DARPA Plans Bioelectronic ‘Travel Adapter’ to Cure Diarrhea, Jet Lag
DARPA's ADvanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER) program

The US Defence Advance Research Projects Agency (DARPA) has initiated a new project to develop a ‘travel adapter for the human body, an implantable or ingestible bio-electronic carrier to cure US soldiers from diarrhea and jet lag.

Called the ADvanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER) program, the integrated system will be designed to entrain the sleep cycle – either to a new time zone or back to a normal sleep pattern after night missions – and eliminate bacteria that cause traveler’s diarrhea after ingestion of contaminated food and water.

ADAPTER will provide a transient, non-genetic means of extending and enhancing warfighter readiness, a DARPA release said today.

Warfighters are travelers and thus suffer from travelers’ ailments including disrupted sleep cycles and limited access to safe food and water. Those who have not slept well have lower alertness, weaker athletic performance, and greater disorientation.

Current approaches to restoring wakefulness often lean on chemical methods that disrupt downstream sleep patterns and lead to exhaustion. For sustenance, warfighters typically rely on military-supplied food, which is logistically burdensome and may lead them to consume local food and water that could cause otherwise preventable diseases, notably diarrhea.

Data from 2003 to 2004 demonstrate that 2/5ths of diarrhea cases among warfighters in Iraq and Afghanistan required medical attention.

“The goal of the ADAPTER program is to produce the therapies within the body itself. ADAPTER will manage a warfighter’s circadian rhythm, halving the time to reestablish normal sleep after a disruption such as jet lag or shift lag. It will also provide safe food and water by eliminating in vivo the top five bacterial sources of traveler’s diarrhea,” described Paul Sheehan, program manager for the DARPA ADAPTER program.

Performers will choose one of two application tracks: (1) in vivo compound delivery to entrain circadian rhythm/restore sleep-cycles; or (2) in vivo decontamination of food and water from bacterial causes of traveler’s diarrhea.

A 2012 Bloomberg report said that as much as 60 percent of deployed troops in Iraq suffered from diarrhea and that one million service days in Iraq and Afghanistan were lost to the illness.
