Ask Your Weird Animal Questions: Alligators and Regenerators

A reader wanted to see more regenerating animals - one of my favorite subjects - and in Ask Your Weird Animal Questions: Alligators and Regenerators, you can see links to other pieces I've done on this subject and check out Hydractinia enchinata, an amazing little regenerator which lives in colonies like the one being escorted around by this hermit crab. Cool stuff, plus I got to talk to Dr. James Sikes of University of San Francisco, an amazing scientist who spurred regeneration in a species of flatworm who had lost that ability by changing the activity of a single gene in the worm. The word 'awesome' gets used a lot but that truly is.

Save Them All: A trip to Best Friends Animal Society in Utah

Image
"Would you like to go where you've always wanted to go and do one of your favorite things ever?" That's not how the press trip to Best Friends Animal Society sanctuary in Angel Canyon, Utah was put to me, but that's how I heard it. I've long wanted to see Utah and Best Friends held the promise of playing with dogs. And cats. And seeing horses, goats and probably a few other things that were on your See-and-Say: The Farmer Says. Animals never lose their magic.  This was one of the most magical trips I've ever been on (and I've been to the Playboy Mansion). I'm working on my story for Alternet right now; this is photo companion for pics of the things I talk about in that. I may post more on other aspects of the journey. Wait. I just got it. That's what was different. This wasn't a trip. It was a journey, one I hope as many people get to go on as possible.  Above: Pima learning about cameras from Melissa Miller in puppy social...

Buy my book: Crazy Little Thing: How Love and Sex Drive Us Mad

Image
       Carl von Cosel installed a phone in his dead wife's tomb so they could chat - he eventually just took her home.      Burt and Linda Pugach married after he did a prison sentence for sending thugs to 'scare' her and they blinded her with acid.     Love makes us all feel insane. If it hasn't knocked you on your ass you haven't been in it.       I wrote Crazy Little Thing: Why Love and Sex Drive Us Mad several years ago because I wanted to understand why romantic problems had such a stranglehold on me and how people's greatest happiness, the thing we all want, could lead to them killing each other. It was published by Viva Editions just before the explosion of true crime shows like Wives with Knives and Who the Bleep Did I Marry?      My hope for the book has always been that the interviews with everyone from psychologists to felons would help people understand themselves but also that it would be a...

Say Ahhhhh: Drive-Thru Pap Smears in the COVID era

Image
        Listening to my friends talk about the COVID-19 test I thought it was going to feel like getting a lobotomy.      “They stick a swab so far up your nose, I felt like it was going into the back of my eye,” one said, but when free drive-through testing was offered in my little Florida beach town I went. I can pinch a penny until Lincoln starts crying and if something is free, I’m going to get one, even if it means being skewered like a corn dog.  The test was mildly irritating. You tilt your head back and they do, indeed, poke a swab up your snoot farther than you’d expect it to go. It felt like I’d been bike riding and got ladybug stuck up my nose, a sensation which lasted about 45 minutes after the actual sticking. It wasn’t as bad as I anticipated, but I’d anticipated getting my eyeballs yoinked out through my nostrils.  Anything else was emotional found money. What left a more lasting impression than the test was ...
