July 1, 2013 ? University of Utah researchers developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon-14 deposited in tusks and teeth by open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally.
"This could be used in specific cases of ivory seizures to determine when the ivory was obtained and thus whether it is legal," says geochemist Thure Cerling, senior author of a study about the new method. It was published online the week of July 1 in the journal Proceedings of the National Academy of Sciences.
"The dating method is affordable and accessible to government and law enforcement agencies," costing about $500 per sample, says the study's first author, geochemist Kevin Uno, who did the research for his University of Utah Ph.D. thesis.
"It has immediate applications to fighting the illegal sale and trade of ivory that has led to the highest rate of poaching seen in decades," says Uno, now a postdoctoral researcher at Columbia University's Lamont-Doherty Earth Observatory.
Not only can the method help wildlife forensics to combat poaching, but "we've shown that you can use the signature in animal tissues left over from nuclear weapons testing in the atmosphere to study modern ecology and help us learn about fossil animals and how they lived," says Cerling, a distinguished professor of geology and geophysics, and biology at the University of Utah.
The method uses the "bomb curve," which is a graph -- shaped roughly like an inverted "V" -- showing changes in carbon-14 levels in the atmosphere -- and thus absorbed by plants and animals in the food chain. The carbon-14 was formed in the atmosphere by U.S. and Soviet atmospheric nuclear weapons tests in Nevada and Siberia from 1952 through 1962. Those levels peaked in the 1960s and have declined ever since but still are absorbed by and measurable in plant and animal tissues.
The study was funded by the National Science Foundation, the National Geographic Society and the University of Utah. Cerling and Uno conducted it with geologist Jay Quade, a former Utah doctoral student now at the University of Arizona; Daniel C. Fisher, University of Michigan, Ann Arbor; George Wittemyer, Colorado State University; Iain Douglas-Hamilton, founder of Save the Elephants; and Samuel Andanje, Patrick Omondi and Moses Litoroh, all of the Kenya Wildlife Service.
Ivory Trade Drives Elephant Slaughter
International agreements banned most trade of raw ivory from Asian elephants after 1975 and African elephants after 1989. In the United States, raw and worked African ivory (jewelry, figurines, gun and knife handles) is legal if it was imported before 1989 or, if worked ivory is imported after, it must be at least 100 years old.
Yet tons of illegal ivory still are sold because dealers claim the ivory was taken before the ban and there has been no test to prove them wrong -- until now.
"With an accurate age of the ivory, we can verify if the trade is legal or not" when the age is combined with existing DNA analysis to determine if an elephant is from Africa or Asia, says Uno, who earned his University of Utah Ph.D. last year. "Currently 30,000 elephants a year are slaughtered for their tusks, so there is a desperate need to enforce the international trade ban and reduce demand."
Only 423,000 African elephants are left. Conservation groups say 70 percent of smuggled ivory goes to China. The United States is the next biggest illegal market. Rising ivory prices have drawn organized crime and spurred militias in Darfur, Uganda, Sudan and Somalia to kill elephants and sell tusks so they can buy guns.
How the Study Was Performed
Neutrons from the nuclear tests bombarded nitrogen -- the atmosphere's most common gas -- to turn some of it into carbon-14. Cosmic rays do that naturally at a low level, but open-air nuclear tests in the 1950s and 1960s sharply increased atmospheric, plant and animal carbon-14 levels, followed by a steady decline ever since.
The method in the study is a bit like telling a tree's age by its rings, but instead of counting rings, Cerling, Uno and colleagues measured carbon-14 levels at various points along the lengths of elephants' and hippos' tusks and teeth.
The conventional way of measuring carbon-14 is to wait for and count when the isotope decays radioactively. In the study, the researchers used accelerator mass spectrometry, or AMS, which requires 1,000 times less material for analysis -- a big advantage when sampling fossils or small pieces of worked ivory, Cerling says.
In AMS, the material being analyzed is bombarded with cesium atoms, which sputters off carbon atoms so the ratio of carbon-14 to carbon-12 can be measured.
The researchers tested the accuracy of carbon-14 dating in 29 animal and plant tissues killed and collected on known dates from 1905 to 2008. The samples included elephant tusks and molars, hippo tusks and canine teeth, oryx horn, hair from monkeys and elephant tails, and some grasses collected in Kenya in 1962.
Samples came from museums in Africa and elsewhere, and from Amina, an elephant that died naturally in Kenya in 2006, and from Misha, an African elephant euthanized in 2008 due to declining health at Utah's Hogle Zoo in Salt Lake City.
The analysis revealed that various tissues that formed at the same time have the same carbon-14 levels, and that grasses and the animals eating them had the same levels. By determining carbon-14 in these samples of known dates, the researchers now can measure carbon-14 levels in other ivory to determine its age, within about a year.
The four oldest samples -- from animals died between 1905 and 1953 -- had minimal carbon-14 because they died before atmospheric nuclear weapons tests. So the test can identify pre-1955 ivory by its low, pre-nuclear-test levels of carbon-14.
Cerling says the method can determine the year of death for any animal killed after 1955, identifying the time of the most recent tissue formation -- at the base of a tusk or tooth, for example. The method is less precise for animals killed more recently; it can tell if an animal died between 2010 and 2013, but not more precisely.
It takes about 5,700 years for half of carbon-14 to decay radioactively. But the amount in Earth's atmosphere after the 1950s and 1960s bomb tests faded much more quickly because oceans and trees absorb carbon dioxide -- including carbon-14 -- from the atmosphere. So the method won't work for tusks or other tissues that grow after about 15 years from now, when atmospheric carbon-14 returns to pre-bomb levels.
Understanding Ancient and Modern Ecosystems
While the method's use against poaching is important, "the scientific part is the importance of understanding time in the formation of animal tissues and how diet and physiology is recorded in those tissues over time" as they grow, Cerling says.
Cerling says that will improve understanding of what prehistoric and modern animals ate over time, especially when combined with existing isotope analysis of ratios of carbon-13 to carbon-12 in teeth -- data that reveal whether animals ate diets based on tree and shrub leaves and fruits, or upon grasses and grazing animals.
So as part of the new study, the scientists also analyzed another 41 samples to determine the growth rates for tusks and teeth from elephants and hippos, and elephant tail hair, Cerling says.
Extrapolating the growth rates of tusks, teeth and hair to fossil or modern elephants and other animals "will help us improve the chronology of the diet history of an individual fossil or modern animal," Cerling says.

Protesters attacked and stormed the headquarters of the Muslim Brotherhood in Cairo, calling for Egypt's president Mohammed Morsi to step down. NBC's Ayman Mohyeldin reports.
By F. Brinley Bruton, NBC News
The headquarters of the President Mohammed Morsi's Muslim Brotherhood were looted and ransacked early on Monday in the wake of?a day of violence that left at least 16 people dead and more than 700 injured in protests throughout the country.
The bloodiest incident of the weekend's huge and mostly peaceful protests against?President Mohammed Morsi and the Muslim Brotherhood?began after dark and continued for hours, with guards inside the suburban Cairo building firing on youths hurling fire bombs and rocks. Reuters cited medical and security sources as saying that eight people were killed but the figure could not be independently confirmed by NBC News.

Egyptian men carry items looted from the burnt headquarters of the Muslim Brotherhood in Cairo on Monday.
Protesters breached ?the Cairo compound's defenses and stormed the building. Crowds later carried off furniture, files, rugs, air conditioning units and portraits of Morsi, according to an Associated Press journalist. One protester emerged with a pistol and handed it over to a policeman outside. ?
Footage on local television showed broken windows, blackened walls and smoke coming out of the building. A fire was still raging on one floor hours after the building was invaded. One protester tore down the Muslim Brotherhood sign from the building's front wall, while another hoisted Egypt's red, black and white flag out an upper-story window and waved it in the air in triumph.
The images were reminiscent of the destruction of the state security headquarters when Hosni Mubarak was toppled in 2011.
A spokesman for the Brotherhood said it would be demanding answers from security officials who failed to protect it. ?He said two of those inside were injured ?before a security detail from the movement was able to evacuate all those inside the compound in mid-morning.
Organizers behind Sunday's protests -- who managed to get 22 million signatures calling on Morsi to step down -- ?said they would give him until Tuesday at 5 p.m. (11 a.m. ET) to meet their demands otherwise they would call for nationwide strikes.?
Egypt's Tahrir Square continues to be the center of violent protests more than two years after the Arab Spring ousted long-time ruler Hosni Mubarak. Now, supporters and opponents of President Mohammed Morsi are clashing, with efforts afoot to remove the democratically elected leader, NBC's Ayman Mohyeldin reports.
Protesters also demanded?early elections, but late on Sunday night word from the presidential palace was that Morsi had no intentions of calling them.?
Some anti-Morsi protesters spent Sunday night in dozens of tents pitched in the capital's central Tahrir Square and in front of the president's Ittihadiya Palace. They have vowed to stay there until Morsi resigns. Morsi supporters, meanwhile, went on with their sit-in in front of a major mosque in Cairo.?
Sunday's protests were the largest seen in Egypt in the 2? years of turmoil since the ouster of autocratic Mubarak in February 2011.?
NBC News' Ayman Mohyeldin and Charlene Gubash, Reuters and The Associated Press contributed to this report.

US President Barack Obama on Monday called on all parties in Egypt to show restraint in mass protests against President Mohamed Morsi, and specifically warned against attacks on women.
?Everybody has to show restraint,? Obama said at a press conference in Tanzania, adding that ?for those who are participating in these protests or marches, assaulting women does not qualify as peaceful protests?.
Egypt?s opposition earlier on Monday gave Morsi a day to quit or face civil disobedience after deadly protests demanded the country?s first democratically elected president step down after just a year in office.
Obama did not take a position on whether it was time for Morsi to go, but called on his government to reach out to the opposition and work through a legitimate process, and to observe the rule of law.
?What is clear right now is that although Mr Morsi was elected democratically, there is more work to be done to create the conditions in which everybody feels their voices are heard,? Obama said.

The Wanted and Backstreet Boys perform at London's Gay Pride
June 30, 2013, 12:29 PM EST
WENN
The Wanted and the Backstreet Boys celebrated with their gay fans on Saturday by performing a joint gig at London's premier gay nightclub.
The two groups took over the G-A-Y night at U.K. hotspot Heaven, hours after an estimated 15,000 revellers took to the streets in the British capital to march in the 42nd annual Gay Pride parade.
Before their sets, the groups posed for photos together backstage and Backstreet Boy Nick Carter tweeted, "Getting ready to play club G.A.Y. In London. We are so excited to party with our gays. gay pride."
The festivities in London came just weeks after British government officials approved same-sex marriage legislation, paving the way for ceremonies to begin next spring.
Pop superstars Lady Gaga and Cher also performed in Gay Pride events held in New York this week.

Everyone has a different story. I found myself holding my breath listening to them talk. The story twists like a thriller.
Stories We Tell is not just very moving; it is an exploration of truth and fiction that will stay with you long after repeated viewings.
Part of the movie's pleasure is how comfortable the "storytellers" are with their director; you get a sense of a complicated but tight-knit family, going along with Sarah's project because they love her.
Never sentimental, never cold and never completely sure of anything, Polley comes across as a woman caught in wonder.
After you see it, you'll be practically exploding with questions - and with awe.
Polley approaches every character with compassion, intent upon blessing them, and serving the audience with useful questions about how we seek the truth.
Polley is working in the tradition of Orson Welles, but her trickery can be exasperating; it also neutralises many of the emotional revelations.
With Away From Her and Take This Waltz, actress-turned-filmmaker Polley has proved herself as an unusually gifted director, but this inventive, moving documentary reveals even more artistic ambition.
What saves it is our realisation that it isn't just a documentary.
A bittersweet and compelling autobiographical family portrait.
Kane-like in its mirrored complexity, flashing in its mischievous irony, the story is a shiny maze which Polley enters knowing exactly where and what her Minotaur is - the secret of her paternal parentage - while spinning for us a thread to follow.
Polley ... smilingly tells us that a story like hers can never truly be tied down, even as she screws every last piece into place.
Polley's cine-tribute is a gripping and absorbing meditation on the unknowability of other lives.
The films greatest achievement is in how deeply mesmerising one woman's story can be, regardless of whether she's famous or not.
Honestly, it's one of the best things you'll see this year.
Polley's fearless personal journey is a huge achievement, a genuine revelation - but the less detail you know beforehand, the better. Go in cold, come out warmed.
Sarah Polley is often referred to in Canada as a 'national treasure'. She's far more than that. She's a treasure to the world - period. And so, finally, is her film.
An absorbing exercise not only in documentary excavation but in narrative construction.
Sarah Polley's exploration of her tangled family history is a complex and thoroughly fascinating inquiry into the nature of truth and memory -- and, inevitably, into Polley herself.
This is simply a gorgeously realised and warmly compiled family album, which lingers with us not because its subjects are so unusual and alien, but because they feel so close to home. What a success.
Sarah Polley's personal "documentary" suffers from one additional emotional beat too many. Otherwise, it's mesmerizing.
Polley interviews her family and acquaintances with remarkable candor and intimacy, perhaps as a method of catharsis, but it never feels like a vanity project or a simple airing of dirty laundry.
The great conceit of Polley's theories of perspective and truth is that she, as director, ultimately controlled everyone's memories because she arranged them on film.
