collision with another planetary body created earths iron

New theories about nature of Earth’s iron

In a study published March 20, 2017 in Nature Communications, an international team of scientists challenges the prevailing theory that the unique nature of Earth’s iron was the result of how its core was formed billions of years ago. The study opens the door...

calbuco eruption expanded ozone hole to record size study

Calbuco's eruption expanded ozone hole to record size

A new study argues that eruption of the Chilean volcano Calbuco on April 22, 2015 stretched the Antarctic Ozone Hole, the thinnest portion of the ozone shell that shields Earth from harmful radiation, to a record size nearly as large as Africa. It did so by ejecting...

One of the greatest mass extinctions caused by volcanic eruptions

One of the greatest mass extinctions caused by volcanic eruptions

Scientists have linked global mass extinction at the Permian-Triassic boundary some 250 million years ago to an ice age caused by the activity of the first volcanism in the Siberian Traps. The research paves the way for a new vision of the Earth's climate...

solar storms trigger surprising phenomena close to earth

Solar storms trigger surprising phenomena close to Earth

A new research shows that eruptions on the Sun’s surface not only send bursts of particles into Earth’s atmosphere, but - contrary to previous belief - also remove electrons across large areas. The new knowledge increases our understanding of solar...

fifth world food lost over eating waste study

Fifth of world's food lost to over-eating and waste, study finds

Almost 20% of the food made available to consumers is lost through over-eating or waste, a study suggests. The world population consumes around 10% more food than it needs, while almost 9% is thrown away or left to spoil, researchers say. Efforts to reduce the...
