In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena.

EAST LANSING, Mich. — Having natural habitat in farming areas that supports ladybugs could help increase their abundance in crops where they control pests and help farmers reduce their costs, says a Michigan State University study.
MADISON – Drawing on powerful computational tools and a state-of-the-art scanning transmission electron microscope, a team of University of Wisconsin-Madison and Iowa State University materials science and engineering researchers has discovered a new nanometer-scale atomic structure in solid metallic materials known as metallic glasses.
UPTON, NY – Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential, either by releasing harmful carbon dioxide into the atmosphere or requiring rare and expensive chemical elements such as platinum.
The cyclone that brought about the devastating winds that battered the UK in the great storm of October 1987 was exceptional in both its strength and path across the south of the country.
This is the finding of a new study which has analysed the places where sting jets – an area that develops in some cyclones and causes strong surface winds – appear in the North Atlantic and how often they do so.
PASADENA, Calif.—For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault—both during an earthquake and at times of "rest"—in order to know more about how a particular region may behave in the future. Now, researchers at the California Institute of Technology (Caltech) have developed the first computer model of an earthquake-producing fault segment that reproduces, in a single physical framework, the available observations of both the fault's seismic (fast) and aseismic (slow) behavior.
Using ice-penetrating radar instruments flown on aircraft, a team of scientists from the U.S. and U.K. have uncovered a previously unknown sub-glacial basin nearly the size of New Jersey beneath the West Antarctic Ice Sheet (WAIS) near the Weddell Sea. The location, shape and texture of the mile-deep basin suggest that this region of the ice sheet is at a greater risk of collapse than previously thought.
An international research team led by Virginia Tech Associate Professor Boris Vinatzer and Giorgio Balestra of the University of Tuscia in Italy has used the latest DNA sequencing technology to trace a devastating pathogen back to its likely origin.
The other zoo project is the creation of Team Koolookamba. All of its members are freshmen: Sarah Frazier, Adam McMullen, Andrew Markham, Joseph Mapula and Calvin Tsay. Allison Garza, a junior mechanical engineering student, was the team's apprentice leader.
Their challenge was to design a feeder for giraffes that is safe and prevents the animals from consuming the hay it contains too quickly.
Alexandria, VA – Volcanism is often implicated in periods of abrupt cooling. After the 1991 eruption of Mount Pinatubo in the Philippines, for instance, global temperatures dropped by half a degree Celsius due to airborne particulate matter blocking solar radiation. However, these effects don't normally last more than a few years. Yet, a recent study blames volcanism for a 500-year cold period referred to as the Little Ice Age.
May, 8, 2012 - The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change.
The overwhelming majority of proteins and other functional molecules in our bodies display a striking molecular characteristic: They can exist in two distinct forms that are mirror images of each other, like your right hand and left hand. Surprisingly, each of our bodies prefers only one of these molecular forms.
This mirror-image phenomenon — known as chirality or "handedness" — has captured the imagination of a UCLA research group led by Thomas G. Mason, a professor of chemistry and physics and a member of the California NanoSystems Institute at UCLA.
During the six years following the withdrawal of the analgesic co-proxamol in the UK in 2005, there was a major reduction in poisoning deaths involving this drug, without apparent significant increase in deaths involving other analgesics. These are the findings of a study by Keith Hawton of the University of Oxford, UK and colleagues and published in this week's PLoS Medicine.
With the age of the incandescent light bulb fading rapidly, the holy grail of the lighting industry is to develop a highly efficient form of solid-state lighting that produces high quality white light.
