[Here is a good list of relief efforts]

The Red Cross is the key aid organisation collecting donations for relief efforts following Japan's earthquake and tsunami.

The Japanese branch of the organisation is overseeing around 80 teams on the ground, but donations are being taken at branches around the world.

A spike in radiation levels at Japan's stricken Fukushima nuclear plant has forced workers to suspend their operation, a government spokesman says.

He was speaking after smoke was seen rising from reactor three. Earlier, a blaze struck reactor four for the second time in two days.

Friday's 9.0-magnitude earthquake and tsunami, which killed thousands, damaged the plant's cooling functions.

The site has also been hit by four explosions, triggering radiation leaks.

'On standby'

SOMA, Japan – Water levels dropped precipitously Monday inside a Japanese nuclear reactor, twice leaving the uranium fuel rods completely exposed and raising the threat of a meltdown, hours after a hydrogen explosion tore through the building housing a different reactor.

Water levels were restored after the first decrease, but the rods remained partially exposed late Monday night, increasing the risk of the spread of radiation and the potential for an eventual meltdown.

The short answer to this is yes. But the effects of such a shift are tiny. The Earth's tilt and rotational spin on its axis as it travels around the Sun causes our seasons. The earthquake in Japan moved the axis of rotation by around 16 cm. That might sound like a lot, but it's small compared to the size of the Earth. 1 degree change to the tilt of the axis of the Earth would mean moving it by around 110 km.

Dr. Daniel McNamara, a seismologist with the U.S. Geological Survey, told The Huffington Post that the disaster left a gigantic rupture in the sea floor, 217-miles long and 50 miles wide. It also shifted Japan's coast by eight feet in some parts, though McNamara was quick to explain much of the coast likely didn't move as far.

WTF ? We haven't left the current one yet.

A move by farmers in developing countries to ecological agriculture, away from chemical fertilisers and pesticides, could double food production within a decade, a UN report says.

Overall, 42% of respondents said they side more with the unions, while 31% took Walker's position. Among those with annual household incomes under $30,000, that split was considerably larger, with 46% supporting the unions, and only 20% supporting Walker. People earning $30,000 to $74,999 per year also backed the unions, 49% to 31%.

Yet among those earning over $75,000 per year, 36% said they backed the unions, while slightly more, 40%, said they stood behind Walker.
