Reuters Africa reports that authorities are not out of the woods yet, because they expect nuclear facilities along the Mississippi River, including the Grand Gulf Plant, to be hit by flooding through the month of May. See a section of that report below the jump.Workers at the Grand Gulf Nuclear Plant in Port Gibson, Miss., last Thursday [28 April] released a large amount of radioactive tritium directly into the Mississippi River, according to the US Nuclear Regulatory Commission (NRC), and experts are currently trying to sort out the situation. An investigation is currently underway to determine why the tritium was even present in standing water found in an abandoned unit of the plant, as well as how much of this dangerous nuclear byproduct ended up getting dumped into the river. Many also want to know why workers released the toxic tritium before conducting proper tests.
The Mississippi Natchez Democrat reports that crews first discovered the radioactive water in the plant's Unit 2 turbine building after heavy rains began hitting the area last week. Unit 2 was a partially-constructed, abandoned structure that should not have contained any radioactive materials, let alone tritium, which is commonly used to manufacture nuclear weapons and test atomic bombs ... .
According to reports, alarms began to go off as workers were releasing the radioactive storm water into the river, which engaged the stop flow on the release pump. Neither NRC nor plant officials know how much tritium was released into the river during this release.
"Although concentrations of tritium exceeded EPA drinking water limits, the release should not represent a hazard to public health because of its dilution in the river," insisted Lara Uselding, public affairs officer at NRC Region IV, to reporters.
Below the jump, interviews with the last surviving World War I soldiers, who have all died in the past decade.Claude Stanley Choules, the last known combat veteran of the first world war, died on Thursday at a nursing home in Perth, Western Australia his family have said. He was 110.
"We all loved him," his 84-year-old daughter Daphne Edinger said. "It's going to be sad to think of him not being here any longer, but that's the way things go."
Beloved for his wry sense of humour and humble nature, the British-born Choules nicknamed "Chuckles" by his comrades in the Australian navy never liked to fuss over his achievements, which included a 41-year military career and the publication of his first book at the age of 108.
He usually told the curious that the secret to a long life was simply to "keep breathing." Sometimes, he chalked up his longevity to cod liver oil. But his children say in his heart, he believed it was the love of his family that kept him going for so many years.
"His family was the most important thing in his life," his other daughter, Anne Pow, said in a March 2010 interview. "It was a good way to grow up, you know. Very reassuring."
Choules was born on 3 March, 1901, in Pershore, Worcestershire, one of seven children. As a child, he was told his mother had died – a lie meant to cover a more painful truth. She left when he was five to pursue an acting career. The abandonment affected him profoundly, Pow said, and he grew up determined to create a happy home for his own children.
In his autobiography, The Last of the Last, he remembered the day the first motor car drove through town, an event that brought all the villagers outside to watch. He remembered when a packet of cigarettes cost one penny. He remembered learning to surf off the coast of South Africa, and how strange he found it that black locals were forced to use a separate beach from whites.
He was drawn to the water at an early age, fishing and swimming at the local brook. Later in life, he would regularly swim in the warm waters off the West Australian state coast, only stopping when he turned 100.
The first world war was raging when Choules began training with the Royal Navy, just one month after he turned 14. In 1917, he joined the battleship HMS Revenge, from which he watched the 1918 surrender of the German high seas fleet, the main battle fleet of the German navy during the war. "There was no sign of fight left in the Germans as they came out of the mist at about 10am," Choules wrote in his autobiography. The German flag, he recalled, was hauled down at sunset. "So ended the most momentous day in the annals of naval warfare," he wrote. "A fleet of ships surrendered without firing a shot."
Choules and another Briton, Florence Green, became the war's last known surviving service members after the death of American Frank Buckles in February, according to the Order of the First World War, a US-based group that tracks veterans.
The machine is controlled by punch cards, which you can see here.The Analytical Engine – conceived in 1837 – remains one of the greatest inventions that never was as Babbage died before he could see out its construction. However, John Graham-Cumming, a programmer and science blogger, now hopes to realise Babbage’s vision by raising £400,000 to build the giant brass and iron contraption. He plans to use Babbage’s original blueprints for the device, which are contained in a collection of the inventor’s notebooks held at the Science Museum in London. The campaign has already attracted 1,600 supporters who have pledged funds to kick-start the project. Elements of the engine have been built over the last 173 years, but this would be the first complete working model of the machine.
Never underestimate the selling power of nostalgia. Ironically in a field like high tech, it's even more pleasing to consumers. A fansite has already been set up to hail the arrival of old-new Commodore and Amiga (which Commodore is also reviving - see here) computers. This is typical Millennial Retro-Futurism, where the combination of old and new tech makes a product hot again. According to the Commodore site, the new version lets you open the old blue BASIC screen and play all the "8-bit era" games. I have a feeling that Commodore just made a lot of Gen X men very happy, along with everyone else.The new Commodore 64, which will begin shipping at the end of the month, has been souped up for the modern age. It comes with a 1.8 gigahertz dual-core processor, an optional Blu-ray player and built-in ethernet and HDMI ports. It runs the Linux operating system but the company says you can install Windows if you like. The new Commodore is priced between $250 to $900.
The company’s Web site says that the new Commodore 64 is “a modern functional PC,” and that although the guts of the device have greatly improved, the exterior is “as close to the original in design as humanly possible.” Most people would not be able to visibly tell the old or new versions apart, it says.
“The response has been completely dramatic,” Mr. Altman said. “We’ve been averaging about five registrations per second on our Web site. This is from people giving us their name and e-mail address to be kept abreast of updates on the new Commodore.”
It looks like an architectural fantasy from a world far in the future, but Michael Hansmeyer's complex column design is so real you can touch it.
His work is composed of sixteen million faces and made from 2,700 layers of cardboard. It is the result of a cutting-edge computational process and people's responses to it are just as improbable.
"Some people say it looks like a reptile, some people think it looks like an underwater creature and other people bring up the Gothic," said Hansmeyer, an architect and computer scientist based at the Swiss Federal Institute of Technology in Zurich.
The incredible complexity of the column's fractal surface is the product of what is known as a "subdivision algorithm," a process that used a computer program to divide and sub-divide the the facets of a classical Doric column.
