Tinnitus, the ringing, buzzing or hissing sound of silence, varies from slightly annoying in some to utterly debilitating in others. Up to 15% of adults in the United States have tinnitus, where nearly 40% of sufferers have the condition chronically and actively seek relief.

A recent study from researchers at the University of Michigan’s Kresge Hearing Research Institute suggests relief may be possible.

Susan Shore, Ph.D., Professor Emerita in Michigan Medicine’s Department of Otolaryngology and U-M’s Departments of Physiology and Biomedical Engineering, led research on how the brain processes bi-sensory information, and how these processes can be harnessed for personalized stimulation to treat tinnitus.

Her team’s findings were published in JAMA Network Open.

In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research.

Summary points

The human nucleus is metabolically active, according to the findings of a new study in Molecular Systems Biology by researchers at the CRG in Barcelona and CeMM/Medical University of Vienna,

In a state of crisis, such as widespread DNA damage, the nucleus protects itself by appropriates mitochondrial machinery to carry out urgent repairs that threaten the genome’s integrity

The findings represent a paradigm shift because the nucleus has been historically considered to be metabolically inert, importing all its needs through supply chains in the cytoplasm

Cancer hijacks cellular metabolism...

While indigestible video capsule endoscopes have been around for many years, the capsules have been limited by the fact that they could not be controlled by physicians. They moved passively, driven only by gravity and the natural movement of the body. Now, according to a first-of-its-kind research study at George Washington University, physicians can remotely drive a miniature video capsule to all regions of the stomach to visualize and photograph potential problem areas. The new technology uses an external magnet and hand-held video game style joysticks to move the capsule in three-dimensions in the stomach. This new technology comes closer to the capabilities of a traditional tube-based endoscopy.

“A traditional endoscopy is an invasive procedure for patients, not to mention it i...

Recent advancements in the field of electronics have enabled the creation of smaller and increasingly sophisticated devices, including wearable technologies, biosensors, medical implants, and soft robots. Most of these technologies are based on stretchy materials with electronic properties.

While material scientists have already introduced a wide range of flexible materials that could be used to create electronics, many of these materials are fragile and can be easily damaged...
