Research Symposium Celebrates Graduate Student Science

Event Spotlights Students Completing Their Ph.D. Research in IRP Labs

The NIH provides an extraordinarily rich environment for learning and honing the skills needed to pursue a scientific career. It’s no wonder, then, that Ph.D. students from institutions all across the United States and the rest of the world come here to conduct their dissertation research under the mentorship of the IRP’s many renowned investigators.

Nearly 150 of those students presented the fruits of their scientific work at the NIH’s 16th annual Graduate Student Research Symposium on Thursday, February 20. The insights they have produced on topics from cancer to autoimmune disease to environmental contaminants were supremely impressive and will likely contribute to important improvements in medical care in the future. For anyone who missed this exciting event, read on to learn about a few of the many research projects that were on display.

Neuron-Killing Protein Exploits a Vulnerability in Mitochondrial Armor

Study Shows How Molecular Trespasser Gains Entry into Cells’ Energy Producers

As a fan of the long-running animated sitcom The Simpsons, I’ve witnessed the bumbling Homer Simpson cause several near-meltdowns at the nuclear power plant where he works. Serious problems can arise at such facilities when the wrong person gains access to them, and the same applies to the energy-producing mitochondria that power our cells. A new IRP study has revealed how a protein known to harm neurons gains entry into mitochondria in order to wreak cell-killing havoc.

Reining in Runaway Enzyme Halts Neuronal Destruction

Mouse Study Supports Potential Treatment Approach for Numerous Neurological Diseases

Winter is fast approaching, bringing with it both picturesque snow flurries and raging blizzards. It's a good reminder that something that is desirable in moderate amounts can be downright dangerous in large quantities, and the systems that keep our cells healthy are no different. IRP researchers recently found a novel way to tamp down a runaway cellular process that can kill neurons, findings that may one day lead to new treatments for several debilitating neurological conditions.

Postbac Poster Day Highlights Budding Researchers

On Wednesday, May 2, hundreds of researchers gathered at NIH’s Natcher Conference Center to show off their recent discoveries. But unlike a typical scientific conference, the letters “M.D.” and “Ph.D.” were noticeably absent from these scientists’ credentials. Instead, the event — NIH’s annual Postbac Poster Day — celebrated the accomplishments of individuals participating in the NIH Postbaccalaureate Intramural Research Training Award (IRTA) Program.

Neuronal Trees in Holiday Colors

These may remind you of trees on a winter day, but they are brain neurons grown in a special chamber that separates axons from dendrites.
