Made from an fMRI scan I had done. Goes from the top of my brain straight through to the bottom. That little dot that appears for a second on the upper-left hand side is a vitamin E pill they taped to the side of my head to make sure they didn't accidentally swap the L-R orientation.
To clarify, this animation was made by Fastfission and is based on Fastfission's brain. This is what makes a Wikipedian tick. -- Solipsist

A fishing spider in the family Pisauridae and genus Dolomedes with two of its legs missing. Most likely some predator (a bird or given its habitat a large fish or frog) grasped the spider by the missing limbs which were jettisoned by the spider in response. Taken in Swifts Creek, Victoria, Australia in April 2007

Citrus fruits
More than 70 percent of all citrus fruits grown in the United States are varieties developed by the ARS citrus breeding program.
In Florida, the ARS has developped citrus varieties that are higher yielding with increased disease resistance, better color, and longer shelf life. A major success story is Ambersweet, a cold-hardy citrus that's been approved for use in orange juice products. Because it withstands Florida's occasional cold snaps that can ruin most citrus, Ambersweet is being widely planted in the Sunshine State. It took 20 years of patient breeding to develop it, but the payoff is huge.
If there's usually a grapefruit in your shopping cart, you may already have met up with a favorite ARS-created variety. It's a red-fleshed, thin-skinned, seedless grapefruit that was developed and released in 1987. Since then, over 4 million Flame nursery trees have been propagated in Florida. No other grapefruit variety has ever been so widely accepted and planted.
Orange sections can now be prepared by a patented ARS process that uses commercially available food-grade enzymes. The process also removes the bitter white portion of grapefruit peel, eliminating hand-peeling and allowing more precise portion control. And the prepeeled fruit is ideal for school lunch programs and restaurants.
