Full-Color 3D Printing, Poised to Change the Game for Businesses Everywhere

While full-color 3D printing has been around for many years, it is now gaining meaningful traction. In part this is because next-generation technologies are entering the market, offering capabilities that improve quality and performance, while at the same time helping to reduce cost. Soon affordable, high-quality color 3D printing will benefit organizations in many different industries by allowing them to innovate more quickly, improve the performance of their current products, and generate new revenue while simultaneously decreasing their manufacturing and supply chain costs.

Tuning in to Antenna Design

Using engineering simulation, big compute and 3-D printing, Optisys achieves orders-of-magnitude reduction in antenna size and weight while reducing development time. By leveraging ANSYS electromagnetic and structural simulation tools running on Rescale’s big compute platform, this startup’s engineers take full advantage of the design freedom offered by 3-D printing to meet radio frequency (RF) performance requirements for an integrated array antenna.

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.

Blast-Induced Acceleration in a Shock Tube

High-fidelity simulation of blast flow conditions can aid in developing strategies to mitigate blast-induced brain injury.

The prevalence of blast-induced traumatic brain injury (bTBI) has prompted an urgent need to develop improved mitigation strategies and advance medical care targeting casualties with bTBI. Despite considerable effort, the basic mechanisms of blast-induced brain injury are still undefined. Based largely upon computational modeling, several candidate mechanisms of nonimpact bTBI have been identified and include head acceleration. This work hypothesizes that explosion flow conditions can cause head acceleration sufficient to injure the brain, and that these inertial forces combine with other injury mechanisms to yield bTBI.

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.

Wireless Vital Signs Monitor for Trauma Patients

A miniature, portable wireless vital signs monitor (MWVSM), called Mini-medic™, could aid in the triage and diagnosis of trauma patients with and without traumatic brain injury (TBI). The MWVSM consists of two components, both of which are the approximate size and weight of a cellphone: one is a sensor that is placed either on the forehead or the fingertip of a patient, and the other is a monitor that receives a wireless signal transmitted up to 100 m carried by the medic.
