The release of a huge amount of methane gas may have caused a massive, prehistoric extinction that gave way to the arrival of dinosaurs as the dominant life form on earth, according to a new study. Micha Ruhl and his team of researchers from the Nordic Center for Earth Evolution at the University of Copenhagen in Denmark suggest that the mass extinction of half of Earth's marine life over 200 million years ago was a result of a huge release of carbon methane into the atmosphere, which led to...

A new study finds that the closing of some European airports last year during and after volcanic eruptions in Iceland was the proper thing to do, and may have saved lives. The eruption of ash from Eyjafjallajokull resulted in the largest closure of European airspace since World War II, with losses estimated at around $2 billion. Concerns about aircraft safety during the eruptions were well founded, as ash particles from the initial phase of the eruptions were particularly abrasive, posing a...

A team of scientists has discovered that the drastic decline in Arctic musk ox populations that began roughly 12,000 years ago was due to a warming climate rather than to human hunting.  "This is the first study to use ancient musk ox DNA collected from across the animal's former geographic range to test for human impacts on musk ox populations," said Beth Shapiro, the Shaffer Career Development assistant professor of biology at Penn State University and one of the team's leaders. ...

Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. A scientific team led by Professor Robert Frei at the University of Copenhagen in Denmark, and including scientists from Newcastle University, UK, and universities in Uruguay and Southern Denmark, have for the first time managed to plot the rise and fall of oxygen levels in the Earth's atmosphere over the last 3.8 billion years. By analyzing the isotopes...

Scandinavian scientists believe they may have discovered a gene that could prevent people from eating levels of the poisonous metal arsenic, which can be absorbed by crops like rice.Apparently a gene, called nodulin26-like intrinsic protein, is responsible for protecting crops by allowing them to absorb silicon in cell walls as a defense against fungal infections."Our observations ... may provide a key to the development of low arsenic crops for food production," wrote the team from the...
