A Johns Hopkins Bloomberg School of Public Health analysis estimates that more than 70 million Americans ages 50 and older currently suffer from at least… Read more
There’s a buzz of extraterrestrial activity going on in Room 230 of the Physical Sciences Building at NAU.

Wildflowers splashed across a meadow in different sizes, shapes and colors offer more than just beauty. The natural mix of plant species in an ecosystem—its biodiversity—helps it grow faster and cycle nutrients more efficiently. These ecosystem functions also deliver life-sustaining services on which humans rely, such as purifying water and providing food, fuel and oxygen.
Biodiversity is declining around the world… Read more

These whales were hunted nearly to extinction over the last 300 years for their blubber, which was used to produce oil. Fortunately, these species are repopulating, but because they reproduce slowly, their… Read more
