Spinal cord injuries are much more common than one might expect. As a result, finding a cure would be life changing for millions of Americans. Dr. Michael E. Selzer has been studying this topic for nearly 40 years. He provides insight on how a cure could be developed by looking at an animal capable of repairing its own spinal cord. The sea lamprey, a species of deep sea fish, is capable of regenerating a severed or broken spine. By looking at its genome, scientists hope to one day discover a method to apply the lamprey’s healing capabilities to humans
In Brief Opioids are addictive drugs doctors prescribe for patients enduring significant pain. Consistent exercise can potentially help people who are addicted to opioids in weaning their use. Some rat studies show frequent exercise decreases the need for large opioid doses, but other studies show conflicting results.

Did you know dolphins can play an important role in helping us maintain public health? Universally loved for their intelligence and friendliness, these sea creatures have also become a subject of interest in the research community. Dolphins can help scientists better understand the spread of diseases like measles, potentially develop better treatments for diabetes, and even detect ocean toxins! Check out the story for more details.
Human behaviors can be difficult to understand. Overly aggressive behaviors, extreme anxiety, and depression may be linked to cognitive issues that require intervention. Studying psychopathic traits in chimpanzees can potentially help us better assess mental health concerns. Read more to learn how this animal model plays an important role in research!
Can humans someday regenerate like the superhero Deadpool? Studies on tissue restoration in African spiny mice reveal the potential genetic origin for this extraordinary occurrence. With continued research in wound healing, the unappealing scars humans are subjected to may someday be replaced by rejuvenated skin. Check out the story for more details!
