Famous paintings help study the Earth's past atmosphere
A team of Greek and German researchers has shown that the colors of sunsets painted by famous artists can be used to estimate pollution levels in the Earth's past atmosphere. In particular, the paintings reveal that ash and gas released during major volcanic eruptions scatter the different colors of sunlight, making sunsets appear more red. The results are published today in Atmospheric Chemistry and Physics, an open access journal of the European Geosciences Union. (2014-03-25)

Now it will become cheaper to make second-generation biofuel for our cars
Producing second-generation biofuel from dead plant tissue is environmentally friendly -- but it is also expensive because the process, as used today, needs expensive enzymes, and large companies dominate this market. Now a Danish/Iraqi collaboration presents a new technique that avoids the expensive enzymes. The production of second generation biofuels thus becomes cheaper, probably attracting many more producers and competition, and this may finally bring the price down. (2014-02-24)

Tree roots in the mountains 'acted like a thermostat' for millions of years
Tree roots in the mountains may play an important role in controlling long-term global temperatures. Researchers have found that temperatures affect the thickness of the leaf litter and organic soil layers, as well as the rate at which the tree roots grow. When the roots reach the rock below the soil, the rock disintegrates, releasing carbon dioxide. Researchers say this process is (2014-02-05)

300,000-year-old hearth found
When did humans really begin to control fire and use it for their daily needs? A team of Israeli scientists discovered in the Qesem Cave, an archaeological site near present-day Rosh Ha'ayin, the earliest evidence -- dating to around 300,000 years ago -- of unequivocal repeated fire building over a continuous period. These findings help answer the question and hint that those prehistoric humans already had a highly advanced social structure and intellectual capacity. (2014-01-27)

Source of Galapagos eruptions is not where models place it
Images gathered by University of Oregon scientists using seismic waves penetrating to a depth of 300 kilometers have found an anomaly that likely is the volcanic mantle plume of the Galapagos Islands. It's not where geologists and computer modeling had assumed. (2014-01-21)

(2014-01-05)

Open-vent volcanoes and the maturation of volcanic hazards study
Understanding and mitigating volcanic hazards is evolving and is increasingly being managed by scientists and engineers in their home countries. Nevertheless, scientists from countries where volcanic hazards are not as immediate are eager to work with them, especially when introducing new technology, which supports infrastructure development. The lure of working at sites of diverse volcanic activity is strong, and participation in international collaborative work during real volcanic crises is especially valuable to young scientists.

Gene 'driver' of Waldenstrom's Macroglobulinemia in up to one-third of patients identified
In nearly one-third of patients with Waldenstrom's Macroglobulinemia, a specific genetic mutation switches on the disease, and a new drug that blocks the defective gene can arrest the disease in animal models, researchers at Dana-Farber Cancer Institute and allied institutions will report at the 2013 annual meeting of the American Society of Hematology. The finding may open the way to clinical trials of the drug in Waldenstrom's patients whose tumor cells carry the mutation. (2013-12-09)

Flipping a gene switch reactivates fetal hemoglobin, may reverse sickle cell disease
Hematology researchers have manipulated key biological events in adult blood cells to produce a form of hemoglobin normally absent after the newborn period. Because fetal hemoglobin is unaffected by the genetic defect in sickle cell disease, these cell culture findings may open the door to a new therapy for the debilitating blood disorder. (2013-12-08)
