The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.
COVID-19 isn’t humanity’s first encounter with a coronavirus, so named because of the corona, or crown-like, protein spikes… Read more
One of the most promising areas of human cancer research is the study of signal transduction, or cell signaling. Communication between and within cells in the body is accomplished through signal transduction, as stimuli generated in one part of an organism travels through the circulatory system and initiates a response in specific target cells. As cells… Read more
Evolutionary theory has long held that natural selection largely operates at the level of individuals. Findings from Northern Arizona University researchers, recently published in the Annual Review of Ecology, Evolution, and Systematics, suggest that selection can also occur at multiple levels to shape whole communities. This multi-level selection arises from the interactions of key species that cascade to alter communities and ecosystems.
For example, unraveling the evolution of complex forest communities that… Read more
Northern Arizona University researcher Jeff Foster is leading an international effort to study and track the spread of one of the most important infectious diseases in humans and livestock worldwide. Brucellosis infects an estimated 500,000 people and millions of animals each year – cattle, pigs, sheep, goats – resulting in long-term illness and significant economic loss, though very little is known about… Read more
As climate warming stokes longer fire seasons and more severe fires in the North American boreal forest, being able to calculate how much carbon each fire burns grows more urgent. New research led by Northern Arizona University and published this week in Nature Climate Change suggests that how much carbon burns depends… Read more
From pesticides to chemical weapons, from marshlands to battlefields, Frank von Hippel, ecotoxicology professor in the Northern Arizona University Department of Biological Sciences, traces the efforts of scientists to end famine and plagues, and to wage war, in his new book, The Chemical Age: How Chemists Fought Famine and Disease, Killed Millions, and Changed Our Relationship with the Earth, which was recently published by University of Chicago… Read more
