VANCOUVER, British Columbia – After nearly three weeks, the Winter Olympics are over, and the world’s obsession with the Games will go on hold until the summer of 2012, when the circus will hit London.

It’s been eventful trying to deliver the news, with varying degrees of success: I investigated whether the sport of curling was doomed due to the world’s supply of granite. I asked a man from the Netherlands why he skated in a skeleton outfit. I tried to find Swedish women to talk about Tiger Woods. I met athletes who deserve at least a sliver of the attention Tiger’s mistresses recei

A similar quake in Chile in 1960 created a tsunami that killed about 140 people in Japan. The same surge hit Hawaii and devastated downtown Hilo, on the Big Island, killing 61 residents and wiping out more than 500 homes and businesses.

“If you give too many warnings and none of them materialize, then you lose your credibility,” Wang said. “That’s something that we have to deal with and we have to improve.”

Despite some of the panic in Hawaii, public officials called the evacuation “perfect” and said it was a good test case that proved the system worked.

Chaos was at a minimum as people heeded evacuation orders and roads were free of the gridlock that can paralyze a region before a disaster. The smooth response occurred largely because the state had so long to prepare; Hawaii is nearly 7,000 miles from where the quake hit, and it took 15 hours for the tsunami to arrive.

“I hope everyone learned from this for next time, and there will be a next time,” said Gerard Fryer, a geophysicist for the warning center.

The science of predicting tsunamis is difficult, given the vast size of the ocean and the volatile forces at work miles below the surface.

Scientists use an earthquake’s magnitude and location as the basis for their predictions and then refine it constantly with data from more than 30 deep-water sensors stationed across the Pacific as the shock wave sweeps across the ocean floor.

The sensors, located at 15,000 to 20,000 feet beneath the surface, measure the weight of the water and beam it to buoys floating on the surface. Scientists then use the data to calculate the tsunami’s wave height in the open ocean as it progresses toward shallower waters.

Coastal inundation models based on topographic mapping add another layer of analysis, helping scientists make assumptions about how the surge will behave in shallower waters and how it might affect shoreline communities.

“There are all sorts of assumptions that we make in trying to figure out how big the waves are going to be. If we can avoid some of those assumptions, maybe we can do a better job,” said Fryer.

“If this event happened tomorrow, even with this knowledge, we would be forced to do the exact same thing.”

Those models could be more accurate if scientists had more deep-water sensors and could build coastal inundation models for vast parts of the Pacific Rim where the topography hasn’t yet been well-surveyed, Wang said.

Because complete data doesn’t exist for every coastal area, scientists must play it safe in their wave predictions, he said.

“Even for Hawaii, we only have a forecast for less than 10 locations, we don’t have inundation models for every coastal point in Hawaii and it’s the same story for the U.S. mainland,” Wang said. “We’ve got to be a little conservative. One point doesn’t tell you that’s going to be the maximum everywhere else.”

In areas where inundation models exist, scientists’ predictions were close to accurate, Wang said.

Residents and tourists alike in Hawaii said they weren’t bothered by the evacuation and supported the scientists’ actions — even though the waves never showed up.

Eugene Okamoto, 33, said he came to Honolulu from Hilo to visit some tourist attractions with his father and was disappointed the two had to cancel their plans because of the evacuation orders.

But Okamoto said his family understands the tsunami threat better than most because some of his relatives lived through the tidal surge in 1960. They remember how the water was sucked down the beach moments before the wave hit.

“My uncle was on the top floor when all the water washed away and all the kids ran out to grab the fish and before they could get back, the wave came. He was way up top, he saw all his friends get washed away and none of them were found, ever,” Okamoto said, as he sat with his father in a hotel lobby. “They did the right thing.

PITTSBURGH – With her boyfriend in severe abdominal pain, Sharon Edge called 911 for an ambulance in the early morning hours of Feb. 6. Heavy snow was falling — so heavy it would all but bring the city to a standstill — and Curtis Mitchell needed to go to a hospital.

“Help is on the way,” the operator said.

It never arrived.

Nearly 30 hours later — and 10 calls from the couple to 911, four 911 calls to them and at least a dozen calls between 911 and paramedics — Curtis Mitchell died at his home. His electricity knocked out, his heat long off, the 50-year-old former steelworker waited, huddled beneath blankets on his sofa.

“I’m very angry, because I feel they didn’t do their job like they supposed to,” said Edge, 51. “My man would still be living if they’da did they job like they was supposed to … They took somebody that I love away.”

Mitchell, on disability for depression, had a history of pancreatitis, an inflammation of the pancreas, Edge said, and had spent nine days in a hospital in late January. He had been home about a week when he was overcome with pain. Autopsy results are pending, awaiting toxicology test results, authorities said.

Now Pittsburgh officials have ordered an investigation and reforms of the city’s emergency services system as Mitchell’s case highlighted key shortcomings:

• Details of Mitchell’s calls weren’t passed on from one 911 operator to another as shifts changed, so each call was treated as a new incident.

• Twice, ambulances were as close as a quarter-mile from Mitchell’s home but drivers said deep snow prevented the vehicles from crossing a small bridge over railroad tracks to reach him. Mitchell was told each time he’d have to walk through the snow to the ambulances; in neither case did paramedics walk to get him.

• Once, an ambulance made it across the bridge and was at the opposite end of the block on the narrow street where the couple lived — a little more than a football field’s length. Again, paramedics didn’t try to walk.

“We failed this person,” said Michael Huss, the city’s public safety director.

To be sure, Mitchell’s ordeal unfolded as the storm dumped nearly two feet of snow on Pittsburgh; the 911 system was swamped with more than twice as many calls as usual and overall emergency response was hampered.

Regardless of how deep the snow was, Huss said it was unacceptable that paramedics didn’t walk to help Mitchell. If they had, Huss believes Mitchell may have survived.

“… You get out of that damn truck and you walk to the residence,” Huss said. “That’s what needed to happen. We could have carried him out.”

The six paramedics on the three ambulances could be disciplined, Huss said. He declined to say what that might be.

Paramedics or firefighters will now be required to go to a caller’s door.

“Everyone needs to get a response,” Huss said Thursday.

That Mitchell died waiting to get to the hospital is a cruel coincidence.

Edge and Mitchell met eight years ago in an emergency room. Both were getting their medications under control for their mental illnesses, she said. He was being treated for depression; she has bipolar disorder.

“We’ve been stuck together ever since, like glue,” Edge said.

Several years ago, they moved into a small red brick rowhouse in Hazelwood, the riverside neighborhood that was home to Pittsburgh’s last working steel mill, which shut down a dozen years ago.

Sitting on the tan and blue fabric sofa where Mitchell died, Edge described him.

He enjoyed watching TV, particularly westerns. They hoped to get married by a justice of the peace in April, then celebrate with a little party.

“He did for his friends,” she said. “He looked out for other people when they needed stuff. He was there to help.”

They didn’t have a car. During the storm, a neighbor offered to drive them to a hospital but he couldn’t get his car shoveled out.

Edge is a little sketchy on details of Mitchell’s worsening condition and death. Then again, she didn’t think she’d need to relive them. She thought they first called 911 on the night of Feb. 5, but records indicate the first call was made about 2 a.m. on Feb 6. Sometime Friday night, the storm knocked out their power and the couple sought warmth under blankets as the house got colder.

Edge said Mitchell had begun to feel stomach pains during the week, but he tried to deal with it. By Friday morning, he woke up in pain. Still, he tried to manage with medication, she said.

A review of the 911 calls by the Associated Press shows no anger in Mitchell’s or Edge’s voices. There was no screaming. Conversations with operators were cordial and the couple seemed to understand the difficulties the snow posed.

Still, Mitchell and Edge let them know he was in pain.

“My stomach man, it’s real messed up. It’s killing me,” he tells a 911 operator about 11:15 a.m. on Feb. 6.

About 8 p.m. that night — in the eighth call to 911 — Edge tells an operator: “My boyfriend called for an ambulance. He’s in a lot of pain and we’ve been waiting for a couple hours now.”

At one point, Mitchell can be heard exclaiming “Oh man, what?” when Edge relayed to him that they would have to walk to the ambulance because of the snow. It was not clear when that conversation took place.

In all, three ambulances were dispatched at separate times. In each case, Mitchell was told he’d have to walk to them — and he canceled the calls.

As the hours went by, Mitchell’s pain intensified and he began to have shortness of breath. Because he complained of abdominal pain, which is generally not considered life-threatening, he was initially ranked as a medium priority. About 11:20 a.m. Saturday, his priority level was upgraded, but not as an emergency.

Mitchell tried to sleep. He took his prescriptions — oxycodone for pain and sleeping pills for his insomnia. Edge gave him the medication and closely followed the dosage, she said.

“All that time, he was dying and I didn’t even know it,” Edge said.

Shortly before 8 a.m. on Feb. 7, Edge made her last 911 call.

“I think my husband’s dead. Oh God, oh God,” she sobbed.

The 911 operator told Edge to calm down and asked for the address and phone number.

“I’ve been trying to get an ambulance here for three days. He’s been having stomach pains,” Edge said.

The operator talked Edge through a check to see if Mitchell was breathing. Try to get him onto the floor on his back, the operator said.

But Mitchell’s body was cold. Edge couldn’t wake him.

“Oh God, he can’t leave me … Curtis? Curtis?” Edge said, struggling to move him.

The operator assured Edge that paramedics were on the way.

“He’s dead,” Edge said.

“No, no, no. You’re going to stay with me,” the operator said, continuing the checks on Mitchell.

Finally, someone came to the door.

“Who is it?” asked Edge. “Is it the medics?”

“Yes.”

“All right,” said the operator. “You did a good job. I’m going to hang up now. Let them in. Good bye.”

The snow had long since stopped falling. It took firefighters two minutes from being dispatched to reach the couple’s home.

They checked for a pulse, but it was too late.

“They said he was gone,” Edge said.

It would be five more hours before workers from the medical examiner’s office came for Mitchell’s body.

A police officer waited with her. Edge sat on the sofa with the body.

“I kissed and hugged him,” she said of Mitchell. “But it was all I could do.”

CONCORD, N.H. – Frustration turned to resignation Saturday for hundreds of thousands of people in the Northeast struggling to survive another day waiting for utility crews to restore electricity after powerful storms socked the region with heavy snow, rain and hurricane-force winds.

The region was left to deal with the fallout of gusting winds that created near-blizzard conditions this week in what was the third strong storm this month for some areas. Parts of New York got more than 2 feet of snow while some areas of coastal New England were drenched with flooding rains.

One man was killed by a falling snow-laden tree branch in Central Park in New York City, and two people in Candia, N.H., died in a house fire caused by improperly using a propane heater to stay warm, fire officials said.

The highest wind reported from the storm was 91 mph off the coast of Portsmouth, N.H. — well above hurricane force of 74 mph. Gusts also hit 60 mph or more from the mountains of West Virginia to New York’s Long Island and Massachusetts.

Frustration was beginning to show on Charlotte Letteney’s face Saturday at Concord High School, one of 24 shelters in New Hampshire. Letteney, 64, of Allenstown, arrived Friday night with her 66-year-old husband, who is a paraplegic, two granddaughters, her grandson-in-law and 6-month-old great-grandson.

The family left their mobile home when the temperature dropped to 46 degrees and Letteney’s hands had gone numb, leaving behind four parrots in covered cages and a couple of days’ worth of food for their dog, Bosco. They have no car — a city van brought them to the shelter — and no way to get home to feed the animals or to let the dog out.

“He’ll go out in the kitchen, and I’ll have to sterilize my floor,” Letteney said.

The Letteneys are among more than 1 million customers across the Northeast who lost power because of the storm, and as of Saturday afternoon more than half of them were still without electricity. New Hampshire’s electrical grid was the hardest hit, with more than a quarter-million customers still without power. New York had more than 160,000 outages and Maine about 67,000.

Some residents were warned they’ll be without electricity for up to a week, as uprooted trees and fallen utility poles hindered utility crews.

Bow, N.H., Assistant Fire Chief Dick Pistey compared the situation two years ago during a powerful ice storm when ice quickly coated trees, bringing down tree limbs and power lines, leaving millions without power — some for two weeks.

“It’s deja vu all over again,” Pistey said.

In Londonderry, N.H., Irene Stanley, 68, was sitting in a rocking chair next to a wood stove to keep warm, her royal blue beta fish in its container nearby. Stanley, who managed without power for nearly two weeks during the ice storm two years ago, said her mission for the day was to buy batteries to keep her radio operating.

In York, Maine, 70-year-old lobsterman Pat White, was able to use his generator to help cook a pancake breakfast Saturday to feed his neighbors who were without power — a father, his daughter and her baby. White and his wife, Enid, were planning what to serve them for dinner.

“We’ve got to use up some of the stuff in the refrigerator,” he said.

Nick Vermette, 49, a safety specialist for Central Maine Power, the state’s largest utility, was supervising crews restoring power in Portland on Saturday. He said the 17-hour days are exhausting.

“By the time you drive home take a shower, try to get to sleep, get up and come back, you’re averaging four to five hours sleep,” he said.By the time you drive home take a shower, try to get to sleep, get up and come back, you’re averaging four to five hours sleep,” he said.

TOKYO – The tsunami from Chile’s deadly earthquake hit Japan’s main islands and the shores of Russia on Sunday, but the smaller-than-expected waves prompted the lifting of a Pacific-wide alert. Hawaii and other Pacific islands were also spared.

In Japan, where hundreds of thousands of people were evacuated from shorelines, the biggest wave following the magnitude-8.8 quake off Chile hit the northern island of Hokkaido. There were no immediate reports of damage from the four-foot (1.2-meter) wave, though some piers were briefly flooded.

As it crossed the Pacific, the tsunami dealt populated areas — including the U.S. state of Hawaii — only a glancing blow.

The Pacific Tsunami Warning Center in Hawaii issued a warning for 53 nations and territories, but lifted it Sunday, though some countries were keeping their own watches in place as a precaution.

The tsunami raised fears the Pacific could fall victim to the type of devastating waves that killed 230,000 people in the Indian Ocean in 2004 the morning after Christmas. During that disaster, there was little-to-no warning and much confusion about the impending waves.

Officials said the opposite occurred after the Chile quake: They overstated their predictions of the size of the waves and the threat.

“We expected the waves to be bigger in Hawaii, maybe about 50 percent bigger than they actually were,” said Gerard Fryer, a geophysicist for the warning center. “We’ll be looking at that.”

Japan, fearing the tsunami could gain force as it moved closer, put all of its eastern coastline on tsunami alert and ordered hundreds of thousands of residents in low-lying areas to seek higher ground as waves generated by the Chilean earthquake raced across the Pacific at hundreds of miles (kilometers) per hour.

Japan is particularly sensitive to the tsunami threat.

In July 1993 a tsunami triggered by a major earthquake off Japan’s northern coast killed more than 200 people on the small island of Okushiri. A stronger quake near Chile in 1960 created a tsunami that killed about 140 people in Japan.

Towns along northern coasts issued evacuation orders to 400,000 residents, Japanese public broadcaster NHK said. NHK switched to emergency mode, broadcasting a map with the areas in most danger and repeatedly urging caution.

As the wave continued its expansion across the ocean, Japan’s Meteorological Agency said waves of up to 10 feet (three meters) could hit the northern prefectures of Aomori, Iwate and Miyagi, but the first waves were much smaller.

People packed their families into cars, but there were no reports of panic or traffic jams. Fishermen secured their boats, and police patrolled beaches, using sirens and loudspeakers to warn people to leave the area.

Elsewhere, the tsunami passed gently.

By the time the tsunami hit Hawaii — a full 16 hours after the quake — officials had already spent the morning blasting emergency sirens, blaring warnings from airplanes and ordering residents to higher ground.

The islands were back to paradise by the afternoon, but residents endured a severe disruption and scare earlier in the day: Picturesque beaches were desolate, million-dollar homes were evacuated, shops in Waikiki were shut down, and residents lined up at supermarkets to stock up on food and at gas stations.

Waves hit California, but barely registered amid stormy weather. A surfing contest outside San Diego went on as planned.

In Tonga, where up to 50,000 people fled inland hours ahead of the tsunami, the National Disaster Office had reports of a wave up to 6.5 feet (two meters) high hitting a small northern island, deputy director Mali’u Takai said. There were no initial indications of damage.

Nine people died in Tonga last September when the Samoa tsunami slammed the small northern island of Niuatoputapu, wiping out half of the main settlement.

In Samoa, where 183 people died in the tsunami five months ago, thousands remained Sunday morning in the hills above the coasts on the main island of Upolu, but police said there were no reports of waves or sea surges hitting the South Pacific nation.

At least 20,000 people abandoned their homes in southeastern Philippine villages and took shelter in government buildings or fled to nearby mountains overnight due to the tsunami scare. Provincial officials scrambled to alert villagers and prepare contingency plans, according to the National Disaster Coordinating Council.

Philippine navy and coast guard vessels, along with police, were ordered to stand by for possible evacuation but the alert was lifted late Sunday afternoon.

Indonesia’s Meteorology and Geophysics Agency said there was no tsunami risk for the archipelago as it was too far from the quake’s epicenter.

On New Zealand’s Chatham Islands earlier Sunday, officials reported a wave measured at 6.6 feet (two meters).

Oceanographer Ken Gledhill said it was typical tsunami behavior when the sea water dropped three feet (a meter) off North Island’s east coast at Gisborne and then surged back.

Several hundred people in the North Island coastal cities of Gisborne and Napier were evacuated from their homes and from camp grounds, while residents in low-lying areas on South Island’s Banks Peninsula were alerted to be ready to evacuate.

Australia’s Bureau of Meteorology canceled its tsunami warning Sunday evening.

“The main tsunami waves have now passed all Australian locations,” the bureau said.

No damage was reported in Australia from small waves that were recorded earlier in the day in New South Wales, Queensland, Tasmania and Norfolk Island, about 1,000 miles (1,600 kilometers) northeast of Sydney.

New Zealand’s Ministry of Civil Defense and Emergency Management downgraded its tsunami warning to an advisory status, which it planned to keep in place overnight.

JERUSALEM – Two parts of an ancient biblical manuscript separated across centuries and continents were reunited for the first time in a joint display Friday, thanks to an accidental discovery that is helping illuminate a dark period in the history of the Hebrew Bible.

The 1,300-year-old fragments, which are among only a handful of Hebrew biblical manuscripts known to have survived the era in which they were written, existed separately and with their relationship unknown, until a news photograph of one’s public unveiling in 2007 caught the attention of the scholars who would eventually link them.

Together, they make up the text of the Song of the Sea, sung by jubilant Israelites after fleeing slavery in Egypt and witnessing the destruction of the pharaoh’s armies in the Red Sea.

“The enemy said: ‘I will pursue, I will overtake, I will divide the spoil. My lust shall be satisfied upon them, I will draw my sword, my hand shall destroy them,’” reads the song, which appears in the Book of Exodus. “Thou didst blow thy wind, the sea covered them. They sank like lead in the mighty waters.”

An exhibit at Israel’s national museum dedicated to the Song of the Sea is now bringing together the two long-separated pieces.

One page of the song, known as the Ashkar manuscript, was previously housed in a rare books library at Duke University in North Carolina and was first displayed at the Israel Museum in Jerusalem in 2007.

That’s when a photograph of the manuscript in a local newspaper caught the eye of two Israeli paleographers, Mordechay Mishor and Edna Engel, who noticed it resembled a different page of Hebrew writing known as the London manuscript, presently part of the private collection of Stephan Loewentheil of New York.

“The uniformity of the letters, the structure of the text, and the techniques used by the scribe … it made it very clear to me,” Engel said.

The relationship would not be so clear to a casual observer. The Ashkar manuscript has been so blackened by exposure to the elements that the text is all but invisible, while the London manuscript is legible and far better preserved. But after close study of ultraviolet images, the experts were able to confirm that the texts were not only written by the same scribe, but were also part of the same scroll.

Scholars believe the scroll was written around the seventh century somewhere in the Middle East, possibly in Egypt. It is not known how the two parts were separated or what happened to the rest of the manuscript.

The museum arranged to have the London manuscript brought to Jerusalem. The new exhibit chronicles how the Song of the Sea was written through various ancient manuscripts, from the 2,000-year-old Dead Sea Scrolls to the manuscript known as the Aleppo Codex, written nearly a millennium later.

The reunification of the two pieces adds an important link in the chain, showing how the writing of the Hebrew Bible evolved through the so-called “silent” period — between the third and 10th centuries — from which nearly no Biblical texts survived. While in the Dead Sea Scrolls the song is arranged like prose, for example, in the newly reunited manuscript it is written like a poem, the same way it appears in the Hebrew Bible today.

The manuscripts are “filling the gap,” said Israel Museum curator Adolfo Roitman. “We can see we are dealing with a tradition that is still alive.”

The museum exhibit displays the manuscripts along with other depictions of the Song of the Sea from the museum’s permanent collection, including artistic renderings of the biblical passages in frescoes and Renaissance paintings and recordings of the song as it is chanted by Jews in different communities worldwide.

LOS ANGELES – Marie Osmond’s 18-year-old son Michael Blosil has died, the entertainer said Saturday.

Osmond said in a statement through her publicist that her family is devastated by the “tragic loss.” She did not provide details on the death.

Entertainment Tonight reported on its Web site that Blosil jumped to his death Friday night from a downtown Los Angeles apartment building.

Officers responded to an apparent suicide jump in the area, but the victim was not identified Saturday, Los Angeles Police Officer Gregory Baek said.

“My family and I are devastated and in deep shock by the tragic loss of our dear Michael and ask that everyone respect our privacy during this difficult time,” Osmond said in the statement.

Blosil reportedly left a note which referred to a lifelong battle with depression.

In 2007, Osmond said Michael was treated at a rehabilitation facility, but she didn’t disclose the nature of his problem.

Donny Osmond, Blosil’s uncle, told Entertainment Tonight: “Please pray for my sister and her family.”

Michael is one of Osmond’s five adopted children. She also has three other children from two marriages. She divorced Brian Blosil in 2007 after two decades of marriage. She and her first husband Stephen Craig divorced in 1985.

Osmond earned fame at age 13 with the hit song “Paper Roses,” and starred with her brother, Donny, on television’s “Donny and Marie Show” during the 1970s.

They perform a musical variety show regularly at the Flamingo Las Vegas Hotel and Casino. The hotel said Saturday’s performance was canceled

healthday Reporter – Fri Feb 26, 11:50 pm ET

FRIDAY, Feb. 26 (HealthDay News) — It’s not a particular brain region that makes someone smart or not smart.

Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume.

Instead, new research shows, it’s the connections between very specific areas of the brain that determine intelligence and often, by extension, how well someone does in life.

“General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons,” said Jan Glascher, lead author of a paper appearing in this week’s issue of the Proceedings of the National Academy of Sciences. “General intelligence relies on the connection between the frontal and the parietal [situated behind the frontal] parts of the brain.”

The results weren’t entirely unexpected, said Keith Young, vice chairman of research in psychiatry and behavioral science at Texas A&M Health Science Center College of Medicine in Temple, but “it is confirmation of the idea that good communication between various parts of brain are very important for this generalized intelligence.”

General intelligence is an abstract notion developed in 1904 that has always been somewhat controversial.

“People noticed a long time ago that, in general, people who are good test-takers did well in a lot of different subjects,” explained Young. “If you’re good in mathematics, you’re also usually good in English. Researchers came up with this idea that this represented a kind of overall intelligence.”

“General intelligence is this notion that smart people tend to be smart across all different kinds of domains,” added Glascher, who is a postdoctoral fellow in the department of humanities and social sciences at the California Institute of Technology in Pasadena.

Hoping to learn more, the authors located 241 patients who had some sort of brain lesion. They then diagrammed the location of their lesions and had them take IQ tests.

“We took patients who had damaged parts of their brain, tested them on intelligence to see where they were good and where they were bad, then we correlated those scores across all the patients with the location of the brain lesions,” Glascher explained. “That way, you can highlight the areas that are associated with reduced performance on these tests which, by the reverse inference, means these areas are really important for general intelligence.”

“These studies infer results based on the absence of brain tissue,” added Paul Sanberg, distinguished professor of neurosurgery and director of the University of South Florida Center for Aging and Brain Repair in Tampa. “It allows them to systemize and pinpoint areas important to intelligence.”

Young said the findings echo what’s come before. “The map they came up with was what we expected and involves areas of the cortex we thought would be involved — the parietal and frontal cortex. They’re important for language and mathematics,” he said.

In an earlier study, the same team of investigators found that this brain network was also important for working memory, “the ability to hold a certain number of items [in your mind],” Glascher said. “In the past, people have associated general intelligence very strongly with enhanced working memory capacity so there’s a close theoretical connection with that.”
