UMD-led study is first to link racism-related factors and cellular age

COLLEGE PARK, Md. – A new University of Maryland-led study reveals that racism may impact aging at the cellular level. Researchers found signs of accelerated aging in African American men who reported high levels of racial discrimination and who had internalized anti-Black attitudes. Findings from the study, which is the first to link racism-related factors and biological aging, are published in the American Journal of Preventive Medicine.

Racial disparities in health are well-documented, with African Americans having shorter life expectancy, and a greater likelihood of suffering from aging-related illnesses at younger ages compared to whites. Accelerated aging at the biological level may be one mechanism linking racism and disease risk. (more…)

Germs in Space: Preventing Infection on Long Flights

By Science, , , , ,

On a long spaceflight unique conditions including microgravity could give microbes the upper hand, but not if astronauts and their spacecrafts are properly prepared. In a new paper, infectious disease expert Dr. Leonard Mermel brings together a broad base of research to come up with specific recommendations for keeping astronauts safe in deep space

PROVIDENCE, R.I. [Brown University] — The cabin of a spacecraft halfway to Mars would be the least convenient place — one cannot say “on earth” — for a Salmonella or Pneumococcus outbreak, but a wide-ranging new paper suggests that microgravity and prolonged space flight could give unique advantages to germs. What’s a space agency to do? Brown University and Rhode Island Hospital infectious disease expert Dr. Leonard Mermel offers several ideas. (more…)
