A team of researchers at University of Arizona and the University of Toronto have published a study of a rare dementia called primary progressive aphasia, or PPA.
The research linked improved patient outcomes to the brain’s capacity to “recruit” other areas of the brain to make up for deficits.
An international team of researchers has reported what may be the first two isolated, salty, subglacial lakes found on Earth.
The water pockets — one roughly the area of Arizona’s Saguaro Lake, the other about four-fifths the size of the state’s Apache Lake — differ from 400 other subglacial pools in that they are 4-5 times as salty as Earth’s oceans.
Wildfires in the Lower Colorado basin can increase streamflow in the river, even during dry conditions, and even while Arizona endures a 20-plus-year drought, according to a recent study.
The 30-year study examined long-term regional fire effects at 168 sites across the contiguous U.S.
Scientists from the U.S. and Panama have found that some frog species can recover from chytridiomycosis, an infectious disease partly responsible for amphibian die-offs around the world.
