Rising Metal Prices Prompt Ban on Melting and Export of Coins

The United States Mint, concerned that rising metal prices could lead to widespread recycling of pennies and nickels, has banned melting or exporting them. The Mint is also testing dozens of cheaper alternative metal compositions in the expectation that Congress will mandate a change when it meets in the new year. According to calculations by the Mint, the metal value of pennies, which are made of copper-coated zinc, is now more than one cent. The metal value of 5-cent coins, made from a copper-nickel blend, is up to 7 cents. Adding in the costs of manufacturing means the Mint now spends 1.73 cents for every penny and 8.74 cents for every nickel it makes

Berkeley to be First City to Regulate Nanotechnology

Nanotechnology, the use of subatomic materials as microscopic building blocks for thousands of consumer products, has turned into a big business so quickly that few are monitoring its effects on health and the environment. So the government of Berkeley, California, is intending for the city to be the first to step into the breach and try to regulate this industry

New York Times Adds Sharing Tool

The New York Times unveiled a new service that allows readers to quickly post stories that they find on the newspaper’s Web site to Digg, Facebook and Newsvine. It marks the first time that the country’s third-largest newspaper has added a news-sharing tool to its Web site, allowing readers to develop conversations and post comments about specific stories. Readers will be able to add headlines and a small portion of text to the social media sites by clicking on the logos of Digg, Facebook and Newsvine

Wikia Gives Away Web Sites

Wikipedia founder Jimmy Wales said his company, Wikia, is ready to give away all the software, computing, storage and network access that web site builders need to create community collaboration sites. Wikia, a commercial counterpart to the non-profit Wikipedia, will go even further to provide customers — bloggers or other operators who meet its criteria for popular web sites — 100 per cent of any advertising revenue from the sites they build

Bandwidth Hogs Leap Roadblocks

Emerging internet file-sharing services have begun to derail attempts by some wireless internet providers to weed-out bandwidth hogs on their services. Managing director of Sydney-based wireless ISP BigAir Jason Ashton said there was nothing the company could do to stop the traffic and pointed to Rapid Share, a web-based file-sharing system, as an example of one of the new breed causing headaches for the company’s technical staff

Llamas Recruited to Fight against Biological Threats

Llamas are not just for transportation anymore. It turns out that the animals’ blood could be useful for detecting all sorts of maladies in the surrounding environment — from deadly pathogens to industrial emissions. A research effort has done just that, manipulating a rare type of antibody found in llamas to make an inexpensive and diverse biosensor

Phase Memory Beats Flash

Flash memory and hard-disk drives could face a challenge from a new chip technology, dubbed phase-change memory, being developed by a group of companies led by IBM. The companies claim the technology does a better job of storing songs, pictures and other data on iPods and digital cameras than current flash memory, and could someday replace disk drives. The companies have built a prototype device that runs 500 times faster than today’s flash memory while using half as much power to write data to a memory cell

New World Record Achieved in Solar Cell Technology

US Department of Energy (DOE) Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced that with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive and integral part of our nation’s energy mix

Pirates Hack Vista’s Registration Features

Hackers are distributing a file that they say lets users of the corporate version of Microsoft’s Windows Vista operating system get around the software’s anti-piracy mechanisms. Windows Vista must be activated, or authorised by Microsoft, before it will work on a particular machine. To simplify the task of activating many copies of Vista, Microsoft offers corporate users special tools, among them Key Management Service (KMS), which allows a company to run a Microsoft-supplied authorisation server on its own network and activate Vista without contacting Microsoft for each copy. The software Microsoft.Windows.Vista.Local.Activation.Server-MelindaGates lets users spoof that KMS process, allowing them to activate copies of the enterprise editions of Vista, its creators say. The hacked download is available online on sites including The Pirate Bay and other file sharing sites

CSIRO Demonstrates Fastest Wireless Link Yet

The CSIRO demonstrated the world’s fastest wireless radio link by transmitting sixteen full quality DVD streams over a 250m link and only using a quarter of the available bandwidth. The CSIRO ICT Centre announced that it has achieved over six gigabits per second over a point to point wireless connection with the highest efficiency (2.4bits/s/Hz) ever achieved for such a system
