Researchers Take on Atmospheric Effects of Arctic Snowmelt

Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt. The research, led by chemistry professor William R. Simpson, is concerned with the Arctic’s reactive bromine season, which is the period of […]

“Vampires” May have been Real people with this Blood Disorder

Porphyrias, a group of eight known blood disorders, affect the body’s molecular machinery for making heme, which is a component of the oxygen-transporting protein, hemoglobin. When heme binds with iron, it gives blood its hallmark red color. The different genetic variations that affect heme production give rise to different clinical presentations of porphyria — including […]
