Ash Cloud Reminds Us That We Should All Be Afraid Of Volcanoes

From The Telegraph:

Eyjafjallajökull's giant cloud of ash is a nuisance, but a supervolcano's catastrophic eruption could threaten the fabric of civilisation, says Kate Ravilious.

Every so often the Earth chooses to remind us that we really aren't in control of this planet. The volcanic eruption in Iceland, which began on Wednesday, is just such a reminder. As ash spews out across northern Europe, grounding all flights across Scandinavia and the UK, we begin to realise how powerless we humans are.

The Biggest Bangs In History

From New Scientist:

The colossal Toba supervolcanic eruption 74,000 years ago was big – but not the biggest in Earth's history. Here's our rundown of chart-topping blasts from the past.


The Tunguska event

One of the 20th century's most notorious bangs happened at 7.14 am on 30 June 1908. At that moment, something exploded with enormous force over the Tunguska river in Siberia, Russia.

The resulting shock wave flattened trees over an area of 2000 square kilometres, and people tens of kilometres away were knocked off their feet.

Water - Another Global 'Crisis'?

Sharper, more intense rains may reduce the water available to farmers

From The BBC:

If you look at the numbers, it is hard to see how many East African communities made it through the long drought of 2005 and 2006.

Among people who study human development, it is a widely-held view that each person needs about 20 litres of water each day for the basics - to drink, cook and wash sufficiently to avoid disease transmission.

Yet at the height of the East African drought, people were getting by on less than five litres a day - in some cases, less than one litre a day, enough for just three glasses of drinking water and nothing left over.

Behind The Air Force's Secret Robotic Space Plane

Behind The Air Force's Secret Robotic Space Plane -- Popular Mechanics

Move over NASA. The U.S. Air Force has spent decades on the concept: an unmanned space plane that can be used to spy, reposition satellites, possibly even bomb targets, then return to base. A successful launch next week could turn that vision into a reality.

When the engines of a 19-story Atlas V ignite in April at Cape Canaveral Air Force Station in Florida, the liftoff will look like any other for the workhorse launch vehicle. After about 4 minutes, the engines will cut off and the rocket's first stage will fall away, freeing the second stage to boost the upper section of the rocket into low Earth orbit.

Climatologists Ponder Earth's Missing Heat

From Science A Go-Go:

Astonishingly, climatologists can't account for roughly half of the heat that is believed to have built up on the Earth in recent years. "The heat will come back to haunt us sooner or later," lament National Center for Atmospheric Research (NCAR) scientists in an article in the journal Science.

The scientists believe that satellite sensors, ocean floats, and other instruments used to measure energy are inadequate to track this "missing" heat, which may be building up in the deep oceans or elsewhere in the climate system. "The reprieve we've had from warming temperatures in the last few years will not continue. It is critical to track the build-up of energy in our climate system so we can understand what is happening and predict our future climate," said NCAR scientist Kevin Trenberth, the article's lead author.

From Live Science:

The plume of ash from Iceland's Eyjafjallajökull volcano, which is now inching across Europe's skies, is creating vivid red sunsets while thwarting airline travel plans. The phenomenon could last for days, and depending on how long the volcano continues to erupt, it could spread volcanic clouds all around the Northern Hemisphere, a scientist says.

The volcanic sunsets might even be glimpsed from the United States if the volcano keeps erupting, but chances for that are slim, experts say.

Green-Eyed Monster: Why Women Can be Literally Blinded By Jealousy

Green-eyed-monster: jealousy, of the type enjoyed by Gabrielle and Carlos in Desperate Housewives, has been shown to affect women's ability to see

From The Daily Mail:

It's hard to see things clearly when you fall victim to the green-eyed monster. And sometimes jealousy can make it hard to see at all.

Researchers found that a woman can fail to notice things in front of her when distracted by the possibility that her husband or boyfriend is attracted to someone else.

Psychologists suggest this reveals something profound about social relationships and perception.

When Black Holes Go Rogue, They Kill Galaxies

A powerful jet from a supermassive black hole is blasting a nearby galaxy in the system known as 3C321 (Image: (NASA/CXC/CfA/D.Evans et al.; Optical/UV: NASA/STScI; Radio: NSF/VLA/CfA/D.Evans et al., STFC/JBO/MERLIN)

From New Scientist:

Massive black holes may be kicking the life out of galaxies by ripping out their vital gaseous essence, leaving reddened galactic victims scattered throughout the universe. While the case is not yet closed, new research shows that these black holes have at least the means to commit the violent crime.

It was already known that "supermassive" black holes at the centre of most galaxies sometimes emit vast amounts of radiation. But nobody had a good idea how common such violence is. A snapshot of the universe doesn't give enough information to judge this because the activity of the black holes is thought to be intermittent, depending on how much nearby matter they have to feed on.

Infected XP Owners Left Unpatched

From The BBC:

Some of the latest security updates for Windows XP will not be installed on machines infected with a rootkit virus.

A rootkit is sneaky malware that buries itself deep inside the Windows operating system to avoid detection.

Microsoft said it had taken the action because similar updates issued in February made machines infected with the Alureon rootkit crash endlessly.

The latest updates can spot if a system is compromised by the Alureon rootkit and halt installation.

Iceland Eruption: New Satellite Image of Volcanic Ash Cloud

This image, acquired on 15 April 2010 by Envisat's Medium Resolution Imaging Spectrometer (MERIS), shows the vast cloud of volcanic ash sweeping across the UK from the eruption in Iceland, more than 1000 km away. The ash, which can be seen as the large grey streak in the image, is drifting from west to east at a height of about 11 km above the surface Earth. (Credit: ESA)

From Science Daily:

ScienceDaily (Apr. 15, 2010) — A vast cloud of volcanic ash has been sweeping across parts of northern Europe from the eruption of a volcano in Iceland. The European Space Agency's Envisat satellite has imaged the ash cloud, showing for example the extent over the UK, more than 1,000 kilometers away.

Carried by winds high up in the atmosphere, the cloud of ash from the eruption of the volcano near the Eyjafjallajoekull glacier in southwest Iceland has led to the closure of airports throughout the UK and Scandinavia, with further disruption in northern Europe expected later.

What Was Different About China's Quake?

From Live Science:

The earthquake that struck China in the early hours of the morning was different than some of the major temblors that have struck around the world so far this year in that it occurred in the middle of one of Earth's tectonic plates, instead of at the junction between them.

The 6.9-magnitude quake, according to estimates by the United States Geological Survey (USGS), struck at 7:49 a.m. local time (2349 GMT, 7:49 p.m. EDT) near the area of Yushu in Qinghai province. This area is part of the Tibetan Plateau, which stands over 3 miles (5 kilometers) above sea level.

Icelandic Volcano’s Ash Plume As Seen From Space

From Wired Science:

A NASA satellite captured an image of the ash plume from the Eyjafjallajokull volcano’s Wednesday eruption. We can see the ash plume from the event sweeping east just north of the United Kingdom en route to Norway.

The plume has disrupted air travel in western Europe, The New York Times reports, because of (well-founded) fears that the silicates in the ash could turn into molten glass inside planes’ jet engines.
