    The Gators may not be in the Final Four this year, but the brainiacs on campus are still toiling away, regardless. Researchers at the institution (that'd be the University of Florida) have just stumbled onto a remarkable discovery that could eventually "starve cancer tumors and prevent side effects from a wide range of drugs." The magic find? A "lock-like molecule" that clasps or unclasps based on exposure to light. Sure, we've seen our fair share of newfangled drug delivery tools, but none that have been this noninvasive or simple to activate. In tests, gurus found that they could use visible or ultraviolet light to open or close a clasp, letting blood flow or creating a clot; in theory, this could one day be used to "prevent the formation of tiny blood vessels that feed tumors." Everything about this sounds just fantastic on the surface, but seriously, can you imagine how dead we'd be if the robots ever got ahold of this?[Via Physorg, image courtesy of NanotechNow]

  • Infrascanner: the handheld NIR hematoma detector

    As technology continues to make doctors' lives a bit easier (not to mention saving a few in the process), we've got yet another device that can detect a potentially fatal problem long before mere humans can figure it out. The Indian-based Infrascanner is a "handheld, non-invasive, near-infrared (NIR) based mobile imaging device used to detect brain hematoma at the site of injury" within the most important stage of pre-analysis. The device could also aid in the decision to proceed with "other tests such as head Computed Tomography (CT) scans" when not "facilitating surgical intervention decisions." While the methods behind the scanning are quite sophisticated, the unit uses diffused optical tomography to convert the light differential data seen in the local concentrations of hemoglobin into "interpretative scientific results." Potentially best of all, however, is just how close this thing is to actually hitting hospital wards, as it's simply missing the oh-so-coveted FDA stamp of approval before it can see commercial use.[Via MedGadget]
