Mastery of fire has given humans dominion over the natural world. A Yale-led study provides the earliest evidence to date of ancient humans significantly altering entire ecosystems using fire. The study, published in the journal Science Advances, combines archaeological evidence — dense clusters of stone artifacts dating as far back as 92,000 years ago — ...
Electrons in a solid occupy distinct energy bands separated by gaps. Energy band gaps are an electronic “no man’s land,” an energy range where no electrons are allowed. Now, scientists studying a superconductor compound containing iron, tellurium, and selenium have found that an energy band gap opens at a point where two allowed energy bands ...
A recent McGill study published in Environmental Science and Technology finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the U.S. have been greatly underestimated — by as much as 150 percent in Canada, and by 20 percent in the U.S. Indeed, the research suggests that methane gas emissions from ...

People living in urban areas have a lower risk of developing psychological distress and better overall health if they have more trees within a walkable distance from their homes, an Australian study by University of Wollongong (UOW) researchers has found. In neighborhoods with a tree canopy of 30 percent or more, adults had 31 percent ...
