A Practical Way to Make Invisibility Cloaks

A new printing method makes it possible to produce large sheets of metamaterials, a new class of materials designed to interact with light in ways no natural materials can. For several years, researchers working on these materials have promised invisibility cloaks. Metamaterials that interact with visible light have previously not been made in pieces larger than hundreds of micrometers. Metamaterials are made up of intricately patterned layers, often of metals. Rogers has developed a stamp-based printing method for generating large pieces of one of the most promising types of metamaterial, which can make near-infrared light bend the "wrong" way when it passes through. Materials with this so-called negative index of refraction are particularly promising for making superlenses, night-vision invisibility cloaks, and sophisticated waveguides for telecommunications.he Illinois group starts by molding a hard plastic stamp that's covered with a raised fishnet pattern. The stamp is then placed in an evaporation chamber and coated with a sacrificial layer, followed by alternating layers of the metamaterial ingredients—silver and magnesium fluoride—to form a layered mesh on the stamp. The stamp is then placed on a sheet of glass or flexible plastic and the sacrificial layer is etched away.

TR10: Neuron Control

Karl Deisseroth's genetically engineered "light switch," which lets scientists turn selected parts of the brain on and off. It's control your neural cells with flashes of a light. In Deisseroth's psychiatry practice at the Stanford Medical Center, Deisseroth sometime treats patients who can't walk, talk, or eat. Intensive treatments, s can literally save such patients' lives, but often at the cost of memory loss, and other serious side effects. Deisseroth, who is both a physician and a bioengineer do things better ways was to control the neural cels.

Social Search, without a Social Network

"The company added social features that will let your friends help determine what ranks high in the search results you see. The approach requires Google to know the social connections of its users something that so far is not a core feature of the company's products or uppermost in the minds of people using them". Google's new social tool is the +1 button, which it wants you to click to signal which search results and Web pages you appreciate. If you use this tool your life for searching would be easier.

Reprogrammable Chips Could Enable Instant Gadget Upgrades

"The new chips—made by a startup called Tabula—are a cheaper, more powerful competitor to an existing type of reprogrammable chip known as a field programmable gate array (FPGA)".This chip can be reconfigured to implement new designs, thus allowing device hardware to be upgraded. The technology needed to build stacked, 3-D chips is still restricted to research labs. Instead Teig found a way to make a chip with just one level behave as if it were eight different ones stacked up. Cycling between up to eight different layouts at up to 1.6 billion times per second.

Researchers use LCD projector for mind control

The Georgia Institute of Technology have managed to use inexpensive components from ordinary liquid crystal display (LCD) projectors to control both the brains and muscles of tiny organisms such as worms.Hang Lu and graduate students Jeffrey Stirman and Matthew Crane are the people who is using LCD projectors to control the brains and muscles of tiny organisms.Hang Lu is an associate professor in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology.To control brain circuitry they are using red, blue, and green light from the project. They use the light to move the organism.

Electronic in class

Should we turn off and put away all Cell Phones, ipods, and electronic devices during class?

I think we should and should't because sometime we need them. We should because it create distraction in class and your not paying attention. We should't because we could use Cell Phone to search information on the internet. Also we could use a calculator in the phone to do math work.

When Exercise Is Too Much of a Good Thing

This article was a study of 27 endurance athletes vs. 20 non-endurance athletes. "The different groups underwent a new type of magnetic resonance imaging of their hearts that identifies very early signs of fibrosis, or scarring, within the heart muscle. Fibrosis, if it becomes severe, can lead to stiffening or thickening of portions of the heart, which can contribute to irregular heart function and, eventually, heart failure'.
