From Popular Science:

If you’ve been anywhere near a television or Web enabled device in the last week (and you must have been), you know that a volcanic eruption in Iceland has grounded airline flights across Europe and even halted a few flights into the northeastern-most areas of Canada. What you probably don’t know is how to pronounce the name of the volcano (Eyjafjallajökull) or why an eruption in Iceland is grounding flights in London, Madrid and Berlin.

From Live Science:

ScienceDaily (Apr. 18, 2010) — The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases.

The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the world's oceans over the past 50 years has penetrated into the oceans' interior changing deep-ocean salinity patterns.

Will The Iceland Volcano Change The Climate?

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 Live Science:

The vast plume of material spewing from this week's eruption of an Icelandic volcano is reddening sunsets and clouding skies across Europe. If the eruptions continue and get bigger — a possibility given the explosive history of Iceland's volcanoes — even the global climate could be affected. But the current eruption is too wimpy to have any significant impact, scientists say.

The eruption of Iceland's Eyjafjallajökull volcano may be treating European sky watchers to spectacular sunsets and hampering air travel due to the ash and gas it has spewed into the atmosphere. But "there will be no effect on climate," said Alan Robock of Rutgers University, who studies the effects of volcanic eruptions on climate.

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.

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.

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.

From Time Magazine:

Allergy sufferers like to claim — in between sniffles — that each spring's allergy season is worse than the last. But this year, they might actually be right.

Thanks to an unusually cold and snowy winter, followed by an early and warm spring, pollen counts are through the roof in much of the U.S., especially in the Southeast, which is already home to some of the most allergenic cities in the country. A pollen count — the number of grains of pollen in a cubic meter of air — of 120 is considered high, but in Atlanta last week the number hit 5,733, the second highest level ever recorded in the city.

Why We Can't Do 3 Things At Once

When humans pursue two goals A and B concurrently, the two frontal lobes divide for representing the two goals and related actions simultaneously. The anterior most part of the frontal lobes enables to switch back and forth between the two goals, i.e. executing one goal while maintaining the other one on hold. This inter-hemispheric division of labor explains why humans appear unable to accurately carry out more than two tasks at one time. Credit: Etienne Koechlin, INSERM-ENS, Paris, France, 2010.

From Live Science:

For those who find it tough to juggle more than a couple things at once, don't despair. The brain is set up to manage two tasks, but not more, a new study suggests.

That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled.

Shh, the National Security Agency has developed a software tool that detects thumb drives or other flash media connected to a network, and any federal agency can get a copy free -- no box tops or coupons required.

The NSA provided a brief tantalizing description of its USBDetect 3.0 Computer Network Defense Tool in the unclassified part of its fiscal 2011 budget request.

Space Storms Could Knock Out National Grid And Sat Navs

From The Telegraph:

Space storms caused by the Sun could knock out power supplies and satellite navigation systems in Britain, claim scientists.

The solar flares and sunspots throw massive clouds of electrically charged gas at the Earth which cause power surges and throw compasses into disarray.

The weather in space has been through an unprecedented calm period in the last century but the researchers believe we could be entering a more volatile period.

From The BBC:

Data from Europe's Venus Express probe suggests that Earth's neighbour may still be able to erupt volcanoes.

Relatively young lava flows have been identified on the planet's surface by the spacecraft's infrared instrument.

The flows show up as having a different composition to the surrounding surface material.

Entangle Qubits For A True Random Number Machine

From New Scientist:

PURE randomness is surprisingly difficult to create, even if you draw on the inherent randomness of quantum mechanics. Now, though, a "true" random number generator is on the cards, which may help create the ultimate cryptographic messages.

Existing quantum random number generators are only as reliable as their parts. For example, some devices send single photons through a beam-splitter and record the path taken, but a pattern could emerge over time if the beam-splitter comes to favour one direction or the materials degrade. A new number generator produces random strings of numbers without the worry of such flaws, because it relies on the inherently random behaviour of two quantum-entangled objects.

Evidence Of First Virus That Infects Both Plants And Humans

Tree Afflicted With Chestnut Blight Don't worry. Far as anyone knows, blight still isn't contagious for humans. James Bowe, via Flickr.com

From Popular Science:

From rabies to bird flu to HIV, diseases passing from animals to humans is a well-known phenomenon. But a virus jumping from plants to humans? Never. At least, that's what doctors thought until Didier Raoult of the University of the Mediterranean in Marseilles, France, discovered that the mild mottle virus found in peppers may be causing fever, aches, and itching in humans. If validated, this would mark the first time a plant virus has been found to cause problems in people.
