CT scan of Earth links deep mantle plumes with volcanic hotspots

Scans prove that plumes of hot rock anchored at core-mantle boundary rise to form island chains

04-Sep-2015

Seismologists have produced for the first time a sharp, three-dimensional scan of Earth's interior that conclusively connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains like Hawaii, Samoa and Iceland. Essentially a computed tomography, ...

Finding biomarkers for early lung cancer diagnosis

20-Aug-2015

Lung cancer patients are often diagnosed only when their disease is already at an advanced stage and hard to treat. Researchers at the West Coast Metabolomics Center at UC Davis are trying to change that, by identifying biomarkers that could be the basis of early tests for lung cancer. Lung ...
