Neurologists who work to unlock the secrets of brain activity encounter what one might call the Las Vegas effect: “What happens in the brain, stays in the brain.” The skull and dura mater are efficient insulators, keeping high-frequency electrical activity from leaving the brain. And between the blood-brain barrier and the brain’s aggressive immune system, [...]

In the world of medical imaging, no single technology provides all the answers for the critical procedure of breast cancer biopsy. Magnetic resonance imaging (MRI), for example, produces clear, highly revealing images of potential breast cancer lesions, but lacks practicality in obtaining a biopsy sample. Ultrasound imaging, on the other hand, is less revealing than [...]

Bioactive coatings promote cell growth For people who suffer excruciating back pain due to injury or disc degeneration, relief often comes in the form of spinal fusion and disc replacement. Metallic implants are the current standard, and while these devices mechanically fix tissue or replace vertebrae, they don’t heal the problem. Responding to patients’ need [...]

Founders of UW-Madison spin-off company NeuWave Medical are improving microwave ablation, a minimally invasive procedure that could expand the number of treatment options for people with certain types of cancer. To perform microwave ablation, radiologists use ultrasound imaging or computed tomography to guide a thin antenna into the body. The antenna radiates enough energy to [...]

With their flowing, tentacle-like arms, Associate Professor Shaoqin (Sarah) Gong’s polymer nanoparticles can locate, infiltrate and annihilate cancerous tumors—currently, in mice. Someday,  tiny drug-delivery tools could be an alternative to chemotherapy as a targeted method for cancer drug delivery. Because it often grows quickly, tumor tissue is “sloppy” tissue, with leaky vasculature. “Nanoparticles are unique [...]
