Mammoth calf, preserved

The surprisingly well-preserved body of a woolly mammoth calf is on loan from Siberia to Victoria’s Royal British Columbia Museum.  The infant mammoth is thought to have been one month old at the time that she drowned and froze to death 40,000 years ago.  Lyuba is named for the wife of the Siberian shepherd who discovered the mammoth.  I’m sure the wife was thrilled about that.  From CBC News:

New Royal BC Museum exhibit features Lyuba, a 40,000-year-old baby mammoth

Exhibit also features a dire wolf, made famous by Game of Thrones

Dire wolves, mastodons and short-faced bears, oh my.

Those are just some of the creatures featured in a new exhibit at Victoria’s Royal BC Museum called Mammoths: Giants of the Ice Age.

The exhibit includes a 40,000-year-old baby woolly mammoth as its centrepiece, which the museum calls the best-preserved specimen in existence.

The mammoth, on loan from the Shemanovskiy Yamal-Nenets District Museum and Exhibition Complex in Siberia, has been travelling the world since 2010.

The mammoth is named Lyuba, after the wife of the Siberian herder who discovered it, according to Evgeniya Khzyainov, deputy director and curator for the Shemonovskiy Museum.

Khzyainov told All Points West’s Sterling Eyford that the mammoth was about one or two months old when it died by drowning.

“When she died she wasn’t damaged by other animals, she was frozen, and when she froze it was [lucky] she wasn’t damaged again by animals,” said Khzyainov…

Georgians can see Vietnam Memorial locally

Standard

“The Wall That Heals” is open for visitation at Veterans Memorial Park at 651 Hyden Tyler Road in Chatsworth, Georgia from now until the end of the week.  The portable version of the Vietnam Memorial in Washington D.C. gives smaller communities a chance to see the monument.  On Sunday, May 15, there will be a closing ceremony before the mobile war memorial is moved to its next location.  Chattanooga’s WRCB has the story:

Vietnam Veterans Memorial visit North Georgia

Harvey Roach served in Vietnam from 1967 through 1969.

He remembers difficult days when he returned home to Georgia.

“We were called baby killers, we were spit on, you name it,” said Roach.

He also remembers the lives lost- brothers and sisters he plans to honor by visiting the Vietnam Memorial Wall in Chatsworth.

“When they set the wall up, it’s going to get emotional,” said Roach.

Tim Tetz with the Vietnam Veterans Memorial Fund says the traveling wall allows everyone who was touched by Vietnam to remember what happened 50 years ago.

“This gives an opportunity for someone who lost a love one who served there, to pay their respects to their name and remember their sacrifice,” said Tetz.

The wall constructed of powder-coated aluminum will make 35 stops through December.

Tetz says for some, the wall offers healing.

“This is called: “The wall that heals.” When our founder came up with the idea to build a national memorial for our Vietnam veterans he realized there would be some healing there, but didn’t realize how much,” said Tetz.

Tetz has been carrying the stories of people who served in Vietnam since 1999, including the four people from Murray County who died in the war.

He says the mobile wall gives those who haven’t had the chance to visit the Vietnam Memorial in Washington D.C., the chance to honor the 58,307 men and women who died…

The wall will return to Georgia Nov. 16-20 in Woodstock.

“Mammoth species interbred, perhaps extensively”

Standard

A new study of mammoth DNA suggests that mammoths mated outside of their species. Mammoth tissue specimens reveal that woolly mammoths of cold regions in North America bred with temperate climate Columbian mammoths. The news is surprising to me given the social cohesion of mammoth herds. I would have thought that herds would have resisted advances by bull mammoths with distinctive phenomes.

Phys.org sums up the study:

…By using differences in the size and shape of their fossilized teeth, a number of North American mammoth species have been identified. But, some scientists are not confident this method of species categorization tells the whole story.

“Species boundaries can be very blurry. We might find differences in features of the teeth or skeleton that closely correspond to what we think are real species boundaries. But other features may not correspond to those boundaries, suggesting that what we formerly regarded as separate species are in fact not at all,” explains Hendrik Poinar, a Professor at McMaster University in Canada, who co-led the new study with his former graduate student Jake Enk and collaborator Ross MacPhee, a Professor at the American Museum of Natural History.

Professor Poinar and his co-authors used cutting-edge methods to distinguish species of North American mammoths. Tiny samples of fossilized mammoth bone, teeth and faeces, were generously donated by a number of museums across America and Canada. DNA was extracted from these samples in a specialized laboratory of the Ancient DNA centre at the McMaster University, and used to create a family tree of their evolution. The results proved to be very interesting.

North American mammoths such as the Columbian and Woolly Mammoths were historically thought to originate from two separate primitive species. However, this latest DNA analysis agrees with a more recent idea that all North American mammoths originated from a single primitive species, the Steppe Mammoth.

“Individuals of the Woolly and Columbian mammoths look like they represent different species in terms of their molar teeth, but their genetics say that they were not completely separate in the evolutionary sense and could successfully interbreed,” says Professor MacPhee.

Professor Poinar continues, “Mammoths were much better at adapting to new habitats than we first thought—we suspect that subgroups of mammoths evolved to deal with local conditions, but maintained genetic continuity by encountering and potentially interbreeding with each other where their two different habitats met, such as at the edge of glaciers and ice sheets.”

So, while mammoths clearly evolved differences in their physical appearance to deal with different environments, it did not prohibit them from cross-breeding and producing healthy offspring…

Mammoth skull unearthed in Oklahoma

Standard

A construction worker in Oklahoma recently found part of a skull and tusk of a Columbian mammoth.  Mammoth remains are found a couple of times per year in that part of the country.  They must have been plentiful back then.  From the Spanish wire service EFE:

Archaeologists have found a mammoth skull and two tusk fragments in a sand pit in northeastern Oklahoma, media reports said.

The Oklahoma Archeological Survey, or OAS, identified the animal as a Columbian mammoth, one of the last species of that giant mammal to inhabit both North America and Central America, ranging between what are today the United States and Costa Rica.

“The exact age of the deposit has not yet been determined,” the OAS said in a post on its Facebook page.

Archaeologists went to the scene after receiving images of part of a skull being dug out of the sand near Alva, located 240 kilometers (150 miles) northeast of Oklahoma City.

Before becoming extinct more than 11,000 years ago, mammoths were common during the Pleistocene epoch in this central area of the United States, where two or three mammoth remains are found every year, archaeologists say.

The Columbian mammoth could reach a shoulder height of 4 meters (13 feet), weigh 8 to 10 tons and have a life span of 80 years…

General Assembly creates fintech study group

Atlanta's Transaction Alley

Map of Atlanta-area fintech companies

On the final day of the legislative session last month, the Georgia House of Representatives approved the creation of a new financial technology committee.  The study committee will examine possible incentives such as tax breaks for financial technology companies and payment processors in Georgia.

Lawmakers noted in the text of Senate Resolution 883 that over 70 percent of all financial transactions processed in the United States are actually processed by companies headquartered in Georgia.  Georgia’s “Transaction Alley” is responsible for 40,000 jobs plus another 40,000 related support jobs.  Sen. Brandon Beach (R-Alpharetta) and Elena Parent (D-Atlanta)—the senator for the district I live in—were among the cosponsors.

Study committees like this tend to schedule a few hearings where they talk to industry experts and a couple of state government officials.  They come up with reports that often become the basis of legislation in the upcoming year.  I would predict that this study committee may come up with some tax incentives for financial technology companies to locate or remain in Georgia.  They could design these along the lines of Georgia’s successful film tax credit.  The committee may also encourage venture capital investments into fintech startups.

Lab seeks artificial womb for mammoths

Standard

asian elephant calf in the womb

It would be too controversial to implant a woolly mammoth embryo in an endangered Asian elephant surrogate.  Therefore, an artificial mammoth womb must be created.  So says Dr. George Church, the Harvard biologist on a mission to resurrect the mammoths.

Scientific American reports that “editing, birthing and then raising mammoth-like elephants is a huge undertaking. Church says that it would be unethical to implant gene-edited embryos into endangered elephants as part of an experiment. So his lab is looking into ways to build an artificial womb; so far, no such device has ever been shown to work.”

The creation of a mammoth-like uterus would be quite the scientific accomplishment since scientists have yet to master that with existing animals…

Georgia honors 19 Vietnam combat Marines

Viet Marines

This is part of a broader, overdue program to thank over 200,000 of Georgia’s Vietnam veterans for their service.  From the Columbus Ledger-Enquirer:

Georgia recognizes Vietnam vets who served in Marine Corps

  • 19 Marines from the Chattahoochee Valley were presented a State Certificate of Honor and lapel pin for service in Vietnam
  • The recognition is part of the state’s program to recognize 234,000 Georgia veterans who served in armed forces during Vietnam
  • Program started a year ago as part of the 50th anniversary of the war

Osteoporosis, not man, killed the mammoths?

Standard

A mammoth graveyard in southern Russia shows no sign of significant human activity according to a new documentary.  The documentary also reveals that 40 percent of woolly mammoth bones indicate osteoporosis.  While this doesn’t let early man off the hook in terms of hunting mammoth populations elsewhere, it shows it wasn’t a factor in this case.  The other interesting aspect of this news article from The Siberian Times what may have drawn mammoths to the site:  salt.

Paleothithic man ‘not the main cause of deaths at vast mammoth graveyard’

By Olga Gertcyk

22 February 2016

Experts say no sign of any human settlements close to ‘largest necropolis in Asia for the extinct beasts’.

While a few human implements have been found at Mammoth village, there is a striking lack of man’s presence at the probably most recent known large cemetery for the ancient giants, according to a new documentary from Tomsk State University.

The film appears to clear Paleothithic man of having much to do with the demise of the species here, although the creatures were clearly filleted for meat and hide, and their tusks were purloined some 10,000 to 14,000  years ago.

All the implements were not made of local stone, and in fact came from hundreds of kilometres away from the site in Novosibrisk region that may hold the key to why the the mammoths finally died out. They were less weapons than butchering tools, it is believed.

So man did not live close to a place where the ailing mammoths came to die, but visited to raid the enfeebled animals after they tramped here from huge distances.

Paleontologists want to massively extend excavations at the site, known as Volchya Griva at Mamontovoye – or Mammoth – village after a dig in 2015 resulted in the discovery of more than 600 bones and teeth.

Eminent Soviet archeologist Aleksei Okladnikov in 1969 noticed how at the site ‘bones were lying at the same level horizontally – and had no marks of any sort of catastrophic influence’.

The short documentary cites a number of leading experts noting the lack of human presence at the site. Academician Dr Vyacheslav Molodin, an archeologist, one of the first researchers at Volchya Griva, said: ‘Of course when I went there I was hoping to find some human dwelling. But, unfortunately, we didn’t find it.’

Dr Vasily Zenin, of the Institute of Archeology and Ethnography in Novosibirsk, said: ‘It was expected to find a Paleolitic dwelling there, perhaps, some religious constructions.’ However, ‘when we started digging, it became obvious that presence of humans was very limited. There were no conditions for a permanent settlement in Volchya Griva or around it.’

Equally, the half dozen mammoth remains found during research in summer 2015 all appeared to have died relatively young. The creature had a lifespan of 60 to 80 years, but of the six animals found here included two that died between one and 12 years old, one under a year old and two between 12 and 25 years. Two were older than 25.

Intriguingly, some 40% of the woolly mammoth bones found here show signs of bone diseases.

The Siberian Times has examined previously the theory of Dr Sergey Leshchinsky, head of the Laboratory of continental ecosystems of Mesozoic and Cenozoic of  Tomsk State University, that osteoporosis was a key factor in the demise of the animals, and that the reason they came to this site was because it was a ‘salt lick’ offering them the chance to rectify mineral deficiencies…

Elephant sanctuary in Brazil reviews toxic plant risks

Standard

The Global Sanctuary for Elephants is developing a new refuge for elephants in Brazil, involving everything from installing steel pipe fences to assessing whether the local flora pose any health risks to elephants.

GSE reports that five countries in South America have banned elephant performances in circuses and shows.  This has resulted in elephants literally being sent to pasture, sometimes with inadequate care.  The goal of GSE is to complete a 2,800 acre natural refuge for a small herd of elephants.  Elephant Sanctuary Brazil is said to be the first and only elephant sanctuary in South America.

On their blog, GSE recently reported on an interesting consideration, which is that toxic plants could pose a risk to elephants who grew up without being exposed to that vegetation.  But GSE looked into it and found that elephants seem to have an instinctive understanding of which plants are dangerous even though their mothers never taught them to avoid them.  Check out what they learned from an elephant sanctuary in Tennessee:

http://www.globalelephants.org/elephants-and-toxic-plants/

The sanctuary will offer the opportunity to researchers to learn more about this behavior.

Tourist climbs 20 feet to elude tiger for 2 hours

Tour guide Krishna Shah was injured while attempting to distract a Bengal tiger in Bardia National Park in Nepal.  His client, a tourist from the Netherlands, climbed a tree for safety.  The tour guide returned a couple hours later with backup to save Gerard Van Laar.  Kudos to Mr. Shah for returning to the site despite his own injuries to save the Dutchman!

The Metro has the story:

A Dutch tourist managed to escape from a prowling Bengal tiger by hiding up a tree for more than two hours.

Gerard Van Laar was walking in a Nepalese national park with his guide when they suddenly heard a growling roar and saw the animal ‘heading towards us at full speed’.

His guide Krishna selflessly saved the tourist’s life by running into the jungle to draw the tiger’s attention, and telling Gerard to climb the tree.

Tigers are capable of climbing sturdy trees but it is relatively rare for them to do so.

Freelance engineer Gerard, 33, said he was lucky to be alive after the attack on Saturday.

He had been trekking in Bardia National Park, around 250 miles southwest of the capital, Kathmandu.

‘I would have been dead if it had not been for Krishna,’ he told The Associated Press.

Krisha was attacked and slightly injured after he saved the other man, but escaped to raise the alarm.

As Gerard waited in the tree, the tiger returned and started circling while the man in the branches tried to stay as still and quiet as possible around 20 feet above the ground.

Around two hours later the guide came back with help, shouting and using sticks to drive the tiger away…
