An Arctic storm tore a drilling rig loose from its tow ship and forced it aground near Alaska's Kodiak Island this week. Just a few months ago, the rig and another began preliminary drilling of the first offshore oil wells in the Arctic. Shell's efforts to drill in the Beaufort and Chukchi Seas have been plagued by problems. But that's just part of the cost of doing energy business in this new era. Consider drilling rig operator Transocean, which agreed to pay the U.S. government $1.4 billion this week for its part in the disastrous three-month long blowout in the Gulf of Mexico in 2010. Meanwhile, the thirst for oil drives the mining of tar sands in Alberta and the flooding of old wells with steam or CO2 in California and Texas. And, of course, there's the accelerating accumulation of greenhouse gases in the atmosphere from all that fossil fuel burning. The resulting climate change is part of what makes drilling for oil offshore in the unfreezing Arctic possible, just as it has opened once mythical shipping routes such as the Northwest and Northeast Passages. That's a positive feedback loop with negative consequences

It’s a given that most babies wear diapers, in western cultures anyway. But diapers may trap more than waste—they may also confine a baby’s to walk. Scientists compared the walking gaits of 60 babies who were either naked, wore a thin disposable diaper or a thick cloth diaper. Half the babies were 13-month-old novice walkers and the other half 19-month-old walkers.When the 30 13-month-olds walked naked only 10 fell, but while wearing the cloth diaper 21 of them fell, and while wearing the disposable 17 of them fell.Among the 19-month-olds only four fell while naked or wearing disposables, while eight fell when wearing cloth diapers. But both age groups took wider and shorter steps while wearing diapers as to walking naked. The research is in the journal Developmental Science, the study cannot predict if wearing diapers has a long-term impact. Nonetheless, the researchers believe walking naked would speed up walking . But then we are left with the issue of covering the entire house in plastic and relying heavily on the child’s ability to his or her elimination intentions.
