’Rewiring’ metabolism in insulin-producing cells may aid Type 2 diabetes treatment
Researchers have discovered a previously unknown way that pancreatic cells decide how much insulin to secrete. It could provide a promising new target to develop drugs for boosting insulin production in people with Type 2 diabetes. In a pair of papers recently published in Cell Metabolism, scientists from the University of Wisconsin-Madison and their colleagues point to an overlooked enzyme known as pyruvate kinase as the primary way pancreatic beta cells sense sugar levels and release the appropriate amount of insulin.

Songbirds sing - like humans flock - for opioid reward
What do songbirds and humans have in common? We crave social interaction, and the chemical rewards that flood our brain when we get it. In a study recently published in Scientific Reports, University of Wisconsin-Madison researchers led by Lauren Riters, professor of integrative biology, found that when songbirds sing during non-mating seasons, it's because singing releases an opioid naturally produced in their brain -that's right, a compound with the same biological makeup of the highly addictive painkillers.

Astronomers model, determine how disk galaxies evolve so smoothly
Using advanced computer simulations, astrophysicists are learning how galaxies evolve their characteristic structure - super-bright centers fading away to dark edges. Researchers from the University of Wisconsin-Madison, Iowa State University and IBM Research have discovered that massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating a smooth, exponential fade in the brightness of many galaxy disks.

Stem cells can repair Parkinson’s-damaged circuits in mouse brains
The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson's. Stem cells, which are endlessly adaptable, have offered the promise of better neural repair. But the brain's precisely tuned complexity has stymied the development of clinical treatments.

Patients taking opioids produce antibodies that may hinder anti-opioid vaccine
University of Wisconsin-Madison scientists have discovered that a majority of people they tested who were taking opioid painkillers for chronic back pain produced antibodies against the drugs that may contribute to some of the negative side effects of long-term opioid use. The findings add to a growing understanding of how the immune system can recognize drugs and influence their effects in the body, which may ultimately support the production and delivery of a vaccine that reduces the harm of opioid abuse.
