tDCS has come a long way from Giovanni Aldini's 1802 pioneering treatment of Luigi Lanzari...

Transcranial direct current stimulation (tDCS) has become a widely used technique for reaching into a person's brain and altering the way in which it functions. Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have just published the results of a new study in the Journal of Neuroscience in which they found that tDCS stimulation of the mediofrontal cortex for a period of minutes can change one's ability to recognize and learn from error for a period of several hours.  Read More

The ATHENA organ project combines heart, liver, kidney and lung features in a toxicity tes...

A five-year, US$19 million multi-institutional effort is working on developing a "desktop human" that could reduce the need for animal testing in the development of new drugs. The "homo minitus" is a drug and toxicity analysis system that would comprise four human organ constructs interconnected to mimic the response of human organs. The project has now reported success in the development of its first organ construct, a human liver construct that responds to exposure to a toxic chemical much like a real liver.  Read More

The capsule being tested using silicone gel

Researchers at Nashville's Vanderbilt University have developed a wireless capsule that can restore a sense of touch for surgeons. Keyhole surgeries or other minimally invasive procedures could benefit greatly from this new technology, as the capsule provides haptic feedback to help doctors maneuver and make important conclusions during surgery.  Read More

A newly developed silicon supercapacitor could allow for the seamless integration of energ...

A team of researchers at the Vanderbilt University in Nashville, Tennessee has designed a supercapacitor made primarily of silicon that has shown much improved power density over its commercially available alternatives. The advance could allow for interesting integration of battery technology in everyday electronics, from solar cells to smartphones.  Read More

The active cannula goes to work on a simulated blood clot

Intracerebral hemorrhaging is what occurs when a blood vessel in the brain bursts, and the blood which subsequently leaks out of that vessel forms a clot that places pressure on the surrounding brain tissue. It’s not that uncommon of an occurrence, it’s difficult to treat, and is fatal in about 40 percent of cases. Help may be on the way, however. A team from Nashville’s Vanderbilt University has created a robotic device that is designed to remove those clots, in a safe and minimally-invasive fashion.  Read More

A new smartphone-based system is able to triangulate the approximate whereabouts of sniper...

If you were out on the street and suddenly heard sniper fire, you would no doubt react by ducking for cover. The problem is, it’s not always obvious which direction the sound is coming from – crouching behind a certain object might shield you from the bullets, but it also might display you nicely in the shooter’s crosshairs. That’s why a team of computer engineers from Nashville’s Vanderbilt University have developed a smartphone-based system, that determines the location at which the gunshots originated.  Read More

Test subject Brian Shaffer uses the prototype exoskeleton

For people who are unable to walk under their own power, exoskeletons offer what is perhaps the next-best thing. Essentially “wearable robots,” the devices not only let their users stand, but they also move their legs for them, allowing them to walk. While groups such as Berkeley Bionics, NASA, Rex Bionics, and ReWalk are all working on systems, Nashville’s Vanderbilt University has just announced the development of its own exoskeleton. It is claimed to offer some important advantages over its competitors.  Read More

Adding plant proteins greatly enhances silicon solar cells (Image: Julie Turner/Vanderbilt...

Popeye gets his strength from downing a can of spinach and what works for him also works for solar panels. Researchers at Vanderbilt University led by David Cliffel and Kane Jennings have come up with a way to dope silicon with a protein found in spinach to create a more efficient "biohybrid" solar cell that produces substantially more electrical current than previous efforts and may one day lead to cheaper, more efficient solar panels.  Read More

The SUAVe system allows an unmanned aerial vehicle to create detailed aerial maps of arche...

If you were in Peru right now, at the long-abandoned Inca village of Mawchu, you might see something very modern flying over it – a Skate unmanned aerial vehicle. The aircraft is the key part of a system designed by a team from Nashville’s Vanderbilt University. Once perfected, it should be able to accomplish in 10 to 15 minutes what would take an archeological team two to three field seasons to complete.  Read More

Scientists have determined that graphene could be put to use as the world's thinnest anti-...

It seems like the uses for graphene just won’t stop coming. The ultra-strong sheet material, made from bonded carbon atoms, has so far shown promise for use in transistors, computer chips, DNA sequencing, and batteries ... just to name a few possibilities. Now, scientists have discovered that it can also be used as a very effective anti-corrosion coating – and at just one atom in thickness, it’s thinner than any of the alternatives.  Read More
