Indonesia's devastating 2018 earthquake was a rare supershear, UCLA study finds



Posted: 12 Feb 2019 01:22 PM PST


The devastating 7.5 magnitude earthquake that struck the Indonesian island of Sulawesi last September was a rare 'supershear' earthquake, according to a study led by UCLA researchers. Only a dozen supershear quakes have been identified in the past two decades.


Moving artificial leaves out of the lab and into the air



Posted: 12 Feb 2019 01:00 PM PST


Researchers have proposed a design solution that could bring artificial leaves out of the lab and into the environment. Their improved leaf, which would use carbon dioxide -- a potent greenhouse gas -- from the air, would be at least 10 times more efficient than natural leaves at converting carbon dioxide to fuel.


New frog species found on remote Ethiopian mountain



Posted: 12 Feb 2019 11:14 AM PST


A new species of puddle frog (order: Anura, family: Phynobatrachidae, genus: Phrynobatrachus), has just been discovered at the unexplored and isolated Bibita Mountain in southwestern Ethiopia. The research team named the new species Phrynobatrachus bibita sp. nov., or Bibita Mountain dwarf puddle frog, inspired by its home.


Climate of North American cities will shift hundreds of miles in one generation



Posted: 12 Feb 2019 09:00 AM PST


In one generation, the climate experienced in many North American cities is projected to change to that of locations hundreds of miles away -- or to a new climate unlike any found in North America today. A new study and interactive web application aim to help the public understand how climate change will impact the lives of people who live in urban areas of the United States and Canada.


Ice volume calculated anew



Posted: 12 Feb 2019 06:26 AM PST


Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and Antarctic ice sheets. Their conclusion: previous calculations overestimated the volume of the glaciers in High Mountain Asia.


Earth's magnetic shield booms like a drum when hit by impulses

The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research.


Research will help urban planners prioritize bike lanes



Posted: 12 Feb 2019 05:15 AM PST


A new virtual tool could help planners choose the best places to install bikes lanes in cities. The data-based tool builds on previous research that validated the safety benefits of bike lanes for cyclists and motorists.


New deep sea animal discoveries warrant expanded protections in Costa Rican waters



Posted: 11 Feb 2019 03:29 PM PST


Scientists surveyed deep-sea seamounts outside Isla del Coco UNESCO World Heritage site revealing coral communities with surprising diversity.


NASA finds possible second impact crater under Greenland ice



Posted: 11 Feb 2019 03:28 PM PST


A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland.


Arctic sea ice loss in the past linked to abrupt climate events



Posted: 11 Feb 2019 01:40 PM PST


A new study on ice cores shows that reductions in sea ice in the Arctic in the period between 30-100,000 years ago led to major climate events. During this period, Greenland temperatures rose by as much as 16 degrees Celsius.


Connection between home energy efficiency and respiratory health in low-income homes



Posted: 11 Feb 2019 10:14 AM PST


A new study finds people living in drafty homes in low-income, urban communities are at a higher risk of respiratory health issues.
