Muscle Enzyme Explains Weight Gain in Middle Age

Reblogged from The NIH Director’s Blog.

The struggle to maintain a healthy weight is a lifelong challenge for many of us. In fact, the average American packs on an extra 30 pounds from early adulthood to age 50. What’s responsible for this tendency toward middle-age spread? For most of us, too many calories and too little exercise definitely play a role. But now comes word that another reason may lie in a strong—and previously unknown—biochemical mechanism related to the normal aging process.

Little Fish in a Big Pond Reveal New Answers to Old Questions

Studying the neural control of behavior is a challenge. Researchers must consider an animal’s environment, past experiences, and motivations. Work in relatively simple organisms, for example the invertebrate C. elegans, has teased apart the neural circuitry of highly stereotyped behaviors, like foraging. But in mammals, very little is known, “and that’s surprising given just how important behaviors like this are,” said Dr. Eric Horstick, who studies the molecular mechanisms underlying animal behavior.

Studying ADHD from Genes to the Brain Connectome

My 8-year-old nephew Luke has a sixth-grade reading level, while still in the third grade. Yet, he often struggles to finish his chores. He carries a timer in his backpack to keep himself on task. His school provides Luke with special assistance, including extra time for tests and repeated, detailed instruction. The challenges arise because Luke, like his mother Rebecca, has attention-deficit/hyperactivity disorder (ADHD).

Isaac Fights to Inspire Others

Reblogged from The Children's Inn at NIH.

Isaac was born to fight. Arriving more than five weeks early by emergency C-section, it wasn’t just his way of coming into the world that made him different from his three brothers. While he initially looked healthy, his parents soon realized Isaac’s health was something he and the entire family would need to be fighting for every single day.

Cool Videos: Looking Inside Living Cells

ASCB Celldance 2016 — “Discovery Inside Living Cells in Multicellular Organisms” Roberto Weigert

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.

Find and Replace: DNA Editing Tool Shows Gene Therapy Promise

Reblogged from the NIH Director’s Blog.

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.

Simplifying HIV Treatment: A Surprising New Lead

Reblogged from the NIH Director's Blog.

CD4 cells in colon, SIV

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.

Four NIH IRP Researchers Elected to National Academy of Medicine

NIH National Academy of Medicine 2016

This year, members of the National Academy of Medicine elected four NIH Intramural researchers to their ranks, one of the highest honors in science. Learn a bit about each of their research and follow the links to their IRP profiles for more information.
