• The U.S. State Department’s plans to hold informal talks with North Korea appear to have been derailed by a series of developments, including the recent killing of Kim Jong-nam, the estranged half brother of North Korea’s leader.
The Malaysian government announced that the banned VX nerve agent was used in the killing and said the dose was so high that he died within 20 minutes.
North Korea’s secrecy is sometimes undermined by the government itself. The photo above, of the country’s leader unveiling what he claimed was a new nuclear device in 2016, above, reveals more than he intended.

The beginnings of a revolution in archaeology started on this day in 1940, when a pair of scientists, Martin D. Kamen and Samuel Ruben, confirmed the existence of carbon-14.
A few years later, another scientist, Willard Libby, figured out how to use the isotope to determine the age of fossils and other natural artifacts.
At death, the carbon-14 in living creatures begins to decay. The rate is predictable, so the amount that remains, calculated with a number of other factors, can set relatively precise ages up to about 50,000 years.
Libby won a Nobel Prize in Chemistry for radiocarbon dating, but tragedy struck Ruben. In 1943, he died in a laboratory accident.
For Kamen, a dinner with two Soviet officials in 1944, when he was working on the Manhattan Project, set off rumors that he was a spy.
He lost his job at the University of California, Berkeley, but was eventually able to teach again. One of his last positions was as emeritus professor at U.C. San Diego, where he had helped found the chemistry department decades earlier.
