Nobody wants to suffer physical pain if they don't have to, yet they also don't want to risk developing an addiction to pain-killing opioids. That's where a new drug-free implant comes in, as it reduces pain by cooling nerves.

Last year, scientists at Northwestern University announced a transient pacemaker that dissolves when no longer needed. They've now improved the device, and incorporated it into a linked suite of wearable sensors.

Researchers at Northwestern University in Illinois have demonstrated the world's smallest remote-controlled walking robot. These tiny machines can bend, twist, crawl, walk, turn and jump without hydraulics or electricity, using shape-memory alloys.

Scientists studying the mechanisms behind deafness have pinpointed a single gene they described as a type of master switch for cell differentiation, opening up exciting new possibilities around restoration of hearing.

Researchers have found sleeping in a moderately lit room can potentially harm a person’s cardiometabolic health. The study saw one night of sleep in a room with moderate light increased nighttime heart rates and spiked insulin resistance in the morning.

Researchers have uncovered a mechanism they say contributes to the age-related accumulation of iron in the brain. The study bolsters the hypothesis that reducing brain iron levels could combat neurodegenerative diseases such as Alzheimer’s.

A novel device developed at Northwestern can sort and multiply immune cells harvested from tumors with great efficiency, creating armies of personalized cancer-killing cells that have been deployed to induce dramatic tumor shrinkage in mice.

Researchers have developed a new nanotherapy to enhance the effectiveness of a type 1 diabetes treatment. The innovation packages immunosuppressive drugs into nanoparticles to reduce the likelihood of a body rejecting newly transplanted islet cells.

Healthcare workers often have to wear masks for up to 12 continuous hours, during which time they may become seriously exhausted. A new mask-mounted device is designed to help, by monitoring their vital signs and detecting leaks in the mask's seal.

Blind corners have long troubled drivers, but researchers have now developed a holographic camera technology that can peer around corners by reconstructing scattered light waves, quickly enough to spot fast-moving objects like cars or pedestrians.

Spinal cord injuries are among the most debilitating. In a new breakthrough study, Northwestern University researchers have developed a gel containing “dancing molecules” that allowed paralyzed mice to walk again four weeks after a single injection.

A dosing error during AstraZeneca’s COVID-19 vaccine trial unexpectedly led to better results, and now researchers have replicated those accidental findings to show some vaccines may be more effective if the first dose is much lower than the second.
