"Copper oxides, also known as cuprates, are the most promising materials for superconductivity. Today, cuprates can be superconductive at temperatures as high as -150 °C. But for many years scientists wondered why they lose superconductivity when concentration of electrons drops below certain level. Most scientist thought that the cuprates gradually became insulators.
Scientists from Université de Sherbrooke discovered that the loss of superconductivity is because of a sudden appearance of a distinct electronic phase in the material that enters into competition with the superconductivity and weakens it. It means, that higher temperature superconductors will be possible if we can get rid of the competing phase. This new approach opens a way to get an ambient temperature superconductivity."
As part of a project developed by San Francisco area start-up WaterFX, a giant solar receiver in Firebaugh, CA, rotates to track the sun and capture its energy. The 377-foot array, however, does not generate electricity, but instead creates heat used to desalinate water. The goal is to tap the abundant, if contaminated, resource in this parched region: the billions of gallons of water that lie just below the surface.
The water is tainted with toxic levels of salt, selenium and other heavy metals that wash down from the nearby Panoche foothills, and is so polluted that it must be constantly drained to keep it from poisoning crops. This, coupled with the record-breaking drought that California is facing means that irrigation costs are going to double or triple as farms are forced to buy water on the spot market.
"Food prices are going to go up, absolutely", said Dennis Falaschi, manager of the Panoche Water District. "This year, farmers in the Panoche district will receive no water. Last year, they received only 20 percent of their allocation", Mr. Falaschi said. In 2012, the allocation was 40 percent. Farmers elsewhere who rely on the State Water Project to irrigate 750,000 acres of farmland will also receive no water in 2014.

"I don't seem to be able to use the 'Submit Story' feature at the moment... I just thought I'd flag a little saga currently unfolding near where I live. An open cut coal mine that supplies coal to a nearby 1600MW power station in Victoria, Australia, has been on fire for over a week. This could threaten electricity generation in the area and might have been deliberately set.
What might be more interesting is the lack of news media attention to it."

"The latest Snowden revelation suggests that Australia's spies are committing economic espionage on Americans, for the benefit of the American government.
The NSA's espionage partners in Australia offered the U.S. intelligence agency surveillance information on an American law firm that was representing the Indonesian government in a trade case against the U.S., according to leaked documents from Edward Snowden's stash.

[Ed. Note] This is another long-denied open secret now documented. One can only wonder what we gve Australia in return. Here is the NY Times article referenced in the above article.
AudioGuy writes "A Guardian reporter, Rebecca MacKinnon, has some interesting insights on how Chinese censorship may be inadvertently leaking into Micosoft's Bing Search engine.
"After conducting my own research, running my own tests, and drawing upon nearly a decade of experience studying Chinese Internet censorship, I have concluded that what several activists and journalists have described as censorship on Bing is actually what one might call "second hand censorship". Basically, Microsoft failed to consider the consequences of blindly applying apolitical mathematical algorithms to politically manipulated and censored web content. The algorithm deployed by Bing may be mathematically sound, but it fails to protect online freedom of expression. Bing failed to take into account the political reality of Chinese government censorship and its broader impact on the shape of the Chinese Internet. Without adjustments to how simplified Chinese websites based outside of mainland China are "weighted," exiled and dissident online voices inevitably lose out. Put it another way: an apolitical mathematical formula automatically amplifies Chinese government censorship to all people searching for simplified Chinese content anywhere in the world, not just in China."
Apparently Google had the same problem, but has managed to write code to prevent these side effects."

"According to Fox News, environmentalists are concerned about the impact of the world's largest solar plant, which is located in the Mojave Desert, on the local bird population. The Ivanpah Solar Electric Generating System (a solar thermal plant) covers nearly five square miles, has approximately 350,000 garage door sized computer controlled mirrors, and has temperatures near the boilers reaching 1000 degrees Fahrenheit. Plant owners NRG Energy Inc., Google Inc., and BrightSource Energy say they have found dozens of dead birds in the complex in the last several months, some with burned or scorched feathers. The plant cost $2.2 Billion to construct, and had been held up in regulatory and wildlife relocation fighting for several years. It has officially been open since Thursday, February 13, 2014."

"Followers of the Penguin, Marcin Iwiński, one of the founders of CD Projekt RED, has spoken out about why the developer of The Witcher series and Cyberpunk 2077 has not yet shown any support towards Linux.
Marcin says: "You know, one of the reasons we have not released The Witcher on Linux is that we most probably have to address five different versions of Linux and this is always terrible to support the quality of the games afterwards. The patches, the updates, and everything. If Steam will deliver a constant Linux environment, call it SteamOS or anything like that, we would love to have our games there because, you know, the more people play our games, the better for us."

"The American Association for the Advancement of Science (AAAS) is providing many interesting news items this week. The BBC reports that the Black Ghost Knifefish has inspired construction of a new robot. The robotic fish would be able to swim in underwater situation where it would be impossible or too dangerous for a human to swim."
Read more below.
"'Today, we don't really have underwater robots that work well in really cluttered conditions or in conditions where vision isn't useful,' said Prof Malcolm MacIver. 'Just consider the sunken cruise ship. It is very dangerous to send divers into such situations where the water can be very cloudy.'
It is the special propulsion technique employed by knifefish that the Northwestern researcher primarily wants to copy: the ripples sent through the long fin on the belly. Undulate one way, and the fish will move forward; undulate the other way, and the direction of travel is reversed. Using counter-propagating waves that meet in the middle, the fish will move vertically."
