| Mountaintop glacier ice disappearing in tropics around the world Posted: 28 Jun 2021 02:05 PM PDT Mountaintop glacier ice in the tropics of all four hemispheres covers significantly less area -- in one case as much as 93% less -- than it did just 50 years ago, a new study has found. |
| Data from boreholes in plate boundaries could explain slow earthquakes Posted: 28 Jun 2021 09:30 AM PDT Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes. For the first time, researchers use deep-sea boreholes to gauge pressures far below the seafloor. |
| Paleonursery offers rare, detailed glimpse at life 518 million years ago Posted: 28 Jun 2021 08:41 AM PDT All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international team of researchers. |
