Samuel Wasser, Africa, Kiva discussed on All Things Considered


Weapons? Kiva gave up. What does that mean? Giving up already all the nuclear weapons already made individual okay now impossible. That was part of the statement. They signed him Singapore, though. Oh, yeah. Via are not reproducing nuclear warfare and nuclear weapons anymore. Vessel for mate. This is our you think the ones you has is our strength because DPRK already developed into nuclear power. This is what they will knows already made all the way it will not give up impulsively. Jay, our guide on a tour of juche tower this month, she is one North Korean one voice and not an official one, but a window into how one North Korean sees her country's nuclear weapons status, and it's changing relations with the US and the world more stories from my reporting trip to Pyongyang in the days ahead. Smugglers are selling tens of thousands of tons of ivory every year that illegal trade threatens the existence of elephants conservationists have developed high-tech strategies to track the source of the ivory NPR's. Christopher Joyce reports on a new effort to trace the smugglers as well. Biologists. Samuel Wasser follows the ivory trade closely. He says too many elephants are dying right now. We're after meeting that they're about forty thousand elephants being killed a year, and there's only four hundred thousand left in Africa. So that's a tenth of the population. A year the cartels that run the ivory trade try to cover their tracks. They falsify shipping documents. For example. They hide ivory in shipping. Containers, they send the average multiple ports before its final destination at the university of Washington. Wasser developed a way to use DNA in tusks to tell what part of Africa the elephants lived in. Now, he's using the technique to home in on the cartels Wasser, analyzed d. Anna from tusks that were seized by customs officials. He noticed that smugglers often separate the two tusks that come from a single elephant and ship them. Separately, presumably to make it harder to track with a came from. But Wasser found a pattern with matching tusks through common port. They were shipped close together in time, and they showed high overlap and the genetically determined origins of the topics. So these three characteristics suggest that the same major trafficking cartel was actually responsible for shipping. Both of the shootings worser says wildlife authorities rarely get enough evidence to identify the big players often. It's they're smaller suppliers who get caught with only as much as they can carry those convictions are well down the smuggling pyramid and don't do much to stem the trade his technique aims higher. When you get a strong connection in the DNA, all of a sudden weak evidence becomes much more confirming Wasser says linking different shipments to a small number of. Sports made about the same time with ivory from elephants in just a few locations in Africa reveals which are the likely cartels doing the smuggling writing in the journal science advances washers team identifies three cartels associated with much the trade. They operate out of Mombasa in Kenya. Entebbe in Uganda and low may in Togo, Christopher Joyce NPR news. You're.
