New battery coating could improve smart phones and electric vehicles

The problem with lithium ion batteries made with metal is that during charge cycles they uncontrollably grow dendrites, which are microscopic fibers that look like tree sprouts. The dendrites degrade the performance of the battery and also present a safety issue because they can short circuit the battery and in some cases catch fire.

Physicist declassifies rescued nuclear test films | Lawrence Livermore National Laboratory

"You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films," Spriggs said. "We know that these films are on the brink of decomposing to the point where they'll become useless. The data that we're collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They're made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data."

'Answers were off by 30 percent'

From its inception, the project presented a series of hurdles. It took several years to locate the films, and when Spriggs did get his hands on the first few, he didn't have a scanner that could reproduce the optical density on the films. It took about a year to convert a Hollywood-style scanner into one that could provide the level of scientific accuracy required. Then he had to locate the data sheets for the test, because without knowing the camera location, its speed and focal length, he wouldn't be able to analyze the films. Once Spriggs did complete the first scans and roll his sleeves up for the analysis, he discovered that much of the data published were wrong. All the films would need to be reanalyzed.

The Downsizing Uprising | Outside Online

The Downsizing Uprising | Outside Online

In the past five years, thousands of people have been taking simple to an extreme, ditching their three-bedroom homes for micro-abodes of less than 500 square feet. Tiny homes are popping up across the country—sleek glass boxes, log sheds on wheels, converted shipping containers, modern pods built by hand. You can take tiny home building courses online and buy tiny home building plans. There's an annual tiny house conference and even a new online dating network for tiny home dwellers, aka "tiny love mates" (no offense?). Splashy digital slide shows and documentaries like Tiny: A Story about Living Small and Small Is Beautiful glamorize the simplicity of mini-living.

The Downsizing Uprising

The benefits to going small are huge: Tiny homes cost on average $23,000 to build, easing the financial burden of a big mortgage. Downsizing eliminates clutter and limits spending and consumption. In some cases, smaller houses allow you to live off the grid, in remote locations, closer to trails and back country access. And when your house isn't much bigger than a storage shed, you'll naturally spend more time outside, like Laura LaVoie, whose al fresco kitchen in her 120-square-foot North Carolina home—a wooden bar-top with cookware stored below in plastic tubs—isn't much different from our camping kitchen. Not having to mow the lawn or spend your Saturday vacuuming 2,500 square feet means more time for travel and adventure.

The pain of prebiotics? | Dr. William Davis

The pain of prebiotics? | Dr. William Davis

The average American obtains 3-8 grams of prebiotic fibers from their diet, about half from grains. We, of course, cut out all grains, compensate for the loss and increase prebiotic fiber intake (over time) to the ideal intake of around 20 grams per day for full health benefits.

Lincoln's comments about Money and Greed are just as accurate today.

"The money power preys upon the nation in time of peace and conspires against it in times of adversity. It is more despotic than monarchy, more insolent than autocracy, more selfish than bureaucracy. I see in the near future a crisis approaching that unnerves me, and causes me to tremble for the safety of our country. Corporations have been enthroned, an era of corruption will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people, until the wealth is aggregated in a few hands, and the republic is destroyed."

Lincoln continued to fight against the central bank, and some now believe that it was his anticipated success in influencing Congress to limit the life of the Bank of the United States to just the war years that was the motivating factor behind his assassination.

Smart Glasses! via Kurzweil

Abstract of Tunable-focus lens for adaptive eyeglasses

We demonstrate the implementation of a compact tunable-focus liquid lens suitable for adaptive eyeglass application. The lens has an aperture diameter of 32 mm, optical power range of 5.6 diopter, and electrical power consumption less than 20 mW. The lens inclusive of its piezoelectric actuation mechanism is 8.4 mm thick and weighs 14.4 gm. The measured lens RMS wavefront aberration error was between 0.73 µm and 0.956 µm.

Bumblebees Are Listed as Endangered Species For the First Time: Here's How You Can Help

If you have a garden or other plants minimize your use of pesticides. Systemic pesticides like neonicotinoids are taken up by the vascular systems of plants. This means bees and other pollinators are exposed to the poison long after a product has been applied when they feed on the plants’ nectar and pollen.
