Icebergs in the Antarctic area sometimes have stripes, formed by layers of snow that react to different conditions.

Blue stripes are often created when a crevice in the ice sheet fills up with meltwater and freezes so quickly that no bubbles form.

When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe.

Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.

Salamanders can regrow limbs after they are torn off; why can’t humans do the same?

Many years ago studies in the laboratory of our colleague Susan V. Bryant at the University of California, Irvine, demonstrated that the cells in the blastema are equivalent to the cells in the developing limb bud of the salamander embryo. This discovery suggested that the construction of a limb by the blastema is essentially a recapitulation of the limb formation that took place during the animal’s original development. An important implication of this insight was that the same genetic program is involved in both situations, and because humans make limbs as embryos, in principle we should already have the necessary programming to regenerate them as adults, too. It seemed, therefore, that all scientists needed to do was figure out how to induce an amputated limb to form a blastema.

The April issue of Scientific American looks at research that may one day lead to self-regeneration of human body parts. Link -via Digg

Thousands of sheep died one night in 1968 in Skull Valley, Utah. Army officials got busy drafting a denial. They had been testing Cold War chemical and biological weapons, one of which was called VX.

VX was a triumph among the biological warfare community. Odorless and tasteless, it's three times as toxic as Sarin. In initial trials, this over-acheiving compound was also found to be highly stable, enabling long shelf life and environmental persistence. VX works by blocking chemicals in the victim's body from functioning. It prevents the enzyme acetylcholinesterase from allowing muscles to relax, resulting in the contraction of every muscle in the body. Exposure to a minute or diluted dose of VX will cause muscle twitching, drooling, excessive sweating, and involuntary defecation, among other unpleasantries. Exposure to a lethal dose — about ten milligrams — will cause convulsions, paralysis, and eventually asphyxiation due to sustained contraction of the diaphragm muscle. Unless the affected skin is cleaned and an antidote is administered immediately, a single drop of liquid VX will kill a person in around ten minutes

The sheep were not the only animals who died near the Dugway Proving Grounds. Read the rest of the story at Damn Interesting. Link

One owl has a repertoire of responses to different threats. He can make himself big, make himself small, or just ignore the enemy. Although he was in no real danger, I felt sorry for the little guy. -via Everlasting Blort

Peter Kelly reponded to the post about rattlesnake vodka with this photograph he took in Vietnam. The caption reads

These are artistically arranges snakes in bottles of liquor. People drink this. Really.

Link -Thanks, Peter!

The Texas Alcoholic Beverage Commission seized an unusual cache of vodka at a rattlesnake farm in Palo Pinto County. The 411 bottles each contained not only vodka, but also a ten-inch rattlesnake! Sgt. Charlie Cloud said he’s never seen anything like it.

TABC officials said alcohol containing snakes or scorpions is popular in Asian cultures. An Internet search found operations selling Thai scorpion vodka, cobra whiskey, giant centipede whiskey, herbal gecko lizard wine and Mekong River eel wine.

"It's very bizarre," Cloud said. "We learned that these are believed to contain aphrodisiac properties. We heard that some people believe having a venomous animal creates hallucinations."

TABC agents received a tip several weeks ago and sent an undercover agent to the rattlesnake ranch to purchase the vodka. It wasn't on display.

"We had to go in and ask for it," Cloud said.

Bob Popplewell, the owner of Bayou Bob's Brazos River Rattlesnake Ranch, is expected to face charges of selling alcohol without a permit. http://www.star-telegram.com/275/story/530369.html -via Arbroath

Member of Parliament Tommy Tabermann has proposed that the four weeks of annual vacation in Finland be expanded to include a 7-day “love vacation” to strengthen relationships.

According to Tabermann, the purpose of such vacations would be to prevent relations from disintegrating and the spouses from drifting apart.
During the seven days, couples could devote themselves to each other ”both at an erotic and emotional level” and ”find their way back to the path of love in order to find the wellspring of love again”.
Some MPs suspected that the proposal might discriminate against single persons, but others said that a love vacation would be the privilege of all, even the singles and the single parents.

The proposal was sent to committee for study. http://www.hs.fi/english/article/Finnish+Parliament+debates+proposal+for+love+vacations+/1135234799696 -via Boing Boing

Lacey Henderson’s right leg was amputated when she was nine years old due to a tumor in her kneecap. But at her mother’s suggestion, she tried out to become a cheerleader in high school. Not only did she make the team, but she worked her way up to captain! Now she’s 18 and cheers for the University of Denver.

She says sometimes she blends in and people don't even notice her leg. Of course, the stickers on the side usually give it away.

"Sometimes you just have to own having one leg and you can't be afraid to show it," she said. "My parents would get so mad at me and say 'Lacey, it looks just like a tattoo!'"
