Fukushima: robot finds massive deposits thought to be melted nuclear fuel

❝ Images captured by an underwater robot on Saturday showed massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan’s destroyed Fukushima nuclear plant.

The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1m on the bottom inside a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima’s Unit 3 reactor, said the plant’s operator, Tokyo Electric Power Co.

❝ On Friday, the robot spotted suspected debris of melted fuel for the first time since the 2011 earthquake and tsunami caused multiple meltdowns and destroyed the plant. The three-day investigation of Unit 3 ended on Saturday.

Locating and analysing the fuel debris and damage in each of the plant’s three wrecked reactors is crucial for decommissioning the plant. The search for melted fuel in the two other reactors has so far been unsuccessful because of damage and extremely high radiation levels…

When you screw-up a nuclear-fueled power plant the sort of damage you produce is generational in scope.

Waymark: First Object Teleported from Earth to Orbit

❝ Last year, a Long March 2D rocket took off from the Jiuquan Satellite Launch Centre in the Gobi Desert carrying a satellite called Micius, named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day.

Micius is a highly sensitive photon receiver that can detect the quantum states of single photons fired from the ground. That’s important because it should allow scientists to test the technological building blocks for various quantum feats such as entanglement, cryptography, and teleportation.

❝ 10th July, the Micius team announced the results of its first experiments. The team created the first satellite-to-ground quantum network, in the process smashing the record for the longest distance over which entanglement has been measured. And they’ve used this quantum network to teleport the first object from the ground to orbit.

❝ Teleportation has become a standard operation in quantum optics labs around the world. The technique relies on the strange phenomenon of entanglement. This occurs when two quantum objects, such as photons, form at the same instant and point in space and so share the same existence. In technical terms, they are described by the same wave function.

The curious thing about entanglement is that this shared existence continues even when the photons are separated by vast distances. So a measurement on one immediately influences the state of the other, regardless of the distance between them.

This is the first time that any object has been teleported from Earth to orbit, and it smashes the record for the longest distance for entanglement.

Happy 150th Birthday

If we borrowed a few politicians from Ottawa, Americans might learn we could do all of these things for the amount of money we currently spend in our federal and state budgets. Starting with Universal Health Care. We could get rid of gerrymandered elections. Can’t guarantee we’d win the Stanley Cup with all American-born players, though. Yet.

Fifty Years Ago, Israel attacked an unarmed US Navy ship killing 34

❝ On June 8, 1967, an Israeli torpedo tore through the side of the unarmed American naval vessel USS Liberty, approximately a dozen miles off the Sinai coast. The ship, whose crew was under command of the National Security Agency, was intercepting communications at the height of the Six-Day War when it came under direct Israeli aerial and naval assault…an attack that would leave 34 Americans dead and 171 wounded.

❝ Last week marked the 50th anniversary of the assault on the USS Liberty, and though it was among the worst attacks in history against a noncombatant U.S. naval vessel, the tragedy remains shrouded in secrecy. The question of if and when Israeli forces became aware they were killing Americans has proved a point of particular contention in the on-again, off-again public debate that has simmered over the last half a century. The Navy Court of Inquiry’s investigation proceedings following the incident were held in closed sessions, and the survivors who had been on board received gag orders forbidding them to ever talk about what they endured that day.

This INTERCEPT article has a couple of documents leaked by Edward Snowden as its core. Excepting these 2 documents, our patriotic spies still keep the entire event under security wraps. So much for transparency in a democracy. Even after a half-century.

A worthwhile read. Learn some real history, folks.

Trump affects America’s tourist business the way we expected

❝ Trump Tower, in midtown Manhattan, has become a modern-day Mount Vernon. Tourists have long visited George Washington’s homestead. Now they venture through Trump Tower’s brass doors to ogle the decor—“it’s so gold,” said a German teenager standing near the lobby’s waterfall on a recent afternoon—or buy souvenirs. The Choi family, visiting from South Korea, wandered the marble expanse with their new “Make America Great” hats (three for $50).

❝ The question for America’s hoteliers and airlines is whether such visitors are just anomalies. A strong dollar is one reason for foreigners to avoid visiting America. Donald Trump may prove another, suggests a growing collection of data. Yet measuring the precise impact of Mr Trump’s presidency on travel is difficult. In addition to the currency effect, many trips currently being taken to America were booked before his election. Marriott, a big hotel company, reported an overall increase, compared with a year earlier, in foreign bookings in America in February.

But Arne Sorenson, Marriott’s boss, has voiced concern about a potential slump in tourism. In February, ForwardKeys, a travel-data firm, reported that in the week after Mr Trump first tried to ban travel from seven Muslim-majority countries, international bookings dropped by 6.5% against the same period in 2016. Hopper, a travel app, found that average daily searches for flights to America have declined in 99 countries since Mr Trump tried to issue his travel ban, compared with the last weeks of Barack Obama’s term. Russia is one of the few places where demand has risen…Tourism Economics, a forecaster, expects 2 million fewer foreign visits to America this year, a 1% drop from 2016. Without Mr Trump it had expected a 3% jump…

❝ The industry has been here before. International tourism in America slumped by around 3% each year from 2000 to 2006. Most analysts blame not only the attacks of 2001 but stricter visa rules and anti-American sentiment abroad. Countries that had the dimmest view of America, according to surveys during that period, tended to see drops in travellers there, says Adam Sacks of Tourism Economics. “We are facing a potential rerun,” he says…

I’m not surprised. Are you? I expect the most insular, if not xenophobic of Trump voters will think the question unimportant. Some people hate realtors. Some people hate travel agents. Usually for not very well thought-out reasons.

Swimming Reindeer

❝ In 1866 French engineer Peccadeau de l’Isle discovered the sculptures of two swimming reindeer on the banks of the River Aveyron. Each had been carved from a mammoth tusk about 13,000 years ago. The carvings had historic as well as artistic value: They showed that humans, mammoths, and reindeer had coexisted in France during the ice age, when the climate of France resembled that of modern Siberia.

❝ Amazingly, it wasn’t until 1904 that anyone thought to try fitting the two pieces together — it was discovered that they were two parts of a single sculpture. Today they form the oldest piece of art in the British Museum.

The British Museum rocks. Even though it’s full of stolen goods.

Carl Bernstein and Bob Woodward celebrate the White House Press Corp

❝ Before comedian Hasan Minhaj got up to poke fun at the assembled White House press corps…Bob Woodward and Carl Bernstein got up to celebrate it.

The legendary Watergate duo gave a speech evoking their investigative reporting of the Nixon administration and calling on the current generation of journalists to practice careful, thorough and relentless reporting on the current White House.
