Remote-controlled cyborg moth ‘biobots’ to monitor emergency-response operations | KurzweilAI

North Carolina State University researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals that moths use to control those muscles. The goal: remotely-controlled moths, or “biobots,” for use in emergency response, such as search and rescue operations.

“The idea would be to attach sensors to moths … to create a flexible, aerial sensor network that can identify survivors or public health hazards in the wake of a disaster,” said Alper Bozkurt, PhD, an assistant professor of electrical and computer engineering at NC State and co-author of a JOVE paper on the work.

Bozkurt, with Amit Lal, PhD, of Cornell University, previously developed a method for attaching electrodes to a moth during its pupal stage, when the caterpillar is in a cocoon undergoing metamorphosis. Now, Bozkurt’s research team wants to find out precisely how a moth coordinates its muscles during flight.

University at Buffalo researchers are developing a new imaging technique using nanoparticles suspended in liquid to form “nanojuice” that patients would drink to help diagnose irritable bowel syndrome, celiac disease, Crohn’s disease and other gastrointestinal illnesses.

Doctors would strike the nanoparticles, once they reach the small intestine, with a harmless laser light, providing an unparalleled, non-invasive, real-time view of the organ.

Described July 6 in the journal Nature Nanotechnology, the advancement could help doctors better identify, understand, and treat gastrointestinal ailments.

Clear material on windows harvests solar energy - A new type of “transparent” solar concentrator can be used on windows or mobile devices to harvest solar energy without obscuring the view. Past efforts to create similar materials have been disappointing, with inefficient energy production or highly colored materials. “No one wants to sit behind colored glass,” says Richard Lunt, an assistant professor of chemical engineering and materials science at Michigan State University. “It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent.” The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. “We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared,” he says. The “glowing” infrared light is guided to the edge of the plastic, where it is converted to electricity by thin strips of photovoltaic solar cells. “Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye,” Lunt says.

Jessica Hagy beautifully illustrates them here. - If you’re automatically sure that you know what reality is, and you are operating on your default setting, then you, like me, probably won’t consider possibilities that aren’t annoying and miserable … But if you really learn how to pay attention, then you will know there are other options. It will actually be within your power to experience a crowded, hot, slow, consumer-hell type situation as not only meaningful, but sacred, on fire with the same force that made the stars: love, fellowship, the mystical oneness of all things deep down.

First US patient receives cluster headache-stopping facial implant

See on Scoop.it - The future of medicine and health

Although there’s presently no cure for cluster headaches, a new neurostimulator is claimed to help control them. While they may not be quite as well-known as migraines, cluster headaches are even more painful, and can occur several times a day. There’s presently no cure, although a new “neurostimulator” is claimed to help control them. A US clinical trial of the device has just begun, with a test subject recently having had one implanted beneath his cheekbone.

Developed by San Francisco-based Autonomic Technologies Inc (ATI), the “almond-sized” device was inserted through a 2-cm (0.8-in) incision in the recipient’s gum, at The Ohio State University Wexner Medical Center.

Anchored to the skull under the cheekbone, on the side of the face affected by the headaches, the implant works by stimulating the sphenopalatine ganglion (SPG). This is a nerve bundle located behind the nose, and it’s associated with the transmission of the headache pain. Past approaches have included permanently cutting or chemically burning the SPG.

When a patient feels a cluster headache coming on, they place a separate handheld controller against their cheek. It wirelessly activates the neurostimulator, which in turn blocks the pain signals sent via the SPG. The controller is preprogrammed by the patient’s physician, to provide a length and level of stimulation that’s appropriate to their particular condition.
