ExtInked: Tattoos to Save the World

How far would you go to help save an endangered animal? How about allowing someone to jab ink into your skin with tiny needles, 150 times a second? That’s exactly what hundreds of volunteers signed up for last weekend at ExtInked, where people came from far and wide to have one of Britain’s most endangered species permanently tattooed on their body, making them a life long ambassador for that species

Cameroon Leapfrogs Hong Kong in Malware Hosting Blocklist

Cameroon (.cm) web domains supplanted those in Hong Kong as most likely to harbour malware, with more than one in three (36.7 per cent) of domains registered in the West African country hosting viruses or malicious code. The .cm used by Cameroon is a common typo for .com, a factor that security firm McAfee speculates may explain why cybercriminals have set up fake typo-squatting sites that lead to malicious downloads or spyware under the country’s domain

Facebook Tightens Privacy

Facebook is enhancing privacy controls and eliminating its regional framework for online communities as the internet’s most popular social networking service tops 350 million users. Facebook founder Mark Zuckerberg announced the changes and the milestone in a blog post, saying new privacy features will let users determine who gets to see pictures, comments, videos and other material in profiles

Intel Unveils 48-Core Cloud Computing Silicon Chip

Intel has unveiled a prototype chip that packs 48 separate processing cores on to a chunk of silicon the size of a postage stamp. The Single-chip Cloud Computer (SCC), as it is known, contains 1.3 billion transistors, the tiny on-off switches that underpin chip technology. Each processing core could, in theory, run a separate operating system. Currently, top-end chips for desktop computers typically contain four separate processors. Intel and rival AMD will both launch new six-core devices in 2010, allowing computers to simultaneously tackle a number of complex tasks, such as processing graphics

Google to Limit Free News Access

Newspaper publishers will now be able to set a limit on the number of free news articles people can read through Google. The concession follows claims from some media companies that the search engine is profiting from online news pages. Under the First Click Free programme, publishers can now prevent unrestricted access to subscription web sites. Users who click on more than five articles in a day may be routed to payment or registration pages

Online Retailer Topbuy Breaches Spam Act by Sending Emails to Consumers Without Consent

The Australian Communications and Media Authority has issued a formal warning to online retailer Topbuy, following an investigation that found the company had breached the Spam Act 2003 by sending three commercial electronic messages to consumers without their consent. The ACMA formed the view that the breaches it found were indicative of broader systemic issues. The ACMA’s investigation related to complaints alleging that Topbuy had sent emails to people who had previously requested to be unsubscribed from Topbuy’s mailing list or who had not consented to receive commercial electronic messages in the first place. Topbuy claimed in at least one case that it had obtained consent through a family and friends’ referral campaign

Global Surge in Rhino Poaching

Rhino poaching around the world is on the rise despite efforts to protect the animals. The global surge in the illegal trade has been driven by demands from Asian medicinal markets, the study by conservationists concluded. It suggests that a decline in law enforcement is the main reason for the rise in poaching in Africa. The report found that 95% of rhino poaching in Africa since 2006 had occurred in Zimbabwe and South Africa

A New Recipe for Rocket Fuel

Last week researchers from Purdue and Penn State University launched a rocket that uses an unconventional propellant: aluminum-ice. The fuel mix, dubbed ALICE, is made of nano-aluminum powder and frozen water, and gets its thrust from the chemical reaction between the ingredients. The propellant is environmentally friendly, and it could perhaps allow spacecraft to refuel at locations like the moon, where water has been discovered

GE Pact With Vivendi Clears Way for Sale of NBC

General Electric has reached a tentative agreement to buy Vivendi’s 20 percent stake in NBC Universal for about $5.8 billion, helping clear the path to a sale of the television and movie company to Comcast, people briefed on the matter told DealBook. But much remains to be negotiated, these people warned. The Vivendi agreement values NBC Universal at $29 billion, less than the $30 billion or so that GE and Comcast had agreed to last month

German President Refuses To Sign Censorship Law

German federal president Horst Köhler has refused to sign a law to block child pornography that passed Parliament earlier this year, stating that he needs more information. In Germany, the federal president has the right to reject a law only if its passage violated the order mandated by the constitution, or if it is obviously unconstitutional — he can’t veto a law simply because he disagrees with it. The law was passed under a coalition government, but a different coalition took power before the law reached the president’s desk. Political observers guess that the political parties would like to get rid of the law without losing face, but since it has already passed the Parliament, they can’t simply abandon it — via Slashdot

Paper-Thin Batteries Made from Algae

Scientists worldwide are striving to develop thin, flexible, lightweight, inexpensive, environmentally friendly batteries made entirely from nonmetal parts. Among the most promising materials for these batteries are conducting polymers. However, until now these have impractical for use in batteries — for instance, their ability to hold a charge often degrades over use. The key to this new battery turned out to be an often bothersome green algae known as Cladophora. Rotting heaps of this hairlike freshwater plant throughout the world can lead to unsightly, foul-smelling beaches. This algae makes an unusual kind of cellulose typified by a very large surface area, 100 times that of the cellulose found in paper. This allowed researchers to dramatically increase the amount of conducting polymer available for use in the new device, enabling it to better recharge, hold and discharge electricity
