About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But the crater it left behind in the Gulf of Mexico was a literal hotbed for life enriching the overlying ocean for at least 700,000 years, according to research published today in Nature Communications.

About 131 million years ago, an 11-foot-long ichthyosaur slammed snout first into the seafloor and was rapidly buried by sediments — a sequence of events that helped preserve not only her skeleton, but that of her unborn baby, along with the remains of her last meal.  These details are part of a new study from an international team published in the Journal of Vertebrate Paleontology about the pregnant marine reptile, which the team named Fiona.

Utah's locally sourced dust pollution carries far more hazardous elements than natural dust blown in from Great Basin, potentially threatening Salt Lake City’ water supplies, according to new research led by University of Utah.

A deep learning-based scheme is proposed for automated and efficient processing of teleseismic phases.

1. The validation with two teleseismic phases, PcP and PKiKP, demonstrate high detection accuracies and low picking errors.

2. Deep-learning picking of first peaks is more accurate than picking first breaks of teleseismic phases.

3. This proposed scheme would enhance mining of teleseismic phases and probing of Earth's interior structures and their dynamics.
