Imagine someone remotely controlling your brain, forcing your body’s central processing organ to send messages to your muscles that you didn’t authorize. It’s an incredibly scary thought, but scientists have managed to accomplish this science fiction nightmare for real, albeit on a much small scale, and they were even able to prompt their test subject to run, freeze in place, or even completely lose control over their limbs. Thankfully, the research will be used for good rather than evil… for now.

The effort, led by physics professor Arnd Pralle, PhD, of the University at Buffalo College of Arts and Sciences, focused on a technique called “magneto-thermal stimulation.” It’s not exactly a simple process — it requires the implantation of specially built DNA strands and nanoparticles which attach to specific neurons — but once the minimally invasive procedure is over, the brain can be remotely controlled via an alternating magnetic field. When those magnetic inputs are applied, the particles heat up, causing the neurons to fire.

Ever wish you could heal yourself like a superhero? The government is making it happen. Sort of.

In a major step towards creating a tricorder, University of Illinois at Urbana-Champaign researchers have invented a device that allows smartphones to perform the kinds of lab-grade medical diagnostic tests that previously had to be done on large and expensive instruments.

The device, called a spectral transmission-reflectance-intensity (TRI)-Analyzer, plugs into a smartphone and is able to run tests on a patient’s blood, urine, or saliva as reliably as clinic-based instruments that cost thousands of dollars. The researchers say their TRI Analyzer costs only $550.

“Our TRI Analyzer is like the Swiss Army knife of biosensing,” said Prof. Brian Cunningham, the Donald Biggar Willett Professor of Engineering and director of the Micro + Nanotechnology Lab at Illinois.

Researchers at The Ohio State University Wexner Medical Center and Ohio State’s College of Engineering have developed a new technology, Tissue Nanotransfection (TNT), that can generate any cell type of interest for treatment within the patient’s own body. This technology may be used to repair injured tissue or restore function of aging tissue, including organs, blood vessels and nerve cells.

Stanford researchers accidentally discovered that iron nanoparticles invented for anemia treatment have another use: triggering the immune system’s ability to destroy tumor cells. Iron nanoparticles can activate the immune system to attack cancer cells, according to a study led by researchers at the Stanford University School of Medicine.

The nanoparticles, which are commercially available as the injectable iron supplement ferumoxytol, are approved by the Food and Drug Administration to treat iron deficiency anemia.

The mouse study found that ferumoxytol prompts immune cells called tumor-associated macrophages to destroy cancer cells, suggesting that the nanoparticles could complement existing cancer treatments. The discovery, described in a paper published online Sept. 26 in Nature Nanotechnology, was made by accident while testing whether the nanoparticles could serve as Trojan horses by sneaking chemotherapy into tumors in mice.
