After a long search, you’ve found your Person of Interest—and he’s making it abundantly clear that, while you were hoping for a civilized chat back at the station, he makes it clear he doesn’t like the ambiance there. You don’t want to shoot, you’re too far away to use your Taser, and it’s not like you walk around with a spare tear gas canister hanging from your belt. What’s a law enforcement officer to do?
That’s where the StunRay comes in. A non-lethal, spotlight-like weapon, this new device is designed to disorient its targets with by overloading their neural circuitry with a burst of high-intensity light. Genesis Illumination, which makes the device, patented it in January. (You can see the device in action in this video put out by Genesis.)
By bringing the field of photovoltaics into medicine, researchers hope to create a far more precise method of drug delivery for fighting cancer. That’s right: this cancer cure involves tiny photovoltaic particles like the kind used in solar cells.
One of the major drawbacks of chemotherapy is that it damages far more of the body than just the malignant tumors it’s used to fight. In order to target just the cancerous areas, and not hit everything on the way there, researchers from the University of Texas in El Paso created a tiny solar cell. They attached model drugs to each side of the cell, one of which was positively charged, the other negatively. Once the tiny solar devices are in the body, doctors would blast the tumor with an infrared laser, causing the pholtovoltaic particles to release the drugs.
