The Rivers State Governor who said yesterday’s election was the worst political robbery in the nation’s democratic history, stated that the APC Federal Government will not be able to replicate the Ekiti Political Robbery in Rivers State because Rivers people are fully prepared.

Speaking at the Anglican Cathedral Church of Saint Paul, Port Harcourt during the Thanksgiving Service to mark the end of Third Year Anniversary Celebration of his administration, Governor Nyesom Wike said;

“Don’t be worried about what happened in Ekiti State. We are prepared. It will not happen here in Rivers State. I have never experienced that kind of robbery in politics. I told my colleagues, do not give them any chance. Most of them in APC are happy that they will repeat the same thing in Rivers State. We are waiting, come and repeat. Let your spirit was not down, work hard and victory will be ours.”

Governor Nyesom Wike who said the third year anniversary of his administration offered Rivers people the opportunity to witness the superlative performance over the period under the review, added that the State Government has come before God to appreciate him for a hitch-free programme, which spread across two months.

“We made sure that people who have eyes see what we have done for the state. Except for those who are blind, for which there is nothing we can do about it. We will continue to do the best for the people of Rivers State. The people deserve the best. This one year we will not stop doing projects, irrespective of the elections “he said

Concluding his speech at the event, the Rivers State Governor appealed to the people of the state to continue supporting his administration.


Plutonium, cesium and radiation detectors taken after materials left in the back seat

The U.S. government has spent months attempting to find radioactive material stolen out of a van in Texas last year.
In a new report published Monday, the Center for Public Integrity, a self-described nonpartisan news organization focused on corruption, reveals how plutonium, radioactive cesium, and numerous radiation detectors were stolen outside of a San Antonio hotel in March 2017.

The incident began when two employees from the Department of Energy’s Idaho National Laboratory were tasked with traveling to the Lone Star State to obtain radioactive materials from a research lab.

“Their task was to ensure that the radioactive materials did not fall into the wrong hands on the way back to Idaho, where the government maintains a stockpile of nuclear explosive materials for the military and others,” the CPI report states.

The team brought along small samples of plutonium and cesium to both calibrate their radiation detectors and help confirm the right items were retrieved.

After stopping for the evening at a Marriott hotel near Highway 410, the pair noticed the following morning that their vehicle’s windows were smashed and that the sensitive items, left on the back seat, had disappeared.

In the months since state and federal officials have been unable to locate the missing materials.

“No public announcement of the March 21 incident has been made by either the San Antonio police or by the FBI, which the police consulted by telephone,” the CPI says. “When asked, officials declined to say exactly how much plutonium and cesium were missing. But Idaho lab spokeswoman Sarah Neumann said the plutonium, in particular, wasn’t enough to be fashioned into a nuclear bomb.”

Monday’s story is one of many surrounding radioactive substances to go missing from U.S. government control over the past several years.

“Unlike civilian stocks, which are closely monitored by the Nuclear Regulatory Commission and openly regulated—with reports of thefts or disappearances sent to an international agency in Vienna—military stocks tended by the Department of Energy are much less transparent,” the report notes.

The CPI accuses the U.S. government, both currently and in previous administrations, of failing to protect radioactive materials.

The CPI also says documents show that just a month after the theft, “one of the specialists charged with safeguarding the equipment in San Antonio was given a ‘Vision Award’ by her colleagues.”

As much as one pound of plutonium and 45 pounds of high-enriched uranium loaned by the military to different groups including academic researchers are said to be missing.

The Idaho National Laboratory, however, has successfully returned more than “38,000 bits of radioactive material” from hospitals and research centers across the country.

Since the Cold War, the U.S. government, as well as other nuclear powers, have struggled to account for all of their radioactive materials.

Sound waves reveal a huge cache of diamonds inside the Earth (Fairly long research piece)

Sound waves reveal diamond cache deep in Earth’s interior

Study finds 1–2 percent of Earth’s oldest mantle rocks are made from diamond.

From MIT:

There may be more than a quadrillion tons of diamond hidden in the Earth’s interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate the precious minerals are buried more than 100 miles below the surface, far deeper than any drilling expedition has ever reached.

The ultradeep cache may be scattered within cratonic roots — the oldest and most immovable sections of rock that lie beneath the center of most continental tectonic plates. Shaped like inverted mountains, cratons can stretch as deep as 200 miles through the Earth’s crust and into its mantle; geologists refer to their deepest sections as “roots.”

In the new study, scientists estimate that cratonic roots may contain 1 to 2 percent diamond. Considering the total volume of cratonic roots in the Earth, the team figures that about a quadrillion (1016) tons of diamond are scattered within these ancient rocks, 90 to 150 miles below the surface.

“This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says Ulrich Faul, a research scientist in MIT’s Department of Earth, Atmospheric, and Planetary Sciences. “We can’t get at them, but still, there is much more diamond there than we have ever thought before.”

Faul’s co-authors include scientists from the University of California at Santa Barbara, the Institut de Physique du Globe de Paris, the University of California at Berkeley, Ecole Polytechnique, the Carnegie Institution of Washington, Harvard University, the University of Science and Technology of China, the University of Bayreuth, the University of Melbourne, and University College London.

A sound glitch

Faul and his colleagues came to their conclusion after puzzling over an anomaly in seismic data. For the past few decades, agencies such as the United States Geological Survey have kept global records of seismic activity — essentially, sound waves traveling through the Earth that are triggered by earthquakes, tsunamis, explosions, and other ground-shaking sources. Seismic receivers around the world pick up sound waves from such sources, at various speeds and intensities, which seismologists can use to determine where, for example, an earthquake originated.

Scientists can also use this seismic data to construct an image of what the Earth’s interior might look like. Sound waves move at various speeds through the Earth, depending on the temperature, density, and composition of the rocks through which they travel. Scientists have used this relationship between seismic velocity and rock composition to estimate the types of rocks that make up the Earth’s crust and parts of the upper mantle, also known as the lithosphere.

However, in using seismic data to map the Earth’s interior, scientists have been unable to explain a curious anomaly: Sound waves tend to speed up significantly when passing through the roots of ancient cratons. Cratons are known to be colder and less dense than the surrounding mantle, which would in turn yield slightly faster sound waves, but not quite as fast as what has been measured.

“The velocities that are measured are faster than what we think we can reproduce with reasonable assumptions about what is there,” Faul says. “Then we have to say, ‘There is a problem.’ That’s how this project started.”

Diamonds in the deep

The team aimed to identify the composition of cratonic roots that might explain the spikes in seismic speeds. To do this, seismologists on the team first used seismic data from the USGS and other sources to generate a three-dimensional model of the velocities of seismic waves traveling through the Earth’s major cratons.

Next, Faul and others, who in the past have measured sound speeds through many different types of minerals in the laboratory, used this knowledge to assemble virtual rocks, made from various combinations of minerals. Then the team calculated how fast sound waves would travel through each virtual rock, and found only one type of rock that produced the same velocities as what the seismologists measured: one that contains 1 to 2 percent diamond, in addition to peridotite (the predominant rock type of the Earth’s upper mantle) and minor amounts of eclogite (representing subducted oceanic crust). This scenario represents at least 1,000 times more diamond than people had previously expected.

“Diamond in many ways is special,” Faul says. “One of its special properties is, the sound velocity in diamond is more than twice as fast as in the dominant mineral in upper mantle rocks, olivine.”

The researchers found that a rock composition of 1 to 2 percent diamond would be just enough to produce the higher sound velocities that the seismologists measured. This small fraction of diamond would also not change the overall density of a craton, which is naturally less dense than the surrounding mantle.

“They are like pieces of wood, floating on water,” Faul says. “Cratons are a tiny bit less dense than their surroundings, so they don’t get subducted back into the Earth but stay floating on the surface. This is how they preserve the oldest rocks. So we found that you just need 1 to 2 percent diamond for cratons to be stable and not sink.”

In a way, Faul says cratonic roots made partly of diamond makes sense. Diamonds are forged in the high-pressure, high-temperature environment of the deep Earth and only make it close to the surface through volcanic eruptions that occur every few tens of millions of years. These eruptions carve out geologic “pipes” made of a type of rock called kimberlite (named after the town of Kimberley, South Africa, where the first diamonds in this type of rock were found). Diamond, along with magma from deep in the Earth, can spew out through kimberlite pipes, onto the surface of the Earth.

For the most part, kimberlite pipes have been found at the edges of cratonic roots, such as in certain parts of Canada, Siberia, Australia, and South Africa. It would make sense, then, that cratonic roots should contain some diamond in their makeup.

“It’s circumstantial evidence, but we’ve pieced it all together,” Faul says. “We went through all the different possibilities, from every angle, and this is the only one that’s left as a reasonable explanation.”
