Clinical researchers at the University of Massachusetts Medical School (UMMS) are combining an innovative constellation of technologies such as artificial intelligence, smartphone programming, biosensors and wireless connectivity to develop a device designed to detect physiological stressors associated with drug cravings and respond with user-tailored behavioral interventions that prevent substance use. Preliminary data about the multi-media device, called iHeal, was published online first in the Journal of Medical Toxicology.
According to the study's authors, many behavioral interventions used to treat patients are ineffective outside of the controlled clinical settings where they are taught. This failure can be attributed to several factors, including a patient's inability to recognize biological changes that indicate increased risk of relapse and an inability to change their behaviors to reduce health risk.
Edward Boyer, MD, PhD, professor of emergency medicine at UMass Medical School and lead author of the study, worked with colleagues at UMMS and at the Massachusetts Institute of Technology, to design a mobile device using so-called "enabling technologies" that could be used to make behavioral interventions for substance abusers more effective outside the clinic or office environments. The result of their work, iHeal, combines sensors to measure physiological changes and detect trigger points for risky health behaviors, such as substance use, with smartphone software tailored to respond with patient-specific interventions.
Individuals with a history of substance abuse and post-traumatic stress disorder were asked to wear an iHeal sensor band around their wrist that measures the electrical activity of the skin, body motion, skin temperature and heart rate – all indicators of stress. The band wirelessly transmits information to a smartphone, where software applications monitor and process the user's physiological data. When the software detects an increased stress level, it asks the user to annotate events by inputting information about their perceived level of stress, drug cravings, and current activities. This information is then used to identify, in real-time, drug cravings and deliver personalized, multimedia drug prevention interventions precisely at the moment of greatest physiological need.
Boyer and his teams examined the iHeal system architecture, as well as preliminary feedback from initial users, to identify key attributes and assess the device's viability. Their analyses suggest a number of technical issues related to data security, as well as the need for a more robust and less stigmatizing version before the device could be worn in public.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
