Opening up the last part of the spectrum

Also possible applications in livestock sex detection. © Muro - Fotolia.com New European research on the last, hidden part of the electromagnetic spectrum is producing new, safe and non-destructive tests for medicine, security and industrial quality control.

Terahertz waves occupy the part of the spectrum between light and radio, specifically between infrared and millimetre waves. With wavelengths of 0.1-1mm, THz waves can be used like light or x-rays to create detailed images of solid objects. They have the useful property of passing easily through packaging and clothes, and since they are non-ionising they are safer than x-rays.

But THz waves can probe the content of objects as well as their shapes, thanks to their ability to respond to chemical properties. This is because their frequency range of 0.3-3THz matches the natural molecular vibrations of many common substances and biological materials.

Add these two properties together and you have a scanner that can not only detect a hidden package, but also show what is inside. New European research on THz waves could enable applications that include detecting tumours beneath the skin, a new and powerful kind of microscope for biological research, and quality control in semiconductor and pharmaceutical factories, as well as smart security scanners.

Internet Advertising Revenues in Q3 ''08 at Nearly $5.9 Billion

The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers LLP (PwC) today announced that Internet advertising revenues reached almost $5.9 billion for the third quarter of 2008, representing an 11 percent increase over the same period in 2007. While double-digit annual growth continues, the quarter-to-quarter curve remains relatively flat compared to recent past performance. The Q3 2008 figures, published in the IAB Internet Advertising Revenue Report, are 2 percent higher than the Q2 2008 results. Set against strong economic headwinds in the U.S. economy, Q3 ''''''''08''''''''s $5.9 billion represents nonetheless the second-highest quarter results ever. For the first nine months of 2008, revenues totaled $17.3 billion, up from $15.2 billion in the same period a year ago and surpassing the record set in the first nine months of 2007 by nearly 14 percent.

Study: Mobile phones to be primary Internet device by 2020

Nearly four out of five experts agreed with this scenario, according to an online Pew survey which formed the basis of the report. Pew surveyed 578 leading Internet activists, builders and commentators, identified through various technology associations as well as an "extensive canvassing of scholarly, government and business documents from the period 1990-1995 to see who had ventured predictions about the future impact of the Internet." A few of the experts polled were Nicholas Carr, author of the Rough Type blog and The Big Switch; Havi Hoffman of the Yahoo Developer Network; Michael Botein, founding director of the Media Law Center at New York University Law School; and several members of the ICANN board.

The Future of the Internet III

A survey of internet leaders, activists and analysts shows they expect major tech advances as the phone becomes a primary device for online access, voice-recognition improves, artificial and virtual reality become more embedded in everyday life, and the architecture of the internet itself improves. They disagree about whether this will lead to more social tolerance, more forgiving human relations, or better home lives.
