Despite 300 years of research, and a recent renaissance in the study of their biological make-up, the mysterious, marauding teleosauroids have remained enduringly elusive. Scientific understanding of this distant cousin of present day long snouted gharials has been hampered by ...
In a new study focused on Denmark, a global leader in wind energy - a relatively mature and low-cost renewable technology - researchers found that government policies have been the primary driver of that industry's growth and development. ...
Researchers seek to understand the genetic, sociopolitical and cultural changes surrounding the formation of the eastern Eurasian Steppe's historic empires. The study analyzes genome-wide data for 214 ancient individuals spanning 6,000 years and discusses the genetic and cultural changes that ...
For the first time, scientists have visualized a new class of molecular gates that maintain pH balance within brain cells, a critical function that keeps cells alive and helps prevent stroke and other brain injuries. These gates, called proton-activated chloride ...
Scientists have noted instances of leaf-cutter bees using plastic waste to construct their nests and one research group suggested such behavior could be an 'ecologically adaptive trait' and beneficial recycling effort. Other scientists say no; such behavior is harmful to ...
As health care costs balloon in the U.S., experts say it may be important to analyze whether those costs translate into better population health. A new study analyzed existing data to find a dividing line - or ''threshold - for ...
