PTSD. Four letters we immediately associate with soldiers and horrific wartime tragedies. But unfortunately, posttraumatic stress disorder (PTSD) can affect anyone who has experienced a traumatic event—including children with serious medical diagnoses. Called medical PTSD, this subgroup of the disorder can result from receiving a medical diagnosis and undergoing subsequent treatment (e.g. finding out that [...]

Magnetic Nanoparticles Could Stop Blood Clot-Caused Strokes

Each nanoparticle is composed of an iron oxide core (red squares) that is swathed in albumin (grey) and the anti-clotting agent tPA (green). The iron oxide cubes are about 20 nm on a side.

By loading magnetic nanoparticles with drugs and dressing them in biochemical camouflage, Houston Methodist researchers say they can destroy blood clots 100 to 1,000 times faster than a commonly used clot-busting technique. The finding, reported in Advanced Functional Materials (early online), is based on experiments in human blood and mouse clotting models. If the drug [...]

Brain Activity Shows Infants Are Hardwired To Link Images, Sounds As They Learn To Speak

New research examining electrical brain activity in infants suggests that we are biologically predisposed to link images and sounds to create language. In a paper published in the journal Cortex, an international team of researchers in the UK and in Japan, including those at the University of Warwick, examined the electrical activities of the brain [...]

Fever Alarm Armband: A Wearable, Printable, Temperature Sensor

The armband is 30 cm long and 18 cm wide, and can be worn either directly on the skin or on top of clothing. The device is designed so that the thermal sensor is located between the arm and the body. The organic power supply circuit is located under the piezo film speaker to reduce surface area.

University of Tokyo researchers have developed a “fever alarm armband,” a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. This armband will be presented at the 2015 IEEE International Solid State Circuits Conference, San Francisco, on 22-26 February, 2015. The flexible organic components developed for this device are well-suited [...]

‘Nanodrones’ Could Deliver Drugs To Prevent Heart Attacks

Nanometer-sized “drones” that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, according to a study in pre-clinical models by scientists at Brigham and Women’s Hospital (BWH) and Columbia University Medical Center. These findings are published in the online issue [...]
