Number joke

Plastics unite to make unexpected metal-like compound

When laid side-by-side the two materials are physically unchanged, but the way electrons behave is subtly altered along the interface where the different materials are in close proximity, says Morpurgo. In tests, they tried cooling down the combined materials, expecting the odd behaviour to disappear because the two plastics become more insulating at lower temperatures.

Instead the interface became a better conductor, just as metals offer less resistance to electricity when they are cooled.

Change IP Country

Proxy. It keeps reloading, though, and thus changing the IP -- tough for streaming stuff.

Globalization must go on

Yes, the benefits of a good safety net are well established, but globalization is not the primary source of trouble for most American workers. Health care problems, bad schools for our children or, in recent times, bad banking practices have all produced greater disruptions — and these have been fundamentally domestic failings.

Albinos doing worse in Tanzania

Police officials are at a loss to explain precisely why there is a wave of albino killings now. Commissioner Paul Chagonja said an influx of Nigerian movies, which play up witchcraft, might have something to do with it, along with rising food prices that were making people more desperate.

The heroes of SARS

In early April, however, a 71 year-old doctor named Jiang Yanyong began to speak out against the official policy. Unlike most Chinese dissenters, Dr Jiang openly identified himself, and made no secret of his role as a senior military doctor in the People’s Liberation Army, and a lifelong member of the Communist Party. Perhaps he owed his doggedness to his advancing years; while he understood the authorities’ efforts to maintain prestige and public order, he was convinced that the free flow of information would be needed to halt the spread of the disease. If SARS were to rampage unchecked among the 1.3 billion Chinese population, the best disease-control efforts of other countries would be in vain.

Overview of successful transit systems

Seventy percent of Curitiba's (Brazil) population uses transit or bikes:

This system is said to be the most efficient, cost-effective public transportation system in the world, and more than 80 countries have adopted it.

Mini buses pick up people from residential neighbourhoods and “feed” them to buses travelling in dedicated bus lanes that circle the city. Passengers alight and get on buses from tube-like bus stops that have outlets such as post offices and public phones. To speed up the movement of buses and passengers, passengers pay their fares at these bus stops rather than on the buses.
