Among people who have a stroke in Canada, immigrants were admitted to the intensive care unit (ICU) at similar rates to long-term residents or people who were born in Canada, but they were more likely to have longer stays ...
Phys.org / Giant impact could have formed an intact moon within five hours, simulations suggest
New Southwest Research Institute (SwRI) modeling, conducted in collaboration with scientists at the University of Arizona, shows fundamental differences in how the moon may have formed from the giant impact that created the ...
Phys.org / Peacock-like displays outpace antlers and tusks in evolutionary change, model suggests
Many animal species, ranging from peacocks and birds of paradise to some lizards, fish and beetles, display physical features or ornaments that can attract potential mates. These ornaments can include colorful plumage, elaborate ...
Phys.org / One unexplained event could hint at heavy dark matter
An unexplained signal detected by the world's most sensitive dark matter experiment could mark a major breakthrough in the hunt for the elusive substance, according to an analysis involving scientists from the University ...
