As a person who cares deeply about the preservation of natural spaces and ecosystems, I have mixed feelings about the very existence of Lake Powell, America’s second-largest man-made lake. One general rule about dams is that they present an ecological nightmare for most living things downstream – unless those living things require electricity for powering flat screen TVs and massive air conditioning units. Electricity is after all the the main purpose of creating dams and the huge lakes behind them.

The lake gets its name from Major John Wesley Powell, a Civil War veteran who, in 1869, explored the Green and Colorado rivers, along with eight other people. Almost a century later, the Glen Canyon dam was completed, and Lake Powell began filling up in 1963. It took seventeen years to inundate the giant bathtub of bright red rock, and today it’s over 500 feet deep in some spots. The water levels fluctuate pretty dramatically depending on spring snowmelt, and electricity requirements determine how much water must be let out to spin the dam’s eight massive generators.

Lake Powell straddles the Utah/Arizona state line and is 186 miles in length, with almost 2,000 miles of shoreline. How is this possible? There are hundreds of “fingers” or canyons extending from the lake's main channel. This is great because you have the chance to find a secluded little canyon all for yourself and your buddies. What’s not great is that some of these fingers contain prehistoric human artifacts and dwellings that are now underwater, most likely never to be seen again.

In the early 1980s, just after the lake had reached full capacity, a wild band of eco-anarchists closely associated with the writer Edward Abbey took it upon themselves to rise up in protest of the Glen Canyon dam. Several of these people went on to form Earth First!, a non-violent group devoted to fighting for various environmental causes. A few of those folks splintered off to form arguably more-violent groups, such as the Earth Liberation Front (ELF). You can read more about this topic in my interview with Ken Sanders, a close friend of Abbey’s, and one the founders of Earth First!

Concern for ecological well-being aside, I like to speed across a glassy surface under the power of a two hundred horsepower outboard engine as the sun creeps over the horizon in the morning, with a beer in my hand, searching for a place to catch huge largemouth bass. That’s what I found myself doing for six days in a row in the spring of 2009.

A buddy of mine makes an annual trip to the lake, where he and a dozen other guys rent a houseboat for sleeping and drinking, and they usually have four to six of the aforementioned high-powered bass boats for fishing.

These guys are serious. And even when the fishing is not so good, they know how to catch fish. For example, when we arrived at Lake Powell conditions were not good for fishing because the lake was “turning over,” which is a phenomenon that occurs on most lakes in the spring. During the winter months, the deeper parts of the lake are warmest, but when the lake turns over, the colder water ends up at the bottom, while the warm water comes to the top, bringing with it a lot of algae. This inversion makes fishing poor for two reasons. First, the algae makes water visibility bad, and second, the change in water temperature throws fish off from their normal behavior patterns, since temperature often determines at what depth the fish like to be. Fortunately, lakes – no matter what size – usually turn over very quickly. So, while the fishing was slow at the beginning of our trip, by the last few days the water had cleared up, the temperatures had stabilized, and we were up to our gills in stripers and largemouths.

You won’t see many fishermen or tourists along the shores of Lake Powell. This is not only because you’d need a lot of line to drop your bait down 600 feet of cliff face into the water, but also because the surrounding “slickrock” terrain is not accessible by any roads. And although thousands of people visit the lake on any given weekend, it’s big enough that you won’t see many of them.

If you’ve parked your houseboat in one of the fingers of red rock, you might wake up to see a coyote, bobcat or mule deer trotting along the water’s edge, or, if you’re lucky, you’ll see a desert bighorn sheep defying gravity, making its way across the face of a vertical cliff. We didn’t see any sheep on our trip. But we caught a lot of fish, drank a lot of beer, and thought gosh dang-it, maybe this lake wasn’t such a bad idea after all.

iPad Survives Fall From Edge of Space in Jaw-Dropping Video


A new video has captured an Apple iPad's mindboggling fall to Earth from a balloon in the stratosphere in what may be the ultimate tablet survivor tale.
The high-definition video shows the iPad falling from a height of 100,000 feet (30,480 meters), with the blackness of space and the bright curve of Earth providing a stunning backdrop. The device free-falls all the way back to Earth to make a crash landing on a rocky Nevada hillside.
The video was recorded by the Rhode Island-based company G-Form, which designs protective electronics cases and athletic pads.
"We are usually known for making the most protective gear on the planet," said Thom Cafaro, G-Form's vice president of innovations, in a Jan. 6 statement. "So we decided why not raise the bar to off the planet too." [Photos and video of iPad's space fall]










G-Form officials used a weather balloon to carry the iPad up into the Earth's stratosphere, where the balloon burst and allowed its payload to begin the long fall back to the ground. G-Form wrapped the iPad in one of its 6-ounce protective "Extreme Edge" cases to test how well the covering performed in such a long drop.
"Perhaps even more remarkable than the dramatic hi-def footage itself is the fact that the iPad survives the adventure, remaining fully functional," G-Form officials said. The company will be showcasing its electronics cases this week at the 2012 Consumer Electronics Show in Las Vegas, Nevada.
Cafaro said that the device was "the first iPad that's ever free-fallen from space and survived to play more movies."

G-Form's stratospheric iPad is not the first Apple tablet to soar into space and its environs.
In October, Russia put two iPads in space as cargo aboard a Russian supply ship which launched to the International Space Station. They were reserved for use as entertainment devices for the space station's crew. The iPads joined a set of iPhone 4 phones, which were launched to the space station earlier in 2011 to be used in experiments.
Astronauts have also carried Apple's iPods with them on space shuttle and station-bound missions in order to listen to music while exercising, gazing out the window or other down time in orbit.
The iPad's stratospheric fall is the latest example of balloon-launched technology carrying custom-built tech to amazing heights. During NASA's final space shuttle missions in 2011, student groups used similar balloons to launch home-made camera platforms into the stratosphere to snap amazing photos of shuttle launches from above.
This story was updated to correctly identify the iPhone 4 devices currently aboard the International Space Station.

The shoes are still left outside the cabins to be polished: An eerie trip with the tourists diving two miles to see the Titanic


For 13 years people have been able to drop down to the depths of the Atlantic Ocean in submersibles to see the remains of the Titanic. But now, hundred years on after it sank, these expeditions are coming to close to allow the ship to rest in peace. Here, ROB McCALLUM who works for the deep-sea exploration company that took 150 people down there, describes the underwater journey

As the craft glides through the freezing depths of the ocean, more than two miles below the surface, I stare out through the thick glass window into the abyss.
From the external lights of our vessel, I can see across the ancient terrain, which looks almost like a lunar landscape. Occasionally strange aquatic creatures dart across my vision, adding to the alien atmosphere.
Then suddenly, there it is, the sight I shall never forget. Rising before my eyes is the prow of the most famous ship in the world.
Tales from beyond the grave: The Titanic lies still and rusting in its final resting place
Tales from beyond the grave: The Titanic lies still and rusting in its final resting place
I am peering at the wreckage of the RMS Titanic, which plunged to this watery, icy grave almost a century ago in April 1912.
Even in the darkness of the ocean floor, the front part of the mighty vessel still looks magnificent, the encrusted railings and sweep of her hull instantly recognisable.    
Our submersible continues its journey over the remains of the mighty ship, and I look bewitched at the famous grand staircase and the promenade deck where once the wealthy passengers briefly revelled in all their glorious opulence before the iceberg was struck.
Further along, about a mile from the prow, we find the rear part of the ship, more badly damaged than the prow, with great sheets of metal ripped from its sides.  
But even in her broken, decaying state, this ghostly relic exudes an epic sense of majesty. For what was so striking about the wreckage is its colossal size.
The two key sections of the ship make vast monuments on the ocean bed.

Even one of the main three-bladed propellers, built of solid bronze and remarkably well preserved, is more than twice as heavy as our 18-ton submersible — a submarine which allows detailed exploration of the sea bed.
The Titanic was the largest ship of its time, and one of the most beautiful ever created. But even now, all these years after the tragedy, the wreck of this leviathan still has the ability to inspire and humble.
My chance to view the wreckage arose because of my position with the Isle of Man-based company, Deep Ocean Expeditions, which specialises in deep-sea research and exploration, mainly for scientific, film-making and investigative purposes.
For our expeditions, we work with the PP Shirshov Institute of Oceanology, part of the Russian Academy of Science. They are the owners of the twin Mir submersibles, each capable of depths of 20,000ft. By working together, we are able to assist the Institute’s science work, as well as making a contribution to the Mirs’ operating costs.
One of our most popular trips is to see the remains of the German battleship the Bismark, which was sunk by the Royal Navy in 1941 about 350 miles off the south-western Irish coast.  
The other, more notorious trip is to the wreck of the Titanic, which was discovered in 1986 by the renowned American oceanographer Dr Robert Ballard, who, incidentally, also found the Bismark in 1989.

Over the past decade, nearly 200 Titanic dives by the company have taken 150 individuals down to see it, and — despite the $59,000 (£38,000) cost — the expeditions have never been more over-subscribed than for this year — the 100th anniversary of the disaster.    
The clients have included bankers, teachers, pilots, doctors, historical experts and sometimes the descendants of survivors or those who perished in the tragedy.   
But, after 13 years, 2012 is also the last time we will be running such trips to the Titanic.
It has been a wonderful adventure, but with the centenary approaching, now is the proper moment to draw these expeditions to a close and allow this tragic ship to rest in peace.
There are only five submersibles in the world — made of high-tech metals — that can withstand the immense pressure of the conditions around the wreck, about 12,500ft below the surface.  
Expeditions begin with passengers boarding a larger ship in Newfoundland, which carries them and the submersible out to the spot where the Titanic sank. 
The passengers are generally given a day to familiarise themselves with the craft and have a briefing about the forthcoming trip; they then attend lectures in Titanic history, oceanography and deep-sea operations.
Costly: To pay a visit down to the Titanic and witness sights like this white China still in the wooden sideboards of the reception rooms it will cost around £38,000

The dive begins the next morning, taking roughly two hours to reach the ocean bed.
At a depth of about 800ft, the submersible descends into darkness, for this is the maximum depth to which the sun’s rays can penetrate. As we travel further down, the enveloping blackness is broken only by the sub’s own lights.   
Once the vessel reaches the bottom, it manoeuvres its way around the two main sections of the ship for between four to eight hours, as well as looking at the other debris strewn across the sea bed.
The sights are truly remarkable — far more astonishing than any photograph can convey. Though the stern of the ship was badly damaged because it hit the ocean bed so hard — having travelled through the water at an estimated speed of 30 knots (the marine equivalent of 35mph) after the Titanic broke up — it is fascinating to see the vast engine rooms down there, full of massive machinery.
Equally arresting are the three immense propellers, between them weighing more than 100 tons and the two biggest of which were 23ft in diameter. Thanks to their sturdiness, they have survived well.
There is, however, no sign of the four enormous funnels, which would have been ripped off as the Titanic began her descent. Their fragments would have scattered over a wide area.

It is also possible to glimpse the interiors of some of the cabins, especially where the outer steel sheets of the hull were ripped away. Although the woodwork and fabrics have long gone, the metal walls and bronze and brass fittings remain.
Particularly poignant are the quarters of Captain Smith, who, in true heroic naval traditions, went down with his ship.
Of his three rooms, his bathroom is most clearly visible — his porcelain bathtub still in remarkably good condition.
Perhaps even more astonishing are all the artefacts strewn on the ground around the two main sections. Everywhere you look there are bottles, crockery, cutlery, even suitcases and shoes.
No clothes, carpets or other such material survives, as all that would have long rotted or been eaten by living organisms.
But anything leather has generally stayed in good condition and is only covered in a layer of silt.
Indeed, the number of shoes is surprising. This is because the ship went down just before midnight, at a time when many passengers would have retired to their cabins, undressed and put their shoes outside the door, ready to be cleaned by the staff.

Though sights like this are a poignant reminder of the human cost of the tragedy, there is nothing remotely macabre or ghoulish about visiting the wreckage.
There are no remains from any of the 1,514 victims who perished in the disaster. Their bodies would have been cast over a huge area, since many of them drowned or died of hypothermia in the freezing ocean. Other corpses, dragged down with the ship, would eventually have drifted away or been obliterated by the sea life that lurks in these depths.
In fact, the existence of other animal life so deep in the ocean is one of the most compelling features of a visit to the Titanic.  
As you travel down below 10,000ft, it almost seems impossible that any organism could survive in such a hostile environment. Yet even in the icy blackness, nature flourishes.    
On my trips to the wreckage, I have been astounded at the range of strange beings, such as six-inch rat-tailed fish, white-bodied crabs and creatures that give off light: blue, green and white flashes as they attract mates, or lure prey.
Even so, nothing can beat the awesome image of the Titanic itself.
The tragedy was a turning-point in history, the moment when man realised that nature could not always be tamed by technology, that no ship could ever be unsinkable.
Whenever I gaze in wonder at the wreckage, I sense that I am looking at an important part of mankind’s rich, sometimes distressing narrative; the same feeling I experience when visiting memorial cemeteries to the heroes who fell in the bloodstained fields of northern Europe during World War I.   
We come to these places to remember — and to learn from those who have passed before us.      
It will be an honour to see the Titanic, in all her ruined glory, one last time.

World's Smallest Memory Bit Stores Data Using Just 12 Atoms



The world’s smallest magnetic data storage unit is made of just 12 atoms, squeezing an entire byte into just 96 atoms, a significant shrinkage in the world of information storage. It’s not a quantum computer, but it’s a computer storage unit at the quantum scale. By contrast, modern hard disk drives use about a million atoms to store a single bit, and a half billion atoms per byte.
Until now, it was unclear how many (or how few) atoms would be needed to build a reliable, lasting memory bit, the basic piece of information that a computer understands. Researchers atIBM and the German Center for Free-Electron Laser Science decided to start from the ground up, building a magnetic memory bit atom-by-atom. They used a scanning tunneling microscope to create regular patterns of iron atoms aligned in rows of six each. They found two rows was enough to securely store one bit, and eight pairs of rows was enough to store a byte.
Data was written into and read out of the bits using the STM — so it’s not like this type of bit will be integrated into hard disks anytime soon. But it answers some fundamental questions about the nature of classical mechanical systems, said Andreas Heinrich, the lead investigator into atomic storage at IBM Research Almaden and an author on a new paper describing the teeny bit. The team was interested in the transition from quantum to classical behavior, he said.
“If you take a single atom, you have to look at quantum mechanics when you describe its behavior,” he said in an interview. “As you make the (system) bigger and bigger, several iron atoms start talking to each other, and at some point you can ignore all of this quantum behavior and just think of them as a classical magnetic structure.” It turns out that point is around 12 atoms big.
“Many people would anticipate you would have to use quantum mechanical systems to describe these structures,” Heinrich said. “That was the most surprising thing to me.”
At the smallest scales, quantum effects blur stored information. A bit using six atoms would switch magnetic states — switching from “0” to “1” — about 1,000 times per second, for instance, which is much too frequently to be useful for data storage, Heinrich said. Eight atoms switch states once per second. But 12 atoms switched their states infrequently enough to be usable for storage — instead, an outside magnetic influence (in this case, the STM) changes their states. The nano magnets are only stable at a chilly 5 degrees Kelvin, or -450 degrees F.
The other breakthrough in this paper is the bits’ antiferromagnetism — this marks the first time antiferromagnetism has been used to store data. Ferromagnets, used in most modern data storage and other applications, use magnetic interactions between iron atoms to align all the atoms in a single direction. This creates a magnetic field that can be read out. This becomes a problem at the teeniest scales, however, because tightly packed magnetic bits can interfere with each other — this limits the downsizing of data storage systems. But this new 12-atom bit uses antiferromagnetism — the atoms are aligned in opposite directions, meaning they spin in alternating directions. The iron atoms were separated by nitrogen atoms and induced with the STM to spin differently, Heinrich said. This allowed them to be packed closer together, greatly increasing storage density.
The researchers switched the bit's magnetic state five times to store the ASCII code for each letter of the word “think,” one of Big Blue’s slogans.
Sebastian Loth, who left IBM for CFEL four months ago and is lead author of the paper, said the 12-atom bit raises plenty of new questions for classical computing at quantum scales.
“We can now use this ability to investigate how quantum mechanics kicks in. What separates quantum magnets from classical magnets? How does a magnet behave at the frontier between both worlds? These are exciting questions that soon could be answered,” he said.
The paper appears in this week’s issue of Science.

GM, Segway team up on 200-mpg 2-seater

on Sunday, 15 January 2012

The Project PUMA prototype takes a spin in Brooklyn on Saturday.
General Motors (GM) is teaming with Segway, the scooter company, to develop a battery-powered vehicle to cut urban congestion and pollution.

The companies plan to announce the partnership Tuesday in New York, where they are testing a prototype of the partially enclosed, two-seat, two-wheel scooter. The venture is called Project PUMA, for Personal Urban Mobility and Accessibility.

The companies hope to recruit partners, such as cities or colleges, to set up Puma travel lanes, like bicycle lanes. They'd be used to test the vehicles and their on-board wireless communicators designed to keep them safely apart and even operate them while drivers do other tasks.

The Pumas also could be operated manually. Not intended for highway use, they would hit about 35 miles per hour and go up to 35 miles on a charge.


"There's no technology that has to be invented here. It's really just putting the pieces together," says Chris Borroni-Bird, director of the project for GM.

Nonetheless it could take years to get to market. "It's not going on sale anytime" soon, he said.

The partnership with Segway began about 18 months ago, predating GM's emergency survival loans from the government.

GM is developing the electronic wireless systems for safe, autonomous operation. Segway is responsible for the self-balancing, electric, two-wheel chassis. The prototype has "training wheels" front and rear, helpful at stoplights. Pumas would use lithium-ion batteries, like those Segway uses in its stand-up scooters.

Though being unveiled in New York, the Pumas might appeal most in densely packed cities in places such as India and China, Borroni-Bird says. There they would seem a big step up from bicycles. Americans, who are used to cars, might not take them as seriously.

He forecasts energy consumption equivalent to 200 miles per gallon of gasoline. That falls to about 70 mpg adding in fuel to generate electricity used to charge its battery.
