Lava fingerprinting reveals differences between Hawaii's twin volcanoes
— 2 Dec 2011 10:53 | Geology and palaeontologyHawaii's main volcano chains - the Loa and Kea trends - have distinct sources of magma and unique plumbing systems connecting them to the Earth's deep mantle, according to UBC research…
Climate sensitivity to CO2 more limited than extreme projections
— 25 Nov 2011 09:00 | EnvironmentA new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies - and, in fact, may…
Ancient environment found to drive marine biodiversity
— 25 Nov 2011 09:00 | Geology and palaeontologyMuch of our knowledge about past life has come from the fossil record - but how accurately does that reflect the true history and drivers of biodiversity on Earth?…
Earth's core deprived of oxygen
— 23 Nov 2011 19:46 | Geology and palaeontologyThe composition of the Earth's core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements…
Sugar-grain sized meteorites rocked the climates of early Earth and Mars
— 2 Apr 2011 11:34 | AstronomyBombardments of 'micro-meteorites' on Earth and Mars four billion years ago may have caused the planets' climates to cool dramatically, hampering their ability to support life, according…
Astrophysicist: White dwarfs could be fertile ground for other Earths
— 31 Mar 2011 15:03 | AstronomyPlanet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place…
Deep-sea volcanoes don't just produce lava flows, they also explode!
— 29 Mar 2011 16:19 | Geology and palaeontologyBetween 75 and 80 per cent of all volcanic activity on Earth takes place at deep-sea, mid-ocean ridges. Most of these volcanoes produce effusive lava flows rather than explosive eruptions,…
