Sneakerheads’ souls crumble as their soles crumble

Sneakerheads’ souls crumble as their soles crumble

By on 18 May 2015commentsShare

Sneakerheads are in the midst of a crisis, as they watch their prized possessions — those sick kicks they’ve been coveting for years — literally fall apart in their hands.

Turns out, those old-school Nikes are so out-of-this-world, they actually can’t survive Earth’s atmosphere. Wired has the scoop, and it’s truly heartbreaking. Take the story of Nagomo Oji, a Japanese sneakerhead who decided to whip out his DS/OG Air Max 95s with midsole BWs (DS = dead stock; OG = original; DS/OG = $$; BW = big window) after 20 years:

As soon as he planted his feet, Oji sensed something was terribly wrong. The midsoles flattened, and his footing became strangely unstable. He didn’t realize it at the time, but the polyurethane (PU), that squishy, shock-absorbing material sandwiched between the upper and the outer sole, was more than ten years past its projected lifespan.

After just one step, the hardened PU foam fractured and collapsed, like arid soil crumbling beneath the boots of a Dust Bowl Okie. Oji looked down in disbelief. With the inner soles completely detached from the uppers, his feet were actually touching the ground. His beloved Air Maxes had just morphed into Fred Flintstone shoes.

Or this tearjerker about a “geriatric hoarder” in Buenos Aires who has a whole showroom full of DS/OGs:

All of these shoes were found in various states of decay in one of the biggest known cases of PU mass destruction. Seven minutes into the video, collector Robert Brooks pulls a forgotten artifact labeled Silver Wind from the stacks. He’s elated. It’s an obscure Adidas runner that’s eluded him for “a long, long time.” But as he lifts the shoe, the sole peels off and falls into the box. Recounting the story later, he sighs and whimpers “No!” stretching out the syllable for a few seconds, like a Loony Tunes character plunging from a high cliff into the abyss.

The polyurethane-injected foam soles common in a lot of sneakers tend to spontaneously fall apart after a while. Who knew? Certainly not the executive director of the Polyurethane Foam Association, who spoke with Wired about the problem and seemed shockingly out-of-the-loop: “I’ve never seen a technical paper on polyurethane shoes falling apart. But now that you mention it, I’ve owned several pairs of shoes that started cracking inside and outside. I didn’t know if they were just poorly made or if I stepped into something.”

Come on, man! Try reading this 2011 study on the aging performance of polyurethanes, which says that plastics like the one used in these sneakers are susceptible to hydrolysis and oxidation. Here’s a translation from Wired:

That’s right, the two things that make human life possible — water and air — are killing our shoes. Their role in degrading polyurethane can be attributed to the chemical processes of hydrolysis (in the presence of moisture) and oxidation (in the presence of oxygen). Simply put, the humidity in the air, and, yes, even the air itself, seeps into the PU and, slowly but surely, breaks it into itty-bitty sticky pieces. Delve deeper into the subject, and the news only gets worse. Bottom line: Pricy collectables shouldn’t be made out of PU.

But there’s good news! SonBinh T. Nguyen, a chemistry professor at Northwester University, (jokingly) told Wired that sneakerheads can preserve their treasures if they just keep them in an “airtight steel vessel filled with argon.”

Zing! But seriously, isn’t this disintegrating sneaker fiasco really just one big metaphor for the impending demise of our species? We built a society that’s cheap, fast, and flashy. Sustainable? Not so much. And now, climate change is the water and oxygen to our DS/OG Air Max 95s. But good news! If all else fails, we could all just go live in steel bunkers.

The windmill could get a snazzy green facelift, thanks to Dutch architects

Reinventing the wheel

The windmill could get a snazzy green facelift, thanks to Dutch architects

By on 24 Feb 2015commentsShare

The Netherlands just keeps one-upping the rest of the world. Recently, a Dutch construction firm installed a solar panel bike lane and then engineers went ahead and made another bike path glow-in-the-dark. Not that we’re keeping score or anything.

Now, the Dutch Windwheel Corporation has plans to build a 570-foot structure in Rotterdam that would be equal parts architectural marvel and green-tech wünderkind. Basically, the project would turn the nation’s iconic windmill into a high-tech real-estate development.

Here’s Smithsonian with the science:

The Wind Wheel’s design, made of two massive rings and an underwater foundation, plans to incorporate other green technologies, including solar panels, rainwater capture and biogas creation. The biogas will be created from the collected waste of residents of the 72 apartments and 160 hotel rooms that are planned for the inner ring.

The outer ring is set to house 40 cabins that move along a rail like a roller coaster, giving tourists a view of the city and the surrounding countryside, much like the London Eye or Las Vegas’ High Roller, which became the world’s tallest observation wheel when it opened in 2014. The cabins have glass “smart walls” that project information — the current weather, for example, and the heights and architects of buildings — onto the panorama. A restaurant and shops are also planned within the proposed structure.

Another plus: The wind wheel would also be a hub for new green technology businesses and an opportunity to create more jobs in the country.

Sounds sweet, right?

Well, here’s the catch: The technology needed to complete the project is still in the works. More from Smithsonian:

While aspects of the Wind Wheel’s design seem futuristic, the technology will have several years to advance before final construction gets underway. Duzan Boepel, the project’s principal architect, says that the Wind Wheel is still in its beginning phases. … He says if they prove that the wheel’s bladeless turbine tech can be scaled up for use in the Wind Wheel, the building may be finished by 2025.

Yeah, we will all be dreaming about this for the next decade. And yes, the Netherlands could win another batch of green points.

Climate change is flooding out American coastlines

Drowning in dangers

Climate change is flooding out American coastlines

U.S. Coast Guard

Flooding caused by Hurricane Arthur on the Outer Banks of North Carolina.

Hurricane Arthur is no more than a holiday-dampening memory in the minds of many East Coast residents and visitors. But the 4.5-foot storm surge it produced along parts of North Carolina’s shoreline on July 4 was a reminder that such tempests don’t need to tear houses apart to cause damage.

As seas rise, shoreline development continues, and shoreline ecosystems are destroyed, the hazards posed by storm surges from hurricanes are growing more severe along the Gulf Coast and East Coast.

Two soggy prognoses for storm-surge vulnerabilities were published on Thursday. A Reuters analysis of 25 million hourly tide-gauge readings highlighted soaring risks in recent decades as sea levels have risen. Meanwhile, a company that analyzes property values warned of the dizzying financial risks that such surges now pose.

First, here are highlights from the Reuters article:

During the past four decades, the number of days a year that tidal waters reached or exceeded National Oceanic and Atmospheric Administration flood thresholds more than tripled in many places, the analysis found. At flood threshold, water can begin to pool on streets. As it rises farther, it can close roads, damage property and overwhelm drainage systems. …

The trend roughly tracks the global rise in sea levels. The oceans have risen an average of 8 inches in the past century, according to the 2014 National Climate Assessment. Levels have increased as much as twice that in areas of the Atlantic and Gulf coasts where the ground is sinking because of subsidence – a process whereby natural geological forces or the extraction of underground water, oil or gas cause the ground to sink.

The most dramatic increases in annual flood-level days occurred at 10 gauges from New York City to the Georgia-South Carolina border, a stretch of coast where subsidence accounts for as much as half the rise in sea level in some locations, according to U.S. Geological Survey studies.

Also on Thursday, data and analytics firm CoreLogic published its annual storm surge report — a document that’s based on data produced for the insurance company. The firm’s latest analysis concluded that 6.5 million homes are at risk of being damaged by a category 1 hurricane’s storm surge. About 3.8 million of those homes are along the Atlantic Coast and the rest are along the Gulf Coast. Florida and Texas are most at risk. Rebuilding all of those homes would cost an estimated $1.5 trillion, the company’s analysts concluded.

NYC’s Unsolved Murder Victims Are Disproportionately Minorities

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Justice comes slower for homicide victims killed in New York’s poorer outer boroughs than it does for the denizens of rich, relatively homicide-free Manhattan.

That’s according to a New York Daily News investigation analyzing the number of homicide detectives the city assigns to assist local precincts during the critical first hours following a murder. The investigation also looked at how the city allocates the scarce resources of its cold case squad. Reporters found that there are 10 homicides detectives serving Manhattan South, an area where only 10 murders were reported in all of 2013—one homicide detective per case. By contrast, Brooklyn North, where 86 New Yorkers were murdered in 2013, has 17 homicide detectives—each handling an average of five cases.

The result is a staggering number of unsolved murders in Brooklyn, Queens, and Bronx precincts, the majority of which involve Latino or black victims. The News tallied 77 open murder investigations in Brooklyn, 39 in the Bronx, 26 in Queens, 15 in Manhattan, and two in Staten Island. The precincts with the most open murder cases are in Brookyln’s East Flatbush (10 out of 12 unsolved), Crown Heights, (nine out of 13 unsolved), and East New York (eight out of 17 unsolved) neighborhoods. The News found that 86 percent of last year’s homicides involving a white victim have been solved, compared with 45 percent of murders with a black victim and 56 percent of murders involving a Hispanic victim.

It’s not hard to figure out why such a disparity exists. “Manhattan is treated differently than the outer boroughs because that’s where the money is,” Joseph Giacalone, who retired last year as commanding officer of the Bronx Cold Case squad, told The News.

The scarcity of resources for murder investigations is partly explained by cuts and retirements that greatly reduced the number of detectives serving New York’s homicide and cold case squads. For example, there are roughly 1,500 unsolved homicides on the books in New York City. But the number of detectives working to make arrests in cold cases has plummeted, from 50 when the squad formed in 1996 to just eight today.

Still, the city’s clearance rate—the number of homicide arrests detectives make each year compared with the number of new homicides reported in the same time period—has averaged about 70 percent since the 1990s. Yet it’s the precincts in the poorer areas of outer boroughs have lagged behind badly. Manhattan homicides, Giacalone said, “get probably double the amount of cops that you see in Brooklyn…It’s just part of the deal.”

That is cold comfort to a person like Donna Rayside, whose son, Dustin Yeates, was killed in May in Brooklyn’s Flatland neighborhood. Police in that precinct, the 63rd, have not made an arrest in his case. “With eight killings in 2013, the 63rd precinct has among the fewest detectives per homicide in the entire city at 1.5, compared to most Manhattan precincts that have anywhere from five to 26 detectives per murder,” The News explains.

“It just seems like his case got swept under the rug,” Rayside told the Daily News. She is offering $8,000 of her own money for information that leads to the arrest of her son’s killer—as she fears police have dismissed her son’s slaying as merely “one black guy against another.”

Silicon Valley’s ‘unbuilt Manhattan’ is best left unbuilt

Silicon Valley’s ‘unbuilt Manhattan’ is best left unbuilt

Over the past two decades, an influx of tech money has sent rents in San Francisco skyward. It’s the fastest growing rental market in the country, with the East Bay’s Oakland coming in second. Last year, landlords in San Francisco used the “Ellis Act” to evict three times as many tenants as they had in 2011, in order to circumvent rent control.

Ken Layne at The Awl harkens back to a simpler time when you could rent a studio in SF for less than $2,400, and compares that to now:

In 2013, the bigger tech companies are still in Silicon Valley, but the people working there—from Mark Zuckerberg to the newest $100K hires straight out of college—want to be in San Francisco. Zuckerberg is a part-timer, with a fancy apartment in the Mission. The rest are part-timers in Silicon Valley, commuting to and from work on immense luxury buses run by Google, Apple, EA, Yahoo and the rest. This has caused problems, notably for San Francisco residents unlucky enough to survive on less than a hundred-grand starting salary. Talk of raising the city’s skyline is met with anger. People argue endlessly over the appropriate comparisons to New York. Is Oakland the Brooklyn to SF? What about Berkeley, or Marin, or the Outer Sunset? And what does that make Bayview or Burlingame?

All of this assumes that urban San Francisco equals Manhattan. It does not. San Francisco, with its leafy parks and charming row houses and distinct villages and locavore restaurants and commuters fleeing every morning to work, is the Brooklyn to an as-yet-unbuilt Manhattan.

To some extent, this is true. Many parts of San Francisco have become bedroom communities for tech workers who take company-sponsored shuttles or hellish Caltrain routes to work many miles south, to a place where rents are cheaper, but the living is decidedly suburban. The youngs making six figures at start-ups seem to prefer the hell of Caltrain to the hell of Silicon Valley suburbia.

Nobody wants to move to the Bay Area for work and then discover they actually have to live in a completely different climate an hour’s drive (without traffic) from the actual bay. The magical part of the Bay Area is really confined to the Bay Area, with its relatively green hills and foggy mornings and cool ocean air.

So Layne proposes building dense, walkable, appealing neighborhoods in the bleak, sprawling stretch between San Francisco and Silicon Valley some 40 miles to the south. “[I]n the post-automobile era, where else would you look to expand your metropolitan area other than the underused sections in the middle of your metropolitan area?”

[T]he areas around and in between the tech giants of Silicon Valley are mostly ready to be razed and rebuilt. There are miles and miles of half-empty retail space, hideous 1970s’ two-story apartment complexes, most of it lacking the basic human infrastructure of public transportation, playgrounds, bicycle and running and walking paths, outdoor cafes and blocks loaded with bars and late-night restaurants. This is where the new metropolis must be built, in this unloved but sunny valley…

With local light rail at street level and express trains overhead or underground, the whole route could be lined with native-landscaped sidewalks dotted with pocket parks and filled on both sides with ground-floor retail, farmers markets and nightlife districts around every station. Caltrain already runs just east of Route 82, and BART already reaches south to Millbrae now.

Alexis Madrigal at The Atlantic calls this “a wisp of a suggestion, an opening statement, perhaps,” but a “fascinating” one.

But as Layne himself notes, people don’t move to the Bay Area because they want to live an hour’s drive south of San Francisco. Even if we brought a Robert Moses-style urban reckoning upon Silicon Valley (an idea that does have its appeal!), why assume the techies would move there?

This is an aggressively naive idea for a region with a dire housing shortage and a serious cultural bias against density. Instead of a Silicon Valley raze-and-rebuild, how about infilling in San Francisco and East Bay cities where young tech workers already want to be anyway? How about rezoning and remaking Oakland and Berkeley’s desolate, unused industrial brownfields along the waterfront? If it can’t be done in the bigger cities, how likely is it to get done in the many suburbs of Silicon Valley? Not likely at all. Much of the Bay Area doesn’t even want more public transportation, let alone more housing density.

Don’t get me wrong, I love the idea of taking a wrecking ball to empty strip malls. But as a Bay Area resident wishing on a star for the region to grow smarter and denser, I see many more worthy routes to take besides bulldozing the ‘burbs, however delicious the thought.

The shells of ocean animals are already dissolving in acidic seas

The shells of ocean animals are already dissolving in acidic seas

Several times over the past months we’ve noted the anticipated effects of ocean acidification. As the atmosphere’s carbon dioxide content increases, some of it mixes with ocean water, forming carbonic acid, lowering the pH of ocean water. Even a slightly more acidic ocean could be enormously damaging to sea creatures, because it also means less of the mineral aragonite that some sea creatures use to form their shells.

National Geographic

We just didn’t really expect it would happen this fast. From New Scientist:

In a small patch of the Southern Ocean, the shells of sea snails are dissolving. The finding is the first evidence that marine life is already suffering as a result of man-made ocean acidification.

“This is actually happening now,” says Geraint Tarling of the British Antarctic Survey in Cambridge, UK. He and colleagues captured free-swimming sea snails called pteropods from the Southern Ocean in early 2008 and found under an electron microscope that the outer layers of their hard shells bore signs of unusual corrosion. …

He visited the Southern Ocean near South Georgia where deep water wells up to the surface. This water is naturally low in aragonite, meaning the surface waters it supplies are naturally somewhat low in the mineral — although not so much so that it would normally be a problem. Add in the effect of ocean acidification, however, and Tarling found that the mineral was dangerously sparse at the surface.

“It’s of concern that they can see it today,” says Toby Tyrrell of the National Oceanography Centre in Southampton, UK.

The state of the world: It is of concern that a terrible thing we expected in the future can be seen today.

How do we save these sea creatures? The way we save ourselves.

The only way to stop ocean acidification is to reduce our CO2 emissions, Tyrrell says. It has been suggested that we could add megatonnes of lime to the ocean to balance the extra acidity. However, Tyrrell says this is “probably not practical” because the amounts involved — and thus the costs — are enormous.

If only there were some animal on Earth that we felt was worth such an expenditure.
