They don’t go well together

I've been meaning to write about a recent story in Time on risk perception -- in particular, on how badly we suck at it.

The basic theme is familiar by now:

We pride ourselves on being the only species that understands the concept of risk, yet we have a confounding habit of worrying about mere possibilities while ignoring probabilities, building barricades against perceived dangers while leaving ourselves exposed to real ones.

And the culprit is also well-identified: a nervous system that evolved in radically different circumstances. Thanks to a jumpy little clump of tissue called the amygdala, nestled right above the brain stem, humans are finely tuned to short-term dangers. Snakes in the grass, glowering faces -- these things stimulate the amygdala and prompt a fight-or-flight squirt of hormones. That's how we survived on the savanna.

Science magazine weighs in

Yesterday I came across a head-turning new biofuels study by researchers at the University of Minnesota that found that planting a mixture of native grassland perennials produces biofuels more efficiently than corn and soybeans (no surprise) and even more efficiently than any single-grass plots (hmm, interesting).

Consumer Reports finds chicken riddled with bacteria

I didn't catch this two-day-old story until now, but it's causing me to reheat my homemade chicken broth to boiling. Consumer Reports found a stunning 83 percent of all chickens it tested harbored campylobacter or salmonella, the leading bacterial causes of foodborne disease. And that was up from 49 percent of chickens tested just three years ago.

Even more troubling, it found much of the bacteria was resistant to antibiotics. Why is this an issue? Because the Centers for Disease Control estimates 40,000 people get sick and 600 die each year from salmonella. Campylobacteriosis is estimated to affect over 1 million persons every year, or 0.5% of the general population.

Movie, music bring awareness to conflict gems

A diamond is forever. A diamond is a girl's best friend. Lucy in the sky with diamonds. Neil Diamond.

Call it bling, call it ice, call it the most beautifulest piece of sparkly you've ever seen and yes-yes-yes-I'll-marry-you. Diamonds are more than just super-polished rocks. They symbolize true love and economic status. They adorn everything from ring fingers to pierced ears, gangsta grillz to bra straps.

But a recent string of films, music, and media coverage is beginning to shed light on the, shall we say, less-than-sparkling reputation of the industry that produces these gems. The New York Times has even called it "Hollywood's multifaceted cause du jour."

A new UN report

Bjorn Lomborgian FUD aside, it's becoming clearer and clearer that protecting the environment is not an alternative to fighting poverty and disease, but a necessary prerequisite. The latest bit of evidence comes in a new UN report:

The key Millennium Goal of halving poverty in a decade cannot be met without better environmental protection, according to a new report.

Silicon Valley investor Vinod Khosla chats about the promise of ethanol

Venture capitalist and ethanol booster Vinod Khosla. Billionaires are piling onto the biofuels bandwagon. Bill Gates is doing it. Richard Branson is doing it. The Google guys are doing it. Less well-known is the billionaire who kicked off the whole trend: Vinod Khosla, a cofounder of Sun Microsystems and former partner with Kleiner Perkins, the […]

From Prince to Prints

An interview with David Pimentel

Any worthy idea can withstand and even be improved by naysayers; scolds and skeptics play the useful role of pointing out obvious flaws. The biofuels industry has no more persistent, articulate, and scathing critic than David Pimentel, professor emeritus of entomology at Cornell University. David Pimentel.

Three perspectives on the biofuels debate

Imagine how amazing petroleum must have seemed back when it was an emerging alternative fuel in the U.S. Drill a hole in the ground in some parts of Texas and Pennsylvania, and rich black stuff would come gushing up, loaded with energy. What could possibly be the problem with such bounty? In some quarters, biofuels […]
