For whatever reason—and there’s endless scope to speculate – pain is a hot topic these days. “That’s gotta hurt!” we say of the extreme snowboarder who lands face-first while jumping a Volkswagon, or of our friend’s kid who flashes her tongue stud or lumbar tattoo. But we’re fascinated. In an age where pain is optional, it has acquired a strange new cachet.
On today’s maternity wards, experiments in mystical stoicism have replaced old-style epidural-aided childbirth (which at least offered mothers-to-be some relief) with “natural childbirth, where lucky women get to sweat and holler and squeeze the doula’s hand, the pain simply the price of being fully present in the moment. The Dene and the Inuit of the Northwest Territories would understand. Many of their traditional games – the mouth pull, the knuckle hop – involve the mutual affliction of pain. “If we know how much pain we can take,” an elder named Big Bob Aikens explained to writer John Vaillant not long ago, “we know we can survive if we are injured.” Most of us below the tundra line are so far away from needing pain for that reason that it’s hard to fully appreciate what Big Bob is getting at. But the possibility glimmers on the periphery of awareness that maybe the Inuit are onto something. Maybe anesthetizing pain is a bad idea, evolutionarily. Maybe learning to feel pain, to take it, to “live inside” it, to study it, to re-engineer our relationship with it, is part of the secret of advancing the species.

The first shot across the bow came in 2002, when Oxford paleontologist Martin Brasier challenged the authenticity of what were then widely regarded as the fossil remains of some of Earth’s first life-forms. In the bargain he took on one of paleobiology’s great lions, J. W. “Bill” Schopf of UCLA, who made that find and still defends it. “It was like tackling Jesus or Moses,” Brasier says.
Now Brasier has emptied his second barrel. In August he and David Wacey of the University of Western Australia staked their own claim to a candidate for the oldest known fossil: a set of Slinky-shaped cells found on an ancient beach in western Australia, just 20 miles from the site of Schopf’s discovery. Brasier asserts that his fossilized cells are the remains of primitive anaerobic bacteria that lived 3.4 billion years ago. Schopf’s samples, he believes, are just ancient, patterned rock, with no fossils at all.
Settling the debate matters a great deal. At its heart is one of the biggest questions in science: When and where did life begin? Brasier’s find suggests that life on Earth started not near some oceanic thermal vent but rather in a warm, oxygen-depleted bath near the surface. It also bolsters the case that there once was life on Mars.

he moment they were born, on October 25, 2006, in Vancouver, this much was known about Krista and Tatiana Hogan. The girls were conjoined—what used to be called “Siamese”—twins. Their skulls were fused such that their tiny bodies together made the shape of an open hinge, the girls facing the same direction but essentially away from each other. Each had her own organs and limbs, but they shared plenty of blood vessels in the netlike sheath beneath their scalp. And they shared something else, too, something believed to be unprecedented among living twins: a “bridge” of tissue connected their otherwise-separate brains amidships, at a crucial relay station called the thalamus.
Eight hours after the twins’ birth, a remarkable thing happened, and it immediately transformed the story of two little girls from Vernon, B.C., into something almost mythic. Tatiana got a shot and Krista flinched. Clearly, the girls were not just attached but connected. Sensory information passed between them.

Paula Wishart, a career counselor from Ann Arbor, Michigan, learned in her 40s a sinister family secret: Lynch syndrome runs through their genes.
Lynch syndrome is caused by a collection of genetic mutations that vastly predispose a person to an early and aggressive form of colon cancer. (In women it’s linked, too, with uterine or endometrial cancer.) The mutations were discovered in the early 1990s. That was too late for a whole string of Wishart’s ancestors—including her great-grandfather and her grandfather. Their mysterious deaths fostered the mythology that there was, as Wishart puts it, “bad blood in the family.”
Lynch syndrome is like an assassin hiding in the attic with a dozen different ways to kill you. It’s a specter so dire that, when Wishart’s aunt learned a decade ago that there were now tests for diseases like Lynch, “she wanted no part of it,” Wishart recalls. “The feeling was, ‘Why would I want to know that?’” That aunt died of colon cancer. Shortly thereafter, her daughter—Wishart’s beloved first cousin—succumbed to cancer in her 40s. “If my aunt had been screened, then my cousin would have been screened earlier,” Wishart says. “It could have prevented their deaths.”

hen asked to imagine the Earth in 2040, many scientists describe a grim scenario, a landscape so bare and dry, it’s almost uninhabitable. But that’s not what Willem van Cotthem sees. “It will be a green world,” says van Cotthem, a Belgian scientist turned social entrepreneur. “Tropical fruit can grow wherever it’s warm.” You still need water, but not much. A brief splash of rain every once in a while is enough. And voilà—from sandy soil, lush gardens grow.
The secret is hydrogels, powerfully absorbent polymers that can suck up hundreds of times their weight in water.
Hydrogels have many applications today, from food processing to mopping up oil spills, but they are most familiar as the magic ingredient in disposable diapers. The difference with agricultural hydrogels is that they don’t just trap moisture; they let it go again, very slowly, almost like time-release medication, into the root system of plants. That continuity of moisture is what brittle landscapes like deserts need to become fertile again. Water activates a mineralization process, setting free nutrients in the soil so that life can grow.

Let me tell you a few things about my relationship with the points of the compass, and then we’ll jump to the meat of this thing.
At shopping malls, my eldest daughter has to frequently tell me where we parked. She is five.
Once, while visiting Paris, I went out for a jog and got disoriented. Eventually I spotted a police officer, and I pulled from my shoe the address where we were staying. “Ah,” he said. “You want to go back to Paris.”
On a quest many years ago to climb the highest mountain on Vancouver Island, a pal and I got so lost that there was no turning back, because it just wasn’t clear which way back was. It wasn’t clear where forward was, either, except that we’d seen a plane fly in over the ridge ahead, so we went that way. (Did I mention that my pal was bleeding from a head wound?) It was a long shot but—don’t you see?—it was the only shot, because that slot in the horizon was our lone landmark.

Cave Junction, Oregon, was once, long ago, the center of a gold rush boom that, like so many booms, ultimately consumed its host. Prospectors mined the land around the towns in an ever-tightening circle, until the only gold left was below the saloons, assayers and burlesque halls. Those fell next. The towns were mined right out from under themselves—with no trace left of the old frontier burgs but scars in the earth.
The people who trickled back, decades later, came to satisfy a different urge: not to pursue something but to escape it. Certain hardy members of the hippie diaspora of the ’60s realized that you could live out here entirely under the radar and off the grid. With no one to badger you, you could pursue your own idiosyncratic dreams. You could, in fact, quietly build your better mousetrap and wait until the right time to spring it on the world—the very moment when the world needed saving.

It’s been called the biggest scientific project ever. And Vancouver scientists are poised to help understand the origins of the universe
from VANCOUVER MAGAZINE
Given Canada’s key role in the experiment, it would have been a little embarrassing if this business at the Large Hadron Collider near Geneva had destroyed the universe. In theory, it still could produce microscopic black holes that will suck us into oblivion and pull our screams in behind us. But frankly, scientists at TRIUMF-Canada’s national laboratory for particle and nuclear physics-aren’t too concerned. “These collisions are going on all the time with cosmic rays,” says Nigel Lockyer, TRIUMF’s director. “I wish we could make collisions of higher energy than what nature does routinely.”
No, any nail-biting at TRIUMF concerned whether the hardware would work on game day. TRIUMF built a part of the accelerator-a system of “kicker magnets” that spank the already fast-moving protons into the main ring of the collider where they really start to motor. There was a tense moment when word came from CERN (Compact Muon Solenoid Experiment) that some magnets had failed, followed by relief when they weren’t crucial and, as one TRIUMFer puts it, “they weren’t ours.” In fact, the “Canadian Insertion” worked perfectly and the Great Discovery Machine was up and humming, conducting the groundbreaking ATLAS Experiment, stalking the so-called God particle and probing the mysteries of the origins of everything.

Mirror neurons may hold the key to understanding how human beings respond to one another’s plight

Simon Lovell is a British-born stage magician whose long-running Broadway show Strange and Unusual Hobbies exploits his dexterity with playing cards. But for most of his adult life, Lovell turned a less reputable dime. He was a full-time con man. It was a trade he came by naturally. By age four he was already learning gambling-table tricks from his grandfather, and before long young Simon was traveling with carnivals and three-card-monte troupes, absorbing the patter and the confidence and the ethic of the “short con” (in and out before the victim knows what hit him). It was an easy way for Simon to put himself through college; it was an easy way to put himself through life. Like some opportunistic grifter in a David Mamet play, seducing hapless victims and then betraying them without remorse, Lovell plied his craft for ten lucrative years, until the age of thirty-one.
And then one day everything changed.

and other rallying cries from the fringes of the final frontier
from POPULAR SCIENCE
UC Berkeley space scientist Greg Delory devoured Carl Sagan’s books as a kid; now he hunts for extraterrestrial water—and life—in the solar system. Jeff Greason learned to pick locks at Caltech, from none other than Richard Feynman; now he burns LOX (liquid oxygen) in engines built by his California rocket company.Alexander Poleschuk spent six life-changing months aboard the space station Mir; now this Russian ex-cosmonaut obsesses over his nation’s lofty space goals—and its inability to pay for them.
Three men, three visions of space exploration. As NASA scrambles to recover from the Columbia tragedy, the next phase of spacefaring has already begun. It’s an era marked by new philosophies and agendas—and, according to Rick Tumlinson of the Space Frontier Foundation, a space-travel advocacy group, by three types of space adventurer. There are the Saganites, who yearn to comprehend outer space; the O’Neillians, who want to colonize it; and the von Braunians—who just want to get there first. Welcome to their worlds.
