A major part of NIH’s mission is to support basic research that generates fundamental knowledge about the nature and behavior of living systems. Such knowledge serves as the foundation for the biomedical advances needed to protect and improve our health—and the health of generations to come.
Of course, it’s often hard to predict how this kind of basic research might benefit human populations, and the lag time between discovery and medical application (if that happens at all) can be quite long. Some might argue, therefore, that basic research is not a good use of funds, and all of NIH’s support should go to specific disease targets.
To counter that perception, I’m pleased to share some new findings that underscore the importance of publicly supported basic research. In an analysis of more than 28 million papers in the PubMed.gov database, researchers found NIH contributed to published research that was associated with every single one of the 210 new drugs approved by the Food and Drug Administration from 2010 through 2016 . More than 90 percent of that contributory research was basic—that is, related to the discovery of fundamental biological mechanisms, rather than actual development of the drugs themselves.

Happy Bike to Work Day! I really wish that I could take part in the festivities on the National Institutes of Health (NIH) campus in Bethesda, MD as I have in past years, but NIH-related travel is keeping me away from my trusty bike.
So, let me take a moment to commend all of the enthusiastic cyclists at NIH, along with everyone else out there who’s doing everything you can to get and stay physically fit. Here at NIH, we are particularly well situated to know the facts: taking charge of your health by participating in an exercise program and eating the right foods is among the most important investments you can make in your future.

If you’re concerned about your cardiovascular health, you’re probably familiar with “good” and “bad” cholesterol: high-density lipoprotein (HDL) and its evil counterpart, low-density lipoprotein (LDL). Too much LDL floating around in your blood causes problems by sticking to the artery walls, narrowing the passage and raising risk of a stroke or heart attack. Statins work to lower LDL. HDL, on the other hand, cruises through your arteries scavenging excess cholesterol and returning it to the liver, where it’s broken down.
One of the most debilitating, and heartbreaking, consequences of Alzheimer’s disease is the way it slowly robs people of their memories. Unfortunately, we don’t yet have a cure for Alzheimer’s, let alone a good understanding of exactly how this disease destroys memory skills. That’s why, in this first post in my series highlighting some of the awardees in NIH Common Fund’s High-Risk, High-Reward Research Program, I’m excited to introduce a young scientist who’s using some cool technology to tackle this formidable challenge: Christine Ann Denny.
A winner of a 2013 NIH Director’s Early Independence Awards (often called the “skip-the-postdoc” award), Denny has developed a technique to label the cells that encode individual memories in the brains of mice. That’s right: she tags the nerve cells that build these memories, the neurons, with a fluorescent molecule that glows. Continue reading →

Decoding the complete DNA genome in a single cell has been a major goal of technology developers. But the methods aren’t quite able to deal with that yet. So, for scientists to do this, they first need to make multiple copies of the DNA inside. Until now, the copying technology hasn’t been as accurate as scientists would like. If you think of the genome like a book, then our current copiers replicate certain chapters thousands of times, others just a few, and some not at all. As you can imagine, if you tried to read one of these copies, you’d be quite confused—and you certainly couldn’t rely on your reading for any medical purposes.
Now, NIH-funded researchers at the University of California, San Diego, have developed a new molecular technique that can accurately and uniformly copy the DNA inside a single cell . Using this technique, they’ve already made some surprising discoveries.
