Xen­on, an ele­ment that is found in trace amounts after nuc­le­ar weapons tests and oth­er nuc­le­ar activ­it­ies, was de­tec­ted by a South Korean nuc­le­ar reg­u­lat­ory ex­pert or­gan­iz­a­tion in June, Yon­hap News Agency re­por­ted.

The Korea In­sti­tute for Nuc­le­ar Safety de­tec­ted the pres­ence of the gaseous ele­ment three times in June, sources told the wire ser­vice. 

A nuc­le­ar weapons test by North Korea was con­duc­ted in Feb­ru­ary, but no signs of nuc­le­ar activ­ity em­an­ated from the North around the time the gas was dis­covered, ac­cord­ing to Yon­hap. Xen­on iso­topes break down re­l­at­ively quickly, so the de­tec­ted gas may not be from any re­cent nuc­le­ar activ­ity from the North, ac­cord­ing to a source for the Korean wire ser­vice. The rare iso­topes found over South Korea could have ori­gin­ated in Ja­pan, from ra­di­ation leaks stem­ming from the dam­aged Fukushi­ma Daii­chi nuc­le­ar fa­cil­ity, the Wall Street Journ­al re­por­ted.

“Rel­ev­ant agen­cies are con­duct­ing an ana­lys­is, and that’s what we know of,” a South Korean De­fense Min­istry spokes­man told the Journ­al

A North Korean an­nounce­ment in April that a re­act­or and urani­um en­rich­ment plant at the Yongby­on com­plex would be ac­tiv­ated has not been de­tec­ted by the South, ac­cord­ing to Yon­hap’s sources, but the fa­cil­ity could have be­gun the start-up pro­cess in May.

Mean­while, South Korea’s spe­cial rep­res­ent­at­ive for peace and se­cur­ity af­fairs left the Asi­an na­tion for a three-day trip to Rus­sia, where he will meet with Rus­sia’s top ne­go­ti­at­or for Py­ongy­ang’s de­nuc­lear­iz­a­tion, Yon­hap also re­por­ted.

“I plan to share de­tailed opin­ions on how to as­sess North Korea’s nuc­le­ar pro­grams and threats and dis­cuss how to push ahead with ef­forts to de­nuc­lear­ize the North dur­ing this vis­it,” the South Korean en­voy told Yon­hap.

A sev­enth round of meet­ings between the North and the South over the fu­ture of the shuttered Kaesong In­dus­tri­al Com­plex will be­gin on Wed­nes­day. Ne­go­ti­ations will hinge on mak­ing pro­gress on con­di­tions that South Korea as­serts are ne­ces­sary to pre­vent work stop­pages in the fu­ture, Yon­hap re­por­ted sep­ar­ately on Tues­day.

North Korea is also at­tempt­ing to im­prove dip­lo­mat­ic ties with vari­ous coun­tries in Africa, in a move that ob­serv­ers say is an at­tempt to es­cape the glob­al isol­a­tion that the Asi­an na­tion has faced dur­ing its pur­suit of nuc­le­ar weapons, ac­cord­ing to an­oth­er Yon­hap re­port.

Is McMullin Building the GOP in Exile?

Evan McMullin, the independent conservative candidate who may win his home state of Utah, is quietly planning to turn his candidacy into a broader movement for principled conservatism. He tells BuzzFeed he's "skeptical" that the Republican party can reform itself "within a generation" and that the party's internal "disease" can't be cured via "the existing infrastructure.” The ex-CIA employee and Capitol Hill staffer says, “I have seen and worked with a lot of very courageous people in my time [but] I have seen a remarkable display of cowardice over the last couple of months in our leaders.” McMullin's team has assembled organizations in the 11 states where he's on the ballot, and adviser Rick Wilson says "there’s actually a very vibrant market for our message in the urban northeast and in parts of the south."

Too Many Potential Enrollees Paying Obamacare Penalties Instead
4 hours ago

One of the main reasons for the recent Obamacare premium hikes is that many potential enrollees have simply decided to pay the tax penalty for remaining uninsured, rather than pay for insurance. More than 8 million people paid the penalty in 2014, and preliminary numbers for 2015 suggest that the number approaches 6 million. "For the young and healthy who are badly needed to make the exchanges work, it is sometimes cheaper to pay the Internal Revenue Service than an insurance company charging large premiums, with huge deductibles."

Cruz: Eight Justices Could Be an Ongoing Situation

Sen. Ted Cruz (R-TX) said that "there was “precedent” for a Supreme Court with fewer than nine justices—appearing to suggest that the blockade on nominee Merrick Garland could last past the election." Speaking to reporters in Colorado, Cruz said: "I would note, just recently, that Justice Breyer observed that the vacancy is not impacting the ability of the court to do its job. That’s a debate that we are going to have.”
