It may not look like much, but together with other tracks in the 280 million-year-old rocks of Prehistoric Trackways National Monument in southern New Mexico, this vague form has been identified as the one and only fossil impression of a scorpion body ever found. The scorpion rested here for a time, then scurried off, and the imprint of its body eventually turned to stone.

The age of the trace fossil, as body impressions and tracks are called, takes scorpions way back to the early Permian. That confirms that scorpions have survived a lot of gigantic mass extinction events between then and now. What’s more, seeing how the carbon dioxide levels in the Permian atmosphere were probably three times what they are today on Earth, it’s not likely anthropogenic climate change will stop these hardy arthropods either.

‘We gave it the name Alacranichnus, which means scorpion trace.’

– Spencer Lucas, curator at the New Mexico Museum of Natural History and Science

“We gave it the name Alacranichnus, which means scorpion trace (alacran is Spanish for scorpion and ichnos is Greek for trace),” said Spencer Lucas, curator at the New Mexico Museum of Natural History and Science (NMMNHS). The discovery was just published in the journal Ichnos: An International Journal for Plant and Animal Traces by scientist at the museum in Albuquerque.

In the paper Lucas, Allan Lerner and Sebastian Voigt describe the trace fossil as a “substantial addition to the poorly known Permian fossil record of scorpions that demonstrates that scorpions were present in the Early Permian coastal plain…. Unfortunately, there is nothing in the way of morphological characters evident from the resting trace that can help determine which particular type of scorpion made it.”

Scorpions are the oldest known arachnids, the researchers explain, with some fossils of probably aquatic scorpions dating back to the Silurian Periods about 430 million years ago. Later, in the Carboniferous (359 million to 299 million years ago), scorpions took to land. But then the fossils peter out.

“There is an extremely large gap in the North American scorpion fossil record following the Upper Carboniferous,” write Lucas and his colleagues. In fact, Permian scorpion fossils are rare worldwide, and only found in bits and pieces. There are no more North American scorpion fossils until the Middle Eocene (about 45 million years ago).

The unique new fossil will be displayed in the New Mexico museum’s upcoming Paleozoic Hall.

He’s going to need a bigger bite.

According to CBC.ca, two Newfoundland men saved a shark from choking on a moose.

Derrick Chaulk was driving by the Norris Arm North harbor and thought he saw a beached whale. But when he went closer to investigate, Chaulk realized it was a Greenland shark.And it was choking.

“[The moose] had the fur and all the liner on it — it was about 2 feet long, maybe,” Chaulk said.

Chaulk and another man, Jeremy Ball, started pulling on the moose, CBS.ca reported.

“A couple yanks and it just came right out,” he said.

Chaulk and Ball then pushed the shark back into the water. After being still for a few minutes, water starting coming off the shark’s gills and it headed back out to sea.

“It was a good feeling to see that shark swim out, knowing that you saved his life,” Chaulk said. “There was a few people up on the bank watching and once that shark swam out and lifted his tail, and then swam all the way out, everybody just clapped.”

Greenland sharks are rarely seen on the northeast coast of Newfoundland, CBC.ca reported.

Wine cellar found in ancient palace

Raising Canaan? Wine cellar found in ancient palace hints at a sophisticated drink for banquets

NEW YORK –  Scientists have uncovered a 3,700-year-old wine cellar in the ruins of a Canaanite palace in Israel, and chemical analysis shows this is where they kept the good stuff.

Samples from the ceramic jars suggest they held a luxurious beverage that was evidently reserved for banquets, researchers said.

“It’s not wine that somebody is just going to come home from a hard day and kick back and drink,” said Andrew Koh of Brandeis University. He found signs of a blend of ingredients that may have included honey, mint, cedar, tree resins and cinnamon bark.

The discovery confirms how sophisticated wines were at that time, something suggested only by ancient texts, said Eric Cline of George Washington University. He, Koh and Assaf Yasur-Landau of the University of Haifa in Israel spoke to reporters Thursday before their work was presented Friday at a meeting of the American Schools of Oriental Research.

The wine cellar was found this summer in palace ruins near the modern town of Nahariya in northern Israel. Researchers found 40 ceramic jars, each big enough to hold about 13 gallons, in a single room. There may be more wine stored elsewhere, but the amount found so far wouldn’t be enough to supply the local population, which is why the researchers believe it was reserved for palace use, Cline said.

The unmarked jars are all similar, as if made by the same potter, Yasur-Landau said. Chemical analysis indicates that the jars held red wine and possibly white wine, Koh said. No liquid was left, and he analyzed residues he had removed from the jars.

Patrick McGovern of the University of Pennsylvania, an expert in ancient winemaking, said the discovery “sheds important new light” on the development of winemaking in ancient Canaan, from which it later spread to Egypt and across the Mediterranean. He said the chemical analysis would have to be published before the ingredients of the wine could be assessed.

Curtis Runnels, an archaeologist at Boston University, called the finding significant not only in showing the sophistication of the wine, but also in suggesting that it was meant specifically for palace use. He noted that the chemical analysis showed each jar held wine from the same recipe, showing the “consistency and control you’d expect in a palace.”

ORIGINALITY IN MARKETING: THE TOP 20 “STREET” ADVERTISEMENTS

ORIGINALITY IN MARKETING: THE TOP 20 “STREET” ADVERTISEMENTS

Sometimes invasive and annoying, urban marketing does has the potential to be innovative in how the city’s objects are used to convey a message.

BY FLOYD (TOPITO) ON JANUARY 27, 2011

There is something interesting about ads that creatively take advantage of urban space (notably from Julian Beever’s optical illusions). Clearly this domain sparks the imagination and gives way to endless innovations. This list is devoted to streets and restricts the art to the ground, further cultivating an appreciation for urban space.

2-A musical crossing

3-An orthodontist can straighten that out

4-The South African tourism office

5-The pedestrian crossing bar-code

6-NGO Aseema for children’s rights

7-Mr. Clean makes it whiter

8-McDonald fries tries to take over the world

11-A hot cup of coffee…


12- The promotion for the children’s books “The Kids Who Could Fly”

13-Fedex’s office supplies

14-Durex condoms: with “knobs” :-)

First 3D-printed metal gun

Texas firm makes world’s first 3D-printed metal gun

By Konrad Krawczyk

    Components for the first ever working 3D Printed metal gun. (SOLID CONCEPTS)

Depending on who you are, where you hail from, and where you stand on guns, 3D printing and related issues, this bit of news will either thrill and astound you, terrify you, or compel you to say “meh.”

But here goes: A company by the name of Solid Concepts has made the world’s first metal gun using a 3D printer.

Based out of Austin, Texas, the 3D-printed metal pistol made by Solid Concepts is based on the Browning 1911 firearm. Solid Concepts set out to make this gun in an effort to prove that they can make weapons that are fit for “real world applications.”

‘The industrial printer we used costs more than my college tuition (and I went to a private university).’

– Solid Concepts representative Alyssa Parkinson

To make the gun, Solid Concepts utilized a manufacturing process known as direct metal laser sintering, or DMLS. DMLS is a 3D manufacturing process used to make metal parts for the aerospace and medical industries. The application for DMLS in the latter example is specific to surgical tools, meaning it’s perfectly suited for the creation of precision firearms.

“The whole concept of using a laser sintering process to 3D Print a metal gun revolves around proving the reliability, accuracy, and usability of 3D Metal Printing as functional prototypes and end use products,” says Solid Concepts’ vice president of additive manufacturing Kent Firestone. “It’s a common misconception that laser sintering isn’t accurate or strong enough, and we’re working to change people’s perspective.”

While 3D printers are becoming more and more affordable all the time, don’t get the wrong idea: you can’t just slap down a couple thousand bucks for a MakerBot 3D printer and hope to make your own firearm from the comfort of your own garage.

“The industrial printer we used costs more than my college tuition (and I went to a private university),” said Alyssa Parkinson, a Solid Concepts rep. ”And the engineers who run our machines are top of the line; they are experts who know what they’re doing and understand 3D Printing better than anyone in this business.”

In other words, there’s a big difference between the gun made by Solid Concepts and the weapons made by Defense Distributed, a Texas-based firm that designed guns intended to be built using 3D printers in your home.

Talking Turkey – Facts About Thanksgiving

Talking Turkey – Facts About Thanksgiving

Thanksgiving

  • The pilgrims did NOT have the first Thanksgiving as we know it.  In fact, Puritans gave thanks by fasting.  The harvest festival with the Pilgrims was to celebrate having enough food not to starve that winter.  The primary foods were corn and eel, though the native Americans also brought in venison, which was the height of the feast.  It was much later that Americans decided this early feast should be called the “first Thanksgiving.”
  • The association between Thanksgiving and the Pilgrims had been suggested as early as 1841 when Alexander Young identified the 1621 harvest celebration as the “first Thanksgiving” in New England, but their importance among the holiday’s symbols did not occur until after 1900. It was then that the familiar illustrations of Pilgrims and Native Americans sitting down to dinner in peace and concord appeared widely in calendar art and on patriotic murals.
  • The pilgrims did not want to go to Plymouth Rock.  They stopped there because they ran out of beer.  Beer was a great way to boil and preserve water and provide nutrition and calories.
  • Squanto, the native that helped them, had lived in England as a slave and returned to America.  He spoke English and knew their ways, so he was a natural go-between.Sarah Josepha Hale, an American magazine editor, persuaded Abraham Lincoln to declare Thanksgiving a national holiday. She is also the author of the popular nursery rhyme “Mary Had a Little Lamb”
  • Sarah Josepha Hale, an American magazine editor, persuaded Abraham Lincoln to declare Thanksgiving a national holiday. She is also the author of the popular nursery rhyme “Mary Had a Little Lamb”
  • Thanksgiving was a National Day of Prayer – hence, the Giving of Thanks to God
  • Abraham Lincoln issued a ‘Thanksgiving Proclamation’ on third October 1863 and officially set aside the last Thursday of November as the national day for Thanksgiving.  It was, in part, a celebration of the Union victories at Gettysburg and Vicksburg that early July.
  • The annual Macy’s Thanksgiving Day Parade tradition began in the 1920’s.
  • In 1939, President Roosevelt proclaimed that Thanksgiving would take place on November 23rd, not November 30th, as a way to spur economic growth and extend the Christmas shopping season.
