New chip captures power from multiple sources: light, heat and vibrations

Researchers at MIT have taken a significant step toward battery-free monitoring systems — which could ultimately be used in biomedical devices, environmental sensors in remote locations and gauges in hard-to-reach spots, among other applications.

Previous work from the lab of MIT professor Anantha Chandrakasan has focused on the development of computer and wireless-communication chips that can operate at extremely low  levels, and on a variety of devices that can harness power from natural light, heat and vibrations in the environment. The latest development, carried out with doctoral student Saurav Bandyopadhyay, is a chip that could harness all three of these ambient power sources at once, optimizing power delivery.

Scientists Create Molecule to Make Teeth Cavityproof

Scientists have discovered a new molecule that will make your teeth cavityproof and may change dental care forever. They have appropriately named it Keep 32—for your 32 teeth—and it can kill the bacteria that produces cavities in 60 seconds flat.

José Córdoba—a researcher at Yale University—and Erich Astudillo—from the Universidad de Santiago, Chile—claim that this molecule can be added to any dental care product, from toothpaste to mouthwash. In fact, they say it can be added to anything, even candies and chewing gum.

Obama gives himself control of all communication systems in America

US President Barack Obama quietly signed his name to an Executive Order on Friday, allowing the White House to control all private communications in the country in the name of national security.

President Obama released his latest Executive Order on Friday, July 6, a 2,205-word statement offered as the “Assignment of National Security and Emergency Preparedness Communications Functions.” And although the president chose not to commemorate the signing with much fanfare, the powers he provides to himself and the federal government under the latest order are among the most far-reaching yet of any of his executive decisions.

Arable Land Shortage and the Case for Agriculture and Farmland Investing

One of the major reasons for our bullishness on farmland investing is the availability of quality farmland. As the graph below from the UN Food and Agriculture Organization (FAO) clearly demonstrates, the amount of arable farmland has already shrunk and will continue to do so.

 

China has actually been a particular victim of this trend. To take a more specific example of this trend. China currently contains 20pc of the world’s population, but only 7pc of its arable farmland. Unfortunately for the Chinese, China has already been losing arable farmland at an alarming rate. According to this article from the English language China Daily, the amount of arable farmland in China has fallen sharply.

Bernanke Announces Unquantitative Easing

Treasury Department Spokesmen said that the amount to be added to the money supply will be 'too much to count'. They added that they had lost count. 

Unquantitative Easing refers to the creation of new money injected into the existing money supply in order to stimulate the economy. If the economy is stimulated, it may achieve orgasm. If the economy is not stimulated, the result may be an anti-climax, which often shows itself in a steady rise and fall in the idle hands of unemployment.
