NIH Women of the National Academy of Sciences, 1977-1998

Tuesday, March 21, 2017

What do Presidents Lincoln, Wilson, Eisenhower, and Bush have in common? They all supported the creation of a group of scientists, elected by their peers, to advise the government on matters of science and technology. In honor of Women’s History Month, we’re focusing on the women NIH scientists who’ve been elected to the National Academy of Sciences to serve their country with their expertise.

Remembrances: Alexis Shelokov (1919–2016)

Tuesday, March 7, 2017

Alexis Shelokov, who studied the polio virus at the NIH in the 1950s and was a powerful scientific force in what would become the famed NIAID Laboratory of Infectious Diseases in Building 7, died on December 12, 2016, in Dallas, Texas. He had a prolific scientific career that took him around the world.

Cool Videos: Looking Inside Living Cells

Monday, February 27, 2017

Roberto Weigert is a cell biologist who specializes in intravital microscopy (IVM), an extremely high-resolution imaging tool that traces its origins to the 19th century. What’s unique about IVM is its phenomenal resolution can be used in living animals, allowing researchers to watch biological processes unfold in organs under real physiological conditions and in real time.

NIH Heart Surgery Artifacts – Aortic Valve Bypass Assembly

Tuesday, February 7, 2017

Sometimes as a museum curator, I come across a box in the collection with a vague marking and full of bits and pieces of … something. One of the coolest things is finding out what that something was and who created it. This photo shows pieces from the NIH lab of Dr. Stanley Sarnoff, dating from 1954-1962.

Find and Replace: DNA Editing Tool Shows Gene Therapy Promise

Thursday, January 26, 2017

This image represents an infection-fighting cell called a neutrophil. In this artist’s rendering, the DNA of a cell is being “edited” with a pen-like tool to help restore its ability to fight bacterial invaders.

For gene therapy research, the perennial challenge has been devising a reliable way to insert safely a working copy of a gene into relevant cells that can take over for a faulty one. But with the recent discovery of powerful gene editing tools, the landscape of opportunity is starting to change. Instead of threading the needle through the cell membrane with a bulky gene, researchers are starting to design ways to apply these tools in the nucleus—to edit out the disease-causing error in a gene and allow it to work correctly.

Biomedical Innovation at NIH — Then and Now

Tuesday, January 10, 2017

Display titled "Then and Now" that shows progressive stages of various biomedical technologies

To paraphrase President Obama from his guest editorial in the November issue of Wired magazine, there’s never been a better time to be alive. One NIH institute leading us into the future is the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which supports avant-garde investigators at the nexus of engineering and the physical and life sciences with innovations that improve global health.

Developing Methods to Study the Brain's Visual System in Action

Friday, January 6, 2017

How does the brain know that what we’re looking at is standing still or moving? Dr. Robert H. Wurtz developed methods for studying the visual system, a technique now widely used for the study of higher brain functions, to find the answer to that question.

NIH researchers identify heritable brain connections linked to ADHD

In a new study of families affected by Attention Deficit Hyperactivity Disorder (ADHD), National Institutes of Health (NIH) Intramural researchers have identified different connections in the brain that children may inherit from their parents and are linked to the disorder.

Simplifying HIV Treatment: A Surprising New Lead

Tuesday, November 15, 2016

The surprising results of an animal study are raising hopes for a far simpler treatment regimen for people infected with the AIDS-causing human immunodeficiency virus (HIV). Currently, HIV-infected individuals can live a near normal life span if, every day, they take a complex combination of drugs called antiretroviral therapy (ART). The bad news is if they stop ART, the small amounts of HIV that still lurk in their bodies can bounce back and infect key immune cells, called CD4 T cells, resulting in life-threatening suppression of their immune systems.

Challenges to Training Artificial Intelligence with Medical Imaging Data

Tuesday, November 1, 2016

If you were going to train an artificial intelligence (AI) system to understand and accurately diagnose medical images, what kind of information do you think would be most effective: lots of general image data, or small amounts of specific data?
