NIH Health Research

A weekly summary of research developments and discoveries at the National Institutes of Health (NIH)
  1. Although diet quality improved modestly for American children and adolescents from 1999 to 2016, more than half still had poor quality diets.
  2. For patients with heart disease, invasive procedures showed similar reductions in the risk of heart attack and death to medication and lifestyle changes alone.
  3. A new technique to engrave 3D-printed scaffolds could be used to boost the repair of complex tissues with different types of cells, such as bone and cartilage.
  4. Adults who took 8,000 or more steps a day had a reduced risk of death over the following decade than those who only walked 4,000 steps a day.
  5. Researchers found that drugs like Ritalin may work as a study aid by shifting attention, through the brain chemical dopamine, from the challenges of undertaking a difficult mental task to its rewards.
  6. Using advanced imaging techniques, researchers revealed how different bacteria live together in communities on the human tongue.
  7. Scientists found that SARS-CoV-2, the virus that causes COVID-19, can be detected in aerosols for up to three hours and on plastic and stainless steel surfaces for up to three days.
  8. Mice engineered to lack a protein that anchors mitochondria in injured nerve cells showed regrowth of those cells after a spinal cord injury.
  9. Researchers discovered how distinct liquid droplets within cells help build the skin’s outer layer. The study may lead to a better understanding of conditions like atopic dermatitis and psoriasis.
  10. Adding MRI-targeted biopsies to the traditional prostate biopsy created a more accurate diagnosis and prediction of the course of prostate cancer.
  11. Artificial intelligence-based analysis of CT scans predicted people’s risk of heart disease more accurately than current methods.
  12. Researchers found that the distinct firing patterns of individual neurons that the brain uses when forming memories are replayed when remembering the experience.
