How Oxytocin Makes A Mom: Hormone Teaches Maternal Brain To Respond To Offspring’s Needs

Researchers have discovered the mechanism by which oxytocin helps mothers be responsive to their offsprings' needs. The research was done in an animal model, but may have implications for humans.

Neuroscientists at NYU Langone Medical Center have discovered how the powerful brain hormone oxytocin acts on individual brain cells to prompt specific social behaviors — findings that could lead to a better understanding of how oxytocin and other hormones could be used to treat behavioral problems resulting from disease or trauma to the brain. The […]

Pain-Free Blood Tests

This prototype device is being developed into a fool-proof, almost painless way to draw blood samples by Tasso, formed by students of the University of Wisconsin-Madison.

A company with deep roots at the University of Wisconsin-Madison wants to make blood sampling less painful and more convenient. Tasso Inc. is perfecting a device the size of a pingpong ball that extracts a small sample while held against the skin for two minutes. During this time, a slight vacuum in the device enables […]

Cracking Your Knuckles: What Really Happens Inside Your Joints?

Static images revealed normal metacarpophalangeal joints with the expected lack of any gaseous cavity prior to joint distraction [Figure 2]. Following the cracking event, static imaging with the addition of MCP distraction yielded a dark intra-articular void [Figure 2].)

“Pull my finger,” a phrase embraced by school-aged kids and embarrassing uncles the world over, is now being used to settle a decades-long debate about what happens when you crack your knuckles. In a new study published in PLOS ONE, an international team of researchers led by the University of Alberta used MRI video to […]

Shape-Shifting Molecule Tricks Viruses Into Mutating Themselves To Death

Andre Tokmakoff and Sam Peng collaborated with associates at the University of Chicago and the Massachusetts Institute of Technology used a range of chemical tools to better understand the molecular action of an anti-viral drug.

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus’s genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments. Viruses can mutate rapidly […]

New Method Increases Accuracy Of Ovarian Cancer Prognosis And Diagnosis

Nearly anyone touched by ovarian cancer will tell you: it’s devastating. It’s bad enough that cancer in almost 80% of patients reaches advanced stages before diagnosis, and that most patients are expected to die within five years. But just as painfully, roughly one quarter of women diagnosed have no warning that they are resistant to […]
