A woman thought she could not have children is now a mother - thanks to a white knuckle rollercoaster ride.

But, after making love in their home, the young couple visited their local entertainment park at Hassloch in Germany where Nayade went on the Expedition GeForce, one of the world's fastest rollercoasters.

One week later her gynaecologist, Dr Thomas Gent, told her she was pregnant.

He said: "We believe that she conceived due to the G force of the rollercoaster ride."

US President George W Bush has declared Friday 16 September a national day of prayer and remembrance for the victims of Hurricane Katrina.

Mr Bush asked agencies in the disaster zone to treat bodies with "dignity and respect", and announced initial aid of $2,000 (£1,090) for displaced families.

Washington has been accused of failing to react swiftly to the disaster.

Some 25,000 body bags are being sent to New Orleans as rescuers begin recovering victims.

Only 23 of the city's normal contingent of 148 pumps are in operation along with three portable pumps.

They are said to be pushing out about 60,000 gallons (228,000 litres) of water per second but water remains in about 60% of the city.

Internet giant Yahoo has been accused of supplying information to China which led to the jailing of a journalist for "divulging state secrets".

Reporters Without Borders said Yahoo's Hong Kong arm helped China link Shi Tao's e-mail account and computer to a message containing the information.

Shi Tao, 37, worked for the Contemporary Business News in Hunan province, before he was arrested and sentenced in April to 10 years in prison.

According to a translation of his conviction, reproduced by Reporters Without Borders, he was found guilty of sending foreign-based websites the text of an internal Communist Party message.

"We already knew that Yahoo! collaborates enthusiastically with the Chinese regime in questions of censorship, and now we know it is a Chinese police informant as well," Reporters Without Borders said in a statement.

The companies say they have to abide by local regulations, and point out that since China is set to be the world's biggest internet market, they cannot ignore it.

As relief workers scramble to provide comfort and succor to the thousands and thousands of people dispossessed by hurricane Katrina, tech relief efforts are hitting snags. Equipment shortages, problems accessing the Internet, and the time it takes to set up computers for refugees to use are all getting in the way of getting people help, but that's not too surprising. This is, after all, a disaster.

What is surprising, however, is the fact that the Federal Emergency Management Agency's (FEMA) online registration site for disaster help is Internet Explorer-only.

Workers on the ground have told Ars Technica that they would prefer to avoid setting up Windows XP workstations because they take longer to setup, and even longer to properly patch and configure for use. You may recall that in an experiment performed last year, a Windows XP SP1 box put on the Internet was compromised in 4 minutes flat.

An Australian court has ruled that the popular file-swapping program Kazaa urged its users to breach copyright.

The Federal Court ordered Kazaa's owners, Sharman Networks, to modify the software to prevent further piracy.

Although the ruling is only enforceable in Australia, the record industry has hailed it as a victory that would resonate around the world.

Kazaa's owners were ordered to modify the software within two months to include filters designed to stop the sharing of copyright material.

"The court has ruled the current Kazaa system illegal," said record industry spokesman Michael Speck said outside the court.

The Rolling Stones' first studio album in eight years has been illegally posted on the internet for download, a British newspaper claims.

A Bigger Bang is due for release today but illegal downloading from several websites could cost the legendary British group a fortune in lost sales, the paper said.

A spokeswoman for the Stones' record company EMI told The Times of London: "The first low-quality files of new Rolling Stones music were found illegally posted on Monday, the same day we began making the new album available for consumers to listen to via radio and streaming."

"It is actually a major achievement to keep an album secure until this close to the commercial release date."

The entire 16-track album is available to listen to on the Stones' website.

SomethingAwful's forum denizens, on the call of site admin Richard "Lowtax" Kyanka, raised over $20,000 dollars to be donated to the Hurricane Katrina relief efforts. This was done via a PayPal donation link, and PayPal has now frozen the account on a twofold basis: one, that there have been reports of "suspicious behavior" from the "buyers," and two, that no shipping records have been provided for the donations. Since so many users are asking for it, SomethingAweful has provided a link for those wishing to still make donations to the Red Cross in the meantime.

What's that, you ask? Evidently, it's when you ignore the terms written on the side of Lexmark printer cartridge box, refilling the cartridge with ink even when the company has designated it "single use only." According to the Ninth Circuit ruling [PDF] this week in ACRA v. Lexmark, opening the package means you agree to Lexmark's wishes. And if you break that agreement, you could face claims under contract and patent law.

As Fred von Lohmann explains it, it's sort of like when you buy those fancy Gillette Sensor razors, then purchase cheap replacement razor heads — except that a court has ruled that if the package says "single use," then by opening it you've agreed you can't have any cheap replacements (but you can buy another Gillette "single use" razor). And that means the company that makes the replacement heads is out of luck, too.

A parasitic worm that makes the grasshopper it invades jump into water and commit suicide does so by chemically influencing its brain, a study of the insects’ proteins reveal.

The parasitic Nematomorph hairworm (Spinochordodes tellinii) develops inside land-dwelling grasshoppers and crickets until the time comes for the worm to transform into an aquatic adult. Somehow mature hairworms brainwash their hosts into behaving in way they never usually would – causing them to seek out and plunge into water.

Once in the water the mature hairworms – which are three to four times longer that their hosts when extended – emerge and swim away to find a mate, leaving their host dead or dying in the water. David Biron, one of the study team at IRD in Montpellier, France, notes that other parasites can also manipulate their hosts' behaviour: "'Enslaver' fungi make their insect hosts die perched in a position that favours the dispersal of spores by the wind, for example."

Encrypted P2P networks will soon make bandwidth management based on deep packet inspection obsolete, says Staselog, a Finnish appliance outfit.

Around 80 per cent of all traffic in the Internet is already P2P. This traffic will increase 1,000-fold in the next five years and most of it will be encrypted P2P, according to a study by Staselog and researchers at Finnish Universities.

Along with next generation file trading networks featuring the use of encryption - so-called darknets - scrambled VoIP traffic will also to the load service provider networks have to support. Staselog's sales pitch is that current approaches to bandwidth management, based on deep packet inspection to detect and throttle P2P, will be unable to cope when most traffic is encrypted - hence the need to introduce different traffic prioritisation techniques.
