The staggering statistics, detailed in the new Cancer Atlas and updated Tobacco Atlas, were released at the International Union Against Cancer conference in Washington, D.C., on Monday.

Health officials said that reducing tobacco use, improving nutrition and decreasing infection by cancer-causing viruses could cut global cancer rates sharply.

"We know with cancer, if we take action now, we can save two million lives a year by 2020 and 6.5 million by 2040," said Dr. Judith Mackay, a World Health Organization senior policy adviser.

The numbers in Canada are similarly sobering with tobacco use accounting for almost 30 per cent of all fatal cancers. Health Canada projects 153,100 new cases of cancer and 70,400 cancer deaths for 2006.

According to Statistics Canada, 22 per cent of Canadians aged 12 or older were smokers in 2005, down from 23 per cent in 2003. The cancer and tobacco atlases were published by the American Cancer Society with assistance from the World Health Organization and the Centers for Disease Control and Prevention.

The storm was nothing special. Its waves rocked the Norwegian Dawn just enough so that bartenders on the cruise ship turned to the usual palliative - free drinks.

Then, off the coast of Georgia, early on Saturday, April 16, 2005, a giant, seven-story wave appeared out of nowhere. It crashed into the bow, sent deck chairs flying, smashed windows, raced as high as the 10th deck, flooded 62 cabins, injured 4 passengers and sowed widespread fear and panic.

"The ship was like a cork in a bathtub," recalled Celestine Mcelhatton, a passenger who, along with 2,000 others, eventually made it back to Pier 88 on the Hudson River in Manhattan. Some vowed never to sail again.

Enormous waves that sweep the ocean are traditionally called rogue waves, implying that they have a kind of freakish rarity. Over the decades, skeptical oceanographers have doubted their existence and tended to lump them together with sightings of mermaids and sea monsters.

But scientists are now finding that these giants of the sea are far more common and destructive than once imagined, prompting a rush of new studies and research projects. The goals are to better tally them, understand why they form, explore the possibility of forecasts, and learn how to better protect ships, oil platforms and people.

The stakes are high. In the past two decades, freak waves are suspected of sinking dozens of big ships and taking hundreds of lives. The upshot is that the scientists feel a sense of urgency about the work and growing awe at their subjects.

"I never met, and hope I never will meet, such a monster," said Wolfgang Rosenthal, a German scientist who helped the European Space Agency pioneer the study of rogue waves by radar satellite. "They are more frequent than we expected."

Drawing on recent tallies and making tentative extrapolations, Dr. Rosenthal estimated that at any given moment 10 of the giants are churning through the world's oceans.

In size and reach these waves are quite different from earthquake-induced tsunamis, which form low, almost invisible mounds at sea before gaining height while crashing ashore. Rogue waves seldom, if ever, prowl close to land.

"We know these big waves cannot get into shallow water," said David W. Wang of the Naval Research Laboratory, the science arm of the Navy and Marine Corps. "That's a physical limitation."

By one definition, the titans of the sea rise to heights of at least 25 meters, or 82 feet, about the size of an eight-story building. Scientists have calculated their theoretical maximum at 198 feet - higher than the Statue of Liberty or the Capitol rotunda in Washington. So far, however, they have documented nothing that big. Large rogues seem to average around 100 feet.

Most waves, big and small alike, form when the wind blows across open water. The wind's force, duration and sweep determine the size of the swells, with big storms building their height. Waves of about 6 feet are common, though ones up to 30 or even 50 feet are considered unexceptional (though terrifying to people in even fairly large boats). As waves gain energy from the wind, they become steeper and the crests can break into whitecaps.

The trough preceding a rogue wave can be quite deep, what nautical lore calls a "hole in the sea." For anyone on a ship, it is a roller coaster plunge that can be disastrous.

Over the centuries, many accounts have told of monster waves that battered and sank ships. In 1933 in the North Pacific, the Navy oiler Ramapo encountered a huge wave. The crew, calm enough to triangulate from the ship's superstructure, estimated its height at 112 feet.

In 1966, the Italian cruise ship Michelangelo was steaming toward New York when a giant wave tore a hole in its superstructure, smashed heavy glass 80 feet above the waterline, and killed a crewman and two passengers. In 1978, the München, a German barge carrier, sank in the Atlantic. Surviving bits of twisted wreckage suggested that it surrendered to a wave of great force.

Despite such accounts, many oceanographers were skeptical. The human imagination tended to embellish, they said.

Moreover, bobbing ships were terrible reference points for trying to determine the size of onrushing objects with any kind of accuracy. Their mathematical models predicted that giant waves were statistical improbabilities that should arise once every 10,000 years or so.

That began to change on New Year's Day in 1995, when a rock-steady oil platform in the North Sea produced what was considered the first hard evidence of a rogue wave. The platform bore a laser designed to measure wave height.

During a furious storm, it registered an 84-foot giant.

Then, in February 2000, a British oceanographic research vessel fighting its way through a gale west of Scotland measured titans of up to 95 feet, "the largest waves ever recorded by scientific instruments," seven researchers wrote in the journal Geophysical Research Letters.

Once-skeptical scientists were soon holding conferences to discuss the findings and to design research strategies. A large meeting in Brest, France, in November 2000 attracted researchers from around the world.

It quickly became apparent that the big waves formed with some regularity in regions swept by powerful currents: the Agulhas off South Africa, the Kuroshio off Japan, and the Gulf Stream off the eastern United States, where the Norwegian Dawn got into trouble off Georgia. The Gulf Stream also flows through the Bermuda Triangle, famous for allegedly devouring large numbers of ships.

Dr. Bengt Fornberg, a mathematician at the University of Colorado who studies the giants, said the strong ocean currents appeared to focus waves "like a magnifying glass concentrates sunlight."

"It's the same idea," he said. "There are a few places in the world where there is a regular current, like a steady magnifying glass. In other places, the eddies come and go, and that makes the waves less predictable."

One way that rogue waves apparently form is when the strong currents meet winds and waves moving in the opposite direction, he said. The currents focus and concentrate sets of waves, shortening the distance between them and sending individual peaks higher. "That," Dr. Fornberg said in an interview, "makes for hot spots in a fairly predictable area."

A particularly threatening spot, he said, turned out to be where big oil tankers coming from the Middle East ride the Agulhas current around South Africa. There, the westward-flowing current meets prevailing easterly winds, at times disastrously.

"Three or four tankers a year there get badly damaged," Dr. Fornberg said. "That's one of the few places in the world where the phenomena is regular."

"With a big storm, you get lots of big waves," he added. "You have regular waves and then one or two giants. Then it's back to regular again."

The scientists who met at Brest in 2000, eager to track the phenomenon globally, laid plans to use radar satellites to conduct a census, calling it MaxWave.

They worked with the European Space Agency, which had lofted radar satellites in 1991 and 1995, as well as the German Aerospace Center and several other European research bodies. The radar beams were seen as potentially ideal for measuring the height of individual waves, based on the time it took the beams to bounce from orbit to the sea and back to space.

The MaxWave team, led by Dr. Rosenthal, examined three weeks of radar data and to its amazement discovered 10 giants, each at least 82 feet high. "We were quite successful," he said.

The team even tracked monster waves in a region of the South Atlantic where two cruise ships, the Bremen and the Caledonian Star, had come under assault.

Further confirmation with a different set of instruments came in September 2004 when Hurricane Ivan swept through the Gulf of Mexico.

It passed directly over six wave-tide gauges that the Naval Research Laboratory had deployed about 50 miles east of the Mississippi Delta. Dr. Wang and his colleagues analyzed the data and found to their surprise waves measuring more than 90 feet from trough to crest.

"We had no idea," Dr. Wang recalled. "It was the right time and the right place."

Already, the scientists said, naval architects and shipbuilders are discussing precautions. Some of the easiest are seen as increasing the strength of windows and hatch covers. But even the best physical protections may fail under assault by tons of roiling water, so the best precaution of all will be learning how to avoid the monsters in the first place.

Increasingly, scientists are focusing on better understanding how the big waves form and whether that knowledge can lead to accurate forecasts - a feat that, if achieved, may save hundreds of lives and many billions of dollars in lost commerce.

A suspected culprit, in addition to wind-current interactions, is the amplification that occurs when disparate trains of waves (perhaps emanating from different storms) come together. Such intersections are seen as sometimes canceling out waves, and other times making them higher and steeper.

Another birth ground is seen as choppy seas where several waves moving independently merge by chance. But scientists say a giant of that sort would live for no more than a few seconds or minutes, whereas some are suspected of lasting for hours and traveling long distances.

As for forecasts, oceanographers are focusing on the interplay of exceptionally strong winds and currents, especially in the Agulhas off South Africa.

Dr. Fornberg said that several years ago South African authorities began issuing predictions. "That's the only place the theory has succeeded," he said.

Dr. Rosenthal said that in the future the continued proliferation of radar satellites should create an opportunity to better understand not only the habitats of the giants but in theory also individual threats, bringing about a safer relationship between people and the sea.

"There will be warnings, maybe in 10 years," he said. "It should be possible."

The girls were among 49 guests at the resort. All the guests were accounted for during the investigation of the incident.

Two people died in the explosion and fire that remain under investigation by the Wisconsin State Fire Marshal, Door County Sheriff's Department and Sister Bay/Liberty Grove Fire Department. The fire department was dispatched to the scene at 2:35 a.m. Monday.

The focus of the investigation was the condominiums at Cedar Grove and the adjacent Pioneer Store, a landmark Ellison Bay building flattened by the explosion.

The identities of the dead were not released pending notification of relatives.

Both bodies were recovered by mid-morning Monday and taken to the Brown County Medical Examiner's office in Green Bay for autopsies.

The girls and other people displaced by the explosion and fire were given food and shelter at the Ellison Bay fire station, one of two operated by the Sister Bay/Liberty Grove Fire Department.

Its source was the large sunspot at active region 898. These storms carry billions of tons of matter at millions of miles per hour. These coronal mass ejections clouds of energized particles may reach the Earth in two to three days, creating the possibility of some brilliant aurora displays further down from the North and South Polar regions than usual.

Sometimes they can also create communication, navigation and satellite problems. However, in this case, due to its sharp angle off to the right, it is quite unlikely that we will experience any strong effects from this storm.

In coronagraph images, an occulting disk blocks out the sun and some of the area beyond it creating something like an artificial solar eclipse. The size of the sun is represented by the white circle.

University of Stavanger Professor Per Amund Amundsen, a member of the Stavanger Astronomy Society, told Aftenposten meteorites land in Norway as often as every month, but most are never found. He called the incident 'extremely exciting.'

The meteorite might a valuable sales object, Aftenposten said, noting prices on the Internet for other meteorites ranged to more than $100,000.

Dr. Jeffrey Ellenbogen of Harvard Medical School in Boston and his colleagues studied 48 healthy adults aged 18 to 39 who had no sleep problems.

The experiment was designed to test whether sleep helps build and maintain memory and overcome interference, the tendency to forget something else when learning a new piece of information.

In the lab, participants tried to memorize 20 pairs of words and were later tested on their recall.

Participants were divided into four groups:

* Sleep before testing.
* Wake before testing.
* Sleep before testing with interference.
* Wake before testing with interference.

Brain active during sleep

In this case, the interference or distraction was a second list of word pairs that participants were supposed to try to ignore during testing.

Those who slept between learning and testing were able to recall more of the original words compared with those who didn't get to sleep.

The beneficial effect was even starker between the sleep-interference group, with an average recall of 76 per cent, and the the wake-interference group at 32 per cent, the team reports in Tuesday's online issue of the journal Current Biology. "This is the first study to demonstrate that sleep protects declarative memories from associative interference in the subsequent day," the researchers wrote, adding that sleep "plays an active role in declarative-memory consolidation."

The results add to the evidence supporting the role sleep plays in declarative memory, based on studies on animals and brain imaging, the researchers said.
