NIH Health Research

A weekly summary of research developments and discoveries at the National Institutes of Health (NIH)
  1. Researchers found changes to DNA in the uterine cells of women with endometriosis that weren’t seen in women without the condition.
  2. Advanced imaging techniques gave insight into the detailed structure of tooth enamel crystals. The findings could lead to new approaches to prevent or reverse cavities.
  3. New techniques dramatically reduced the time needed to process complex images from fluorescence microscopes and also improved their quality.
  4. Older adults with less wealth had sharper declines in many measures of physical and mental health than those with more wealth.
  5. Although most people who recovered from COVID-19 had low levels of antibodies to SARS-CoV-2 in their blood, researchers identified potent infection-blocking antibodies.
  6. Specific gut bacteria influenced eating decisions in worms by affecting their response to odors. The findings give insight into one way gut microbes may affect behavior.
  7. A blood test that measures people’s exposure to different viruses identified those who later developed liver cancer. The test could play an important role in improving outcomes for patients.
  8. A small trial showed that a vaccine designed to provide broad protection against mosquito-borne diseases is safe and causes a strong immune response in healthy volunteers.
  9. A genomic analysis may help explain why some coronaviruses, like SARS-CoV-2, can be deadly, while others cause only mild illness.
  10. In patients with COVID-19, off-label use of a cancer drug reduced respiratory distress and over-reactive immune responses. The results were used to inform the design of a clinical trial.
  11. People with abnormal clusters of blood vessels in the brain called cavernous angiomas had differences in their gut bacteria. The findings could help lead to new diagnostic tests and treatments.
  12. Researchers created hair-growing skin from human stem cells and successfully grafted it to mice.
