An international team of scientists, including Dr. Alex Dunhill from the University of Leeds, has found that although the mass extinction in the Late Triassic period wiped out the vast proportion of species, there appears to have been no drastic changes to the way…
The environmental impact of hydropower generation in the Amazon may be greater than predicted, according to new University of Stirling research. The study suggests that estimates of biodiversity and carbon losses associated with tropical hydropower may be higher…
Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of…
Astronomers at Lowell Observatory observed comet 41P/Tuttle-Giacobini-Kresak last spring and noticed that the speed of its rotation was quickly slowing down. A research team led by David Schleicher studied the comet while it was closer to the Earth than it has ever…
A new study by the US Geological Survey and Centers for Disease Control and Prevention estimates about 2.1 million people in the United States. may be getting their drinking water from private domestic wells considered to have high concentrations of arsenic,…

Building on existing information and databases relating to volcanic fatalities, scientists from the University of Bristol have, for the first time, been able to classify victims by activity or occupation and look at the distance of their death from the volcano. It…
On May 29, 2006, mud started erupting from several sites on the Indonesian island of Java. Boiling mud, water, rocks and gas poured from newly-created vents in the ground, burying entire towns and compelling many Indonesians to flee. By September 2006, the largest…
The Earth’s interior is still a mystery to us. While we have sent missions to probe the outer reaches of our solar system, the deepest boreholes on Earth go down to only a few kilometers. The only way to learn what’s going on deep inside our planet, in…
Over the last decades, the stratospheric polar vortex has shifted towards more frequent weak states which can explain Eurasian cooling trends in boreal winter in the era of Arctic amplification. When the strong winds that circle the Arctic slacken, cold polar air…
