The BPA Saga Continues…

With something somewhere between disgust and resignation, I must report to you that BPA, the ambiguously-toxic (or is it safe?) wonder chemical found throughout our plastics and thus our bodies, is once again back in the news (more...)...

BPA Receipts

Here’s another way that most ubiquitous of not-so-friendly chemicals, BPA, can end up in your body: via store receipts. Turns out that the thermal papers used to print most receipts are heavily infused with the chemical (up to 2% by weight, apparently). Tests have revealed that the BPA easily rubs off on your fingers as (more...)...

BPA in the NY Times

NY Times columnist Nicholas Kristoff writes about the ubiquity of BPA in our bodies, plus a gaggle of new studies linking BPA exposure to a variety of abnormalities in test animals. If you’ve been following the BPA Saga (including this impressive bit of corporate nastiness by Sigg), you’ll see that the latest research keeps upping (more...)...

Hypoxic Interval Training?

I was reading an article in this month’s Backpacker magazine about thirteen-year-old Jordan Romero, who is on a quest to be the youngest person ever to climb the so-called Seven Summits. While there’s certainly no lack of controversy about Jordan’s story (he summited Aconcagua at 11, and has plans to top Everest next year), what (more...)...

Sunscreen in a Pill?

For fair-skinned persons like myself, it’s sort of the Holy Grail of sun protection: the concept of a sunscreen that you ingest as a pill rather than slather all over your body. Interestingly enough, one of my parents’ health newsletters is mentioning a product called Heliocare which promises to do exactly that. It’s a pill. (more...)...

Female Athletes and ACL Tears

The New York Times is running an article on the epidemic of ACL tears and other injuries in U.S. female athletes. Female participation in sports in this country is exploding, credited in part to a 1972 law, TITLE X, which mandated equal opportunity in sports to female athletes (more...)...

How Toxic is Your Sunscreen?

If you’re like me—fair-skinned, that is—you’ve probably discovered that sunscreens don’t all perform the same. I can put on a thick layer of SPF 50 and still get torched. No, it’s not just that sunscreens tend to wash off as you sweat: some just don’t work that well. Many formulations only give SPF ratings for (more...)...

Backcountry Skiing & Risk

After a long road trip to the San Juans, we’re back in dry SoCal, looking at bare mountains and searching the web for diversions. There’s an interesting American Alpine Club Article on Risk in which the author argues that climbing and mountaineering accidents have dropped dramatically despite a huge increase in participants. Mountaineering, of course, (more...)...

National Geographic Returns to Chernobyl

We’ll stay a little off topic for the day, I guess. If you’ve found the Ghost Town/Kid of Speed entry on my links page, you may have guessed I’m fascinated with Chernobyl, site of the world’s worst nuclear accident. In the April issue, National Geographic Magazine returns to the site of the disaster 20 years (more...)...
