  • Paper sensors remove the sting of diabetic testing December 21, 2018
    A technique that enables biologically active enzymes to survive the rigors of inkjet printing presents a promising alternative to routine blood screening finger jabs for diabetic blood sugar levels. The KAUST-led team used this approach to make disposable devices that can measure glucose concentrations in human saliva.
  • Micropores let oxygen and nutrients inside biofabricated tissues December 20, 2018
    Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, according to a team of Penn State researchers.
  • Understanding dynamic stall at high speeds December 18, 2018
    When a bird in flight lands, it performs a rapid pitch-up maneuver during the perching process to keep from overshooting the branch or telephone wire. In aerodynamics, that action produces a complex phenomenon known as dynamic stall. Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process […]
  • Pushing lithium ion batteries to the next performance level December 13, 2018
    Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international scientists have developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries. […]
  • To guide cancer therapy, device quickly tests drugs on tumor tissue December 12, 2018
    MIT researchers have 3-D printed a novel microfluidic device that simulates cancer treatments on biopsied tumor tissue, so clinicians can better examine how individual patients will respond to different therapeutics—before administering a single dose.
  • Researchers devise 3-D printer that can make energetic materials safer, more environmentally friendly December 7, 2018
    Purdue University researchers have devised a method of 3-D printing that can produce energetic materials with fine geometric features faster and with less expense than traditional methods, while also being safer and more environmentally friendly.
  • How engineers are straightening the Leaning Tower of Pisa December 2, 2018
    "It's still straightening," said engineer Roberto Cela, gazing at the Leaning Tower of Pisa gleaming in the autumn sunshine of northern Italy. "And many years will have to pass before it stops."
  • Cranking up the power setting may help some who use prosthetics November 8, 2018
    Amputees who use powered prosthetic ankles may be able to avoid the energetic costs typically associated with prosthetics by cranking up the power provided by their devices.
  • Electroanatomical mapping with non-thrombogenic, stretchable and active multielectrode arrays (MEAs) November 6, 2018
    To evaluate in vivo physiological functions, electrophysiological signals must be monitored with high precision and high spatial or temporal resolution. Ultraflexible, multielectrode arrays (MEAs) were recently fabricated to establish conformal contact on the surfaces of organs and to measure electrophysiological signal propagation at high spatial-temporal resolution. However, plastic substrates with a high Young's modulus incorporated […]
  • Permanent, wireless self-charging system using NIR band October 8, 2018
    As wearable devices are emerging, there are numerous studies on wireless charging systems. Here, a KAIST research team has developed a permanent, wireless self-charging platform for low-power wearable electronics by converting near-infrared (NIR) band irradiation to electrical energy. This novel technology can be applied to flexible, wearable charging systems without needing any attachments.
