cannibalize their littermates in the womb. "While 12 littermates may start out the journey, all but one is devoured
by the biggest in the pack. That strategy allows sand tiger sharks to

If you are adorned with a tattoo, or are interested in such,

In a masterful
Rolling Stone article, Matt Taibbi explains how the rigging of Libor rates was the biggest price-fixing scandal of all time.
You may have heard of the Libor scandal, in which at least three – and
perhaps as many as 16 – of the name-brand too-big-to-fail banks have

they move three legs, then they move three other legs, would that sound nonsensical? But it's true, and the linked gif shows why it is totally logical and practical.
They are basically using moving tripods. You learn something every day.
The photo is our first butterfly of the year. Mourning Cloaks (Camberwell Beauties) (Nymphalis antiopa) are typically the first because they are able to overwinter through the sub-zero temperatures. They come out with ragged wing edges (from last autumn's adventures) and hungry. Since no nectar sources are available in Wisconsin in April, they seek tree sap (or overripe fruit at the homes of butterfly enthusiasts).
