Ep. 83: “Big Picture Zika” Featuring Dr. Hongjun Song

Jan 17, 2017
Dr. Hongjun Song, director of the Johns Hopkins Stem Cell Program and neural stem cell researcher, discusses organoids and how they let scientists test causality in human brain development. He explains rapid, collaborative Zika research using stem-cell models, high-throughput drug screening, and how stem cells can model wider Zika impacts and potential therapeutic strategies.

Significant Drop In US Cancer Death Rates

  • Cancer death rates in the U.S. have declined 25% since 1991, largely from reduced smoking and better early detection and treatment.
  • This steady ~1.5% annual decline saved ~2.1 million lives between 1991 and 2014, with largest drops in lung, breast, prostate, and colorectal cancers.

Ring Vaccination Showed Promising Ebola Protection

  • An experimental Ebola vaccine (rVSV-ZEBOV) given in a ring-vaccination trial in Guinea showed zero infections 10–84 days post-shot among ~5,800 vaccinated participants.
  • The ring design vaccinated contacts of cases; 23 infections occurred among ~4,500 unvaccinated/delayed controls, supporting strong preliminary efficacy.

High School Science Interest Varies By Race

  • About 40% of U.S. high school seniors say they want a science career, but interest varies by race/ethnicity, with Asian/Pacific Islanders most likely and Black students least likely.
  • These differences correlate with performance patterns and suggest early educational disparities underlie STEM workforce gaps.
