Magnetic navigation is rapidly emerging as a useful technology in the field of interventional cardiology. Precise control of the direction of a guide wire or a device in three-dimensional space offers a means to access vessels and areas of the heart that are often challenging to access with conventional methods. In this comprehensive Review, we detail the development of magnetic navigation technology and how this tool has been adapted for use during percutaneous coronary intervention

MIT Invention Serves Low-Income Customers

"Cheaper is better." Although 90% of the new technology invented at places like the Massachusetts Institute of Technology serve the richest 10% of the world, there is also a lab in which students can address simple problems.

There is a catch. The solutions must be affordable for customers whose income is less than USD $1 per day. So far so good: They've come up with irrigation systems that can be bought piecemeal and expanded as the farmer's income goes up, stoves that burn fuel more completely and backpacks that can be used to carry water long distances.

Green books meet reality, competition and snags

I remember reading about these on the MIT website last year. A US company pledged to sell laptops to children in poor countries for only $100. They said that they could meet this price largely by eliminating redundant programming but also by filling only very large orders. The books are very durable, powered by a hand crank, and can network with each other wirelessly.

Nature provides some news, though
