Blood Test Detects Multiple Types of Cancer

  • Magazine Article
  • TBMG-36176
Published 2020-03-01 by Tech Briefs Media Group in United States

A new blood test uses next-generation sequencing technology to probe DNA for tiny chemical tags (methylation) that influence whether genes are active or inactive. When applied to nearly 3,600 blood samples — some from patients with cancer and some from people who had not been diagnosed with cancer at the time of the blood draw — the test successfully picked up a cancer signal from the cancer patient samples and correctly identified the tissue from where the cancer began (the tissue of origin). The test’s specificity — its ability to return a positive result only when cancer is actually present — was high, as was its ability to pinpoint the organ or tissue of origin.

Portable Sample Preparation for Chemical and Biological Analysis

Outsourcing Plasma Treatments for Surface Modification

Aerospace & Defense Technology: February 2020

  • Magazine Article
  • 20AERP02_02
Published 2020-02-01 by SAE International in United States

In manufacturing, plasma treatments are often utilized to solve problems that cannot be resolved other ways. Whether attempting to improve adhesion of dissimilar materials; depositing coatings; cleaning surfaces; applying a protective coating that repels water, for example, or biological fluids; or enhancing surface wettability or functional coating, plasma treatments often add significant value to products.

Using Plasma Treatments to Improve, Enhance Medical Devices

  • Magazine Article
  • TBMG-36014
Published 2020-02-01 by Tech Briefs Media Group in United States

Whether attempting to improve adhesion of dissimilar materials, depositing coatings, cleaning surfaces, applying a protective coating that repels water for example or biological fluids or enhancing surface wettability or functional coating, plasma treatments often add significant value to medical devices.

Insect-Inspired Motion Sensing

  • Magazine Article
  • TBMG-35993
Published 2020-02-01 by Tech Briefs Media Group in United States

Researchers have taken inspiration from flying insects to demonstrate a miniaturized gyroscope, a special sensor used in navigation technologies. Gyroscopes sense rotational motions to provide directional guidance without relying on satellites, so they are immune to signal jamming and other cyber threats, making them ideal for aircraft and submarines.

Robot Circulating Liquid Stores Energy and Provides Power

  • TBMG-36003
Published 2020-02-01 by Tech Briefs Media Group in United States

Humans and other complex organisms manage life through integrated systems. Humans store energy in fat reserves spread across the body and an intricate circulatory system transports oxygen and nutrients to power trillions of cells. But with an untethered robot, things are much more segmented with batteries, motors, and cooling systems scattered throughout.

3D Printing Technique Produces “Living” 4D Materials

  • Magazine Article
  • TBMG-35958
Published 2020-02-01 by Tech Briefs Media Group in United States

Repairing and reusing plastics and delivering cancer drugs more effectively are two of the many potential applications a new 3D/4D printing technology might have. The technology merges 3D/4D printing and photo-controlled/living polymerization — a chemical process to create polymers. 4D printing is a subset of 3D printing where the printed object can transform its shape in response to certain conditions. The new method uses visible light to create an environmentally friendly “living” plastic or polymer. Polymers can be synthetic, such as plastic, as well as biological; for example, DNA.

In-Situ Resource Utilization (ISRU): Methylotrophic Microorganisms Expressing Soluble Methane Monooxygenase Proteins

  • Magazine Article
  • TBMG-35812
Published 2020-01-01 by Tech Briefs Media Group in United States

Long-duration missions to planetary bodies and deep space will require new technological developments that support human habitation in transit and on distant bodies. Microorganisms are unique from the standpoint that they can be employed as self-replicating bio-factories to produce both native and engineered mission-relevant bio-products. Methane (CH4) usage in In-Space Manufacturing (ISM) platforms has been discussed previously for human exploration and has been proposed to be used in physicochemical systems as a propulsion fuel, supply gas, and in fuel cells.
