Study: Organic Tomatoes Are Better for You

Remember that Stanford research meta-analysis purporting to show that organic food offers no real health advantages? (I poked some holes in it here). Buried in the study (I have a full copy but can’t post it for copyright reasons) is the finding that organic foods tend to have higher levels of phenols—compounds, naturally occurring in plants, widely believed to fight cancer and other degenerative diseases.

After the study’s release, one of the study’s authors, Dena Bravata, downplayed that result in a New York Times report :

While the difference in total phenol levels between organic and conventional produce was statistically significant, the size of the difference varied widely from study to study, and the data was based on the testing of small numbers of samples. “I interpret that result with caution,” Dr. Bravata said.

A paper published Feb. 20 in PLOS One highlighted the link between organic agriculture and phenols. A team of researchers compared total phenol content in organic and conventional tomatoes grown in nearby plots in Brazil. By cultivating the tomatoes in the same microclimate and in similar soil, the researchers were able to control for environmental factors that might otherwise affect nutrient content.

Farmers markets stand to benefit the poor the most

Farmers markets stand to benefit the poor the most

Farmers markets sometimes get a bad rap for catering to the moneyed set, as though only the well-to-do like to buy their produce in a pleasant, social, outdoor environment, direct from the source.

It turns out that’s all a bunch of compost. Low-income shoppers are actually the real farmers-market power users, buying bigger shares of their groceries at the markets than at other stores compared to middle- and high-income shoppers, according to a new report from the Project for Public Spaces.

The report looked at eight markets across the country in low-income neighborhoods with otherwise broad differences in demographic makeup. “[A]lmost 60% of farmers market shoppers in low-income neighborhoods believed their market had better prices than the grocery store,” the report states.

The main barrier to low-income shoppers patronizing farmers markets? Just basic information. Researchers found that shoppers often didn’t use their food-stamp benefits even though markets accept them, and shoppers didn’t know where markets were or when they were open.

If farmers markets embrace their low-income shoppers and just let them know what’s up, everyone could win.

Hardliners Killed Bush’s Immigration Reform. Can They Stop Obama’s?

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

Last time Washington took a swing at comprehensive immigration reform, the far right went nuts. In 2007, when President George W. Bush joined with leading Democrats to push an immigration package, the bill died in the Senate, the casualty of a GOP base revolt stoked by talk radio and hardline anti-immigration groups. (And, by the way, some Democrats were happy to watch a Bush initiative go down.) Now, after the Senate’s bipartisan Gang of Eight released an immigration reform package and President Barack Obama essentially backed the effort, the looming question is whether opponents of immigration reform can muster the same kind of backlash—and how ready Republican supporters of immigration reform are to fight back.

Carlos Gutierrez was Bush’s secretary of commerce when the 2007 immigration bill crashed and burned. “It was on the one hand talk radio, on the other it was these groups: FAIR and NumbersUSA, Center for Immigration Studies,” Gutierrez says, naming several restrictionist groups founded by anti-immigration activist John Tanton. “We were getting it all over the place.”

"A Killing Machine": Half of All Mass Shooters Used High-Capacity Magazines

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

As lawmakers across the country and in the nation’s capital debate possible restrictions on high-capacity magazines, one question emerges: Are these ammunition feeding devices, which allow a shooter to fire many times without reloading, in fact commonly used by mass killers? We examined the data from Mother Jonescontinuing investigation into mass shootings and found that high-capacity magazines have been used in at least 31 of the 62 cases we analyzed. A half-dozen of these crimes occurred in the last two years alone. (With some of the cases we studied, it remains unclear whether high capacity magazines were used; for more details, jump to our data set below.)

DATA: Explore our mass shootings research

In the shooting that injured Rep. Gabby Giffords in Tucson, Jared Loughner emptied a 33-round magazine in 30 seconds, killing 6 and injuring 13. Inside a movie theater in Aurora, Colorado, James Holmes used 40- and 100-round magazines to injure and kill an unprecedented 70 victims. At Sandy Hook Elementary School in Newtown, Adam Lanza used high-capacity magazines to fire upwards of 150 bullets as he slaughtered 20 kids and 6 adults.

“It turns a killer into a killing machine,” says David Chipman, who served for 25 years as a special agent in the Bureau of Alcohol, Tobacco, Firearms and Explosives. Outlawing high capacity magazines won’t prevent gun crimes from happening, Chipman notes, but might well reduce the carnage: “Maybe three kids get killed instead of 20.”

With Congress undertaking a highly charged debate over firearms restrictions, many observers are skeptical that Democratic Sen. Dianne Feinstein’s proposal to ban assault weapons will garner enough votes on Capitol Hill. But there may be momentum for mandating universal background checks on gun purchasers, and for outlawing the sale of magazines containing more than 10 rounds. A recent NBC News/Wall Street Journal poll found that a majority of Americans support stricter regulation of firearms sales, and 59 percent believe that high-capacity magazines were significantly to blame in the recent spate of mass shootings.

The problem dates back to long before Newtown. In 1984, the assailant who massacred 21 at a McDonald’s in San Ysidro, California, unleashed more than two hundred rounds. School and workplace shootings in Stockton and San Francisco in the late ’80s and early ’90s also involved large magazines, with an estimated 100 shots fired in each case. In 1997, a gunman in Orange, California, fired nearly 150 shots, wielding an AK-47 with a 30-round magazine three years after a federal law banned such assault weapons.

Right-wingers’ dream town is a new urbanist paradise, but full of guns

Right-wingers’ dream town is a new urbanist paradise, but full of guns

Remember this?

This was Glenn Beck’s worst nightmare. Sustainable planned communities were going to destroy our future, he feared.

But over the past few weeks, Beck seems to have had a change of heart. He’s now promoting his own Independence, USA, a “city-theme park hybrid” to be located somewhere in Texas with abundant “craftmen and artisan” small businesses and stores, a working ranch “where visitors can learn how to farm and work the land,” an innovation center, and dedicated mixed-income housing.

Hold on to your hats, though, folks, because Beck is not alone. The dense green community idea is catching on among the right-wing crowd, and these people even use some of Beck’s dreaded key words.

The Citadel, a sort of castle-themed survivalist compound planned for the eastern mountains of Idaho, will have a dense town center and farmers market. The fortress aims to protect residents in part by “physical preparedness to survive and prevail in the face of natural catastrophes — such as Hurricanes Sandy or Katrina.” Calling all green-minded fans of The Games of Thrones: Homes will be made of poured concrete “for exceptional durability,” and may have those cute little windows for shooting arrows out of.

However, the website declares:

Marxists, Socialists, Liberals, and Establishment Republicans may find that living within our Citadel Community is incompatible with their existing ideology and preferred lifestyles.

It’s kind of not though — the design hews pretty close to the core tenets of smart growth. But it also kind of is, because the Citadel’s main purpose is “preservation of liberty,” i.e. having all of the guns.

Not sure which eco-friendly neo-libertarian planned community to choose? Gawker has a breakdown of each community’s salient points, and declares Independence the winner (maybe because Beck also plans to include that theme park).

Has everything you thought you knew about political ideologies and lifestyles been destroyed now? I’m sorry. But if the right is going to run away to delusional Disneylands, they might as well be dense and livable, right?

And if they’re going to fill those places with guns and plop them in the boonies way the hell away from the rest of us, I’m not complaining.

Roe: The Next 40 Years

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

Last Tuesday marked the 40th anniversary of Roe v. Wade, the Supreme Court decision that affirmed a constitutional right to abortion in the United States. As the case heads into middle age, a new survey from the Pew Forum on Religion & Public Life found that only 44 percent of people between the ages of 18 and 29 could correctly identify what Roe was even about.

But survey results like that one only tell part of the story. The fact that many young adults can’t correctly identify a particular Supreme Court case shouldn’t be taken as a sign that Millennials—the generational term commonly used for anyone between the ages of 18 and 30—don’t care about reproductive rights. (After all, some of our elected officials can’t identify any Supreme Court cases.) Millenials’ actual beliefs about abortion policy matter more than their ability to identify Roe. On that subject, the poll results are clear: 68 percent of 18 to 29-year-olds believe that women should have a right to access abortion—the highest support in any age bracket other than the baby boomers.

Roe: The Next 40 Years

Nearly half of new U.S. power capacity in 2012 was renewable — mostly wind

Nearly half of new U.S. power capacity in 2012 was renewable — mostly wind

As predicted, almost half of the new power-generating capacity installed in the United States last year was renewable.

The Federal Energy Regulatory Commission recently released its December update on the nation’s energy infrastructure [PDF]. When we last checked on the data, it suggested that some 46 percent of new capacity — January through October — was renewable. Well, that ratio improved over the last two months of the year. Ultimately, 49.1 percent of new capacity was renewable.

Compare that to 2011, when less than 40 percent was renewable.

GreenBiz.com explains that end-of-year boost.

The latest Energy Infrastructure Update report from the Office of Energy Projects, part of the Federal Energy Regulatory Commission (FERC), lists just shy of 13GW of green energy projects coming online last year, a more than 50 percent rise on the 8.5GW of capacity added in 2011.

Around a quarter of this capacity became operational in December alone, as wind energy developers rushed to complete projects before the feared expiration of federal tax credits.

We noted last September the furious rush to bring those projects to completion. Seems like it worked.

The FERC report breaks out the new capacity by type.

Wind ended up being the biggest new source of capacity, beating even natural gas (which itself had a pretty good year).

The question is: Can this pace be sustained into 2013? The tax credit was extended as part of the fiscal cliff deal, but only temporarily. Our David Roberts thinks 2013 will be another big year for the industry. It will certainly be better than it would have been without the extension — but we’ll have to wait 12 months to see if Roberts is right.
