Researchers Show How Fear Memories Can Be Erased

Researchers at the University of California, Riverside have devised a method to selectively erase particular fear memories by weakening the connections between the nerve cells (neurons) involved in forming these memories. A sight, sound, or smell we have sensed may not later trigger fear, but if the stimulus is associated with a traumatic event, such as a car accident, then fear memory is formed, and fearful responses are triggered by the stimulus.

Painless Microneedles Extract Fluid for Wearable Sensors for Soldiers

Sandia National Laboratories and University of New Mexico researchers have developed unique microneedle-based sensor technology that they hope can someday be used to help soldiers on vital missions. Ronen Polsky, a Sandia materials scientist who leads the design of the microneedle sensor, said the technology is the first way to extract large volumes of pure interstitial fluid for further study.

The 3D Printing Landscape: Then and Now

Frequently used as a design validation and prototyping tool in its early days, the 3D printer now supports a much wider range of applications, from shape-conforming electronics to the creation of printed living tissue. Tech Briefs spoke with industry expert Terry Wohlers about 3D printing's emerging possibilities.

Electric Patch Holds Promise for Treating PTSD

An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study — survivors of rape, car accidents, domestic abuse and other traumas — an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.

Wireless Sensor Enables Study of Traumatic Brain Injuries

A new system that uses a wireless implant has been shown to record – for the first time – how brain tissue deforms when subjected to the kind of shock that causes blast-induced trauma commonly seen in combat veterans.

MIT Provides Yeast a Different Environment for Ethanol Tolerance

Ethanol and other alcohols can disrupt yeast cell membranes, eventually killing the cells. In research funded by the MIT Energy Initiative and the U.S. Department of Energy, researchers at MIT and the Whitehead Institute for Biomedical Research found that adding potassium and hydroxide ions to the medium in which yeast grow can help cells compensate for that membrane damage.
