US scientists have found that all modern varieties of potatoes can be traced back to a single source – a potato grown in Peru over 7,000 years ago. The team, led by Dr David Spooner of the University of Wisconsin-Madison, who spends two months a year collecting wild potatoes on treks in South America’s mountainous regions analysed the DNA of about 360 potatoes, both wild and cultivated. Dr Spooner said archaeological finds had shown potatoes were being grown in Peru by farmers “more than 7,000 years ago”. Potatoes were brought back to Spain by the conquistadors around 1570, and spread throughout Europe. They were later introduced in North America by British colonists.

Travellers are advised to review any plans to visit Zanzibar during late October and early November 2005. Tanzania will hold a general election on October 30, 2005. Previous elections generally have been peaceful on the Tanzanian mainland, but following the 2000 elections, violent demonstrations occurred on Zanzibar (and Unguja and Pemba) and many people were killed. The demonstrations were not directed at tourists and no foreign visitors were hurt.

Tensions are already rising in Zanzibar during the run up to the October 2005 elections. Opposition party leaders have threatened to stage massive demonstrations if their conditions for a free and fair election are not met. The opposition is calling for peaceful demonstrations, but things can turn violent with little or no warning. If demonstrations do occur, they are not expected to target foreign tourists, however, they could disrupt transportation and communication systems.

American soldiers in Iraq claim they uncovered evidence of a terrorist bomb plot targeting the US. People in New York City are warned to remain on alert amid fears of a terrorist attack on the New York subway system. New York Mayor Michael Bloomberg has ordered increased security on the subway system and warned that the threat – which includes the use of explosives packed in baby strollers – suggested New York’s underground train network and its 4.5 million daily passengers could be attacked within days.

Spotted by webmaster Paul: three robot fish, created by robotics experts from Essex University can be found at London Aquarium. They move around the tank like real fish, and have sensor-based controls, so they can move around the tank, avoiding objects and other fish, and reacting to their environment as a real fish would. Professor Huosheng Hu, of the university’s computer science department, said the aim of creating the fish and having them on display in a public place was to increase awareness about robots’ capabilities. He said the robotic fish, which took three years to create, could also be used in the ocean such as including seabed exploration, detecting leaks in oil pipelines, mine countermeasures, and improving the performance of underwater vehicles.

A tagged great white shark (called Nicole, by researchers – after shark loving actress Nicole Kidman) crossed the Indian Ocean from South Africa to Australia and back again in just nine months. The act of tagging a great white is something of an achievement; several people need to hold the creature still while the satellite tracker is attached.

The conservationists were investigating how far great whites swim, to see what protection measures might be needed to save them from extinction. Great whites were once thought to keep to coastal regions, but this was a trek across a vast expanse of open ocean. The journey was very direct, not some aimless wandering and the stay near Australia was only brief.

The researchers say the fact that they saw a shark make the journey at all – after observing only about 20 animals – suggests it is common behaviour. Their concern is that such migrations make the great whites vulnerable to long-line fishing. It is already known that lesser sharks do get captured and killed this way.

You don't have to go far to encounter trouble!  New research from the UK's Direct Line Travel Insurance indicates that over one in 10 Britons has been robbed while on holiday and a further 27 percent know someone who has. Spain is the country with the highest number of thefts with 38 percent of those who have experienced robberies claiming it happened there.  France is next on the list with 14 percent, Italy seven per cent and Greece five percent.

Money is the most frequently stolen possession (41 percent), followed by purses, wallets, cameras and jewellery.

Be careful what you write whilst on-line in China.  Yahoo was accused last week of helping Chinese authorities identify and imprison a reporter who described government fears about pro-democracy activists.  Shi Tao of China's Contemporary Business News attended a meeting at which an official read a government memo warning of possible social unrest during the 15th anniversary of the 1989 Tiananmen Square massacre.  Using an Internet alias, Shi described the government memo in an email sent to a U.S.-based pro-democracy website, incurring the anger of Chinese authorities.

According to Reporters Without Borders, Yahoo's Chinese division helped local authorities crack Shi's alias, leading to his arrest, two-hour trial, and 10-year prison sentence.  Google, Yahoo, and Microsoft are all competing for a share of the Chinese internet market and all three come under criticism for lowering ethical standards when it comes to free speech.  In June, Microsoft fended off criticism for blocking Chinese bloggers on its sites from using words like “liberty,” “capitalism,” and “human rights.”

Zimbabwe is said to be about to import four endangered Siberian tigers from China for captive breeding.  China had received zebras, elephants and impala as part of an “exchange programme”. Yes, this comes from a country that is rapidly imploding, people being displaced from their homes and land, rampaging inflation and there is not enough to eat.  A local biologist working in Bulawayo, said the plan was “a complete load of garbage”, adding that the country even lacked the resources to look after its own wildlife.
