The houses are all eco-friendly and constructed from 3D-printed building blocks made from layers of recycled construction waste and glass fibre and mixed with cement.

Each home costs less than £3,000 to build.

“Microsoft is aware of limited, targeted attacks that attempt to exploit a vulnerability in Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, Internet Explorer 9, Internet Explorer 10, and Internet Explorer 11,” the company said in a security advisory.

According to Microsoft, the attacks have been launched against IE users tricked into visiting malicious websites. Such attacks, dubbed “drive-bys,” are among the most dangerous because a vulnerable browser can be hacked as soon as its user surfs to the URL.

Welcome to the Sharing Economy.

This is the model of the new economy, where anyone with a car ought to be a Lyft contractor (your fare pays what he or she thinks is right but the company is tweeting out “we’ve slashed prices 20 percent”) and anyone with a house or apartment is renting it out on Air BnB and crashing at their boyfriend’s parents’ place.

All of this came about by design. The world is arranged according to the people who arrange things—the people who make money by this arrangement. We’re in our fourth decade of this. The Times reported this week that the American middle class has been surpassed by Canada’s.

And it’s much worse than the New York Times imagines. As Dean Baker points out, the middle classes in most other countries have increased their incomes while getting longer vacations. In the U.S.A.? Not so much.

But this life of hustle—the idea that everything you do, every day, needs to turn a profit or you starve—is familiar to anyone who lives or grew up in an inner city. In Salon today, D. Watkins points to the junkies putting on a fight-show for crack, and the lady who runs the candy/cig shop out of her second floor window, lowering the product down in a pencil box tied to a rope of shoelaces. You’ve seen the guys moving “loosies” and the guys selling the bags from the food pantry.

We have few clues about the consequences of our cumulative exposures. We do know that widespread antibiotic treatments make us more susceptible to invaders by selecting for resistant bacteria.

These risks are now well-known, but I want to lay out a new concern: that antibiotic use over the years has been depleting the pool of our friendly bacteria — in each of us — and this is lowering our resistance to infections. In today’s hyperconnected globe, that means that we are at high risk of future plagues that could spread without natural boundaries from person to person and that we could not stop. I call this “antibiotic winter.”

To explain: In the early 1950’s, scientists conducted experiments to determine whether our resident microbes — the huge number of bacteria that live in and on our bodies, now called our “microbiome” — help in fending off invading bacteria. They fed mice a species of a typical invader, disease-causing salmonella. It took about 100,000 organisms to infect half of the normal mice. But when they first gave mice an antibiotic, which kills both good and bad bacteria, and then several days later gave them salmonella, it took only three organisms to infect them. This isn’t a 10 or 20% difference; it’s a 30,000-fold difference.

That was in mice, but what about humans? In 1985, Chicago faced a massive outbreak of salmonella. At least 160,000 people became ill and several died from drinking contaminated milk. The health department asked victims of the outbreak and unaffected persons, “Have you received antibiotics in the month prior to becoming ill?” People who said yes were five times more likely to become ill than those who drank the milk but hadn’t recently received antibiotics.

People carry a small number of highly abundant bacterial species and a large number of much less common ones. For example, you may carry trillions of Bacteroides thetaiotaomicron in your colon and only a thousand cells, or fewer, belonging to many other species. We are not sure how many rare species any of us has. If you had only 50 cells of a particular type, it would be difficult to detect them against the background of trillions of others.

In a notice earlier this month to the firearms industry, the Bureau of Alcohol, Tobacco, Firearms and Explosives said it was temporarily suspending parts of its computerized system to shore up capacity in part to process the required registration and transfer of National Firearms Act covered weapons, which also include silencers, short-barreled shotguns, short-barreled rifles and some explosive devices.

Between 2005 and 2013, firearms act-related applications “skyrocketed by more than 380%” to nearly 200,000, according to the April 16 memo issued by ATF Deputy Assistant Director Marvin Richardson. The surge has contributed to a backlog of more than 70,000 applications.

As CBS 2’s Maurice DuBois reported Thursday, luxurious kitchens, swimming pools, even gyms are being added to bunkers built just in case of an emergency.

Bomb shelters were a common site in backyards in the Cold War 1950s.

Named Quazi-Zenith Satellite System (QZSS), it is designed to augment Japan’s use of the U.S.-operated Global Positioning System (GPS) satellite service. By precisely correcting GPS signal errors, QZSS can provide more accurate and reliable positioning, navigation, and timing services.

Today’s GPS receivers track the distance to four or more GPS satellites to calculate the receiver’s position. But because of the various errors inherent in the GPS system, location can be off by several meters. In using the data from QZSS to correct the measured distance from each satellite, the accuracy of the calculated position is narrowed down to the centimeter scale.

Trina Solar’s Honey Ultra monocrystalline silicon module reached a new record of 326.3W, which has been independently certified by TUV Rheinland, a leading authoritative certification institution. This result sets a new world record for p-type monocrystalline silicon modules. The monocrystalline silicon module is composed of 60 high-efficiency Honey Ultra monocrystalline silicon cells of 156mm x 156mm, fabricated with a technology developed by Trina Solar and currently in pilot production.

Honey Ultra marks the second generation of Trina Solar’s Honey module technology and this new high-efficiency record significantly extends the previous milestone of 284.7W attained by Trina Solar’s first generation of Honey modules.

The module integrates core technologies including back surface passivation technology and low-resistance connection technology, each of which have been researched and developed by Trina Solar.

…

This new Honey Ultra module marks a key milestone for Trina Solar’s State Key Laboratory of PV Science and Technology since its accreditation in November 2013 and follows the Company’s development of a new Interdigitated Back Contact (“IBC”) cell capable of delivering an industry-leading efficiency of 24.4%.

U.S. officials called on Russia to cease the operations, said Army Col. Steve Warren, a Pentagon spokesman.

“We call upon the Russians to take immediate steps to de-escalate the situation,” Warren said.

Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, spoke with his Russian counterpart on Thursday, but details of their conversation were not released. Defense Secretary Chuck Hagel has tried, without success, to contact Russia’s defense minister.

Ukraine’s air defenses are old but still potent enough, under the right circumstances, to take down Russian aircraft, said Michael O’Hanlon, a military analyst at the Brookings Institution. In fact, drawing fire might be Russia’s intent by entering Ukraine’s airspace.

“I don’t put a deliberate provocation, in order to create a pretext for response and invasion, past Putin at this point,” O’Hanlon said.

The U.S. response to such a move, O’Hanlon said, would be limited, perhaps the sale of arms or sharing intelligence.
