Using newly refined analysis methods, scientists have discovered that a North Korean nuclear bomb test last fall set off aftershocks over a period of eight months. The shocks, which occurred on a previously unmapped nearby fault, are a window into both the physics of nuclear explosions, and how natural earthquakes can be triggered. The findings are described in two papers just published online in the journal Seismological Research Letters.

The September 3, 2017 underground test was North Korea’s sixth, and by far largest yet, yielding some 250 kilotons, or about 17 times the size of the bomb that destroyed Hiroshima. Many experts believe the device was a hydrogen bomb—if true, a significant advance from cruder atomic devices the regime previously exploded. The explosion itself produced a magnitude 6.3 earthquake. This was followed 8.5 minutes later by a magnitude 4 quake, apparently created when an area above the test site on the country’s Mt. Mantap collapsed into an underground cavity occupied by the bomb.

The test and collapse were picked up by seismometers around the world and widely reported at the time. But later, without fanfare, seismic stations run by China, South Korea and the United States picked up 10 smaller shocks, all apparently scattered within 5 or 10 kilometers around the test site. The first two came on Sept. 23, 2017; the most recent was April 22, 2018. Scientists assumed the bomb had shaken up the earth, and it was taking a while to settle back down. “It’s not likely that there would be so many events in that small area over a small period of time,” said the lead author of one of the studies, Won-Young Kim, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory. “These are probably triggered due to the explosion.”

Just days after North Korea announced it was suspending its testing programme, scientists revealed that the country’s underground nuclear test site had partially collapsed. This assessment was based on data gathered from smaller earthquakes that followed North Korea’s biggest nuclear test in 2017. A new study published in Science has now confirmed the collapse using satellite radar imaging.

The collapse may have played a role in North Korea’s change in policy. If correct, and with the hindsight of this research, we might have speculated that the North Koreans would want to make such an offer of peace. This shows how scientific analysis normally reserved for studying natural earthquakes can be a powerful tool in deciphering political decisions and predicting future policy across the globe.

In fact, another unusual in South Korea in 2017 also has the potential to affect geopolitics, this time by changing energy policy. “Seismic shift” may be a cliche often used by journalists and policymakers to describe changing political landscapes, but these recent earthquakes along the Korean Peninsula remind us there can really be authentic links between and global affairs.

In 2022, if all goes well, NASA will launch Psyche, a space probe intended to visit the asteroid of the same name (16 Psyche is its formal designation). It’s a particularly exciting mission given Psyche’s unique nature and highly unusual composition.

The asteroid belt is composed of three types of asteroid: C-type (carbonaceous, ~75 percent of all asteroids), S-type (silicate-rich, ~17 percent of asteroids) and M-type (metal-rich), which are roughly 10 percent of the total population. The numbers, in this case, don’t add up to 100 percent because we aren’t sure of the exact ratios. 16 Psyche is an M-type asteroid made of iron-nickel. What makes it unusual is that it’s believed to be the now-exposed core of a protoplanet. It’s also estimated to be worth $10,000 quadrillion dollars, if anybody has a towing hitch handy.

16 Psyche isn’t large — its radius is estimated at 112 km, and it isn’t round. Our current best estimate of its composition indicates that it’s 90 percent iron. Its parent body, assuming that it had one, is assumed to have been approximately 500km in diameter, or roughly half the size of Ceres. If Psyche is a core remnant it’s possible that others remain as well, but the asteroid isn’t part of any known family. One theory for its formation is that it was struck a number of times, but never with enough force to shatter it. The remaining fragment represents the iron core of a protoplanet, possibly covered by a thin layer of silicates or remnant components of the original mantle.

A team of researchers at York University has warned that the American bumblebee is facing imminent extinction from Canada, and this could lead to “cascading impacts” throughout the country.

The imminent extinction classification is considered the highest and most at-risk classification before extinction.

About 42 of the more than 850 species of bees in Canada are bumblebees — important pollinators needed to grow crops, including apples, tomatoes, blueberries and legumes, as well as trees, shrubs and wildflowers.

Unusual Trajectory

The new research hasn’t yet been published, but it’s available on the preprint server ArXiv as of Monday. In it, Harvard astronomer Avi Loeb — the same dude who doubled down on the idea that ‘Oumuamua could be an alien spacecraft — suggests that a three-foot-wide interstellar meteor flew over Papa New Guinea’s Manus Island before crashing down.

Because of the meteor’s high speed and particular trajectory past Earth, Loeb and his student Amir Suraj suggest that it couldn’t have been bound in an orbit about the Sun. Rather, they argue, it might have come from somewhere beyond our solar system.

Editor’s Note: The U.S. Transhumanist Party / Transhuman Party features this proposal by our member Hank Pellissier for a new website called Paradise2040, which will focus on the abolition of involuntary suffering and incremental ways of getting there within the next 21 years. This is an endeavor supported by Article IV of the Transhumanist Bill of Rights, Version 3.0. It is also a current within transhumanist thinking that, as Mr. Pellissier points out, could bring additional support to the movement. Different transhumanists will have different views as to what the most important aims of transhumanism should be. As an organization that embraces pluralism and diversity of thought, the U.S. Transhumanist Party / Transhuman Party would encourage any of our members who agree with the direction Mr. Pellissier proposes to collaborate with him on the creation of the Paradise2040 website.

A survey I conducted in 2010 of 818 transhumanists identified “brain enhancement” as the #1 priority, with “maximizing” health and life extension as #2 and #3. The top three “values” of the U.S. Transhumanist Party (the Core Ideals) are #1) Life Extension, #2) “a cultural, societal, and political atmosphere informed and animated by reason, science, and secular values”, and #3) “to reduce and eliminate existential risks.”

Two isolated mountain lion populations in southern California’s Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as within 50 years, according to a study published in the journal Ecological Applications.

The study showed the extinction risk is due to low genetic diversity and mortality that affects the stability of the population. Mountain mortality is often caused by humans, but can also result from changes in the environment, such as wildfire and fluctuations in prey density.

The two mountain lion populations in the human-dominated landscape of southern California are isolated by freeways and development. For the study, lead author John Benson of the University of Nebraska and co-authors at UCLA, the University of California, Davis, the National Park Service, the University of Washington, Northern Arizona University, and the University of Wyoming used population viability modeling to predict the possibilities of extinction from genetic and demographic risk factors.

In 1965, I. J. Good described for the first time the notion of “intelligence explosion”, as it relates to artificial intelligence (AI):

Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion,” and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make, provided that the machine is docile enough to tell us how to keep it under control.

Decades later, the concept of an “intelligence explosion” — leading to the sudden rise of “superintelligence” and the accidental end of the human race — has taken hold in the AI community. Famous business leaders are casting it as a major risk, greater than nuclear war or climate change. Average graduate students in machine learning are endorsing it. In a 2015 email survey targeting AI researchers, 29% of respondents answered that intelligence explosion was “likely” or “highly likely”. A further 21% considered it a serious possibility.
