One of the first applications built to find and remove malware and spyware, Ad-Aware's reputation is well-justified. The latest version continues the publisher's tradition of adroitly addressing user concerns, but isn't yet perfect.

Building on the improvements made in version 8, former Ad-Aware users should be glad to hear that the program installs faster than it used to. Without a doubt, though, this version of Ad-Aware improves greatly on what has come before. It loads faster during your boot cycle, and scans are faster. Empirical tests noted that while the Quick Scan finished in less than 10 … Read more

Germany has the high-end headphone market covered, as Beyer Dynamic, Sennheiser, and Ultrasone are all headquartered there.

Ultrasone is the newcomer of the group, but it's hardly new. It was founded in 1991 in Tutzing, close to the Alps in southern Germany. The headphones are manufactured in the U.S., Germany, Austria, and Taiwan.

Ultrasone has just announced a new flagship model, the HFI-2400 ($329). It features Ultrasone's S-Logic technology that promises to create "natural surround sound" by reducing pressure on the eardrum up to 40 percent. The new headphone also features ULE-technology that reduces electro-magnetic … Read more

WASHINGTON, D.C.--The question over whether cell phones pose a health risk has been debated for years, and researchers say the final answer could still be years away.

Since the wireless industry's early days, there have been fears that cell phones could be harmful to your health. Some 600 studies have been conducted on the health effects of cell phone use, but the results have been conflicting.

Several reputable organizations, including the World Health Organization and the National Cancer Institute, say there's no conclusive evidence that using cell phones can harm your health. Other independent research, meanwhile, … Read more

A collaborative of international electromagnetic radiation (EMR) watchdogs, including Powerwatch and the EMR Policy Institute, sent a paper to government leaders and media Tuesday detailing several design flaws in a major but oft-delayed telecom-funded Interphone study.

Now consumers get to wonder yet again whether the message behind the paper, "Cellphones and Brain Tumors: 15 Reasons for Concern, Science, Spin and the Truth Behind Interphone," is legitimate or the result of overzealous conspiracy theorists.

The paper's main conclusions are: There is a "significant" risk of brain tumors from cell phone use; EMR exposure limits that have … Read more

For bone cancer patient Nicole McLaughlin to get proton-beam radiation therapy--a treatment to which she owes her life--it took traveling across the country to what then, in 1999, was the only facility providing such technology.

But new research being developed at Lawrence Livermore National Laboratory, which could reduce the size of proton accelerator machines from that of a football field to that of a traditional X-ray machine, could soon make proton therapy more easily accessible to all.

Better-known X-ray radiation goes all the way through the body and can cause healthy cell death, which could be potentially catastrophic depending on … Read more

No more telling Mom you can't talk because your cell phone is "about to die"--it soon could be charging itself as you speak.

The Nokia Research Centre in Cambridge, England, is working on a prototype system that would eliminate the traditional cell phone charger.

The system collects energy from ambient radio waves emitted by antennas, TV masts, Wi-Fi transmitters, and the like. This might all sound uber-scientific, but we've been using this technology for years. Have you ever exited a store, only to hear the beep, beep, beep of an accusing alarm system? Many retailers … Read more

The first instinct when confronted with a radiological explosive device may be to turn tail and run, but the new Demron-W Nuclear/Ballistic Shield affords the opportunity to stick around and save the day.

The Demron suppression blanket provides total protection against ballistics, improvised explosive devices, dirty bombs, spills, and all types of radiological and nuclear incidents, according to Miami-based manufacturer Radiation Shield Technologies (RST).

It acts as a portable shield, tailored to reduce emissions from contained high-energy sources such as Cesium-137, and neutron sources and Americium-Beryllium. It's perfect for covering undetonated radiological dispersal devices, RST says.

The material, … Read more

A turbo-charged engine, 21-inch wheels, Bluetooth, and 600-watt THX speakers are fine, but for the SUV owner who desires everything, how about a Mobile Nuclear Radiation Detection System?

Raytheon is offering the Sports Utility Vehicle-Based Radiation Detection System, which uses advanced spectroscopic technology to detect and identify nuclear radiation, whether sitting put or on the move.

Deploy quickly and set up your own checkpoint to screen for nuclear weapons, improvised nuclear devices, and dirty bombs or just cruise and troll for high gamma and stray neutrons. The system incorporates advanced threat identification algorithms that detect and identify most radiological materials.… Read more

Soaring cost estimates for protecting US borders against nuclear smuggling arrived at by the Domestic Nuclear Detection Office (DNDO) are unreliable and could result in "significant" overruns, according to a Government Accounting Agency (GAO) report.

How significant? The projected cost to implement the Radiation Portal Monitor Program has gone from $399 million in 2003, when the Customs and Border Protection was in charge of the project, to $1.3 billion when DNDO took over in 2005. In 2007 the cost of equipping US ports with portal monitors was $1.7 billion. It's now $2.1 billion. But … Read more
