In many urban areas, low-income neighborhoods have more mosquitoes, making residents more vulnerable to mosquito-borne diseases. A new study co-authored by scientists at Cary Institute of Ecosystem Studies found that invasive, nonnative plants, which tend to be more common in low-income areas, boosted mosquito populations in Baltimore, MD, and Washington, DC. The results, published in the Journal of Medical Entomology, suggest that cities and their residents could reduce mosquito infestations by planting native tree species.

Researchers with the CHIME/FRB Collaboration found that diffuse “puffs” of ordinary matter fill the vast spaces between galaxies. The findings help explain why physicists’ estimates of the amount of visible matter in the universe are much larger than what we know exists within stars and galaxies.
