  1. Liquid Biopsy Offers Less-Invasive Diagnosis Of Colorectal Cancer

    Researchers in Singapore have developed a new liquid biopsy approach. Designed to specifically detect colorectal cancer in its early stages, the new diagnostic technique promises to enable a personalized approach to cancer treatment without invasive tissue biopsies.

  2. Flower-Like Magnetic Nanoparticles Could Improve Cancer Treatment

    Researchers at the Dartmouth Center of Nanotechnology Excellence have developed flower-shaped magnetic nanoparticles that are highly sensitive to magnetic fields. This increased sensitivity may enable hyperthermic treatment of deeper, harder-to-reach tumors.

  3. Using Magnets To Steer Instruments In Single-Incision Surgery

    Using a novel application of magnetic force, researchers from Vanderbilt University have developed minimally invasive surgical instruments that could be more effective and easier to use than current technology. By passing magnetic fields through tissue, the instruments can be operated without being physically manipulated, which could reduce the incisions required and improve function.

  4. Researchers Optically Stimulate The Brain To Control Pain

    By optically stimulating the anterior cingulate cortex in mice, researchers at the University of Texas at Arlington (UT Arlington) were recently able to dampen the animals’ sense of pain.

  5. Paper-Based Test Diagnoses Ebola, Other Fevers In 10 Minutes

    Using multicolored silver nanoparticles, a team from the Massachusetts Institute of Technology (MIT) recently developed a diagnostic device that can simultaneously test for several hemorrhagic fevers.

  6. Bionic Reconstruction Enables 3 Men To Replace Nonfunctioning Hands

    Three Austrian men were the first to undergo a new “bionic reconstruction” procedure, which enabled them to use mind-controlled prosthetic hands. The patients all suffered from brachial plexus injury, which has been called an “inner neurological amputation” because it completely separates the hand from its owner’s control.

  7. Could 3D-Printed Guides Enable Personalized Nerve Regeneration Therapy?

    Using 3D printed nerve guidance conduits, University of Sheffield researchers have succeeded in helping nerves to repair themselves in vivo.

  8. FDA Clears Medtronic’s VenaSeal Closure System For Varicose Veins

    A new approach to permanently seal superficial varicose veins has recently been approved by the FDA. Using cyanoacrylate adhesive, Medtronic’s Venaseal closure system is a minimally invasive approach that can be performed in an office or outpatient setting.

  9. MIT Researchers Develop Self-Healing, Injectable Nanogel

    To eliminate the need for open surgical implantation, researchers from the Massachusetts Institute of Technology (MIT) have developed a new injectable nanogel.

  10. Pancreas-In-A-Capsule Enters Clinical Trials

    One of the few devices in the United States based on embryonic stem cell technology has recently moved into clinical trials. Viacyte, a startup company in San Diego, has used its tissue engineered pancreatic replacement technology to reverse diabetes in animals, an advance that is now being tested in human clinical trials. A successful trial could lead to relief for many millions of people suffering from diabetes.
