Food, Inc.

I just discovered that the documentary Food, Inc. can now be watched online at the PBS website. From the PBS companion website:

In Food, Inc., filmmaker Robert Kenner lifts the veil on our nation's food industry, exposing the highly mechanized underbelly that's been hidden from the American consumer with the consent of our government's regulatory agencies, USDA and FDA. Our nation's food supply is now controlled by a handful of corporations that often put profit ahead of consumer health, the livelihood of the American farmer, the safety of workers and our own environment. We have bigger-breasted chickens, the perfect pork chop, insecticide-resistant soybean seeds, even tomatoes that won't go bad, but we also have new strains of E. coli — the harmful bacteria that causes illness for an estimated 73,000 Americans annually. We are riddled with widespread obesity, particularly among children, and an epidemic level of diabetes among adults.

Among the experts interviewed is Michael Pollan. Last year we listened to the audio version of his excellent, accessible book, In Defense of  Food.

I've had the DVD on reserve at the library forever (my request has already expired once), so I'm very glad to see that we can now watch it on demand. Now if we can only figure out how to stream video from the computer to our ancient TV...

Stuffed Triops and other Fun Critters

A Cool Article on Aquaponics

When we brought the goldfish in from the plastic pond in the backyard last fall, they had doubled in size. So we picked up a second tank to keep them in. Our tanks are self-contained: rocks, plants and fish in their own ecosystem, without filters. (We change half of the water and wipe the tank down every week.)

At one point we gave a thought to putting at least one of the 10-gallon tanks on the shelf by the back sliding door, where we had our hydroponic set-up last year, and trying to grow veggies on the top of it. We never followed through. (As a side note, for the first time in my experience the boxes of dirt-planted herbs I brought in last fall are still doing going strong indoors this winter.)

However, this New York Times story describes an aquaponic experiment very similar to what we were thinking about. Given how wet our property is, we don't need to grow in tanks year-round, but maybe we'll give it a try next winter.

Brain Slices

As I write this, you can watch live streaming video of a frozen brain being sliced into sections for study at the Brain Observatory at the University of California, San Diego. The brain belongs to a man who lost his short-term memory after an operation to help his seizures.

From CNN:

A camera is taking a picture of each individual slice, and these pictures will also be made available on the Web. The goals are to map the human brain in new ways and correlate individual structures with specific functions such as memory.

Nature Art -- Big and Small

I finally got the chance to interview (via email) local nature writer/illustrator Carol Coogan. Read "How to Get Your Kids Out Drawing Nature" on GeekDad.

And The Micropolitan Museum of Microscopic Art Forms is a website featuring images of teeny tiny organisms. Here's their description:

For several centuries artists have depicted the human figure, still-lives, landscapes or non-figurative motifs. One subject has been widely neglected all those years: Micro-organisms!

The Micropolitan Museum finally exhibits these often overlooked works of art which are only visible with the aid of the microscope. Curator Wim van Egmond has collected the finest microscopic masterpieces nature has ever produced during eons of natural selection.

Great Kids Book about Triops

Photographer Lori Adams sent me
a review copy of the new book she produced with author Helen Pashley about triops. This book is the reference you'll need when you try raising these frisky little critters for yourself. It has all the information you'll need, plus lots of clear, well-marked photos so you can identify what you're seeing. I recommend it highly. Order it through Little Science books.

You can also order triops kits through Amazon or directly from Triassic Triops (but I get a small kickback from Amazon, and shipping is free)!

See my post about triops on GeekDad. The comments are pretty funny, too.

Charlie's Playhouse - Toys that Teach Evolution

Thanks to my fellow GeekDad writer Jenny for pointing me towards Charlie's Playhouse, a toy company dedicated to games and learning tools about evolution. As Jenny writes:

The 24th of November is the 150th anniversary of the publication of Charles Darwin’s work, “On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.” To celebrate this important anniversary, Charlie’s Playhouse, maker of evolution-inspired toys, play things and apparel, is inviting us all to ask our kids (age 4 to 10), “What is evolution?” They are hoping this will spark family discussion about evolution.
