The Santiaguito volcano showered sand and ash on Monday over a large area of western Guatemala in an "unusual" and "violent" display, the national seismological institute said.

The institute said winds were carrying the ash in a northeasterly direction from the 2,500 metre (7,500 foot) high volcano in the province of Quetzaltenango, 206 kilometres west of the capital.

The ash plume spread across six provinces, raising fears of damage to crops, the institute said while classes were suspended at schools in three provinces.

Santiaguito's worst eruption occurred in 1929 when 2500 people were killed.

Best of the Web: Remember that Ash Cloud? It Didn't Exist

No ash cloud here: Deep blue skies over London April 16. So, if planes weren't grounded for 6 days because of the "ash cloud"...
Britain's airspace was closed under false pretences, with satellite images revealing there was no doomsday volcanic ash cloud over the entire country.

Skies fell quiet for six days, leaving as many as 500,000 Britons stranded overseas and costing airlines hundreds of millions of pounds.

Estimates put the number of Britons still stuck abroad at 35,000.

However, new evidence shows there was no all-encompassing cloud and, where dust was present, it was often so thin that it posed no risk.

The satellite images demonstrate that the skies were largely clear, which will not surprise the millions who enjoyed the fine, hot weather during the flight ban.

Jim McKenna, the Civil Aviation Authority's head of airworthiness, strategy and policy, admitted: 'It's obvious that at the start of this crisis there was a lack of definitive data.

'It's also true that for some of the time, the density of ash above the UK was close to undetectable.'

Mice Make Own Morphine

Mammals could have opiate factories.

Mammals may possess the biochemical machinery to produce morphine - a painkiller found in the opium poppy, according to a new study.

Meinhart Zenk of the Donald Danforth Plant Science Center in St Louis, Missouri, and colleagues detected traces of morphine in the urine of mice after injecting chemical precursors of the drug. They report their findings today in the Proceedings of the National Academy of Sciences.[1]

Like other opioids, morphine is a potent, potentially addictive pain reliever. Scientists have speculated for decades that animals naturally synthesize morphine because specialized receptors in the brain respond to the drug. Trace amounts of morphine had been found in human urine and cells.[2] But studies using living animals yielded inconclusive results because of possible contamination from external sources of morphine in their food or in the environment.

Yazoo City, Mississippi - Tornadoes ripped through the Southeast on Saturday, killing 10 people in Mississippi and injuring more than a dozen others. Roofs were torn off businesses, homes were splintered, vehicles were overturned and roads were blocked by toppled trees.

Gov. Haley Barbour told The Associated Press there was "utter obliteration" in parts of Yazoo County, an area known for cotton, catfish, blues music and picturesque hills rising abruptly from the flat Mississippi Delta.

Mississippi Emergency Management Agency spokesman Greg Flynn said five people were killed in Choctaw County, including two children. Four victims were in Yazoo County and one was in Holmes County.

More than 15 other counties were also damaged. The swath of debris forced rescuers to pick up some of the injured on all-terrain vehicles the west-central part of the state.

Tornadoes were also reported in Louisiana, Arkansas and Alabama, and the severe weather continued to track eastward.

In Yazoo City about 40 miles north of Jackson, Malcolm Gordon, 63, stood with members of his family peering through a broken window. Above them, the roof was gone, a tree lay across part of the house and power lines stretched across the yard in a neighborhood made up of modest houses and mobile homes on a street that winds around hills and ravines. The smell of shredded pine trees hung the warm breeze.

Giant Deep Sea Jellyfish Filmed in Gulf of Mexico

Giant Jellyfish

Remarkable footage of a rarely seen giant deep sea jellyfish has been recorded by scientists.

Using a remotely operated vehicle (ROV), they captured a video of the huge Stygiomedusa gigantea.

The jellyfish has a disc-shaped bell than can be a metre wide, and has four arms that extend up to six metres in length.

The jellyfish has only been seen 114 times in the 110 years it has been known to science, say researchers.

Professor Mark Benfield from Louisiana State University in Baton Rouge, US, came across the creature as part of the Serpent project, a collaboration between marine scientists and energy companies, including BP, Shell, Chevron and Petrobras, working in the Gulf of Mexico.

Could Icelandic volcano cause famine?

So far it has caused massive travel disruption, but could the Icelandic volcano bring famine and widespread social disorder?

A French historian says it has happened before.

Emmanuel Garnier argues that a volcanic eruption in Iceland in 1783 brought freak weather conditions in Europe that indirectly led to the French Revolution.

Comment: It is hard to be 100% sure about the direct casual effect between the vulcano eruption and the French Revolution, but such a link is surely interesting to consider in the light of current events.

Are we to expect local climate disruption followed by crop failure and food riots and finally some sort of revolution? If so, this time it is likely to be lead by the psychopaths in power, not the common people.

Whale poop is vital to ocean's carbon cycle

Saving endangered baleen whales could boost the carbon storage capacity of the Southern Ocean, suggests a new study of whale faeces. Whale faeces once provided huge quantities of iron to a now anaemic Southern Ocean, boosting the growth of carbon-sequestering phytoplankton.

So says Stephen Nicol of the Australian Antarctic Division, based in Kingston, Tasmania, who has found "huge amounts of iron in whale poo". He believes that before commercial whaling, baleen whale faeces may have accounted for some 12 per cent of the iron on the surface of the Southern Ocean.

Previous studies have shown that iron is crucial to ocean health because plankton need it to grow. "If you add soluble iron to the ocean, you get instant phytoplankton growth," says Nicol. The amount of iron in whale faeces means that protecting Antarctic whales could swell populations of phytoplankton, which absorb carbon dioxide.

Antarctic krill (Euphausia superba) feed on the phytoplankton, concentrating the iron in their tissue. And in turn, baleen whales eat the krill.
