Origins of Pain

painful shoulder

Researchers have identified the nerve-signaling pathway behind the deep, sustained pain that sets in following injury.

Researchers identify pathway that drives sustained pain following injury. Withdrawing one’s hand to avoid injury and soothing the pain of that injury are two distinct evolutionary responses, but their molecular origins and signaling pathways have eluded scientists thus far.

Now research led by investigators at Harvard Medical School, published Dec. 10 in Nature, identifies the nerve-signaling pathway behind the deep, sustained pain that sets in immediately following injury. The findings also shed light on the different pathways that drive reflexive withdrawal to avoid injury and the subsequent pain-coping responses.

Clinical observations of patients with neurolog...

Peeling off Slimy Biofilms like Old Stickers

Researchers at Princeton have found a new method to remove biofilms, bacterial mats that can cause infections and foul industrial equipment. The method, using peeling, contrasts with scraping or mechanically dislodging biofilms, which can leave patches that regrow and recontaminate.

Slimy, hard-to-clean bacterial mats called biofilms cause problems ranging from medical infections to clogged drains and fouled industrial equipment. Now, researchers at Princeton have found a way to cleanly and completely peel off these notorious sludges.

By looking at the films from a mechanical engineering perspective, as well as a biological one, the researchers showed that water penetrating the junction between biofilms and surfaces, coupled with gentle peeling...

Ingestible Capsule can be controlled Wirelessly

Electronic pill can relay diagnostic information or release drugs in response to smartphone commands. Researchers at MIT, Draper, and Brigham and Women’s Hospital have designed an ingestible capsule that can be controlled using Bluetooth wireless technology. The capsule, which can be customized to deliver drugs, sense environmental conditions, or both, can reside in the stomach for at least a month, transmitting information and responding to instructions from a user’s smartphone.

The capsules, manufactured using 3D-printing technology, could be deployed to deliver drugs to treat a variety of diseases, partic...

Fighting Obesity: Could it be as plain as Dirt?

UniSA research digs up the fat-fighting power of clays. It costs the global economy an estimated US$2 trillion annually and has been dubbed a modern day health epidemic, but new research from the University of South Australia has unearthed a possible cure for obesity – and it is as plain as dirt!

Investigating how clay materials can improve drug delivery, UniSA researcher and PhD candidate, Tahnee Dening serendipitously discovered that the clay materials she was using had a unique ability to “soak up” fat droplets in the gut.

Dening says this accidental discovery could potentially be a cure for obesity...
