Science Daily: June 20, 2013 — Université Laval researchers have developed a highly effective method for converting CO2 into methanol, which can be used as a low-emissions fuel for vehicles. The team led by Professor Frédéric-Georges Fontaine presents the details of this discovery in the latest issue of the Journal of the American Chemical Society. Researchers have been looking for a way to convert carbon dioxide into methanol in a single step using energy-efficient processes for years. "In the presence of oxygen, methanol combustion produces CO2 and water," explained Professor Fontaine. "Chemists are looking for catalysts that would yield the ...

Science Daily: But don't try it at home yet -- the components in the battery tested by scientists at the University of Maryland are a thousand times thinner than a piece of paper. Using sodium instead of lithium, as many rechargeable batteries do, makes the battery environmentally benign. Sodium doesn't store energy as efficiently as lithium, so you won't see this battery in your cell phone -- instead, its low cost and common materials would make it ideal to store huge amounts of energy at once, such as solar energy at a power plant. Existing batteries are often created on stiff bases, which are too brittle to withstand the swelling and shrinking that happens as electrons are ...

Article 12 of the UN's Universal Declaration of Human Rights states that "no one shall be subjected to arbitrary interference with his privacy, family, home, or correspondence." It's that last one that's gotten everyone's attention lately. Just how private is your correspondence online? Depending on your politics, NSA whistleblower Edward Snowden is either a vile turncoat or a revered hero, but either way he has advice on how to stay two steps ahead of the NSA. He held an awesome "press conference" of sorts on The Guardian's website, taking written questions from readers and typing out his answers online. We were most intrigued by his response to ...
Do We Spend Too Much on Sarah Murnaghan?

Saving this little girl's life was a miracle of science—and an act of defiance against an efficiency-obssessed healthcare policy. Sarah Murnaghan is the 10-year-old girl Pennsylvania girl suffering from cystic fibrosis who received a lung transplant—but only after a public outcry, a congressional hearing, and then a court order. The girl is now recovering from the surgery. Sarah’s story can be seen in many dimensions, but here are three to usefully consider: first, the compelling human—and humanitarian—interest of the case; second, the positive role played by advancing medical science; and third, the implicit repudiation of the bipartisan health-policy ...

The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them. To make the microbatteries, a team based at Harvard University and the University of Illinois at Urbana-Champaign printed precisely interlaced stacks of tiny battery electrodes, each less than the width of a human hair. "Not only did we demonstrate for the first time that we can 3-D-print a battery, we demonstrated it in the most rigorous way,"said Jennifer Lewis, Ph.D., senior author of the study, who is also the ...

ScienceDaily: June 17, 2013 — A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America. Published in Geology, new research led by Monash University geologists has detected the first evidence that a passive margin in the Atlantic ocean is becoming active. Subduction zones, such as the one beginning near Iberia, are areas where one of the tectonic plates that cover Earth's surface dives beneath another plate into the mantle -- the layer just below the crust. Lead author Dr João Duarte, from the School of Geosciences said the team mapped the ocean floor and ...
The Continuing Collapse of the Global Warming Hoax

While the nation tries to come to grips with the cascade of scandals involving the Obama administration, a significant phenomenon has been occurring. It is the demise of the global warming/climate change hoax that has driven national and international policies since the 1980s. Directed from within the bowls of the most corrupt international organization on planet Earth, the United Nations, the hoax originally generated the Kyoto Protocols in December 1997 to set limits on the generation of carbon dioxide (CO2) emissions. The UN’s climate charlatans claimed that CO2 was causing the Earth to dramatically warm. It was a lie. The U.S. Senate unanimously refused to ratify it and, in 2011, ...

This post branches off our NSA surveillance tracker, for ongoing coverage of the NSA leaks. NSA leaker Edward Snowden's formal education stopped with a GED, a fact that the New York Times' David Brooks and others have spun into a caricature of him as a loner or outsider. In fact, Snowden's lack of formal credentials made him mainstream, and maybe even the wave of the future. The Brookings Institution reported in a paper titled "The Hidden STEM Economy" that half of the nation's workers in the fields of science, technology, engineering, and math don't have or need a bachelor's degree. They do their work with an associate's degree or even just ...

Even though I am just using it as a live cd at the moment and it's not on my hard drive yet, I am thoroughly impressed with Linux Mint. The Linux I had been using for years was having sound issues that I just couldn't get resolved--it would play cd's on the dvd drive but I had no sound with youtube and skype. And I am a youtube and skype junkie. While skype is not on the live cd of Linux Mint it is available for it. I downloaded the iso last night and burned it to a dvd so I have only had it going for a little while this morning but so far so good and I will probably wipe my hard drive and install this one. If you want to read more about it here is a link to The Linux Mint ...

The scientists have created a flexible plastic film that acts as a catalyst to begin splitting water with low energy input. UOW scientists have developed a novel way to turn sea water into hydrogen, for a sustainable and clean fuel source. Using this method, as little as five litres of sea water per day would produce enough hydrogen to power an average-sized home and an electric car for one day. The research team at UOW’s Australian Research Council Centre of Excellence for Electromaterials Science (ACES) have developed a light-assisted catalyst that requires less energy input to activate water oxidation, which is the first step in splitting water to produce hydrogen fuel.

WASHINGTON, June 10 (Xinhua) -- Five of 13 major crop pests have evolved resistance to Bt corn and cotton, crops engineered to be toxic to certain insects, as of 2010, compared with only one in 2005, a study said Monday. Researchers at the University of Arizona reported in the journal Nature Biotechnology that while the increase in resistance was expected, the main question was how fast the insects evolve resistance and why. They analyzed data from 77 studies of 13 pest species in eight countries on five continents. Three of the five cases of resistance are in the United States, where about half of the world 's Bt crop acreage is planted. The new study found that in the worst ...

Science Daily: May 29, 2013 — Go to about any public square, and you see pigeons pecking at the ground, always in search of crumbs dropped by a passerby. While the pigeons' scavenging may seem random, new research by psychologists at the University of Iowa suggest the birds are capable of making highly intelligent choices, sometimes with problem-solving skills to match. Share This: ? The study by Edward Wasserman and colleagues centered on the "string task," a longstanding, standard test of intelligence that involves attaching a treat to one of two strings and seeing if the participant (human or animal) can reel in that treat by pulling the correct string.

May 27, 2013 — Surprisingly the answer is yes. With the technology of today it is possible to use environmental friendly formic acid in fuel cell powering your mobile phone or laptop. Physicist Florian Nitze, Umeå University in Sweden, has in his thesis developed new catalysts to improve the capacity of these fuel cells. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run. The technology is already commercially available but formic acid fuel cells still suffer from low power and lifetime. The effect of a catalyst is to reduce the energy loss and to increase the rate of the chemical reactions, which leads to a higher ...
