The fossils of ancient salamander-like creatures in Scotland are among the most well-preserved examples of early stem tetrapods -- some of the first animals to make the transition from water to land. Thanks to new research, scientists believe that these creatures are 14 million years older than previously thought. The...
Study Finds Alaska, Rest of Earth, to Lose Most of Glacier Mass
An international study has found that Earth’s glaciers will lose 76% of their 2020 mass under current climate policy pledges made by nations.
Does Outdoor Air Pollution Affect Indoor Air Quality? It Could Depend on Buildings’ HVAC
We typically spend 80% of our time indoors, where the quality of the air we breathe depends on the age and type of building we occupy, as well as indoor pollution and outdoor pollution sources.
Atlantic Ocean Current Expected to Undergo Limited Weakening with Climate Change
The Atlantic meridional overturning circulation, commonly referred to as the "AMOC," is a system of ocean currents confined to the Atlantic basin that plays a crucial role in regulating Earth's climate by transporting heat from the Southern to the Northern Hemisphere.
Leprosy existed in America long before arrival of Europeans
Long considered a disease brought to the Americas by European colonizers, leprosy may actually have a much older history on the American continent. Scientists reveal that a recently identified second species of bacteria responsible for leprosy, Mycobacterium lepromatosis, has been infecting humans in the Americas for at least 1,000 years,...
Birds nested in Arctic alongside dinosaurs
Spring in the Arctic brings forth a plethora of peeps and downy hatchlings as millions of birds gather to raise their young. The same was true 73 million years ago, according to a new article. The paper documents the earliest-known example of birds nesting in the polar regions.
Save twice the ice by limiting global warming
A new study finds that if global warming exceeds the Paris Climate Agreement targets, the non-polar glacier mass will diminish significantly. However, if warming is limited to 1.5 degrees Celsius, at least 54 per cent could be preserved -- more than twice as much ice as in a 2.7 C...
New Study Analyzes Air Quality Impacts of Wildfire Smoke
The comprehensive research examined air quality in Reno, Nevada during 106 wildfires to illuminate the atmospheric and public health impacts of smoke.
Mid-Air Transformation Helps Flying, Rolling Robot to Transition Smoothly
Specialized robots that can both fly and drive typically touch down on land before attempting to transform and drive away.
