NIH Health Research

A weekly summary of research developments and discoveries at the National Institutes of Health (NIH)
  1. Researchers used machine learning to analyze brain images and identify people with suicidal thoughts. The approach could be used to assess suicide risk and monitor response to treatments.
  2. A study in lab animals showed that communication between two brain regions may be needed for the formation of long-term memories.
  3. Researchers designed a highly specific RNA editing system based on the CRISPR/Cas gene editing technology. The study suggests a potential alternative to gene therapy.
  4. The structure of a brain receptor for dopamine guided the design of a compound that activates it specifically. The approach could lead to psychiatric drugs with fewer side effects.
  5. An injectable hydrogel grew intestine-like tissues and accelerated wound healing in the intestines of mice. The findings suggest new treatments for diseases such as inflammatory bowel disease.
  6. Scientists identified brain activity that influences how a mouse responds when it meets an intruder mouse, a response that was once thought to be purely instinctive.
  7. A new study suggests that some widely used acid reflux (heartburn) medications may worsen chronic liver disease.
  8. Mosquitoes genetically modified to resist the parasite that causes malaria mated with wild mosquitoes and transferred the resistance to offspring in laboratory experiments.
  9. In mouse studies, scientists found a mechanism that may explain why low levels of potassium in the diet have been linked to high blood pressure, heart disease, and stroke in people.
  10. Two test vaccines for Ebola were safe and induced lasting immune responses in a study with 1,500 adults in Liberia. The findings are an important step in development of a vaccine.
  11. Researchers discovered that our brains may drain waste out through lymphatic vessels, the body’s sewer system. They could be a pipeline between the brain and the immune system.
  12. Experiments in mice revealed mechanisms that may help explain why bones become weaker in older adults.
