy vexed her father. "We are like miners — we work underground," she recalls him saying. "No one sees or hears us."

The Soviet Union and the rest of the world learned Korolyov's name only after his death in 1966. Today his Moscow home, where Chertok met reporters, is a museum in the chief scientist's honor.

Chertok was permitted to travel abroad only in the late 1980s, after Soviet leader Mikhail Gorbachev liberalized the Soviet Union.

The surviving leaders of the space program are no longer anonymous or silent, and revel in the accolades so long denied them.

"The rivalry in space, even though it had military reasons, has pushed the mankind forward," said Valery Korzun, a cosmonaut who serves as a deputy chief of the Star City cosmonaut training center. "Our achievements today are rooted in that competition."

In the end, it was the Americans who won the race to the moon, nearly 12 years later. Khrushchev wasn't interested in getting there, his son says, and the effort made under his successor, Leonid Brezhnev, was underfunded and badly hampered by rifts between Korolyov and other designers.

"We wouldn't have been the first on the moon anyway," Grechko said. "We lost the race because our electronics industry was inferior."

Today, even as Sputnik recedes into the history books, its memory still exercises a powerful grip. In August, when a Russian flag was planted on the sea bed at the North Pole, the Kremlin compared it to Neil Armstrong stepping on the moon — an indication, perhaps, of how much Russians still treasure that first victory in space.
