LOS ANGELES — A couple of dozen electric cars with fuel cells under the bonnet (in place of the more usual flat-pack of batteries beneath the floor) have been zipping around your correspondent’s neighbourhood for the past few years. Most are FCX Clarity models from Honda, all in the same rich crimson colour. A couple of others are silver F-Cell station wagons made by Mercedes-Benz. These experimental vehicles are leased to selected users for trial periods while their manufacturers see how the hydrogen-fuelled cars survive the cut and thrust of Los Angeles’ traffic.

So far, most seem to have acquitted themselves rather well. Meanwhile, their drivers can feel rightly smug about the only emission from the exhaust pipes being water vapour. Another plus is that the fuel-cell vehicles are largely free of the ‘range anxiety

GMO Opponents Are the Climate Skeptics of the Left,’ declares the headline of a recent piece by Keith Kloor in Slate. The argument goes like this: Just as certain conservative writers flout science by denying the urgency of climate change, there are progressive writers-he named me as a prominent example-who defy an alleged scientific consensus by criticizing the genetically modified crop industry. We’re hypocrites, the charge goes, because we thunder against the denial of good science when it comes to climate, but indulge in denialism when it comes to GMOs.

I think Kloor’s critique is nonsense. Sure, there are wackos who campaign against GMOs, but not all GMO critique is wacko. In a 2009 roundtable in Seed Magazine, I debunked the idea that there’s a scientific consensus around GMOs analogous to the one around climate. I also ruminated on that theme in this 2009 review of Michael Specter’s book Denialism. I plan to return to the theme of scientific consensus and GMOs soon, but to make a long story short, I’ll quote my Seed piece:

The consensus around climate change developed in spite of a multi-decade campaign by some of the globe’s most powerful and lucrative industries-the petroleum […]

An early childhood surrounded by books and educational toys will leave positive fingerprints on a person’s brain well into their late teens, a two-decade-long research study has shown.

Scientists found that the more mental stimulation a child gets around the age of four, the more developed the parts of their brains dedicated to language and cognition will be in the decades ahead.

It is known that childhood experience influences brain development but the only evidence scientists have had for this has usually come from extreme cases such as children who had been abused or suffered trauma. Martha Farah, director of the centre for neuroscience and society at the University of Pennsylvania, who led the latest study, wanted to find out how a normal range of experiences in childhood might influence the development of the brain.

Farah took data from surveys of home life and brain scans of 64 participants carried out over the course of 20 years. Her results, presented on Sunday at the annual meeting of the Society for Neuroscience in New Orleans, showed that cognitive stimulation from parents at the age of four was the key factor in predicting the development of several parts of the cortex – the layer of […]

Wall Street’s involvement in the charter school movement is presented as an act of philanthropy, but it’s really about greed.

The end of the Chicago teachers’ strike was but a temporary regional truce in the civil war that plagues the nation’s public schools. There is no end in sight, in part because — as often happens in wartime — the conflict is increasingly being driven by profiteers.

The familiar media narrative tells us that this is a fight over how to improve our schools. On the one side are the self-styled reformers, who argue that the central problem with American K-12 education is low-quality teachers protected by their unions. Their solution is privatization, with its most common form being the privately run but publicly financed charter school. Because charter schools are mostly unregulated, nonunion and compete for students, their promoters claim they will, ipso facto, perform better than public schools.

On the other side are teachers and their unions who are cast as villains. The conventional plot line is that they resist change, blame poverty for their schools’ failings and protect their jobs and turf.

It is well known, although rarely acknowledged in the press, that the reform movement has been financed and led […]

Voter IDs laws have become a political flashpoint in what’s gearing up to be another close election year. Supporters say the laws - which 30 states have now enacted in some form - are needed to combat voter fraud, while critics see them as a tactic to disenfranchise voters.

We’ve taken a step back to look at the facts behind the laws and break down the issues at the heart of the debate.

So what are these laws?

They are measures intended to ensure that a registered voter is who he says he is and not an impersonator trying to cast a ballot in someone else’s name. The laws, most of which have been passed in the last several years, require that registered voters show ID before they’re allowed to vote. Exactly what they need to show varies. Some states require a government-issued photo, while in others a current utility bill or bank statement is sufficient.

As a registered voter, I thought I always had to supply some form of ID during an election.

Not quite. Per federal law, first-time voters who registered by mail must present a photo ID or copy of a current bill or bank statement. Some states generally advise voters […]
