With more young Canadians considering self-employment amid a high youth unemployment rate, entrepreneurship programs are facing growing demand. Applications to Futurpreneur, the national organization that finances young Canadian ...
Phys.org / How well do past extinctions predict extinction risk today?
In the last few centuries, mammals and other animals have been going extinct at least 100 times faster than they did before humans arrived on the scene. So who will be next? Which species are most likely to survive, and which ...
Phys.org / Bipartisan majorities in US favor banning glyphosate
Two-thirds of Americans favor banning the use of the herbicide glyphosate, the active ingredient in the popular weedkiller Roundup, on crops grown in the United States, according to a nationally representative survey conducted ...
Medical Xpress / Multiple working hypotheses could clarify COVID-19 origins debate
A Viewpoint article published in the journal BioScience argues that the contentious debate over the origins of SARS-CoV-2 could benefit from a well-established scientific approach for weighing competing explanations.
