Lawrence LeBlond for RedOrbit.com The Moon, Earth´s closest companion for more than 4 billion years, is the object of a new theory on how our planet´s own natural satellite was created, reports ScienceNOW. It is scientifically believed that Earth collided with a hypothetical Mars-sized planet called Theia early in its existence producing a disc of magma that orbited Earth and eventually amalgamated to form the Moon. Under this giant impact hypothesis, models show that the...

Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties – atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way...

Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at areas called subduction zones. By analyzing samples of submarine volcanic glass near one of these areas, scientists found unexpected changes in isotopes of hydrogen and boron from the deep mantle. They expected to see the isotope "fingerprint" of seawater. But in volcanoes from the Manus Basin they also discovered...
