New Solar-Powered Device Can Pull Water Straight From the Desert Air ( 202

sciencehabit quotes a report from Science Magazine: You can't squeeze blood from a stone, but wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity. The device can produce nearly 3 liters of water per day, and researchers say future versions will be even better. That means homes in the driest parts of the world could soon have a solar-powered appliance capable of delivering all the water they need, offering relief to billions of people. To find an all-purpose solution, researchers led by Omar Yaghi, a chemist at the University of California, Berkeley, turned to a family of crystalline powders called metal organic frameworks, or MOFs. Yaghi developed the first MOFs -- porous crystals that form continuous 3D networks -- more than 20 years ago. The networks assemble in a Tinkertoy-like fashion from metal atoms that act as the hubs and sticklike organic compounds that link the hubs together. By choosing different metals and organics, chemists can dial in the properties of each MOF, controlling what gases bind to them, and how strongly they hold on. The system Wang and her students designed consists of a kilogram of dust-sized MOF crystals pressed into a thin sheet of porous copper metal. That sheet is placed between a solar absorber and a condenser plate and positioned inside a chamber. At night the chamber is opened, allowing ambient air to diffuse through the porous MOF and water molecules to stick to its interior surfaces, gathering in groups of eight to form tiny cubic droplets. In the morning, the chamber is closed, and sunlight entering through a window on top of the device then heats up the MOF, which liberates the water droplets and drives them -- as vapor -- toward the cooler condenser. The temperature difference, as well as the high humidity inside the chamber, causes the vapor to condense as liquid water, which drips into a collector. The findings were published in the journal Science.

Sorry America, Your Taxes Aren't High ( 903

Americans generally feel they're being over-taxed, especially around this time of the year. But is that really true? An article on Bloomberg investigates: The Organization for Economic Cooperation and Development analyzed how 35 countries tax wage-earners, making it possible to compare tax burdens across the world's biggest economies. Each year, the OECD measures what it calls the "tax wedge," the gap between what a worker gets paid and what they actually spend or save. Included are income taxes, payroll taxes, and any tax credits or rebates that supplement worker income. Excluded are the countless other ways that governments levy taxes, such as sales and value-added taxes, property taxes, and taxes on investment income and gains. Guess who came out at the top of the list? No. Not the U.S. At the top are Belgium and France, while workers in Chile and New Zealand are taxed the least. America is in the bottom third.

and it wont result in dogs 2.0

It wasnt just proximity to humans that cause the first domestication event in wolves (or really, several parallel events), but conditions that also resulted animals with less aggression, which was then amplified by captive breeding.

this event isnt structured to provide that reduction in aggression.
but it will provide an increase in guile.

this isnt dogs 2.0
this is coyotes 2.0

proving once again you are neither insightful, nor based in reality.

also, you're fucking stupid if you think the conservatives, pro-business and anti-public as they are, are more representitiive of the people than Obama and his noms were. but then we already established that.
