Conspiracy theorists see Antarctica UFO

A video taken of the Antarctic research station Neumayer-Station III appears to show what some are calling a UFO over the South Pole.

The video posted to YouTube seems to show a round, blurry object floating above the station on Aug. 10. Speculation has run rampant, with conspiracy theorists and UFO buffs swapping explanations ranging from government collaboration with aliens to a top-secret test of some new cutting-edge secret weapon.

While a definitive explanation has not been found, several elements suggest a prosaic answer. The supposed UFO appears more or less directly over the research station; it also appears to be nearly perfectly round and about the right size for a balloon. Neumayer-Station III, a scientific research station, carries out tests and experiments in a wide variety of areas, including geophysics, meteorology and atmospheric chemistry. Weather balloons are used extensively to study and sample the atmosphere at different times and altitudes above Antarctica.

One UFO buff admitted that most of the evidence suggested it was indeed a balloon, except for one mysterious fact: "none could explain why the object appeared in just a few frames." It's true that the object appears in only a few frames of the footage. However this becomes much less mysterious when you realize that the original video has been sped up. That's what happens in time-lapse photography: objects that are not stationary for long periods of time (people, vehicles, animals, clouds, etc.) only appear in a few frames ? depending of course on the frame rate of the video and how fast they move. There's nothing mysterious about it. [ UFO Quiz: What's Really Out There? ]

If it were a balloon that had been put aloft for hours, it would have been visible for a longer duration than seen in the video. On the other hand, not all experiments using balloons necessarily last for hours; some may take only a few minutes. It's also possible that someone at the station was merely conducting a routine equipment test in preparation for an upcoming experiment or sampling: The balloon went up, everything worked perfectly, so it came back down.

Though the "Neumayer UFO" is being discussed on various UFO and conspiracy theory websites, there's a glaring contradiction in suggesting it's evidence of extraterrestrials. If it is indeed a spacecraft instead of a balloon or some other mundane object, why would the government ? which is routinely accused of going to extraordinary lengths to cover up all evidence of aliens ? intentionally release the video to the public?

Unlike an Air Force base where people live and work nearby and can usually photograph or videotape what's in the skies above at will, Neumayer-Station III in Antarctica is essentially inaccessible to the public ? except in limited ways such as a Web cam that the government has exclusive access and control over. Did this somehow get past the global UFO censors?

Conspiracy-minded people will always search for, and often find, anomalies, things that they don't understand or believe to be odd or unusual for some reason. For some people any ambiguous light or object in the sky they don't recognize can be turned into a possible UFO sighting.

Astronomers release biggest ever 3-D map of the universe (+video)

Using data from the Sloan Digital Sky Survey III, the 3-D map contains more than a million galaxies.?

By SPACE.com Staff / August 9, 2012

This still from an animated fly-through of the new universe map created by the Sloan Digital Sky Survey-III shows the positions of galaxies mapped in 3D space.

The largest 3D map yet of the universe's huge galaxies and bright black holes may serve as a springboard toward solving some of astronomy's greatest mysteries, its creators say.

The map, which was released Wednesday (Aug. 8), uses new data to reveal the locations of more than a million galaxies over a total volume of 70 billion cubic light-years. (A light-year is the distance light travels in one year ? about 6 trillion miles, or 10 trillion kilometers.)

David Schlegel of Lawrence Berkeley National Laboratory in California said this kind of atlas could help scientists get to the bottom of perplexing mysteries such as the invisible, untouchable?dark matter?and dark energy that seem to be rampant in space.

"Dark matter and dark energy are two of the greatest mysteries of our time," Schlegel said in a statement issued with the map's release. "We hope that our?new map of the universe??can help someone solve the mystery."

The new data come from the?Sloan Digital Sky Survey III?(SDSS-III), and they include measurements from the ongoing SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS), which calculates the distances to galaxies as far as 6 billion light-years away and humongous black holes that lie up to 12 billion light-years from Earth.

The SDSS-III project publically released a large amount of its data, including the map, for use by astronomers around the world in their own studies.

"Our goal is to create a catalog that will be used long after we are done," said Michael Blanton of New York University, who led the team that prepared the data release.

The release contains photos of 200 million galaxies and spectra (measurements where an object's light is split into its constituent wavelengths) of 1.35 million galaxies.

"We want to map the largest volume of the universe yet, and to use that map to understand how the expansion of the universe is accelerating," said Daniel Eisenstein of the Harvard-Smithsonian Center for Astrophysics, the director of SDSS-III.

Scientists think the prevalence of dark energy in the universe is the force causing space to accelerate in its expansion to a greater and greater volume.

Human and Neanderthal interbreeding questioned

It was the discovery that challenged what it is to be human. The Neanderthal genome revealed that our extinct cousin's genes live on in many modern humans, implying that the two species interbred. But a controversial new study casts doubt on those claims of interspecies hanky-panky.

In 2010, Svante P??bo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues sequenced the Neanderthal genome. Their analysis concluded that many modern humans carry a few Neanderthal genes. Only native Africans lack the Neanderthal genes, because Neanderthals did not live in Africa.

Right from the start, there was a problem. Neanderthals and modern humans ultimately evolved from the same ancestral population, so any genes shared by the two species might simply have been inherited from this common ancestor.

"We were very upfront in our papers that this was a possibility," says P??bo's colleague David Reich of the Harvard Medical School in Boston.

Drifted apart

Andrea Manica and Anders Eriksson at the University of Cambridge have now built a model to demonstrate a non-interbreeding explanation for the 2010 result.

They began with an ancestral hominin population throughout Africa and Europe. Because of their regional proximity, the hominins in Europe had more genes in common with those of northern Africa than those of southern Africa.

Africa and Europe then became genetically isolated from one another, perhaps triggered by changing climates, says Manica. This allowed the Europeans to evolve into Neanderthals and the Africans to evolve into modern humans. Crucially, though, the modern humans in northern Africa retained genetic similarities with Neanderthals that the southern Africans lacked. Northern Africans ultimately moved into Europe ? but they didn't need to interbreed with Neanderthals to share some genes in common with them (see diagram).

"You cannot prove there was never any hybridisation," says Manica. "But none of the evidence [for hybridisation] is convincing."

Shuffled up

Reich and P??bo disagree with the new formulation. They say recent analyses actually firm up the case for interbreeding. Most tellingly, Reich and his colleagues have an upcoming paper in PLoS Genetics that suggests non-Africans have shared genes in common with Neanderthals for only a few tens of thousands of years. If correct, this means these genes cannot predate the origin of Neanderthals, around 320,000 years ago.

His team examined the genomes of modern Europeans to work out how much the Neanderthal-like genes had been shuffled around. The greater the degree of shuffling, the longer they must have been a part of the genome. He found that there was limited gene movement, implying that they entered the European genome between 65,000 and 47,000 years ago ? around the time modern humans left Africa.

The evidence for interbreeding is growing, but Manica and Eriksson's study shows we should still consider the alternatives, says Joshua Akey of the University of Washington in Seattle.

US destroyer collides with oil tanker in Gulf

Jonathan Sunderman / AFP - Getty Images

A handout picture released by the U.S. Navy shows the damaged destroyer USS Porter following a collision with a bulk oil tanker in the Strait of Hormuz on Sunday.

By NBC News wire services

An oil tanker collided with a U.S. Navy destroyer near the Strait of Hormuz on Sunday but no one was hurt and shipping traffic in the waterway, through which 40 percent of the world's seaborne oil exports pass, was not affected, officials said.?

"Both vessels are okay and the Strait of Hormuz is not closed, and business is as usual there," an Oman coast guard official told Reuters, declining to be named under briefing rules.?

The collision nevertheless left a gaping hole in the starboard side of USS Porter, a?guided-missile destroyer suffered,?but no one was injured on either vessel, the U.S. Navy said in a statement. The collision with the Panamanian-flagged bulk oil tanker M/V Otowasan occurred at approximately 1 a.m. local time.?


The cause of the incident is under investigation, the Navy said, adding that there were no reports of spills or leakages from either the USS Porter or the Otowasan.?

A collision between an oil tanker and a U.S. Navy missile destroyer in the Strait of Hormuz left the Navy ship with a gaping hole in its hull. NBC's Lester Holt reports.

US won't allow Iran to shut down Strait of Hormuz, Panetta vows

The USS Porter is on a scheduled deployment to the U.S. 5th Fleet, which is based in Bahrain.?

The Strait of Hormuz, located at the mouth of the Persian Gulf, is where one-fifth of the world's oil is routed. Tensions have risen there over Iran's threats to block tanker traffic in retaliation for tighter sanctions by the West.?

Three years ago, The USS Hartford, a nuclear-powered submarine based in Groton, Conn., collided in the Strait with the USS New Orleans, a San Diego-based amphibious ship.?

The New Orleans' fuel tank was ruptured and 15 sailors on the Hartford sustained minor injuries. The collision caused $2.3 million in damage to the New Orleans, and the cost so far of repairs to the Hartford is $102.6 million.?

A Navy ship opened fire on a boat that appeared to pose a threat, and a there is a new UAE oil pipeline that bypasses the Strait of Hormuz, with CNBC's Tyler Mathisen and Sharon Epperson.

Insight: The greatest Olympian and his coach

LONDON (Reuters) - When a teenage Michael Phelps started splashing the girls at the end of a particularly tough training session, his coach Bob Bowman tried to discipline him.

"I said, 'you should be very tired, that's the hardest practice you've ever done,'" the coach recalled.

"I'll never forget. He looked me straight in the eye and said 'I don't get tired.' So I made that my life goal, to see if I could accomplish that."

Twenty-two Olympic medals later - including 18 golds - the greatest Olympian finally retired from competitive swimming at last week's London Olympics. Much more than raw energy drove the boy from Baltimore through race after lung-bursting race.

To understand Michael Phelps, you also have to talk to the man with a psychology degree who trained him, who knew exactly when and how to rile him, who drove Phelps almost to the point of rebellion.

Bowman, 47, is quietly spoken, white haired and bespectacled. He has none of the air of the poolside bully. But that's one of the roles he played.

"I've always tried to find ways to give him adversity in either meets or practice and have him overcome it," Bowman has said.

"The higher the level of pressure, the better Michael performs. As expectations rise, he becomes more relaxed... That's what makes him the greatest."

A FIDGETY BOY

Phelps didn't take easily to swimming as a five-year-old.

"I was afraid of the water at first, I didn't want to put my face under," he said. "I just didn't like the feeling."

Born on June 30 1985, Michael was the youngest of three children. His father, Fred, had been a college football player who once tried out for the Washington Redskins. His mother, Debbie, was a schoolteacher who became a Middle School principal.

In elementary school, Phelps was diagnosed with attention-deficit hyperactivity disorder - he used to take medication on school days. He was bullied. His parents divorced when he was nine and his mother, who raised him, encouraged him to follow his accomplished older sisters into swimming.

It gave him a focus. By age 10, he broke his first national age record. He started training with Bowman the year after that.

Bowman says that from the moment he met Phelps he knew he had discovered the once-in-a-lifetime swimmer every coach dreams about.

"When I went home that night I couldn't sleep I was so excited, but of course I didn't tell him that."

Phelps was the youngest and would start practice at the back of the line of swimmers doing laps in the pool, Bowman recalled. But by the end of the training session, "I saw a little cap moving up forward to the front of the line with each repeat swim.

"It was so remarkable, I'd never seen anything like it."

He asked the boy to pick his three favorite races, nominate the times he wanted to achieve for each and make that his goal for the year.

"He was just 11 but six months later he swam those exact times, to the one-hundredth of a second," Bowman said. "I don't know how that's possible, but it's true."

SWIMMING BLIND

The excitement was tempered by the realization that Bowman himself needed to improve his own coaching skills and come up with new ways to get the best out of the young athlete.

"I wanted to impress them and think I was tough, I gave them an extremely difficult training program." He started by increasing the workload. Phelps coped with every task.

When Phelps was 13, Bowman made him swim 21 races in three days.

For good measure, when the boy was swimming at one of his first national junior meets, he let him race without goggles.

Bowman noticed Phelps had left his goggles behind just before he walked out to the blocks. To swim without them would make his eyes sting red with chlorine or he would have to close them.

"I could have taken the goggles to him but I decided to keep them and see what he could do," Bowman said. Phelps won the race without the goggles, and though Bowman didn't know it at the time, it was to prove a masterstroke.

In Beijing in 2008, Phelps dived in for the 200 meters butterfly and his goggles filled with water. Unperturbed, he swam blind to a new world record.

FEET LIKE PADDLES

Outside the pool, Phelps found an idol and the lure of fame. He was 15 when he became the youngest American male swimmer to make the Olympics since 1932 and when he arrived in Sydney for the 2000 Games, he entered a new world.

The first billboard he saw was of a swimmer. Swimming was on the front and back of every newspaper and the lead item on the TV news. It was the biggest show in town, and the star attraction was a teenage boy, but it wasn't Michael Phelps.

Shy and unassuming, Ian Thorpe had a seductive technique that made swimming look easy. Propelled by huge feet and hands the size of saucers, he won his first title when he was just 15 and set about demolishing world records in his two pet events, the 200 and 400 meters freestyle.

Thorpe won three gold and two silver medals in Sydney: Phelps hardly created a ripple and the disappointment at not winning a medal made him redouble his efforts. "I was hard on myself for not achieving it."

It was at the 2003 world championships in Barcelona that Phelps first replaced Thorpe as the king of the pool, winning four gold medals and setting five individual world records.

Still just 19 at the time, he had grown into his 1.93 meter (6ft 4 in) frame. Most people have an armspan equivalent to their height, but Phelps' reach is about three inches longer. His size 14 feet work like paddles and his double-jointed elbows, knees and ankles add flexibility and propulsion.

PUSHING THE BUTTONS

Working with Phelps after his parents' divorce, Bowman taught him not only discipline but also how to do up his tie before his first school dance, and how to drive.

Like father and son, the two argued constantly, even about music: Phelps is into hip-hop where Bowman favors orchestral pieces.

Bowman spends his spare time playing the piano, and breeding and racing horses. He once considered naming a horse after Phelps, he said, but on consideration decided that would be unwise - it would put too much pressure on the horse.

Sometimes he would play mind games with the young swimmer. Before a Beijing race, Phelps recalled, "Bob said to me it would be good if I lost. When he said that, I was fired up, I said 'I'm going to go for it.'"

And Bowman has goaded Phelps about rivals. In Beijing, he made sure the swimmer knew before a race about comments made by Serbia's Milorad Cavic, the Serbian who had said it would be bad for the sport if the American won eight golds in Beijing.

"I brought it up on the way to breakfast," Bowman said. "I wasn't going to, but I threw it out there."

Phelps clawed his way from a seemingly hopeless position to beat Cavic by one-hundredth of a second, winning his seventh gold and equaling the record set by Mark Spitz at Munich in 1972. With the help of a relay he went on to make it eight - a feat that brought him a $1 million prize from his sponsors.

"I wanted to do something no one else had done in swimming," said Phelps. "I'd rather be the first Michael Phelps than the next somebody else."

He spent the $1 million prize establishing a foundation to help disadvantaged children learn how to swim.

SHEER WILLPOWER

The day after his Beijing triumph, Phelps' head was spinning. "I don't know where I'm going or what I'm doing, I'm just along for the ride," he said.

Within minutes of receiving his gold medal, he had taken a call from U.S. President George W. Bush, who told him to make sure he hugged his mother. He received nearly 5,000 messages on his BlackBerry but didn't have the energy to read them all.

He spent the night having a quiet dinner with his mother and sisters. He ordered a cheeseburger and did not drink a drop of champagne or any alcohol.

Phelps realized that now the only way was down. A whole new direction.

He declared he would compete at London but ruled out an attempt at nine gold medals or even eight. He started to skip training and put on weight, making regular trips to Las Vegas and hanging out with college pals.

He partied too hard. The newspapers published photographs of him inhaling from a glass pipe used for smoking marijuana. Phelps apologized and was suspended for three months.

His medal tallies were getting lower. At the 2011 world championships, he was beaten by countryman Ryan Lochte in two races.

The losses proved the jolt he needed. For the first time since Beijing, he could see a challenge.

Each morning, he got up before dawn, packed his swimming trunks, goggles and towel and headed to the pool. He returned each afternoon, logging up to 70 km (43 miles) a week in laps.

He was not the same swimmer as in Beijing, but London was to be an everlasting reminder of his determination.

After a poor start, he fought back. He anchored America to gold in the 200 meters freestyle relay final to claim his 19th Olympic medal, overtaking Soviet gymnast Larisa Latynina's overall total of 18, which had stood unchallenged for nearly half a century.

He was not quite finished. He beat Lochte in the 200 meters individual medley to become the first male swimmer to win the same individual event at three Olympics. Then, through sheer force of will, he won the 100 butterfly after lying seventh at the turn.

He finished his career with 18 gold medals, six from Athens, eight from Beijing and four from London. When he stood on the podium for the last time, his eyes filled with tears.

"I said 'I love you' first, we hugged," said Bowman. He said 'We did it,', we smiled and I said 'yes we did' and that was it. He's done all he can do here."

Romney, Ryan hit the road in an energized campaign

HIGH POINT, North Carolina (Reuters) - Republican Mitt Romney's presidential campaign took on a celebratory tone on Sunday, as Romney and his new vice presidential running mate, Paul Ryan, basked in the support of cheering crowds in North Carolina.

Thousands of people lined a highway in High Point to greet Romney and Ryan, who stopped to shake hands and exchange high-fives with some of them. Another 1,300 packed into a stifling hot furniture warehouse for a rally with the Republican candidates.

"We can turn this around," said Ryan, 42, who was speaking of the economy and budget but might as well have been referring to the campaign of Romney, who has trailed Democratic President Barack Obama in recent polls.

"We can do this. We can get this country back on track," Ryan told the cheering crowd. "We can get our people back to work. We can get our debt paid off so we can give our children a better standard of life."

Romney added that he and Ryan have "a long road ahead of us, but this is day two to reclaim America's progress."

The November 6 election is more than two months away, but the rally had the intensity of a typical late-October campaign event. It showed how Romney's selection of the Wisconsin congressman as his running mate has injected new energy into a campaign that had struggled to move beyond Democrats' efforts to cast Romney as a wealthy former private equity executive who cannot relate to middle-class Americans.

Hours earlier in Virginia, where Romney had introduced him as the No. 2 on the Republican ticket on Saturday, Ryan, the chairman of the House of Representatives Budget Committee, told reporters that being thrust into the presidential campaign was "very exciting. We're going to win this campaign. We've got the wind behind us."

Romney, 65, seemed relieved to have a sidekick to end what he has called the "two against one" dynamic of the race, with Obama and Vice President Joe Biden on one side and Romney on the other.

"It's a far more compelling dynamic than just being out there on my own," Romney said late Saturday.

But it also was evident that Romney's selection of Ryan - who is known for his sweeping budget plan to reduce government spending and debt by trimming taxes and revamping Medicare and other social programs - is going to raise a series of hurdles for his campaign as it sprints toward election day.

In choosing Ryan, Romney is attaching himself to Ryan's controversial budget plan, which has been blasted by Democrats who say it would dismantle popular social programs that help the elderly and the poor.

Ryan's selection also suggested that Romney is tackling a prickly task during an intense, nasty and likely close race for the White House. His is asking Americans to consider tough questions about the future of Medicare, the government-backed health insurance program for the elderly, and a range of other programs plagued by runaway spending.

SEEKING A NATIONAL DEBATE?

In previous elections, candidates who have sought a not-so-popular conversation with American voters have run into problems.

In 1984, for example, Democrat Walter Mondale emphasized the need for higher taxes and was swamped at the ballot box as voters re-elected Republican Ronald Reagan.

If Romney's campaign wants to foster a national debate over social programs and government entitlements, the big challenge will be doing so under the white-hot glow of the final weeks of a presidential campaign that so far has been defined by sound-bite messaging and out-of-context attacks by both sides.

On Sunday, Republican National Committee Chairman Reince Priebus cast Romney's campaign as the one being honest with Americans about the nation's fiscal future and said Obama's team is more interested in attacking Romney.

Selecting Ryan shows that Romney "has the leadership and courage to present to the American people a real contrast and a real debate that the American people deserve," Priebus said on NBC's "Meet the Press."

Even so, Romney's campaign stressed that Romney would propose his own fiscal plan, suggesting that it did not want the former Massachusetts governor to be tied to everything in Ryan's budget.

"The thing you have to remember about these campaigns is that Governor Romney is at the top of the ticket, and that Governor Romney's vision for the country is something that congressman Ryan supports," said Romney spokesman Kevin Madden.

DEMOCRATS TAKE AIM

Democrats' efforts to cast Ryan - and, by extension, Romney - as a threat to Medicare could be key in the election.

Ryan's plan calls for an end to the guaranteed benefit in Medicare and replaces it with a system that would give vouchers to recipients to pay for health insurance.

The risk in such a plan is that if healthcare costs rise faster than the value of the vouchers, seniors would have to pay the difference.

Obama's senior campaign adviser David Axelrod said on "Meet the Press" that the Medicare changes supported by Ryan would put the healthcare program, which polls indicate most Americans do not want changed, into a "death spiral."

Independent Democratic groups have been more dramatic in their criticism.

A video ad from 2011 - made when Ryan first offered his proposals on Medicare but now getting a new life online with Romney's selection of Ryan - shows a man in a suit who resembles Ryan pushing an elderly woman in a wheelchair over a cliff, while "America the Beautiful" plays.

A message then pops up at the end of the ad: "Is America beautiful without Medicare? Ask Paul Ryan and his friends in Congress."

Romney rejected the notion that Ryan's plan would kill Medicare.

Ryan "has a plan ... to make sure we can save Medicare," Romney said. "And guess what, he's one of two sponsors - and guess what, the other is a leading Democrat," a reference to Oregon Senator Ron Wyden.

Wyden, however, has disagreed with Romney's characterization of his work on the Medicare issue, saying that he has voted against Medicare changes proposed in Ryan's budget.

Wyden told The Huffington Post that he merely had worked on a "policy paper" with Ryan that was designed to "start a conversation about how Democrats and Republicans might work together to uphold the Medicare guarantee."
