by Mahaa Ahmed Dr. Hildrus Poindexter, a specialist in tropical diseases, epidemiology, and public health, was the first African American to receive both an MD and PhD. He earned his MD from Harvard Medical School in 1929 and his PhD in immunology and microbiology from Columbia University in 1932. Eager to begin his career, Dr. Poindexter applied for a job at a U.S. laboratory in … Continue reading Dr. Hildrus Poindexter — Making a difference through science and inspiration
As the Arctic gets hotter, its landscape releases more greenhouse gases. According to a new study, the warming Arctic soil’s bacteria may diversify and emit even more greenhouse gas than scientists have thought. Continue reading As the Arctic Warms, Soil Bacteria May Diversify and Release More Carbon Dioxide
Researchers at the Pasteur Institute in Paris identified a molecular pathway that links the gut microbiome to mood disorders. Continue reading Bacteria in the Gut can Influence Brain Function and Mood Disorders

Climate change is shifting the preference of ticks from dogs to humans, generating a spike in cases of Rocky Mountain spotted fever. Continue reading Dog Ticks Change Their Appetite with Rising Global Temperatures
Commercial harvesting of plants may have forced them to evolve to camouflage and evade humans. Continue reading Plants Can Camouflage Too, and They’re Hiding from Us
by Wei Lifigures by Rebecca Senft If you’ve ever taken an organic chemistry class, you may know that making chemical compounds can be a long and painful process. Bacteria, however, face no such struggles. After millions of years, these tiny microbes have evolved into the perfect molecule-makers — powerful factories capable of churning out many complex molecules. These molecules are known as bacterial natural products, … Continue reading Bacteria: The drug factory you’d never expect
