Shear-Thinning Gel Makes for Easier Polyp Removals

When removing pre-cancerous polyps from the colon, physicians typically inject saline into the tissue below the polyps to raise them and make them easier to access. However, saline drains away quickly, requiring precise timing and repeat injections, among other difficulties. Now, scientists at MIT have developed an injectable material that can be u (Read more...)

Wireless Brain Implant Controls Mice Using Drugs and Light

Optogenetics is a quickly evolving field that allows scientists to activate specific neurons using bursts of light. The technique may help to uncover the basis of neurological diseases and how to tame them. Using optogenetics to assess how different drugs affect the central nervous system may offer a powerful new scientific tool. To that end, [&hel (Read more...)

New Device Supports Dialysis Fistulas

Vascular Graft Solutions, a company based in Tel Aviv, Israel, has won the European CE Mark for its FRAME FR device for repair and support of high flow and aneurysmal arteriovenous fistulas. These are created in hemodialysis patients to allow for more blood to flow through a vein and give easy access for dialysis needles. […]

Biomaterial Tricks Immune System to Grow New Blood Vessels

Researchers from Harvard’s Wyss Institute have developed a new biomaterial that can activate T cells to promote vascularization of ischemic tissues. Their work demonstrates that the biomaterial results in local blood vessel development, increased perfusion, and new muscle growth after ischemia. Various compounds have been tested to try to imp (Read more...)

Magnetically Controlled Soft Robots to Operate on Human Body

Although a myriad of robots is already used in a variety of industries, including medicine, they’re almost exclusively rigid devices using conventional mechanics. To best work with the pliability of the human body, it may be advantageous for medical robots to be soft and not include gears, motors, and metal cables. Researchers at North Caroli (Read more...)

Device Speeds Cervical Cancer Screening

When screening for cervical cancer, immunofluorescence staining is used to identify the presence of proteins that are biomarkers for the disease. It is a slow and meticulous process that requires lab technicians to prepare individual cells for analysis. Even then, since not all cells show the same disease characteristics, the rate of false negative (Read more...)
