New Mexico Mammoth & Other Nifty Science News

What is believed to be the complete skeleton of a mammoth has been discovered near Hobbs.  See what good things happen once we get a Republican in Congress? (Just a way to get in a plug for Steve Pearce)!

Did you know that the Vikings may have brought Native Americans to Europe?

“…The first Native American to arrive in Europe may have been a woman brought to Iceland by the Vikings more than 1,000 years ago, a study by Spanish and Icelandic researchers suggests.

The findings boost widely-accepted theories, based on Icelandic medieval texts and a reputed Viking settlement in Newfoundland in Canada, that the Vikings reached the American continent several centuries before Christopher Columbus traveled to the “New World.”

Spain’s CSIC scientific research institute said genetic analysis of around 80 people from a total of four families in Iceland showed they possess a type of DNA normally only found in Native Americans or East Asians.

“It was thought at first that (the DNA) came from recently established Asian families in Iceland,” CSIC researcher Carles Lalueza-Fox was quoted as saying in a statement by the institute. “But when family genealogy was studied, it was discovered that the four families were descended from ancestors who lived between 1710 and 1740 from the same region of southern Iceland.”

The lineage found, named C1e, is also mitochondrial, which means that the genes were introduced into Iceland by a woman.

“As the island was virtually isolated from the 10th century, the most likely hypothesis is that these genes corresponded to an Amerindian woman who was brought from America by the Vikings around the year 1000,” said Lalueza-Fox….”

In Australia, footage from 2009 of what may be a Thylacine has been released. More from Cryptomundo.  While we are at it, Loren Coleman explores Bigfoot stocking stuffers.  Yea, we had to get Bigfoot in there somewhere, especially since there is not much along the UFO front lately.  But, do not despair, this is one of of the strangest murder mysteries I’ve encountered in ages.

A new vaccine against Alzheimers is being tested on mice.

The Pink Flamingo has been fascinated by the Thylacine quest for years.  Are they extinct or not?

How about a planet from another galaxy?

The lionfish sleeps at night – sorry couldn’t help it.  I have been fascinated with these since The Spy Who Loved Me.

“…, The voracious species is breeding by the thousands, gorging on tropical fish near coral reefs and rapidly spreading from the Bahamas and Florida up to the Carolinas. The reddish-striped fish snarfs up nearly anything it can swallow, from crabs to shrimp to angelfish and other species divers like to see. Its prickly, venom-tipped spines fan out around its body and deter sharks and other predators…. Near scuba spots, divers are increasingly submerging with spears, nets and protective gloves to try to battle the intruder—although divers say they still get stung through gloves. Websites, YouTube videos and Facebook pages describe how to catch and cook it….Stalking the lionfish isn’t easy. The fish, which grow up to about 18 inches, are fast and feisty, divers say. Plus, the tips of their fanned spines give a sting more painful than a bee’s.

“They can get nasty,” says Bob Hickerson, of Vero Beach, Fla., who has killed dozens in the past two years. “I’ve been charged twice, in the face,” he says. He has designed a 14-inch spear that he has used in derbies this year, his team placing first in one and winning $1,600.

Scientists aren’t sure just how the lionfish came to the eastern seaboard. One tale says six lionfish got loose when a beachside aquarium burst during Hurricane Andrew in 1992. The lionfish “almost certainly was released from an aquarium” of some kind, says Mark Hixon, a professor at Oregon State University’s Department of Zoology who studies lionfish….”

There are some cool developments on the T-Rex front.

“…Persons came to this conclusion after comparing the tails of modern-day reptiles, like crocodiles and Komodo dragons, to T.rex’s tail. He found that for all of the animals in his study, the biggest muscles in the tail are attached to upper leg bones. These caudofemoralis muscles provide the power stroke allowing fast forward movement.

But T. rex’s tail was unique.

The tails of both T.rex and modern animals are given their shape and strength by rib bones attached to the vertebrae. Persons found that the ribs in the tail of T. rex are located much higher on the tail. That leaves much more room along the lower end of the tail for the caudofemoralis muscles to bulk-up and expand.

Without rib bones to limit the size of the caudofemoralis muscles, they became a robust power plant enabling T.rex to run.

He now believes that previous estimates of the muscle mass in this dinosaur’s tail were underestimated by up to 45 percent. This explains why earlier researchers thought T. rex was more of a plodding animal that couldn’t run very fast….”
