NIH Health Research

A weekly summary of research developments and discoveries at the National Institutes of Health (NIH)
  1. People who were inactive as teens and young adults but increased physical activity in middle age saw the same reduced risk of death as those who stayed active from adolescence onward.
  2. Teaching parents ways to respond to their child’s anxiety may reduce symptoms as well as the standard therapy treatment for childhood anxiety.
  3. Researchers identified drugs to restore heart muscle function in rodents with heart failure. The findings may help pave the way for a similar approach in people.
  4. People with consistent sleep deprivation gained weight and experienced a loss of insulin sensitivity. Weekend “recovery” sleep only seemed to make things worse.
  5. Feeding mice cycles of a certain low-calorie diet improved signs of inflammatory bowel disease. Feeding people a similar diet seemed to reduce overall inflammation.
  6. Researchers developed a resistance-sensitive injection device that could help reduce errors when targeting tissues that are difficult to reach using traditional syringes.
  7. Women in lower-income countries who received nutritional supplements before or early in pregnancy were more likely to give birth to healthy-sized babies.
  8. Researchers found that sleep disruption activates a molecule that triggers inflammation and leads to fatty buildup in mouse arteries.
  9. Scientists created novel DNA structures from four synthetic and four natural building blocks.
  10. In children with recurrent tonsillitis, the bacteria that cause the disease trick immune cells into destroying each other instead of remembering the bacteria.
  11. Researchers found that blocking DNA repair made gliomas, a type of deadly brain tumor, more responsive to radiation therapy in mice. The study suggests possible treatment strategies.
  12. Engineers designed a sensor-containing device that can quickly inflate with fluid in the stomach and then shrink on demand. The device could make it possible to monitor conditions in the stomach and deliver slow-release drugs.
